AM60E dishwashers can fill automatically and two kind of wash time can be
selected. When doors of AM60E dishwashers are opened, machines are stopped
immediately. When water level of tanks is normal, open the door to push the rack
in, then closed the door，an automatic wash and rinse cycles begins. If machines
are short of water，close the door，machines can fill automatically. When water
level is normal, an automatic wash and rinse cycle begins.
Electrical booster heat options (6KW and 12KW, please explain clearly before
order) include a sealed booster or an open booster tank. In Addition, Dish table
heights may be specified at time of order for 800mm (31.5 inches) or 860mm
(33.875 inches).

INSTALLATIONS
Unpacking
Immediately after unpacking, check for possible shipping damage. If the
dishwasher is found to be damaged, save the package materials and contact the
carrier within 15 days of delivery. Please take out parts of scene installation
(overflow pipe, vent cover), manuals and maintenance card. Please fill out
necessary information carefully.
Before installation, check the electrical service to be sure it agrees with the
electrical specifications on the data plate located on the right side of machines.
Circuit diagram located backside of panel-front.
Location
Place the dishwasher in its operating location. Turn the leveling feet as required
to level the machine and adjust to the desired height. Before finalizing the
location, make sure that consideration has been given for the electrical conduit,
water supply, drain connection, gas booster location (if applicable),tabling,
chemical feeder replenishment(if applicable),daily cleaning, maintenance and
adequate clearance for opening the doors(Fig.1)

Dish table should be turned down and fitted into the dishwasher (Fig.2). Use a
suitable sealer between table and tank lip to prevent leakage.
A hood or vent may be required in order to meet local codes. The ventilation
volume should be
more than 2.8m3/min
in case of using hood

WARNING：Electrical and grounding connections must comply with applicable
portions of the national electrical code and/or other local codes.
WARNING: A fused disconnects or circuit breaker with electrical leaking
protector (not supplied) must be installed in the electrical line supplying the
dishwasher and should meet the requirements of your local electrical code.
WARNING: Disconnect the electrical power supply and place a tag at the
disconnect switch indicating that you are working on the circuit.
Power supply (If power cable is not supplied with machine)
Remove the side panel.
Let the power cable thread the wiring hole on the bear panel. And fix the cable
via the cable clip.
Page 10

Let the cable thread the cable bushing, and strip the cable if necessary.
Connect the power cable to terminals on the control board according to the
picture.
Please install leakage protection switch. The horizontal distance between power
switch and one side of machine is about 0.5m. The height of power switch is
about 1.7m. Five-line cable is prepared for AM60E dishwashers. Refer to the
electrical diagram on the side of side panel. Connect the electrical supply wires
with different colors to terminal block(Fig.4).

Plumbing Connections
Water supply
Warning: Plumbing connections must comply with applicable sanitary,
safety and plumbing codes.
Please install 3/4” valve in the range of 1m to machines. Connect the Water pipe
to the incoming water supply (3/4”).The water supplied hardness should be ≤
0.5mmol/L. If hardness exceed limit, please increase softening system to make
sure machine can operate normally.
Note: The water hardness should be ≤0.5mmol/L. If not, water softener is
strongly recommended. Or else, may affect the warranty set out in the
standard condition of sale.
Note: In case of line dynamic pressure less than 0.098MPa on sealed booster
machine; or line dynamic pressure less than 0.049MPa on open booster
machine，a pressure-pump must be installed (by others); in case of line
static pressure more than 0.784MPa，a pressure reducer must be installed
(by others).

Drain
Connect the 11/4” NPT drain connector under the wash tank to a suitable drain. If
a grease trap is required by code, it should have a minimum flow capacity of 95.5
liters per minute (21 gallons per minute).
Power supply for detergent dispenser and/or rinse sanitizer feeder
(by others)
Terminals DSP1 and DSP2 in the control box allow connection of detergent
dispenser (by others). RPS1 and RPS2 terminal allow connections of a rinse
sanitizer feeder (by others) with maximum current of 3 Amps (Fig.4).
DSP1-DSP2 is powered during the wash cycle. RPS1-RPS2 is powered during
the rinse cycle. Refer to the electrical diagram on the side of side panel.
Fig.4
Notes: The move of control box must be considered during wire connection and
provide extrusions of wire.
Notes: Please use insulated jacket wire above 600 Volts and do not use wire of
light and electric ring.

MAINTENANCE
Warning: Disconnect electrical power supply and place a tag at the disconnect
switch indicating that the circuit is being worked on before any maintenance
procedure.
Wash arms
Upper and lower wash/rinse arms should turn freely and continue turning for a
while after being whirled by hand. To check arms, DISCONNECT ELECTRICAL
POWER SUPPLY, rotate arms, and remove any obstructions causing improper
operation.
If the strainer pans or pump intake screen is not properly in place, obstructions
(such as food particles or bones) may clog the wash arm nozzles. The wash
arms are easily removed for cleaning.
WARNING: There may be hot water in the wash/rinse arms, please wait at least
5 minutes after turning off the machine before removing the wash arms.
To remove the arms, unscrew the knurled disk on the arms and take them out.
Upper and lower arms are interchangeable.
