2.Measure liquid service-valve pressure by attaching an accurate gage to the service port.

3.Measure the liquid-line temperature by attaching an accu- rate thermistor-type or electronic thermometer to the liquid line near the outdoor coil.

4.Refer to unit-rating plate to find required subcooling temperature for units produced during or after January 1993. For units produced through December 1992, refer to Table 23. Find the point at which the required subcooling temperature intersects the measured liquid service-valve pressure on Table 24.

5.To obtain the required subcooling temperature at a specific liquid-line pressure, add refrigerant if liquid-line tempera- ture is higher than indicated or remove refrigerant if temperature is lower. Allow a tolerance of 3°F.

CARE AND MAINTENANCE

To assure high performance and minimize possible equipment malfunction, it is essential that maintenance be performed periodi-

—45—

cally on this equipment. The frequency with which maintenance is performed is dependent on such factors as hours of operation, geographic location, and local environmental conditions.

WARNING: Disconnect all electrical power to unit before performing any maintenance or service on outdoor unit. Remember to disconnect power supply to air handler as this unit supplies low-voltage power to the outdoor unit. Electric shock can cause personal injury or death.

The minimum maintenance that should be performed on this equipment is as follows.

1.Check outdoor coil for cleanliness each month during the heating (heat pump only) or cooling season and clean as necessary, but clean at least once each heating (heat pump only) and cooling season.

2.Check fan motor and blade for cleanliness each heating and cooling season and clean as necessary.
