Maintenance Checklist

Won't Cool
If the unit operates, but doesn't cool, check to see that the controls are properly set. Inspect the filter and if needed, clean it thoroughly.
Check to see if the chassis seal gasket is installed (refer to installation instructions).
Won't Run
If the unit does not operate at all, check that the power supply connections are present and tight. Check for blown fuses or tripped cir-
cuit breakers. Replace blown fuses with the proper size time-delay fuse. The nameplate on the unit shows the proper fuse size. After
restoring power, wait three minutes before restarting the unit.
Inside Coil Freezes Up
Your Friedrich Hazardgard is designed not to freeze with outdoor temperatures as low as 45°F (7°C). Freezing should only occur when
the outside air is damp and below 45°F (7°C). If the indoor coil should ice over while cooling, set the thermostat to the warmest position
until the ice is gone. Setting the thermostat to a slightly warmer position will probably keep ice from forming on the coil. A dirty filter
will contribute to coil icing.
Cleaning
The front grille of your Friedrich, as well as the complete cabinet may be cleaned with warm water and a mild detergent. The coils and
base pan should be cleaned periodically for the most efficient operation. We suggest you call your Friedrich dealer for this service.
Lubrication
Fan motors are factory lubricated and sealed. No lubrication is required.
