M. TROUBLESHOOTING
SOLUTION
•
Turn the unit to the on position and raise or lower temperature setting (as
appropriate) to call for operation.
•
Plug into a properly grounded 3 prong receptacle. See "Electrical Rating
Tables" on Page 6 for the proper receptacle type for your unit.
•
Press and release RESET (Listen for click. Reset button latches and
remains in.) to resume operation.
•
Reset the circuit breaker, or replace the fuse as applicable. If the
problem continues, contact a licensed electrician.
•
The unit will resume normal operation once power has been restored.
•
The unit requires a dedicated outlet circuit, not shared with other appliances.
•
Do NOT use an extension cord with this or any other air conditioner.
•
Replace with a circuit breaker or time-delay fuse of the proper rating. See
"Electrical Rating Tables" on Page 6 for the proper circuit breaker/ fuse rating
for your unit. If the problem continues, contact a licensed electrician.
•
Press and release RESET (Listen for click. Reset button latches and
remains in.) to resume normal operation.
•
Once the problem has been determined and corrected, press and
release RESET (Listen for click. Reset button latches and remains in.)
to resume normal operation.
•
Ensure that the return and/ or discharge air paths are not blocked by
curtains, blinds, furniture, etc.
•
Ensure that all windows and doors are closed.
•
Adjust the Temperature control to a cooler or warmer setting as necessary.
•
Clean the filter, (see Routine Maintenance), or remove obstruction.
•
Clean the coils, (see Routine Maintenance), or remove obstruction.
•
Be sure to use exhaust vent fans while cooking or bathing and, if possible,
try not to use heat producing appliances during the hottest part of the day.
•
Allow additional time for the air conditioner to cool off a very hot room.
•
Do not try to operate your air conditioner in the cooling mode when the
outside temperature is below 60 °F (16 °C). The unit will not cool properly,
and the unit may be damaged.
•
Since the fan does not circulate the room air continuously at this setting,
the room air does not mix as well and hot (or cold) spots may result. Using
the continuous fan setting is recommended to obtain optimum comfort
levels.
•
Check the cooling capacity of your unit to ensure it is properly sized for the
room in which it is installed. Room air conditioners are not designed to cool
multiple rooms.
•
Check the heating capacity of your unit. Air conditioners are sized to meet
the cooling load, and heater size is then selected to meet the heating load. In
extreme northern climates, room air conditioners may not be able to be used as
a primary source of heat.
