9. Check quick disconnects on face panel. Solution hose or tool may be faulty.
Intermittent or reoccurring pressure problems often indicate a disconnect
malfunction.
TROUBLESHOOTING GUIDE (continued..)
PULSATIONS IN PUMPING SYSTEM
Slight pulsations in the pumping system are normal due to the pulse pump putting a slight additional
load on one cylinder of the main pump however if pulsations are severe look for the following:
1. Chemical use very high. (over 5 gallons per hour)
2. Chemical system not bled properly or is letting air into pulse pump.
3. Air getting into pump inlet via:
a. Leaking inlet plumbing (bad hose washer, loose fittings, cut hose,
filter gasket etc.).
b. Worn inlet seals on pump.
4. Dirty or defective valve in pump or pulse pump.
5. Defective plunger(s) or worn high pressure seal.
6. Blockage or defective disconnect in down stream plumbing.
7. Insufficient water supply; pinched hose, blocked filter, empty water tank.
WATER TEMPERATURE LOW
The causes of low water temperature are usually easy to locate. Check the following:
1. The temperature control valve could be turned to the open position (an error) or it could be
defective. A defective valve will allow water to leak
through it causing low temperatures.
2. The coolant level in the radiator is low.
3. Radiator stop leak has been added to the system. This coats the preheater
coils and reduces the heat output. If this has occurred the preheater must be
removed and internally cleaned.
4. Defective engine thermostat.
5. Defective radiator cap.
