SECTION 5: SERVICE PROCEDURES

WASH TANK HEATER REPLACEMENT (CONTINUED)

14. Using the torque wrench or a torque nutdriver (if available)

torque the nuts holding the wires, jumpers and bus bars to 16

in-lbs.

15. Ensuring that all non-essential personnel are clear of the

area, place the drain stopper back in the wash tank and

restore power and water to the unit. Turn the unit on and allow

it to fill normally.

18. Verify that there are no leaks around the heater. If there

are, attempt to tighten it down (with power secured to the unit

at the service breaker to prevent injury) as the tank will change

shape slightly as it heats up.

19. Use the amp meter to take readings off of the power lines

to the heater, verifying the amperage draw to the machine

data plate.

20. Wait until the heater contactor kicks out (meaning that the

tub has reached the appropriate temperature) and allow the

machine to operate approximately ten minutes to verify that

there are no leaks and that the heater is maintaining the tank

temperature.

21. Replace the heater cover.

23. Replace the front door.

AFTER MAINTENANCE ACTIONS

Service personnel may want to drain the machine

and allow it to cool down. Secure power to the unit at the ser-

vice breaker and then verify the torque of all fasteners covered

in this instruction.
