“Heater 3 –
Over Temp”
Caused by the heater internal
temperature switch (X7) opening. Heater
#1 thermostat detected a temperature
higher than the set value on the dial.
1. Remove the cover on the Heater
and check the dial set on Heater #1.
2. Check K1T timer relay is set to the
proper settings.
1. Set the thermostat to ~210
°
F.
2. Replace thermostat.
3. Set the K1T relay is set to .2, 1, R. Cycle
power on the system to implement the
setting.
“Loop Alarm:
High Pressure”
1. Triggered by the loop high pressure
switch (X12).
1. Loop manifold valve not in correct
position.
2. Loop PRV set too high or failed.
3. Check Pressure switch Din
connector for loose or broken wires.
4. Check pressure on tank return
Pressure regulating valve is ~75 PSI
while loop discharge valve is closed.
1. Check valve position.
2. Check Loop PRV setting is ~25 psi while
RO is running.
3. Check Event log for other alarms.
4. Remove Din connector from pressure
switch and check for damage or broken
wires inside the connector.
5. Using the adjustment screw (under Din
connector or under sleeve) adjust the
pressure until the alarm clears.
6. Replace Pressure Switch.
“Loop Alarm:
Excess
Temperature”
1. Caused by the loop or tank
temperature sensors exceeding preset
MAXIMUM OPERATING TEMPERATURE
settings.
1. Faulty Tank/Return temperature
transmitter/s.
2. Faulty heater/s thermostats.
3. Incoming feedwater temperature
greater than preset max limit.
4. Check that set-point is at the
default value (Section 6.10) and the
Sanitization temperature is less than
that default.
1. Check transmitters.
2. Check all heater thermostats.
3. Verify that Heaters switch on and off.
3. Adjust sanitization temp to be less than
the maximum operating temperature
value.
“Excess water
loss during
hold period”
1. Caused by exceeding water loss volume
preset in Factory defaults (max 3 US Gals)
during heat up and hold phases of
disinfection cycle.
1. System/unit leak.
2. Loop outlet open.
3. Dialysis m/c drawing too much
water.
4. Faulty pressure transducer in tank.
1. Monitor for leaks.
2. Check all spare outlets are closed
during Heatsan cycle.
3. Check disinfect timings on dialysis
machines.
4. Verify the tank level shown on the
screen is accurate.
5. Remove Din connector from pressure
transducer and look for signs of
corrosion.
