have consulted with the power company and the voltage condition has been corrected.

IMPORTANT

If unit is equipped with a crankcase heater, it should be energized 24 hours before unit start−up to prevent compressor damage as a result of slugging.

UNIT START−UP

1.Rotate fan to check for binding.

2.Inspect all factory− and field−installed wiring for loose connections.

3.Verify that the manifold gauge set is connected as illustrated in figure 17. Use a temperature sensor positioned near the liquid line service port as illustrated in figure 17 which will be required later when using the subcooling method for optimizing the system refrigerant charge.

4.Replace the stem caps and tighten to the value listed in table 1.

5.Check voltage supply at the disconnect switch. The voltage must be within the range listed on the unit’s nameplate. If not, do not start the equipment until you

6.Open both the liquid and vapor line service valves to release the refrigerant charge contained in outdoor unit into the system.
