Special Remarks; Using The 12-Hour On And Off Timer - Sanyo SAP-K77GHAX Technical & Service Manual

Special Remarks

''DRY'' ( ) Operation
How it works?
• Once the room temperature reaches the level that
was set, the unit repeats the cycle of turning on and off
automatically.
• During DRY operation, the fan speed is automatically
set to Low speed for providing a comfortable breeze.
• ''DRY'' operation is not possible if the indoor temperature
is 15 °C or less.
Heating ( ) Operation
Heating performance
• Because this air conditioner heats a room by drawing
in the heat of the outside air (heat pump system), the
heating efficiency will fall off when the outdoor tempera-
ture is very low. If sufficient heat cannot be obtained
with this air conditioner, use another heating appliance
together with it.
Defrosting
• When the outdoor temperature is low, frost or ice may
form on the heat exchanger coil, reducing heating
performance. When this happens, a microcomputer
defrosting system operates. At the same time, the fan
on the indoor unit stops and the OPERATION lamp
lights until defrosting is completed. Heating operation
restarts after several minutes. (This interval will vary
slightly depending upon the outdoor temperature and
the way in which frost forms.)
Cold draft prevention
• For several minutes after the start of heating
operation,the indoor fan will not start running until
the indoor heat exchanger coil has warmed up
sufficiently. However, the fan may remain stopped
when the room temperature is low. This is because
the COLD DRAFT PREVENTION SYSTEM is
in operation.
Power failure during
operation
• In the event of power failure, the unit will stop.
When the power is resumed, the unit will restart
automatically within five minutes by the remote
control unit.
Clicking Sound
Clicking sound is heard from the air conditioner
• In heating or cooling operation, any plastic parts
may expand or shrink due to a sudden temperature
change. In this event, a clicking sound may occur.
This is normal, and the sound will soon disappear.
Remote Control Unit
• The remote control unit sends the setting condition
to the air conditioner regularly at five minute intervals.
