S2HA & T2HA REFRIGERANT PIPING INSTALLATION SECTION

FIELD CHARGING

NOTE: If operating superheat is more than 5°F above the chart value, add refrigerant. If below the chart value remove refrigerant. If below the limit line, remove refrigerant.

Example (Using the 12,000 Btuh cooling chart):

1.Suction pressure is 65 psi. which equals 38° F on The R-22 Scale of the Low-

Side Gauge.

2.Suction line temperature taken at the unit is 70° F. 70° F minus 38° F equals 32° F superheat.

3.Outdoor temperature is 90° F, indoor temperature is 80° F.

4.Intersection of the indoor-temperature and outdoor-temperature lines occur on the 12° F superheat line.

5.Add charge to obtain 12° F superheat.

Instructions:

1.Measure suction pressure and determine evaporator-refrigerant temperature on R-22 scale of low-side gauge.

2.Measure suction-line temperature on suction line of the unit.

3.Measure outdoor and indoor tempera- tures.

4.Determine from the table what the super- heat should be for the indoor and outdoor temperatures. (Example indicates 12° F superheat.)

5.Adjust charge if needed. Be sure unit is running at stabilized condition.

NOTE: For installation of the indoor unit and start-up of the system, please refer to the appropriate installation manual for your indoor product to complete the installation.

STARTING THE UNIT

Before starting the unit in cool weather, power the system 24 hours before at- tempting to start.

Do a final system check using the super- heat/subcooling method. Record results on Test Unit Performance Data sheet (next page).

-Cooling mode superheat is set with a proper sized piston and charge, using the field charging charts.

-Heating mode superheat is set with a TXV andshouldbe5°F. Whenchargingasystem in heat mode, use the subcool method field charging charts.

Remove gauge set. Mount all access panels and make sure they are properly secured.

Make final visual inspection and repair any deficiencies.
