Grounding
WARNING:
The unit must have an uninterrupted
or
unbroken
electrical ground to minimize
personal
injury
if an electrical
fault
should occur.This
ground may consist of
electrical wire or approved conduit when
installed in accordance
with national
or
local
codes.
STARTUP AND ADJUSTMENTS
Pre-Start
Checklist
The following check list should be observed prior
to starting the unit.
Is the unit level? Unit should be level or slightly
slanted toward the drain for proper condensate
drainage.
Is the wiring correct according to the wiring
diagram and electrical codes?
Inspect wiring for evidence of open, shorted,
and/or improperly wired circuits.
_ Are all the wiring connections
tight? Check
the condenser fan to make sure it turns freely.
Is the overcurrent
protection
properly sized?
Is the thermostat wired correctly? Is it installed
in a proper location?
4 Verify air filters are clean and in place prior to
operating the equipment.
_ Verify the outdoor coil and top of the unit are
free from obstructions
and debris, and all
equipment access/control
panels are in place.
Thermostat
Set the thermostat's
system mode to OFF, the
fan mode to AUTO, and adjust the temperature
setpoint to its highest setting.
Outdoor
Unit
Prior to applying electrical power to the outdoor
unit, verify that the unit has been properly and
securely
grounded,
and that power
supply
connections
have been made at both the facility
power interface and outdoor unit.
FUNCTIONAL
CHECKOUTS
CAUTION:
These
units
have a crankcase
heater
factory
installed. Wait 24 hours prior to
performing
a function
checkout
to allow
for heating of the compressor
crankcase.
Failure to comply
may result in damage
and could
cause
premature
failure
of
the system.
Cooling
Gradually
lower the thermostat
temperature
setpoint
below
the actual
room temperature
and observe that the outdoor unit and indoor
blower energize.
Feel the air being circulated
by the indoor blower and verify that it is cooler
than ambient temperature. Listen for any unusua!
noises. If unusual sounds occur, determine
the
source of the noise and correct as necessary.
Heating
If heating equipment
(furnace,
air handler) is
provided with the system, lower the thermostat
setpoint temperature
to the lowest temperature
setting and change the thermostat's
function
mode to HEAT. The outdoor
unit should
stop
ru nning and the indoor blower will shut off after the
preprogrammed
delay. Increase the thermostat's
setpoint temperature
to the maximum setting.
Verify the heating equipment
and the indoor
blower energize after a short period of time. Feel
the air being circulated by the indoor blower and
verify that it is warmer than ambient temperature.
Listen for any unusual noises. If unusual sounds
occur, determine
the source of the noise and
correct as necessary.
NOTE: Other heating sources (electric furnace,
fossil fuel furnace,
air handler
with electric
heat options,
etc.) that interface
with the air
conditioner
should be functionally
checked to
verify system operation and compatibility.
Refer
to the installation instructions for this equipment
and perform a functional checkout in accordance
with the manufacturer's
instructions.
indoor
Blower
1. Turn the fan mode to ON. Verify that the
indoor blower is operating and that airflow is
not restricted.
2. Set the fan mode back to AUTO. Blower will
operate at a decreased speed on continuous
fan.
