2. About Your Black+ Decker Electric Tankless Water Heater

Congratulations on making the decision to purchase one of the best and nest Instant Water

Heaters currently available in the market today! Your new Instant Water Heater features advanced

water ow rate and temperature sensors which are designed to modulate power to the heating

elements to maintain a user-selected output water temperature range for 36 KW: 86°F (30°C) to

140°F (60°C) (subject to the temperature of the incoming water).

WARNING: When selecting the water temperature setting of your Instant Water Heater’s

thermostat, factors such as safety and energy conservation should be considered. Continuous

exposure of the skin to water temperatures above 120°F (49°C) can result in severe burns or

death. The maximum temperature to be set on this Instant Water Heater’s thermostat is 140°F

(60°C). Always take precaution to feel the water before bathing or showering to make sure the

temperatures are not too hot. You are required to read and comply with the Time/Temperature

Relationship Chart on the following page to determine the right water temperature for your home.

5. Plumbing Requirements and Precautions

• Please follow all plumbing instructions carefully. This product must be installed in accordance

with all national, state, provincial, and local plumbing codes. We recommend consulting with

your municipality or a qualied plumber if you have questions relating to plumbing codes for

your area prior to installing.

• The plumbing installation must be completed before the electrical installation.

• DO NOT solder any pipe with the unit connected to the pipe. The

heat from soldering may cause damage to the ow sensor. Doing so

will void the warranty.

• The use of a temperature pressure relief valve (T&P) is not required for

most installations because the tankless water heater does not use a

storage tank. UL Standard 499 does not require that a pressure relief

valve is used, although it may be needed to meet installation codes in

your area. In such cases, the pressure relief valve should be installed

in accordance with local codes. It is important to ensure that the unit

is operating correctly, and that air is purged from the valve prior to installing the water heater.

• A T&P valve is recommended for added safety when connecting to plumbing rated Metal,

Flex or High-Temperature CPVC piping.

NOTE: A pressure relief valve is required for installations in the Commonwealth of

Massachusetts and State of Kentucky. Please check your local installation codes

for any special requirements.

• The plumbing installation requires piping that can withstand pressure up to 8 BAR.

• The maximum operating water pressure for this unit is 150PSI / 10BAR. Residential plumbing

systems with unstable pressure or pressure above 5 BAR require the application of a pressure

reduction valve set to 4-5 BAR for optimal performance.

• The water supply ow rate must be at least 0.5 Gallons per Minute (GPM) to ensure proper

operation.

• Flexible water hoses are recommended to be used with your water heater when installing

your water heater. When connecting the inlet water pipe to the unit, use a wrench to hold the

unit’s connection, and another wrench to tighten so that the ow sensor on the unit will not

be loosened or damaged. Do not over-tighten the water inlet and outlet connections to avoid

severe internal damage to the water heater.

• We recommend the installation of a manual shut-o valve (ball valve) on the inlet and outlet

of the water heater to create a convenient shut-o point if future maintenance or servicing

is required. Before connecting the pipes to the water heater, it is highly essential to ush

the lines to eliminate all the plumbing paste or residue in the lines caused by any welding or

soldering.

• All the water pipes within 3 feet (1 meter) of the inlet and outlet connections are recommended

to be rated for high-temperature applications with 150°F (66°C) minimum.

• Before proceeding to the electrical installation, run water through the unit for several minutes

to ush out any air bubbles from the water line.

6. Plumbing Installation

STEP 1: Thoroughly ush cold supply line of debris.

STEP 2: Connect the HOT WATER line to the water heater OUTLET. The water heater outlet can

be seen on the left side of the heater when facing the unit. Connect the COLD-WATER line to the

water heater marked COLD WATER INLET which is located on the right side when facing the unit.

* Pre-heated water can be connected to the cold water inlet, where this unit will act as a booster.

STEP 3: After tightening both ttings at the water heater, several hot water faucets should be

opened to allow the ow of water through the water heater for at least 2 to 3 minutes. This process

purges all the air from the water lines and MUST be performed before turning on the power at the

unit.

FAILURE TO FOLLOW THIS STEP MIGHT CAUSE PERMANENT DAMAGE TO THE HEATING

ELEMENTS. (The power to the heater should be turned o and the air purged out of the lines

before turning the power on anytime maintenance is performed on the water heater or the homes

plumbing system, as air might have been introduced into the plumbing pipes.)

STEP 4: Carefully inspect all connections, units, and the pressure relief device for leaks after the

plumbing installation is completed. If there are no leaks present, you can proceed to the electrical

installation.

CAUTION: If you detect a water leak from the water heater at this point, turn o the water

supply at the shut o valve on the unit’s incoming water supply and contact us at 1-844-746-6688.

7. Electrical Requirements and Precautions

Manufacturer recommends that this product be installed in accordance with all applicable national,

state, provincial, and local electrical codes. Consult a qualied and licensed electrician if you have

questions or are unsure about anything relating to codes for this product. The heater must be

connected to a dedicated circuit breaker on the main electrical panel.

