WATER RECYCLE SYSTEM TROUBLESHOOTING --
STILL PRESSURE HI
When a STILL PRESSURE HI fault occurs there is good possibility that a boil over will occur.
Boil overs will cause steam loaded with anti--foam to be carried through the distillate plumbing
into the coalescing filter. This will result in the premature clogging of the coalescing filter.
Repeated STILL PRESSURE HI faults are an indication that the boiling rate in the still is too fast
due to high ambient temperatures. Staggering the laundry cycles so that one drum is washing
and rinsing while the other drum is drying will limit the amount of water in the still and greatly
reduce the likelihood of a boil over.
Observe the sight glass on the still.
Is boiling water or foam visible?
YES Add anti--foam with hand pump in 1/2 stoke increments as necessary to prevent the still from
boiling over if possible.
NO Go to step 2.
Observe operator panel A display (WP 0008 00, Figure 2, 6) for approximately 5 minutes.
After 5 minutes is STILL PRESSURE HI displayed?
YES Go to step 3.
NO Return to normal operation.
Observe operation of condenser fan.
Is condenser fan on?
YES Notify maintenance.
NO Go 20 HP INVERTER FAULT.
20 HP INVERTER FAULT
Use MENU SELECTION switch (WP 0008 00, Figure 2, 7) to select PAUSE at both operator panels.
Position CONTROL POWER switch (Figure 1, 3) to OFF and then back to ON.
Position MAIN POWER switch (1) to OFF.
Wait about 20 seconds, then position MAIN POWER switch to ON.
Position CONTROL POWER switch (3) to ON.
At inverter enclosure press 20 HP RESET switch (Figure 3, 4).
Wait about 20 seconds, then observe operator panel A display (Figure 2, 6).
Does 20 HP INVERTER FAULT message disappear?
YES Go to step 8.
NO Notify Maintenance.
At operator panel A use MENU SELECTION switch (7) to select PRESS TO START.
When FILL TANKS option is displayed select OVERRIDE FILLING.
10. When HEAT WATER option is displayed listen for condenser fan to come on.
Does condenser fan come on?
YES Go to step 11.
NO Go to step 12.
