3. Install the discharge nozzle onto the condenser heat exchanger connection using the correct
gaskets and hardware. Verify that the discharge pipe is level in both directions. Install the
discharge isolation valve on top of the discharge pipe using correct gaskets and hardware.
Note that the actuator valve uses O-rings instad of a flat gasket. If you use any oil on the O-
ring, ensure that you use York K oil. See the discharge line weight in Table 19.
4. Lift a compressor/motor assembly and remove the packing materials (see Figure 26 for
rigging). Carefully lower the compressor/motor assembly on to the supports on the condenser
discharge valve. Fasten with the correct hardware. Do not tighten the bolts until all connections
are made to the compressor.
5. Install the suction line nozzle onto the evaporator heat exchanger connection using the correct
gaskets and hardware. See the discharge line weight in Table 19.
