Installation, Operation and Care Of

AM16 DISHWASHERS

SAVE THESE INSTRUCTIONS

GENERAL

Models AM16-BAS, AM16T-BAS, AM16VL-BAS, AM16VLT-BAS, AM16-ASR, AM16T-ASR,

AM16VL-ADV, AM16VLT-ADV, AM16SVLT, AM16SCB, AM16VLSCB dishwashers can be

congured for both straight through or corner operation. AM16-BAS, AM16T-BAS, AM16VL-

BAS, AM16VLT-BAS, AM16-ASR, AM16T-ASR, AM16VL-ADV, AM16VLT-ADV, AM16SVLT,

AM16SCB, AM16VLSCB dishwashers are shipped from the factory in straight through

conguration. Straight through machines can be easily converted to corner operation.

The AM16-BAS, AM16T-BAS, AM16VL-BAS, AM16VLT-BAS, AM16-ASR, AM16T-ASR,

AM16VL-ADV, AM16VLT-ADV, AM16SVLT dishwashers are designed to operate in hot water

sanitizing mode only (Designated by the NSF temperature requirements of 150°F Wash and

180°F Rinse. These temperatures can be found on the label located under the touchscreen

controls on the lower part of the machine).

The AM16SCB, AM16VLSCB dishwashers are designed to operate in chemical sanitizing

mode only (Designated by the NSF temperature requirements of 120°F Wash and 120°F

Rinse. These temperatures can be found on the label located under the touchscreen controls

on the lower part of the machine).

The serial number can be found on the machine data label located at the bottom of the front

right leg of the machine.

Hobart supplied chemical pumps ship standard with all AM16SVLT, AM16SCB and

AM16VLSCB models. Chemical pumps are available as an accessory kit (eld installed)

for all other models or contact your chemical representative for a chemical feeder system

to be supplied and installed by others.

The wash pump motor is rated 2 H.P. and has thermal overload protection.

The ll line incorporates an air gap on all models to prevent any reverse ow of water from

the dishwasher into the potable water supply. The unit, once turned on, lls the wash tank

to the appropriate level and automatically stops lling once the level is reached. A pressure

transducer reads the water level in the wash tank and shuts off the heat supply if the water

level becomes too low. When the water returns to the proper level, the heating circuit

becomes operational again.

An automatic pumped drain and pumped rinse system are standard on all models.

A frame mounted 7.1kW electric booster water heater is equipped on all hot water sanitizing

models. The booster water heater is designed to maintain a minimum nal rinse temperature

of 180°F provided the incoming water is at least 110°F. For ventless models AM16VL-BAS,

AM16VLT-BAS, AM16VL-ADV, AM16VLT-ADV and AM16SVLT, the booster water heater is

designed to maintain a minimum nal rinse temperature of 180°F with cold incoming water

of at least 55°F.

Models AM16SCB and AM16VLSCB are provided with a 4.3kW electric booster water heater.

The booster water heater is designed to maintain a minimum nal rinse temperature of 120°F

provided the incoming water is at least 90°F (120°F recommended).

Ventless Models AM16VL-BAS, AM16VLT-BAS, AM16VL-ADV, AM16VLT-ADV and

AM16VLSCB do not require a vent hood. They use an internal condensing system to minimize

the water vapor escaping from the unit during loading and unloading. High-temperature

AM16-BAS, AM16T-BAS, AM16-ASR, AM16T-ASR models typically require a hood or vent

– 5 –

over the dishwasher to meet local codes. Low-temperature chemical sanitizing machines

or low usage electric heat dishwashers may not require individual venting of the machine

if the room is amply exhausted. Refer to pages 11 - 12 for venting and hood requirements.

Verify with local code ofcials for nal determination.

Models AM16-ASR, AM16T-ASR, AM16VL-ADV, AM16VLT-ADV and AM16SVLT

are equipped with an Automatic Soil Removal (ASR) system. The ASR system automatically

redirects food soil left over after pre-scrapping to an external scrap basket located at the right

side of the machine (accessory available for left hand installation). This helps to keep the

wash water cleaner, reducing the frequency of water changes. This saves water, energy, and

chemicals. The AM16-ASR-Series machines are only available in hot water sanitizing mode.

