CONTAINERIZED KITCHEN (CK)
UNIT MAINTENANCE PROCEDURES
TEST
Pump Assembly: Run faucet water into the sink. The pump should run periodically. Check
the pump assembly by temporarily connecting the pump assembly power cord to the Appliance
Control Box and check for 115 VAC at the pressure switch. Disconnect the power cord from the
appliance control box. Replace the pump if necessary.
Water Heater: The water heater can be tested by removing the access cover at the side of the
tank. Temporarily connect the water heater power cord to the appliance control box and check
for 115 VAC between terminals 1 and 3 (refer to wiring diagram on side of water heater).
Depress the reset button and recheck voltages. If the 115 VAC is present the water heater
should be replaced following the procedure in the next section. If the 115 VAC is not present,
check the power cord and refer to WP 0018 to check power distribution. Disconnect the power
cord from the appliance control box.
Casters: Disconnect the power cords from the Appliance Control Box. Attempt moving the sink
assembly with the casters unlocked. It should move freely without binding of the casters. Move
the sink in all directions to isolate the problem to a particular caster. Check for foreign material
in the caster flanges. Refer to the procedure in the following section to replace a caster.
REPLACE
Caster: The sink assembly contains locking casters in the front of the assembly and non-
locking casters in the back. Locking casters may be used as replacements for non-locking
casters with the caster left in the unlocked position. See Figure 1. To replace a caster (front or
back) remove the four screws from the mounting plate and the damaged caster. Replace the
caster and reinstall the four screws.
