4. Pump inoperative
a. Inspect pump and motor coupling for wear.
b. Clean any debris or liquid from connection area.
5.3 Motor Runs Hot
NOTE:
Under normal conditions, the temperature of the motor may operate up to 40C
(104F) above ambient (room) temperature.
1. Pump/motor binding.
a. Remove pump head and try restarting motor.
b. Inspect pump and motor coupling for wear.
c. Clean any debris or liquid from connection area.
d. See 5.4
e. Replace pump.

b. Check motor/pump coupling for alignment.
c. Confirm amperage draw with meter.
d. Motor insulation shorted, replace motor.
3. Voltage too low.
a. Check voltage against serial label and motor label, correct condition.
5.4 Low Pump Pressure
1. No pressure develops above level of feed pressure.
a. Verify motor operation and water line connections.
b. Verify flush valve is in the dialyze position.

d. Verify (lower than normal) flow from waste, if high check flush valve
operation.
e. Pump damaged or worn out, replace pump.
2. Pressure develops but does not achieve normal operating pressure.
A. Waste or product flow too high.
a. Check water temperature and flow rate.
b. Check quality of product water.