Models AM16VL-ADV, AM16VLT-ADV and AM16SVLT require a single cold-water supply

and come equipped with a drain water energy recovery system which includes drain water

tempering. They utilize a heat exchanger to capture the energy from the drain water and

preheat the incoming cold water for the nal rinse. The AM16VL-ADV, AM16VLT-ADV and

AM16SVLT are also equipped with an ASR system.

INSTALLATION

UNPACKING

Immediately after unpacking the dishwasher, check for possible shipping damage. If this

machine is found to be damaged, save the packaging material and contact the carrier

within 5 days of delivery.

NOTE: Use caution when using a forklift to remove machine from skid. DO NOT use door

lift handle to move machine, as it will cause door lift issues.

Prior to installation, test the electrical service to ensure it agrees with the specications

on the machine data plate. The dishwasher data plate is located at the lower right hand

corner of the machine.

INSTALLATION CODES

LOCATION

Before nalizing the location, make sure that consideration has been given for the

electrical conduit, water supply, drain connection, venting (if applicable), tabling (if needed),

chemical feeder replenishment (if applicable) and adequate clearance for opening the door.

The dishwasher must be level before any connections are made. Turn the threaded feet

(Fig. 1) as required to level the machine and adjust to the desired height.

The edge of dish table that overhangs the AM16 wash tank should be turned down and

tted over the top of the dishwasher tank (Fig. 2). Apply an NSF approved sealant between

the overhang of the dish table and the inner wall of the wash tank to prevent leakage

(Fig. 2). Fasten the dish tables to the inner wall of the wash tank with non-rusting truss

head screws or rivets (Fig. 2).

For straight-through installations, 30" clearance at the front and 15" clearance at the right

side by 29-1/2" clearance above the nished oor must be provided for service.

For machines equipped with ASR, 30" clearance at the front and 24" clearance at the right

side (or left if ASR is relocated to left side) by 33" clearance above the nished oor must be

provided for service. If ASR is relocated to left side, then 15" clearance is required at right side.

NOTE: For 480-volt units, 20" clearance required at left side.

Based on dish table design, rear table brackets (Fig. 3) may need to be adjusted or removed.

Loosen the two bolts and nuts and adjust or remove as required.

NOTE: For AM16-ASR, AM16T-ASR, AM16VL-ADV, AM16VLT-ADV and AM16SVLT models,

PLUMBING CONNECTIONS

Plumbing connections must comply with applicable sanitary, safety

and plumbing codes.

Water Requirements

Proper water quality can improve ware washing performance by reducing spotting, enhancing

effectiveness of labor and extending equipment life. Water conditions vary from one location

to another. The recommended proper water treatment for effective and efcient use of this

equipment will also vary depending on the local water conditions. Ask your municipal water

supplier for details about local water conditions prior to installation.

Recommended water hardness is 3 grains of hardness per gallon or less. Higher hardness

may cause excessive formation of lime scale. Water hardness above 3 grains per gallon

requires water treatment. Water treatment has been shown to reduce costs associated with

machine cleaning, reduce deliming of the dishwasher and reduce detergent usage in the

dishwasher. Chlorides must not exceed 50 ppm.

– 9 –

High iron levels in the water supply can cause staining and may require

an iron lter. High chloride levels in the water supply can cause pitting and may

require a chloride removal system. Contact you local water treatment professional

for proper water treatment.

Sediment may require a particulate lter. Dissolved solids may require water treatment

such as a water softener, reverse osmosis system, etc. Contact your local water treatment

professional for proper water treatment.

If an inspection of the dishwasher or booster heater reveals lime build-up after the equipment

has been in service, water treatment is recommended. If a water softener is already in place,

ensure there is a sufcient level of salt. Contact your Hobart Service ofce for specic

recommendations.

