ALARM POSSIBLE CAUSES CHECKS & CORRECTIONS
Input voltage out of range
• A qualified person should be sure that the
average applied voltage is within ±10% of the
nameplate value and that the individual phase
voltages are within ±1% of the average voltage
(See NEMA MG-1).
• Note that the input voltage can go below
nominal ±10% at the moment of compressor
startup. A qualified person should measure the
input voltage at the moment of compressor
startup.
Input voltage phase rotation
reversed
• A qualified person should interchange any
two wires of the branch circuit. Do not move
any factory-installed wires.
One or more phases of the input
voltage are missing
• A qualified person should determine that all
phases are present. Check fuses and/or circuit
breakers.
For 460 V units, there is a crack
in the socket of the voltage moni-
tor
• A qualified person should inspect the socket.
Replace as necessary.
Defective voltage monitor
• Consult Dectron or a Dectron-certified
technician.
POWER FAILURE
The voltage monitor
circuit is open.
Pool water flow rate too high
• Be sure the pool water flow rate is as
specified.
Pool water temperature sensors
not calibrated
• Consult Dectron or a Dectron-certified
technician.
Loss of refrigeration capacity
• Be sure the refrigerant sight glass is full.
There should be neither bubbles nor droplets.
Pool heating diverting valve not
functioning
• Consult Dectron or a Dectron-certified
technician.
POOL 1 PERFOR-
MANCE ALARM

ature difference is less
than 8°F after 5 minutes
of heating.
