Hot Water Output Will
Not Maintain Control Too many or too few heaters on. Check graphs and table to determine
amount of heat necessary.
Temperature Control valve faulty. Clean and check or replace.
Emergency Corrective Action
Shut temperature control valve off by
depressing the button on the side of
the valve actuator housing and turn the
lever fully clockwise. Then use the
manual bypass valve to manually
control output temperature.
Large Flow In
Overboard Dump Line Leaking relief valve. Clean relief valve and reset. If valve
continues to leak, replace.
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.

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.
Faulty overload relay. Replace.
Inlet Pressure To
Pump Is Low Faulty pressure regulator. Replace.
