4. Set room thermostat at desired temperature. Be sure set
point is below indoor ambient temperature.
5. Set room thermostat to COOL and fan control to ON or
AUTO mode, as desired. Operate unit for 15 minutes.
Check system-refrigerant charge.
START-UP
CAUTION: To prevent compressor damage or personal
injury, observe the following:
•Do not overcharge system with refrigerant.
•Do not operate unit in a vacuum or at negative pressure.
•Do not disable low-pressure switch.
In scroll-compressor applications:
•Dome temperatures may be hot.
•In 3-phase application, incorrect phasing will cause
reverse rotation, resulting in elevated noise levels, equalized pressures, and reduced current draw. Correct by
reversing power connection L1 and L2 on contactor.
A. Sequence of Operation
Turn on power to indoor and outdoor units. Transformer is
energized.
On a call for cooling, thermostat makes circuits R-Y and R-G.
Circuit R-Y energizes contactor, starting outdoor-fan motor and
compressor circuit. R-G energizes indoor unit-blower relay, starting indoor-blower motor on high speed.
When thermostat is satisfied, its contacts open, de-energizing
contactor and blower relay. Compressor and motors stop.
If indoor unit is equipped with a time-delay relay circuit, the
indoor blower will run an additional 90 sec to increase system
efficiency.
CAUTION: To prevent personal injury wear safety
glasses, protective clothing, and gloves when handling
refrigerant and observe the following:
•Back-seating service valves are not equipped with
Schrader valves. Fully back seat (counterclockwise)
valve stem before removing gage-port cap.
•Front-seating service valves are equipped with Schrader
valves.
XI.
CHECK CHARGE
A.
Unit Charge
Factory charge is shown on unit-rating plate. Adjust charge by
following procedure shown on charging tables located on unit.
NOTE: If superheat- or subcooling-charging conditions are not
favorable, charge must be weighed in accordance with unit-rating
plate ± 0.6 oz/ft of 3/8-in. liquid line above or below 15 ft
respectively.
EXAMPLE:
25 ft – 15 ft = 10 ft X 0.6 oz/ft = 6 oz of additional charge
CAUTION: Do not vent refrigerant to atmosphere. Recover during system repair or final unit disposal.
B.
Cooling Only Procedure
The following procedure is valid when indoor airflow is within ±
21 percent of its rated CFM.
1. Fully back seat (open) liquid- and vapor-tube service
valves.
1. Operate unit a minimum of 10 minutes before checking
charge.
2. Unit is shipped with valve stem(s) front seated (closed) and
caps installed. Replace stem caps after system is opened to
refrigerant flow. Replace caps finger-tight and tighten with
wrench an additional 1/12 turn.
2. Measure suction pressure by attaching a gage to suctionvalve service port.
3. Measure suction temperature by attaching an accurate
thermistor-type or electronic thermometer to suction line at
service valve.
3. Close electrical disconnects to energize system.
