2. Set thermostat above room temperature and observe
the ignition sequence.
NOTE:
The burner flame should carry over immediately
between all burners without lifting off, curling, or floating.
The flames should be blue, without yellow tips. Make
sure the flame is drawn into the center of the heat
exchanger tube. In a properly adjusted burner assembly,
the flame bends down and to the right at the end of the
heat exchanger tube. The end of the flame will be out
of sight around the bend.
3. After validating flame characteristics, set the thermostat
below room temperature and verify the burner flame
extinguishes completely.
Verifying System Cooling
(Single Stage Operation)
WARNING:
These units are shipped fully charged with
R-410A refrigerant and ready for installation.
When a system is installed according to these
instructions, no refrigerant charging is required.
If repairs make it necessary for evacuation and
charging, it should only be done by qualified,
trained personnel thoroughly familiar with this
equipment. Some local codes require licensed
installation/service personnel to service this type
of equipment. Under no circumstances should
the owner attempt to install and/or service this
equipment. Failure to comply with this warning
could result in property damage, personal injury,
or death.
CAUTION:
This unit uses R-410A refrigerant. DO NOT use
any other refrigerant in this unit. Use of another
refrigerant will damage the unit.
1. Set the thermostat’s system mode to COOL and the
fan mode to AUTO. Gradually lower the thermostat
temperature setpoint below room temperature and
verify the compressor, fan and indoor blower energize.
2. Feel the air being circulated by the indoor blower and
verify that it is cooler than ambient temperature. Listen for
any unusual noises. If unusual sounds occur, determine
the source of the noise and correct as necessary.
3. Allow the cooling system to operate for several minutes
and then set the temperature selector above room
temperature. Verify the fan and compressor cycle off
with the thermostat.
NOTE:
The blower will also stop
after a 60 second delay.
The system refrigerant charge can be checked and
adjusted through the service ports provided at the front
panel. Use only gauge lines which have a “Schrader”
depression device present to actuate the valve. Draw a
vacuum on gauge lines to remove air before attaching
them to the service ports on the unit. Refrigerant charging
must be done by qualified personnel familiar with safe
and environmentally responsible refrigerant handling
procedures.