Water Supply Connection

The plumber connecting this machine is responsible for making certain that water lines are

THOROUGHLY FLUSHED OUT BEFORE connecting to the dishwasher. This "ush-out" is

necessary to remove all foreign matter, such as chips (resulting from cutting or threading of

pipes) pipe joint compound from the lines; or, if soldered ttings are used, bits of solder or

cuttings from the tubing. Debris, if not removed, may lodge in the dishwasher's plumbing

components and render them inoperative. Manual valves or solenoid valves fouled by

foreign matter and any expenses resulting from this fouling are NOT the responsibility of

the manufacturer and associated repair costs are not covered under warranty.

Water supply requirements are as follows:

AM16-ASR, AM16T-ASR and AM16VLSCB models require both a cold water supply and

a hot water supply.

On AM16VL-BAS, AM16VLT-BAS, AM16VL-ADV, AM16VLT-ADV, AM16SVLT

and AM16VLSCB installations, the cold water supply must not exceed 90° F (32° C) for

proper operation. Optimal results are obtained when cold water supply temperature

is below 65° F (18° C). For best results, it may necessary to use 1/2" pipe for cold

water pipe size and minimize the distance between the dishwasher and the entrance

into the building. Pipe insulation will also improve results.

WATER SUPPLY REQUIREMENTS

– 10 –

If cold water supply temperature is consistently above 90° F (32° C) or if excessive water

vapor or steam is entering the dish room after the condensing cycle is complete, contact

Hobart Service to increase condensing time.

Required owing water pressure to the dishmachine is 15 – 65 PSIG. If owing pressures

higher than 65 PSIG are present, a pressure regulating valve must be installed in the water

line to the dishmachine (by others). If owing pressure is less than 15 psi, improper machine

operation may result. All AM16 models are equipped with a pumped rinse system; therefore,

a water pressure gauge is not required and is not supplied with the machine.

The water pressure regulator must have a relief bypass. Failure to use

the proper type of pressure regulator may result in damage to the unit.

A manual shutoff valve (not supplied) should be installed upstream of the ll hose to

accommodate servicing the machine. It is recommended that a line strainer (not supplied)

be installed in the supply line between the manual shutoff valve (not supplied) and the

connection point on the machine.

All machines ship standard with a 96" long stainless steel braided ll hose with a 3/4" female

garden hose tting. A second ll hose is shipped for machines equipped with both hot and

cold water connections. Make plumbing connections with 1/2" minimum copper piping OD

(3/4" recommended), with a 3/4" male garden hose tting (not supplied).

Drain Connection

A drain hose, 5/8” inside diameter and 6’ long, is provided with machine. This should be

securely plumbed into a drain. Use care not to kink the hose. Drain must have a minimum

ow capacity of 18.5 gallons per minute. The drain hose height cannot exceed 40” above

nished oor.

If a grease trap is required by code, it should have a minimum ow capacity of 18.5 gallons

per minute.

If machine is equipped with ASR, use supplied pumped drain air gap kit (part # 00-562723-

00001) shipped with machine; refer to installation instructions included with kit. For -BAS

and VL-BAS models, pumped drain air gap kit is available through sales using accessory

code PMP-DRAIN-AM16 or service kit part # 00-562723-00002.

NOTE: If machine is equipped with ASR, DO NOT plumb ASR drain line to 3-comp

sink drain.

VENTING REQUIREMENTS

NOTE: Any listed and labeled factory-built commercial exhaust hood tested in accordance

with UL Standard 710 by a nationally recognized testing laboratory, must be installed

according to the terms of its listing and the manufacturer’s installation instructions.

Rate of Exhaust Flow Calculations

Based on the 2018 International Mechanical Code.

The minimum net airow for Type II hoods used for dishwashing appliances shall be 100

cfm per linear foot of hood length. The net quantity of exhaust air shall be calculated by

subtracting any airow supplied directly to a hood cavity from the total exhaust ow rate of

a hood.

Ventless models AM16VL-BAS, AM16VLT-BAS, AM16SVLT, AM16VL-ADV, AM16VLT-ADV

and AM16VLSCB do not require a Type II vent hood. According to 507.3 of the 2018 IMC,

Type II hoods are not required where the heat and moisture load is incorporated into the

HVAC system design. See Table A (page 12) for heat dissipation or heat gain to space.

