Installation, Operation and Care Of
AM SELECT DISHWASHERS
SAVE THESE INSTRUCTIONS
GENERAL
ModelsAM15,AM15VL,AM15T,andAM15VLTdishwasherscanbecongured
for both straight through or corner operation. Models AM15F and AM15VLF are
conguredforfrontloading.AM15,AM15VL,AM15T,andAM15VLTdishwashers
are shipped from the  factory in straight-through conguration. Straight-through
machines can easily be converted to corner operation. Models AM15F and AM15VLF
include a front-loader shelf and left- and right-side shields as standard equipment.
The front-loader shelf on the AM15F and AM15VLF can be positioned up (inside
themachineduringoperation)ordown(outsidethemachineduringoperation).
The AM15, AM15F and AM15T dishwashers are designed to operate in one of two
modes: Hot water sanitizing mode (designated by the letters “AH” or “AP” on the
displaywhenthemachineisturnedon),orachemicalsanitizingmode(designatedby
the letters“AC”onthedisplaywhenthemachineisturnedon).AM15VL,AM15VLF
and AM15VLT dishwashers are designed to operate in hot water sanitizing mode
only(designatedbytheletters“HL”onthedisplaywhenthemachineisturnedon).
The serial number can be found on the machine data plate located on the bottom of
the front panel. The pump motor is rated 2 H.P. and has thermal overload protection.
DO NOT attempt to operate this dishwasher in the chemical sanitizing mode without
aproperlyinstalled,NSFCertied,chemicalsanitizerfeeder(customersupplied).
Contact an authorized detergent representative for information about a chemical
sanitizer feeder.

located in the wash tank, shuts off the heat supply if the water level becomes too low.
When the water returns to the proper level, the heating circuit is again operational.
A frame-mounted 8.5 kW electric booster water heater is available as an option
for models equipped with electric tank heat. The booster water heater is standard
for"VL"models.FormodelsAM15,AM15F,andAM15Ttheboosterwaterheater

AM15VLF, and AM15VLT, the booster water heater is designed to maintain a minimum
nalrinsetemperatureof180°Fwithcoldincomingwater.
Ventless models AM15VL, AM15VLF, and AM15VLT 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 AM15, AM15F and
AM15T models or gas heat dishwashers 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 and 11 for venting and
hoodrequirements.Verifywithlocalcodesfornalauthority.

WATER REQUIREMENTS
Proper water quality can improve warewashing performance by reducing spotting,
lowering chemical supply costs, improving productivity and extending equipment
life. Local 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specicspriortoinstallation.
Recommended water hardness is 3 grains of hardness per gallon or less. Chlorides
must not exceed 30 parts per million. Water hardness above 3 grains per gallon
shouldbetreatedbyawaterconditioner(watersoftenerorin-linetreatment).Water
treatment has been shown to reduce costs associated with machine cleaning,
reduce the need for deliming the dishwasher and reduce detergent usage.
Sediment, silica, chlorides or other dissolved solids may lead to a recommendation
forparticulateltrationorreverseosmosistreatment.
If an inspection of the dishwasher or booster heater reveals lime build-up after the
equipment has been in service, in-line water treatment should be considered, and,
if recommended, should be installed and used as directed. Contact your Hobart
Serviceofceforspecicrecommendations.

A small amount of water will likely dribble out of the lower rinse arm into the tank
between cycles due to the natural expansion of water as it is being heated.
With Electric Booster Water Heater - Models AM15VL, AM15VLF, and AM15VLT
Ventless models require both a cold water supply connection and a hot water supply
connection. The cold water supply line is connected to the line strainer at the top of
the machine with a 1⁄2 inch pipe. A pressure regulator and pressure gauge are not
required.Amanualshut-offvalveandpipeunionarerequired(customersupplied).
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 inch pipe for the 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 room after the condensing cycle is complete,
contact Hobart Service to increase condensing time.
The hot water supply line is connected to the line strainer at the rear of the machine
with a 1⁄2 inch pipe. A pressure regulator and pressure gauge are not required as
this is a pumped rinse machine. A manual shut-off valve and pipe union are required
(customersupplied).

GAS TANK HEAT (WHEN SPECIFIED)
Check the gas data plate attached to the dishwasher or the tag attached to the
incominggaspipingforthetypeofgastobeused.Theburnerisnotadjustable.
ThemaximumowinginletgaspressuremustnotexceedtheMaximumvaluein
the table. If line pressure exceeds the Maximum value in the table, an additional
pressureregulator(notsupplied)mustbeinstalledinthesupplyline.
Static inlet line pressure should not exceed 14 inches W.C. The minimum value
isforinputadjustment.
The gas valve is provided with a pressure tap to measure the gas pressure downstream,
which is also the manifold pressure. Gas supply piping must have a sediment trap
(suppliedbyothers)installedaheadofthedishwasher’sgascontrol.Connectthegas
supplytothe1⁄2inchNPTgasinletunderneaththemachine(Fig.11).
Do not use Teon tape on gas line pipe threads. For gas line
pipe connections, use Loctite 565, Hobart part 546292, or a exible sealant
suitable for use with Natural and Propane Gases.
The appliance and its gas connections must be leak tested before placing the
appliance in operation. Use soapy water for leak test. Do notuseopename.
The installation must conform with local codes, or in the absence of local codes,
withtheNationalFuelGasCode,ANSIZ223.1(latestedition).Copiesmaybe
obtained from American Gas Association, Inc., 1515 Wilson Boulevard, Arlington,
VA 22209.
The appliance and its individual shutoff valve must be disconnected from the gas
supply piping system during any pressure testing of that system at test pressures
in excess of 1⁄2psig(3.45kPa).
The appliance must be isolated from the gas supply piping system by closing
its individual manual shutoff valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than 1⁄2psig(3.45kPa).Dissipate

arenotprovidedwithauecollarandarenotintendedtohavetheuedirectly
connected to a ventilation system. However, the products of combustion must be
vented to the outside air. The most common method of venting is a vent hood over
theentiredishwasher(Fig.12).RefertoRateofExhaustFlowCalculationsonthe
next page for calculations of the proper vent rate for your hood. Another method
isasmallventhood(Fig.13)positionedaboutveinchesabovetheueexitat
the rear of the dishwasher and connected to existing ductwork. In either case,
anelectricalinterlockmustbeinstalledtoallowtheowofgastothedishwasher
burner ONLY when the exhaust system is energized. For additional information,
refer to the National Fuel Gas Code, ANSI Z223.1, NFPA 54.
Make sure the installation meets the local code for your area.

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 2009 International Mechanical Code.
TheminimumnetairowforTypeIIhoodsusedfordishwashingappliancesshall
