Troubleshooting
Large flow in overboard
dump line.
Manual bypass valve left open.
Close valve.
Too many heaters on for load on
system.
Refer to table to determine proper
number of heaters on or shut one
heater off and monitor temperature.
System will not run, fault
light is on.
No water is coming to system.
Float switch shut off.
Supply water to system and purge.
Make sure that water is flowing out of
system through umbilical hose.
Faulty float switch.
Repair or replace float switch.
Overheated water in the heater
tank.
Make sure that water is flowing
through the system.
No water in heater tank.
Re-prime system, making sure that
water is flowing through system.
Over temperature control needs
adjustment.
Readjust over temperature controls,
whichever one is turning the system
off if temperature of water is low.
Fault over temperature switch.
Determine which over temperature
switch is open circuited and replace.
The over temperature switches in
system are TC 1/1 and TC 1/2.
System will not run, pump
overload fault light on.
Pump overload relay has tripped.
Possible low voltage, single phase of
incorrect frequency. Check the input
voltage and frequency. Measure the
current on the pump motor to see if it’s
within rating. Reset overload and start
system again.
Faulty fault indicator relay, R1/R2. Replace.
Fault overload relay.
Replace.
Inlet pressure to pump is
low.
Faulty pressure regulator.
Replace.
Low pressure to system, below
3.5 bar.
Increase pressure and flow rate to the
system.
Pump varies in speed.
Belts slipping.
Check tension on belts. If tension is
loose, tighten belt by adjusting tension
bolts on motor mount.
Check belts condition. If belts are torn,
ragged, or in poor condition, replace.
Water temperature will
not rise adequately.
Insufficient number of heaters on
for load.
Turn on one additional heater. Check
Heater Selection
