6 REFRIGERANT DISTRIBUTOR NOZZLES
Distributor nozzles are included using a refrigerant distributor with a changeable nozzle design.
The nozzle(s) are packed in individual plastic envelopes along with a retainer ring and instruction card.
The instruction card provides information on nozzle used based on refrigerant. There may be one, two,
or three envelopes with nozzles located near the distributor.
The nozzles provided with the unit have been selected for design conditions of 10°F T.D. and 95°F liquid
refrigerant at the expansion valve inlet. If the unit will be operated at conditions that are substantially
different from these conditions, it may be necessary to select a different size nozzle. Consult factory for
additional information.
The nozzle must be installed in the distributor or the auxiliary side connector before the expansion
valve is installed. There are nozzle identification numbers stamped on one side of the nozzle. Ensure
the numbers are visible (for identification information) when inserting the nozzle into the distributor.
The nozzle is held in place by a retainer ring that is easily inserted or removed with a pair of needle
nose pliers.
The standard distributor nozzles provided with the units are listed in TABLEs 2A, 2B, and 2C:
