Installation, Operation and Care Of

AM16X DISHWASHERS

SAVE THESE INSTRUCTIONS

GENERAL

All AM16X models are shipped from the factory for a straight through conguration and can

be easily converted to a corner operation.

The AM16-BASX, AM16T-BASX, AM16VL-BASX and AM16VLT-BASX 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 controls on the lower part of the machine.

The AM16SCBX and AM16VLSCBX 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 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 corner of the machine.

Hobart supplied chemical pumps ship standard with all AM16SCBX and AM16VLSCBX

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-BASX

and AM16VLT-BASX, 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 AM16SCBX and AM16VLSCBX 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-BASX, AM16VLT-BASX, and AM16VLSCBX 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-BASX and AM16T-BASX

models typically require a hood or vent 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 10

- 11 for venting and hood requirements. Verify with local code ofcials for nal determination.

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

Installation must be in accordance with state and local codes and the National Electrical

Code ANSI/NFPA70 (latest edition). In Canada, the installation code is CSA 22.1 (latest

edition).

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 20" clearance at the right

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.

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 your 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:

WATER SUPPLY REQUIREMENTS

– 9 –

AM16VLSCBX models require both a cold water supply and a hot water supply.

On AM16VL-BASX, AM16VLT-BASX and AM16VLSCBX 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 be 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.

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 AM16X 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.

For -BASX and VL-BASX models, pumped drain air gap kit is available through sales using

accessory code PUMPDRN-AIRGAP or service kit part # 00-562492.

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-BASX, AM16VLT-BASX and AM16VLSCBX 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

11) for heat dissipation or heat gain to space.

insulated wire for the connections. Do not use bell wire, lamp cord or similar type wire. Splice

connections, if required, must be made in the feeder transformer junction box (supplied by

others) — not in the main controls enclosure. Use 7/8" diameter hole located at right rear

corner of machine for 1/2" trade size conduit tting. Strain relief ttings must be provided

for all wiring.

If machine is not equipped with Hobart built-in chemical pumps, an automatic detergent

dispenser is required. Closely follow supplier’s instructions.

Close the door. Press the POWER button to turn the power on (Fig. 20). If the machine’s

door is closed and no water is in the tank, the ll cycle will begin automatically. If water is

detected in the tank, the machine will drain the water out prior to lling with fresh water.

During the ll cycle, the word FILL is displayed along with an image of a faucet. Throughout

the ll cycle, the machine will toggle between the ll mode and a preheating mode. During

the preheating mode, WARM UP is displayed along with an image of a thermometer.

NOTE: On machines equipped with the energy recovery feature, it may take up to 20

minutes to complete the ll process.

DISHWASHING

Scrape the dishes to remove large particles of food and debris. Never use steel wool on

ware to be loaded into the dishmachine.

Arrange the dishes in a rack. Do not stack dishes one on top of another, as water must

have free access to all sides of every dish. Stand plates and dishes up edgewise in a

peg-type rack (Fig. 21). Cups, glasses and bowls should be inverted in an open-type or

compartment-type rack (Fig. 21). Silverware and other small pieces may be scattered

loosely over the bottom of a at bottom rack.

Do not allow foreign objects to enter the unit, especially metallic contaminants.

Select the wash cycle: 1 for normal serving ware, 2, 4 or 6 for pots and pans.

After lling a rack, open the door, slide rack into the dishwasher and close the door.

Throughout the wash cycle, the tank water temperature is displayed along with the word

WASH. During the rinse cycle, the rinse water temperature is displayed, along with the word

RINSE and an icon. When the rinse cycle is completed, the readout displays READY and

the tank water temperature.

For ventless models, the door must remain closed until the condensing cycle is complete. All

ventless models include a lock to prevent the door from opening until the cycle is complete.

A condensing progress indicator is displayed during the condensing cycle. Failure to follow

these instructions will result in excess steam and water vapor in the dish room.

When the display reads READY, open the door, remove the clean dishes, slide in another

rack and close the door.

This dish machine is not meant to be opened until a cycle has completed, but if a dish must

be added after the wash cycle has started, open the door slowly, until the pump stops.

Wait 10 seconds to allow the wash arm to coast down and to avoid water splashing before

opening the door fully.

Operating temperatures for all models are as follows:

For "VL" models only – If excessive amounts of steam or water vapor exit the

machine after cycle is complete and door is opened, incoming cold water temperature

may be too high. Contact Hobart Service to adjust the rinse and condense

times according to the adjustment table shown below. Increasing cycle time will

increase water consumption and decrease the racks per hour, but should reduce

the steam and water vapor entering the dish room.
