E. Prime Fuel Supply and Heat Water Tanks
1. Slide air inlet filter (1) out of heater (2).
When priming fuel supply, reading at pressure gauge (7) must be at ZERO. If
pressure at this gauge increases when the PRIME PUMP switch in on, STOP the
priming operation and notify Unit manintenance. Attempting to start the heater with
excess fuel in the combustion chamber can cause an explosion and injury to
2. Prime fuel supply to heater (2) as follows:
a. Lift and hold PRIME PUMP switch (3).
b. Observe reading on pressure gauge (4).
c. Release switch (3) when pressure gauge (4) remains steady at 135 psi or higher for a continuous 120
3. Slide air inlet filter (1) back into heater (2) with direction arrow (5) pointing towards heater inlet.
If the water heating operation is stopped while in progress, OVERRIDE FILLING
should be selected when system is restarted. Selecting the FILL TANKS option will
result in excess water being added to the rinse 2 tank.
4. Press appropriate MENU SELECTION switch as follows:
a. Select MODIFY SETPOINT to change displayed setpoint in 5 degree increments until desired setpoint is
b. Select HEAT WATER to heat water in tanks. Proceed to step 5.
c. Select OVERRIDE HEATING to bypass water heating. Proceed to DAILY OPERATING PROCEDURES,
step B (WP 0010 00) to load laundry.
5. Monitor display, it should read:
SETPNT= XXX F TEMP = XXX F
6. Observe heater (2) operation as follows:
While priming heater fuel system, blower may turn on and off. PRIME PUMP switch
may be released when blower is not operating and pushed when blower starts.
If correct fuel pressure can not be obtained within five priming attempts, notify
a. Wait for blower (6) to come on.
b. Lift and hold PRIME PUMP switch (3) while monitoring pressure gauge (7).
c. With blower (6) operating, observe fuel pressure at gauge (7). If above 125 PSI, release PRIME PUMP
d. Observe fuel pressure gauge (7). If pressure remains above 125 PSI proceed to step 7, otherwise repeat
steps a through c.
