Preventative Maintenance
Air conditioners require regular cleaning of the condenser air inlet filter. Wash filter often if washable
using proper cleaning compound and back flushing the dirt out, or replace if not washable whenever it
appears physically dirty. Restriction to the flow of air over the condenser coil will degrade the
performance of the equipment, cause it to overheat, reduce cooling and can damage the compressor.
The overload switch in the compressor may cause the compressor to cycle if the condensing coil
pressure becomes too high due to air restriction. A further safety feature is the refrigerant high
pressure cut off switch which will stop the compressor if the condensing pressure becomes too high
due restricted condenser air flow or some other cause.
Restricted air flow due to neglecting a dirty filter will cause unit to repeatedly turn off and then turn
back on after it cools off.
An operation in this safety cycling mode will eventually damage the equipment and
void the warranty.
Refer to Field Serviceable Parts section in this manual for details on parts that can be changed to help
increase the uninterruptable life of the Air Conditioner.
Air Filter Service
Remove the air conditioner filter and wash if washable or replace if not washable. Dry thoroughly
before replacing. THERMAL EDGE Air Filter Treatment Spray in aerosol cans or spray bottle is
recommended to enhance air filter efficiency. Replacement filters are readily available from THERMAL
EDGE Customer Service. DO NOT operate the air conditioner without the air filter. Such operation will
allow the condenser coil to become dirty and loose efficiency, causing overheating and diminished
cooling capacity. Dirty condensing coils must be back-flush cleaned using proper commercial coil
cleaning compounds and thorough back-flush rinsing. Refer to directions on the cleaning compounds
selected. Acid wash is not recommended as it reduces the life of the coil.
Note:
Do not use solvents to clean the programmable thermostat. Wipe with mild soap and water.
Condenser and Evaporator Fans
Thermal Edge air conditioners use high efficiency, long life, sealed ball bearing fans engineered for
optimum performance that require no maintenance. Keep fan blades clean for optimal performance.
Fans are removable and attached by plug in connections.
Compressor
Thermal Edge uses hermetically factory sealed compressors that are quiet, low vibration and are
maintenance free. Thermal overload devices are installed to protect the compressor from damage
due to overheat and short cycle faults. If the compressor thermal overload fails, it is recommended to
return the unit to Thermal Edge customer service for proper replacement. Note that the rotary
compressor runs with compressed refrigerant gas on the outer case and therefore is hot to the touch.
Loss of Refrigerant
Thermal Edge air conditioners are meticulously leak and run tested after assembly. If a leak in the
system should develop due to shipping damage or mechanical vibration, the leak must be detected,
repaired and the refrigerant charge restored to the system by a qualified refrigeration professional.
