Installing The Wall Mounted Evaporator Unit - WhisperKool PLATINUM SPLIT 4000 Condenser Technician Manual

INSTALLING THE WALL-MOUNTED EVAPORATOR UNIT
(FAN COIL UNIT)
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 13½" 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 1¾" 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, and electrical.
7. Raise the evaporator to the installation location. Align the rear key
holes with the mounting screws and mount the unit.
8. Using a ¼" wrench or socket, tighten the top mounting screws.
9. Using ¼" and ½" 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. Note: ½" copper tubing will slip over the 3/8"
suction line on the evaporator for an easy connection.
10. Remove the solenoid coil and wrap the solenoid valve in 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.
14. Cut a short piece of ½" drain line and connect a half-inch 90° barb
fitting to the drain line.
15. Route the drain line out of the housing through the hole for the
drain line. Use the second 90° barb fitting if going through the
bottom of the housing. Be sure to extend the tubing far enough
outside the housing to extend through the wall if necessary.
16. Using the cable ties and cable tie mounts provided, secure the
drain line to the bottom of the housing to ensure a downward
slope.
17. Route the power supply wires into the unit through the knockout.
