INSTALLING THE WALL-MOUNTED EVAPORATOR UNITS
1/8”
WALL
STUD
1.
Locate two (2) wall studs in the desired mounting location spaced 16” on center.
2.
Mark vertical lines on each stud 16” apart.
3.
Mark an intersecting horizontal line at the desired height of the unit.
4.
Make a mark on each stud 131/2” down from the intersection of the horizontal and vertical lines.
NOTE:
The top of the unit must be installed a minimum of 6” and a
maximum of 18” from the ceiling.
5.
Install the four (4) supplied 13/4” hex-head
screws into the studs at the locations marked
leaving 1/8” between the wall surface and
screw head.
6.
If routing through a wall, cut out an access
hole for the line set, drain line, display cable, and power wires.
7.
Raise the evaporator to the installation location. Align the rear
keyholes with the mounting screws and mount the unit.
8.
Using a 1/4” wrench or socket, tighten the top mounting screws.
9.
Using 1/4” and 3/8” copper tubing, route the liquid and suction lines
through the knockouts in the housing. Be sure to extend the
tubing far enough outside of the housing to extend through the
wall if necessary.
10.
Wrap both sides of the copper tubing with a wet rag to prevent
overheating.
11.
To prevent oxidation, purge the system with nitrogen.
12.
Braze the copper tubing to the connections on the evaporator
unit.
13.
Insulate the suction line using Armaflex or similar insulation.