WARNING: As with all electrical appliances, it’s crucial to rst shut o all power to the unit

directly at the fuse or breaker box before attempting to install, repair or disassemble this water

heater. Ensure that the breaker is shut o. SERIOUS BODILY INJURY OR DEATH COULD OCCUR

IF YOU IGNORE THIS WARNING.

CAUTION: All wiring (wire gauge), as well as circuit protection (breaker), must comply with

the U.S. National Electrical Code (NEC) in the USA or the Canadian Electrical Code (CEC) in

Canada. Failure to do so could lead to property damage, personal injury, and void your warranty.

Note: The Canadian Electrical Code generally requires that all supply wires and corresponding

circuit protection used for domestic hot water heating and hydronic heating applications be sized

to a minimum of 125% of the maximum current rating of the heater (check heater specication

details below).

Before installing this tankless water heater, ensure that sucient electrical power is available

in the home to handle the maximum amperage load of the applicable heater.

IMPORTANT NOTES:

36kW heater requires 3 set of wire and ground (see wiring diagram on page 11)

• Please see electrical specications by heater input and wiring diagram on the page 11 for

additional electrical information.

STEP 1: Take the wire pair and connect to the breaker (see wiring diagram). Be sure that the

breaker is connected to one black wire and one red wire. Be sure the power to the unit is shut o

using the dedicated circuit breakers in the main electrical panel.

STEP 2: Run the correct set of power cable wires from the circuit breaker in the main electrical

panel to the water heater by utilizing a suitable wire gauge which meets all applicable electrical

codes for the size of the breaker. Then, connect the power cable to the block terminal within the

water heater.

STEP 3: Unit requires a ground conductor for the incoming circuit.

STEP 4:

DOUBLE CHECK the electrical connections and ensure the wire connections are

correct, tight and secure. It’s important to conrm that the right breaker size and wire gauge has

been used and that the unit has been connected to a ground in accordance with applicable codes.

Be sure to reattach the front cover of the unit with two screws.

STEP 5: Ensure that all the air has been purged from the water lines before turning on power to

the unit. Refer to STEP 3 in the plumbing installation section. Restore power to the unit through

the dedicated circuit breaker in the main electrical panel.

It is crucial to follow the wire connection as shown and ensure all connections are made

correctly for proper operation of the unit. The unit will not operate correctly, even though it

turns on and otherwise appears to function, if you mix up one set of wire with another.

10. Operation Guide

Operating your new tankless water heater is similar to using any traditional water heating system.

However, it is essential that you carefully read all setup procedures, operating instructions and

tips to ensure the maximum performance and energy savings from your new water heater. We

recommend that all members of the household read these General Operating Instructions.

This electric water heater is designed to supply hot water. The unit contains heating elements within,

capable of heating water quickly on-demand for as long as you need it. Unlike a conventional tank

storage water heater, this unit is a tankless water heater that does not store hot water. However,

once you begin using the system, you will understand it works like a conventional tank system.

Tankless system delivers hot water instantaneously on demand. Since a tankless system does not

waste energy continually when heating water, i.e. idly sitting and losing heat in a storage tank, it

provides signicant energy savings than a conventional water heater.

With your new system, as soon as you turn on the hot water faucet, the demand for hot water is

detected by a ow sensor, and the high-power heating elements are activated. Sensors continually

monitor the water ow rate and measured the incoming and outgoing water temperature. Data is

transmitted to the system logic controls, which determines the exact amount of power required by

heating elements to heat the water to your desired temperature.

It is essential to keep in mind that all tankless water heaters are subject to a maximum ow rate. If

this ow rate is exceeded, the heater will not be capable of suciently heating water.

Also keep in mind that conventional tank heaters are set to high temperatures to prevent running

out of hot water quickly, and thus a large amount of cold water needs to be mixed in to reach a

comfortable level for washing and showering. Since this unit heats water on demand, it is designed

to heat to a lower temperature. This means you only need to mix in a small amount of cold water

or none at all.

Your hot water supply may also be aected by the incoming water temperatures as the season

diers. During winter, if the incoming water temperature is frigid, you might not be able to run

multiple hot water outlets at the same time as compared to the summer. However, you can run

showers back-to-back without having to wait for the water to heat.

Water Quality: One of the things which should be taken into consideration when installing and

maintaining the water heater is the quality of water. Water conditions outside the recommended

levels outlined below are not permitted and can damage the water heater. We reserve the right to

deny any warranty claim regarding damage suered due to use in water conditions that are not

13

in accordance with the table below. The water must be treated, and the heater ushed regularly

when this product is installed in an area that is known to have hard water that causes scale build-

up to prevent damage to the heat exchanger and heating elements. We recommend that a water

treatment device or water softener should be installed to maintain optimal performance of the

water heater in hard water areas.

