Tempstar/HH GPX Series Technical Manual 7610-002-57-32
Issued: 07-24-2006 Revised: N/A
SECTION 2: INSTALLATION/OPERATION INSTRUCTIONS
OPERATION INSTRUCTIONS
12
PREPARATION: Before proceeding with the start-up of the unit, verify the following:
1. The pan strainer and pump suction strainer are in place and are clean.
2. The overflow tube and o-ring are installed.
3. That the wash and rinse arms are screwed securely into place and that their endcaps are tight. The wash and rinse arms
should rotate freely.
GAS BOOSTER HEATER OPERATION: For all start up and operation information, please refer to the manual supplied with
your gas booster heater.
POWER UP: To energize the unit, turn on the power at the service breaker. The voltage should have been previously verified
as being correct. If not, the voltage will have to be verified.
FILLING THE WASH TUB (TEMPSTAR GPX): Ensure that the delime switch is in the NORMAL position, and place the power
switch into the ON position. The Tempstar model should fill automatically and shut off when the appropriate level is reached
(just below the pan strainer). Verify that the drain stopper is preventing the wash tub water from leaking excessively. There may
be some slight leakage from the drain hole. Verify that there are no other leaks on the unit before proceeding any further. The
wash tub must be completely filled before operating the wash pump to prevent damage to the component. Once the wash tub
is filled, the unit is ready for operation.
FILLING THE WASH TUB (TEMPSTAR HH GPX): For the initial fill, ensure that the cycle selection switch is in the “AUTO”
(automatic) position, and place the power switch in the “ON” position. The unit will fill automatically and run through a rinse
cycle. Open the doors and verify that the water level is correct. Hereafter, the water level is controlled by the overflow tube.
Verify that the drain stopper is preventing the wash tub water from draining excessively. There may be some slight leakage from
the drain hole. Verify that there are no other leaks on the unit before proceeding any further. The wash tub must be complete-
ly filled before operating the wash pump to prevent damage to the component. Once the wash tub is filled, the unit is ready for
operation.
WARE PREPARATION: Proper preparation of ware will help ensure good results and less re-washes. If not done properly, ware
may not come out clean and the efficiency of the dishmachine will be reduced. It is important to remember that a dishmachine
is not a garbage disposal and that simply throwing unscraped dishes into the machine simply defeats the purpose altogether
of washing the ware. Scraps should be removed from ware prior to being loaded into a rack. Pre-rinsing and pre-soaking are
good ideas, especially for silverware and casserole dishes. Place cups and glasses upside down in racks so that they do not
hold water during the cycle. The dishmachine is meant not only to clean, but to sanitize as well, to destroy all of the bacteria
that could be harmful to human beings. In order to do this, ware must be properly prepared prior to being placed in the machine.
DAILY MACHINE PREPARATION: Refer to the section entitled “PREPARATION” at the top of this page and follow the instruc-
tions there. Afterwards, check that all of the chemical levels are correct and/or that there is plenty of detergent available for the
expected workload.
WARM-UP CYCLES: For a typical daily start-up, it may be necessary to run the machine through 3 cycles to ensure that all of
the cold water is out of the system and to verify that the unit is operating correctly. To cycle the machine, ensure that the power
is on and that the tub has filled to the correct level. Lift the doors and the cycle light will illuminate. When the light goes out,
close the doors, the unit will start, run through the cycle, and shut off automatically. Repeat this two more times. The unit should
now be ready to proceed with the washing of ware.
WASHING A RACK OF WARE: To wash a rack, open the doors completely (being careful for hot water that may drip from the
doors) and slide the rack into the unit. Close the doors and the unit will start automatically. Once the cycle is completed, open
the door (again watching for the dripping hot water) and remove the rack of clean ware. Replace with a rack of soiled ware and
close the doors. The process will then repeat itself.
