Why Is There Condensation Com-
ing From The Unit?
Condensation production is normal
for all devices that use refrigeration
principles. Air conditioners are a good
example of systems that produce water
condensation.
Condensation occurs when relatively
warm moist air passes through the
cold evaporator. Moisture contained in
the air condenses (deposits) onto the
evaporator ns, then runs down into
the drainage system located under the
evaporator. It is this water that you see
owing from the condensate drain of the
system.
The amount of condensation will vary
with the humidity of the location, so the
amount of condensate that ows from
the module will also vary.
When condensate is created, it runs
into the “Condensate Tray” which sits
on top of the storage tank. This then
runs out through the “Condensate
Drain” which is a feature of the tray.
A plastic drain pipe is attached to this
drain allowing easy access for the
plumber to attach the condensate drain
line away from the heater.
What Should I Do During Holi-
days?
If you are going to be away for a week
or more, it is advisable to turn off the
electricity supply to the system. While
there is no damage likely if the electricity
is left on, you will consume energy
through storage tank heat losses which
can be avoided.
Warning: If the hot water system is
not used for two weeks or more, a
quantity of hydrogen gas, which is highly
ammable, may accumulate in the water
heater. To dissipate this gas safely, it is
recommended that a hot tap be turned
on for several minutes at a sink, basin
or bath, but not a dishwasher, clothes
washer, or other appliance. During this
procedure, there must be no smoking,
open ame or any other electrical
appliance operating nearby. If hydrogen
is discharged through the tap, it will
probably make an unusual noise similar
to air escaping.
