6 Troubleshooting/Problem Solving
NOTE: if the power for the water heater is
i
turned off and then back on, the compres-
sor will not start for 3 minutes to avoid in-
ternal damage.
Problem
Water heater is noisy.
Water heater is making the
room too cold.
Water dripping down the out-
side of the heater.

Cause
Fans are used to move air through
the system. The fan noise volume
will vary as the water is heated.
Room is not vented properly or is
too small.
Condensate drain hoses are not
connected.
Condensate drain hoses are
kinked or clogged.
Hot/Cold water connections are
not tightened.
Solutions
Some amount of fan noise is normal (sim-
ilar to the blower on a central heating
and cooling system). If you hear an
abnormal noise like a knocking or the
noise level seems unusually loud, please
contact service.
If noise level has been increasing over
the last weeks or months, the filter may
be getting dirty thus making the fan work
harder. Check to see if filter needs to be
cleaned. (See page 24 for instructions).
If the room is smaller than 10' x 10' x 7',
then a louvered door or other means to
allow air exchange with surrounding
rooms will be necessary.
Two drain hoses are included with your
water heater. Connect the longer 6' hose
to the lower condensate drain port. Con-
nect the short 3" hose to the upper con-
densate drain port.
Remove each drain hose and clear any
debris from the line. You can use a small
wire like a hanger or a small screwdriver
to clear out any debris in the drain port
the unit.
Tighten the inlet and outlet pipe connec-
tions.
