Install Manual

DHW plumbing consists of a closed recirculating loop which is purged free of air by the
installing dealer. If any maintenance or hot water tank replacement is done, ensure the DHW
plumbing is properly purged of air . Consult with your installing dealer before draining the hot
water tank for proper procedures.
During your annual preventative maintenance check, inspect the drain pans for debris to avoid
condensate tubing blockage. Tubing needs to be checked at both ends to ensure blockage does
not clog the pipe from the inside or outside of the house if exposed. In areas where algae
produce a slime in the drain pan, it may be necessary to chemically treat the problem.
Geocool units are equipped with controllers that allow for a system lock out feature. If the
system trips a protective limit switch 1 to 3 consecutive times, depending on what type of limit
switch, the system will lockout. If the system locks out, power will need to be cycled to reset the
lockout. Before resetting the lockout you must always ensure the problem causing the
lockout has been repaired . If unsure consult your installing dealer before resetting the lockout.
Be aware of all breaker locations.
Be aware of thermostat setting. In some cases, programmable thermostats will mistakenly
be programmed to set the temperature back when not desired. Check the programming to
ensure the correct time of day and desired temperature is programmed or set the thermostat on
hold . Which will stop the programming and allow a constant setting to be maintained.
ADDITIONAL REMINDERS: Chemicals, cleaners, inhibitors or other products that corrode or
attack copper (such as Trisodium Phosphate) should never be placed into the water circulation
loop(s) connected to the Geocool equipment or stored in the same room as the Geocool
equipment. Failure to follow this requirement will void the equipment warranty . Protect the
Geocool unit from freezing temperatures. If the system is in your attic or outside special
precautions may need to be taken to ensure the unit and associated piping does not freeze.
The Geocool unit should never be exposed to a dirty or dusty air environment. Dust, such as
sawdust or sheet rock dust, can damage the electrical components, fan motor, and air coil on
the unit. Simply place a cover (tarp, etc.) over the unit when construction or any other dust
producing job is being done in the area of the Geocool unit. Never run the system during
construction. Not only will sheetrock dust plug up and cause damage to the air coil but it will
also accumulate in the duct system and slowly be blown out over many years.
If the unit is ever moved from its original location, never lay it on its side. Never jar or drop the
unit during transport. This is a sealed refrigeration system; rough handling may cause the
system to develop a leak.
•Once removed, protect the system from freezing. Antifreeze may need to be flushed into the
plumbing. When being reinstalled, antifreeze levels will need to be checked. All plumbing from
the Geocool system to the hot water tank may require a licensed plumber.
Keep an accurate service record. Keep a copy of all service reports with this booklet.
