HOT GAS BYPASS — When low-load operation requires
use of hot gas bypass, hot gas must be introduced between
expansion valve and distributor.
Install auxiliary hot gas bypass side connector (field-
supplied) in coil split that is first on, last off.
NOTE: See Table 21 for auxiliary side connector sizes. Do
not attempt to use a valve that is smaller or larger than dis-
tributor size. Inserting a bushing at the outlet will defeat the
purpose of the internal nozzle tube extension.
Install the side connector as follows:
1. Remove distributor nozzle and retainer ring (area A) from
distributor and reinstall in inlet (area B) of side connec-
tor. See Fig. 49.
2. Solder field-supplied extension nipple to coupling on dis-
tributor, then to side connector outlet, using a silver
solder or equivalent with a melting point of 1300 to
1500 F. Extension nipple should be as short as possible.
3. Solder expansion valve outlet to side connector using
95-5 tin-antimony soft solder, for easy removal.
4. If required, install field-supplied adapter bushing or
coupling to connector inlet before soldering to expansion
valve outlet.