• The AM16 machine factory detergent default is to 2.5 ml/L which corresponds to 6.25 ml/cycle and 5.7 pump

revolutions based on KAY QSR Machine Warewashing Detergent (yellow color). Other detergents may

require dose change.

• The above chemicals dose info in the table is only a guide.

• In the above table, the doses of “ml/L" and "ml/cycle" and their corresponding "pump revolutions and on-times"

are based on the respective manufacturer's dose recommendations (obtained from a detergent's MSDS/SDS or

Technical Data Sheet) and the AM16 rinse water volume of 0.67 gal/cycle.

• For detergents with known % dilution, calculate "ml/L" by multiplying the known % dilution by 10 e.g., 0.20 % to

ml/L is 0.20 % * 10 = 2.0 ml/L.

• For detergents not listed in the table and dose unknown, use the detergents dose of “1.5 ml/L which

corresponds to 3.8 ml/cycle" or work with the chemical vendor for the recommended dose.

• With the information on "ml/L", calculate "ml/cycle" by multiplying the known "ml/L" by 2.535 e.g., "2.0 ml/L" to

"ml/cycle" is 2.0 ml/L* 2.535 = 5.07 ml/cycle).

• The factor "2.535 (i.e., 0.67 gal/cycle * 3.785 L/gal) " is based on the AM16 rinse volume of 0.67 gal/cycle and the

conversion of "gal" to "L". The factor should change when the rinse volume changes.

7. To exit the programming, use the Up and Down Arrows to scroll thru the parameters until

‘back’ is outlined and press the ‘Enter’ button. Repeat this procedure until the Ready

screen is displayed.

• The AM16 machine factory rinse aid default is set to 1.1 ml/L which corresponds to 2.75 ml/cycle and

2.4 pump. Other detergents may require change.

• The above chemical dose info in the table is only a guide.

• In the above table, the doses of “ml/L" and "ml/cycle" and their corresponding "pump revolutions and

on-times" are based on the respective manufacturer’s dosed recommendations (obtained from the rinse

aid's MSDS/ SDS or Technical Data Sheet) and the AM16 rinse water volume of 0.67 gal/cycle.

• For chemicals with known % dilution, calculate "ml/L" by multiplying the known % dilution by 10 e.g., 0.05

% to ml/L is 0.050 % * 10 = 0.50 ml/L.

• For chemicals not listed in the table and dose unknown, use the rinse aid dose of “0.9 ml/L which

corresponds to 2.25 ml/cycle" or work with the chemical vendor for a recommended dose.

• With the information on "ml/L", calculate "ml/cycle" by multiplying the known "ml/L" by 2.535 e.g., "0.50

ml/L" to "ml/cycle" is 0.50 ml/L* 2.535 = 1.27 ml/cycle.

• The factor "2.535 (i.e., 0.67 gal/cycle * 3.785 L/gal) " is based on the AM16 rinse volume of 0.67 gal/cycle

• The AM16 machine factory sanitizer default is set to 1.57 ml/L which corresponds to 3.8 ml/cycle and

80 ppm chlorine of 5.25 wt.% sodium hypochlorite in bleach solution at 11% pump speed.

• The above chemicals dose info in the table is only a guide.

• In the above table, the sanitizer doses of “ml/L" and "ml/cycle" and pump speed are based on the

respective wt.% of the sodium hypochlorite in bleach (obtained from the sanitizer's MSDS/ SDS or Technical

Data Sheet) and the AM16 machine's rinse water volume of 0.67 gal/cycle to form the minimum 50 ppm or

maximum 100 ppm of chlorine required of NSF sanitization.

• For chlorine-based sanitizers with names not listed in the table but has the same wt.% of the sodium

hypochlorite in bleach as in the table, the associated data could be used as a guide subject to conrmation

by testing on the machine using chlorine test strips.

• For chlorine-based sanitizers with names not listed in the table with unknown wt.% sodium hypochlorite

in the bleach, ensuring chlorine sanitization anywhere from 50 ppm to 100 ppm of chlorine inclusive for

sanitization should be done by testing on the machine.
