8. Set the temperature mode above room temperature.
The unit should stop.
9. Instruct the homeowneron unit and thermostatoperation
and filter servicing.
System Coolinq
Set the thermostat's system mode to COOL and the
fan mode to AUTO. Change the thermostat temperature
selector below the existing room temperature. Allow the
cooling system to operate for several minutes and check
for the discharge of cool air at the supply registers.
Emerqencv Heat
(Available only when Electric heat is supplied) Set the
thermostat's system mode to EM HT and the fan mode
to either AUTO (intermittent air) or to ON (continuous air).
Change the thermostat's temperature selector above the
existing room temperature and check the following:
1. The thermostat auxiliary heat light (RED) should be on.
2. The compressor and fan should not run; low voltage
circuit remains energized.
3. The blower will run according to the thermostat's fan
mode setting.
Adjustment of Refrigerant Charge
CAUTION:
This air conditioner contains liquid and gaseous
refrigerant under pressure. Adjustment of
refrigerant charge should only be attempted
by qualified, trained personnel thoroughly
familiarwith the equipment and safe responsible
refrigerant handling procedures. Under no
circumstances should the homeowner attempt
to install andlorservice this equipment. Failure
to comply with this warning could result in
equipment damage, personal injury, or death.
• To achieve rated capacity and efficiency the compressor
must be exposed to refrigerant for at least 24 hours
prior to running.After unit startup, the compressor must
run for a minimum of 12 hours.
• The refrigerant charge can be checked and adjusted
through the service ports provided external to the
unit. Use only gage line sets which have a "Schrader"
depression device present to actuate the valve.
