Owner Manual

YOUR GEOCOOL WATER SOURCE HEAT PUMP HAS BEEN BUILT TO BE AS
MAINTENANCE FREE AS POSSIBLE. THERE ARE ONLY A FEW THINGS YOU NEED TO
DO TO KEEP YOUR SYSTEM RUNNING AS EFFICIENTLY AS POSSIBLE.
IT’S STRONGLY RECOMMENDED TO HAVE THE UNIT CHECKED ONCE A YEAR BY A
TRAINED SERVICE PROFESSIONAL. MANY INSTALLING DEALERS OFFER
PREVENTATIVE MAINTENANCE CHECKS.
WARNING! BEFORE PERFORMING SERVICE OR MAINTENANCE ON SYSTEM, TURN
OFF ALL BREAKERS. ELECTRICAL SHOCK CAN CAUSE PERSONAL INJURY OR
DEATH.
• Keep a clean air filter on your unit. Air filters need to be changed about once every 30 days or
sooner, depending on the application. Always buy a good quality air filter. If filter is not changed
on a regular basis, expensive air coil cleaning may be required during preventative maintenance
checks.
• Give the unit an occasional visual check. Look for water around the base of the unit and listen
for any unusual noises
• Closed loop systems
IMPORTANT NOTICE: UNITS THAT UTILIZE GROUND LOOPS MUST MAINTAIN A
MINIMUM OF 20% METHANOL OR 25% PROPYLENE GLYCOL AS AN ANTIFREEZE
SOLUTION IN THE UNIT AND GROUND LOOP AT ALL TIMES. FAILURE TO DO SO WILL
ALLOW REFRIGERANT TEMPERATURES TO DROP, CAUSING INTERNAL FREEZING OF
THE UNIT TO OCCUR, CAUSING SEVERE DAMAGE TO THE UNIT. DAMAGE TO THE
UNIT CAUSED BY FAILURE TO MAINTAIN PROPER ANTIFREEZE LEVELS IS NOT
COVERED UNDER WARRANTY.
• Open loop systems require well water to be pumped through the unit. In this application
Geocool recommends the use of an isolation valve on the entering water line feeding water to
the Geocool unit. It is recommended that in open loop systems the electronic water control valve
be placed in the discharge line to prevent loss of pressure during off cycles.
Be aware of all isolation valves so cleaning can be done with minimal water spillage. It’s a good
idea to be familiar with the location of the isolation valves in the event of a major water leak. All
open loop systems have a discharge water line that discharges the water to a discharge well,
creek, pond, etc. Check local state and county codes for proper discharge of water. Be aware of
discharge location and check occasionally to insure proper drainage is occurring. During the
winter, insure discharge is protected from freezing.
• Fan motors are permanently lubricated and do not need further lubrication. Motors and fan
assemblies should be inspected on a yearly basis for wear during preventative maintenance
checks.
• 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, insure the DHW
plumbing is properly purged of air. Consult with your installing dealer before draining the hot
