Remove the Knockout(s) you will be using to route the
Line Set into the unit.
4.
Remove the Knockout(s) that you will be using to route
the items on the previous page into the unit (power
cable wiring, keypad cable, bottle probe cable, and
humidistat cable).
6.
Using 1/4” and 1/2” copper tubing, route the liquid and

Place a wet rag around the suction and liquid lines
approximately 4” from the braze joints. This will
prevent excess heat from damaging components.

To prevent oxidation, purge nitrogen through the
system.
