Unit installation

SPRINKLER LOCATION
Relocate or remove any sprinkler heads that have the
chance of spraying on or into the unit.
Make sure there
are absolutely no sprinkler heads near the heater that
will in any way spray on or into the heater. Sprinkler
damage is not covered under the warranty agree-
ment. Make sure they are a sufficient distance away so
normal wind currents will not carry the mist to the heater.
The heater is designed to handle the wettest weather
conditions that are typical of rain and humidity, etc.
However, sprinkler heads force high pressure water into
the unit from the side at an odd angle. Most sprinkler
systems are connected to a well system. Most well water
is high in minerals, sulphur and other aggressive con-
taminates. These contaminates will leave a build up on
the evaporator coils and electronics causing corrosion
and hamper the efficiency. If you are located within 15
miles of the coast, salt may be in the well water also.

CLEANING
To clean the heater you should take a sponge and mild
soapy water and wipe the surfaces clean. Do not use a
pressurized garden hose to clean the heater. Never force
water into the unit from any direction. You may use a
garden hose at low pressure with no nozzle attachment
to rinse the air coils. Pour a mild liquid soap into the
water stream as you rinse the air coils. Clean the evapo-
rator air coils at least 4 times a year. If you live near the
sea coast, you will need to clean at least 6 times a year
or more to remove salt and sand. Clogged evaporator
coils will reduce the efficiency of the unit and cause
corrosion. A professional should clean the coils peri-
odically, every year or two.
ROOF CLEARANCE & RUN OFF
Be aware of roof slope and overhang above the heater.
Sharp sloping roofs without gutters will allow massive
amounts of rain water, mixed with debris from the roof
to be forced through the unit. Roof valleys that collect
run off from two slopes are especially important to avoid.
If space is limited, determine if a gutter or down spout
is needed to protect the heater. Low roof overhangs may
obstruct the air flow out of the unit and require 48 inches
of clearance, See diagram below.

CAUTION
Chemicals should NOT be stored near the heater. The
fan may draw corrosive chemical vapor through the unit
causing damage. Do NOT store anything on top, under-
neath or around the heater. You will need access to the
disconnect breakers in the event of an emergency.
