an adjustment is made.
NOTE: Some valve bodies (G, EG, C, S, EBS and EMC) have
a packing nut around the adjustment stem. It may be necessary
to loosen the packing nut slightly to turn the adjusting stem.
Do not forget to retighten the nut after the superheat is set.
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.
See Table 34 for auxiliary side connector sizes. Do not attempt to

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 connector.
See Fig. 109.
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. Ex-
tension 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 cou-
pling to connector inlet before soldering to expansion
valve outlet.