11. Care and Maintenance

To ensure maximum performance of your water heater and to reduce the risk of a water leak, we

recommend the following maintenance:

• The water heater has minimally required maintenance procedures. Periodic inspections and

tests are always recommended for signs of damage or failure. Any damage, cracks, leakage

or weakness should be addressed and xed immediately. Do not over tighten any of the

connections. Over tightening the connection points could cause severe internal damage to

the unit.

• Remember that water heated at higher temperatures produces scale buildup much faster

than at lower temperatures. Having manual shut-o/maintenance valves installed on the inlet

and outlet of the water heater will allow access to ush the unit with a descaling solution. We

recommend routine maintenance once a year or once every six months if the water supply

has an unusually high level of mineralization (hard water)

• Clean the pre-lter on the inlet water side once every six months. Wash lightly to remove any

debris.

When any form of maintenance is carried out on the water heater or the home’s plumbing system

that may introduce air into the plumbing pipes, it is crucial to power o the water heater and purge

the air out of the lines before allowing the unit to power up.

FAILURE TO DO SO COULD RESULT IN PERMANENT DAMAGE TO THE HEATING ELEMENT

AND VOID YOUR WARRANTY.

When air is introduced into the plumbing system, follow the steps below to ensure the unit can

safely resume operation.

1. Shut o all power connections to the unit at the circuit breaker on the main electrical panel.

2. Perform the maintenance or servicing tasks.

3. Open one or more hot water faucets and allow water to run through the unit for several

14

minutes to purge any air from the heater and water lines.

This step must be performed before turning on power to the heater. Failure to complete

this step may cause permanent damage to the heating elements.

4. Reconnect power to the unit at the circuit breaker on the main electrical panel. Press and

switch the ON position.

5. With the water running through the unit, check and reset the temperature if necessary. The

recommended temperature setting is 118°F (48°C).

Reduce the water ow rate at the faucet or slightly close

the shuto valve on the unit’s incoming water supply line

to reduce the water ow rate.

Voltage less than 240

Volts

The heating elements on your water heater are designed

for 240 volts. When used with a lower voltage, they

produce less heating power. You may need to upgrade

to a larger input heater.

Crossed Wires. If it’s a new installation, double check the wiring to

conrm that it is correct.

Increase the temperature setting on the unit.

Water pressure is less

than 0.5 BAR (7 psi).

Make sure the shuto valve is fully open, and the water

supply line is not blocked.

Mixing too much cold

water

You do not need to mix as much cold water with your

tankless water heater compared to when you use a

conventional water heater. You may also have an anti-

scald feature on your faucet that is mixing cold water.

These types of faucets can usually be adjusted to reduce

the amount of cold water mixed.

Thermal loss due to

long pipe run.

As the hot water from the heater runs through the hot

water delivery system to your faucet, some heat will be

lost especially if it has long distance to travel or the pipes

are cold. This is normal. You can compensate for this by

increasing the setting on your water heater if you need/

want hotter water.

17

Water is

LIMITED WARRANTY

For service, repair or any questions regarding your water heater, call the appropriate 800 number

listed within this section. Please DO NOT return the product to the place of purchase. Also, DO

NOT mail the product back to the manufacturer, nor bring it to a service center without proper

instructions and permission from one of our representatives.

The terms of this warranty are solely subject to the original owner and are at no time transferable. A

transfer of ownership will result in immediate termination of this warranty. This warranty is valid only

if the product is purchased from an authorized reseller that has an established direct relationship

with the manufacturer.

The manufacturer warrants to the original owner that our instant water heaters will be free from

defect in workmanship and material for TWO YEARS from the date of purchase, and free from

leakage for SEVEN YEARS from the date of purchase. Should any part(s) prove to be defective

during this period, the manufacturer will only be responsible for a replacement water heater or

replacement of the defective part(s). The manufacturer is not responsible for labor charges or any

incidental or consequential expenses. If a replacement water heater or part is not available, the

manufacturer’s liability is limited to the cost of the water heater or $1,000.00, whichever is less.

The manufacturer is not an insurer, and the original owner should purchase insurance to cover

damage to property or belongings. The original owner agrees to waive their right to jury trial or to

participate in a class action. Also, the original owner agrees to waive subordination to the extent a

loss is covered by insurance, so that their insurance company cannot proceed with action against

the manufacturer for recovery of any claims. Furthermore, all requests must be arbitrated in the

state of New Jersey.

Should the owner wish to return the water heater for repair, the owner must rst secure written

authorization from the manufacturer. The owner shall be required to show proof of purchase date

and to pay all transportation costs to return the defective part(s) or water heater for repair or

replacement. Warranty is void if: (i) water heater has been installed or used improperly; (ii) design

has been altered in any way; (iii) water heater has been installed and/or serviced by someone other

than a licensed electrician; (iv) or if the water heater has been installed or used in contradiction to

installation instructions, applicable laws and/or ordinances.
