The installation, and initial start-up of your dishwasher must be performed by qualied
electricians, plumbers, and authorized service technicians trained in commercial dishwashers.
Defects and repairs caused by unauthorized installers will not be covered by the dishwasher
warranty.
The HRU heats cold water supplied to the dishwasher's built-in heat exchanger which
raises the incoming temperature to approximately 110°F/43°C. The preheated water is
plumbed to the nal rinse water booster which ensures a minimum nal rinse water
temperature of 180°F/82°C to sanitize the clean wares. The HRU signicantly reduces
the energy required to heat water for the nal rinse operations.

Installation
1. Ensure that all utility connections are complete.
2. Remove the lower front panel of the unload section.
3. Remove the coil assembly (A) from the multi-rinse valve.
CAUTION:
to prevent damage to the valve coil, energize the multi-rinse valve for as short a
period as needed to make necessary PRV adjustments.
Immediately reinstall the coil assembly when PRV adjustments have been completed.
4. Turn on main water supplies to the dishwasher. Make sure steam supply is OFF.
5. Close all of the drain valves.
6. Remove the main control cabinet cover and set the Auto/Manual switch to the Manual position.
7. Turn ON main breaker power to dishwasher.
8. Turn OFF main breaker power to the booster and optional blower dryer (if equipped).
9. Turn dishwasher main power switch ON.
10. Allow dishwasher tanks to completely ll with water.
11. When dishwasher tanks are full, turn dishwasher main power switch OFF.
12. Turn the Auxiliary wash tank drain handle open and drain the tank (leave the drain open).
(This places the dishwasher in a FILL mode because the tank is empty.)
13. Turn the dishwasher main power switch ON.
14. The Green FILL light in the control cabinet will be ON when the machine is lling.
15. While the machine is lling, adjust the HOT PRV #1 until the nal rinse pressure gauge indicates
20 PSI. Tighten the PRV adjustment lock-nut to hold the setting.
16. Close the drain and allow the dishwasher to ll with water.
17. Turn the dishwasher main power switch OFF.
18. Make sure the main breaker or steam supply to the booster is OFF.
Turn the hot water off.
19. Turn the dishwasher control panel Power Switch on.
20. Press the ENERGY SAVER mode selector switch on the main control cabinet.
The green LED will illuminate and the conveyor will run.
21. While the machine is running, adjust the COLD PRV #2 until the nal rinse pressure gauge indicates 20
PSI. Tighten the PRV adjustment lock-nut to hold the setting.
22. Now set the cold water PRV #2 by adjusting the PRV until the nal rinse pressure gauge indicates 20 PSI
ow pressure. Note that the pressure gauge will cycle on for 15 seconds and then off for 30; therefore, the
pressure gauge will read a owing pressure for 15 secs., then read the no pressure for 30 seconds.
23. The Green FINAL light will be ON when the Cold water valve is ON. The Green REHEAT light will be ON
when the Hot water valve is ON.
24. To complete the settings: Turn the dishwasher main power switch OFF.
25. Turn the main breaker or steam supply to the booster on.

set-up procedures. Refer to the set-up procedures on the
previous two pages to set the pressure reducing valves.
In addition, the green lights will indicate the operation of the
booster valves during normal operation. Refer to
the simplied logic diagram below which shows the
interaction of the timers, thermistor reader (temperature
control module) and the booster solenoid valves.
Exhaust Blowers
