Page 35: Brazing Procedure
Be sure tube fitting inner surface and tube outer surface are clean prior to assembly. ▪ Both tubes are extended from the condensing unit housing, therefore Emerson recommends isolating the housing by using a wet cloth on the copper tubing. -
Page 36: Required Distances
Where multiple units are to be installed in the same location, the contractor needs to consider each individual case carefully. There can be many variations of unit quantities and available space and it is not the intention of this manual to go over these. However, in general terms, air by-pass around each condenser and between the units should be avoided always. -
Page 37: Starting Up & Operation
Starting up & operation Before commissioning, ensure that all valves on the condensing unit are fully opened. Only qualified personal and certified companies are allowed to do installation, commissioning, service and maintenance work. Evacuation CAUTION System pressure below atmospheric pressure! Compressor damage! Never energize the unit/controller without minimum refrigerant system charge. -
Page 38: Charging Level In Liquid Receiver

Page 42: Electrical Connections
As a rule, and for a clean environment, Emerson recommends that the fins be cleaned with liquid detergent diluted with clean water. The condensing unit has a well-designed chassis, and provided the unit is installed level, any cleaning solution should be able to drain away. A light brush downward (in the direction of the fins) should be done before washing to remove heavy deposits. -
