Installing The Fully Ducted Evaporator Unit - WhisperKool PLATINUM SPLIT 4000 Condenser Technician Manual

INSTALLING THE FULLY DUCTED EVAPORATOR (FAN COIL UNIT)
1. If mounting the unit to a wall, see steps 1-8 of the instruction for installing the Wall-Mounted Evaporator Unit.
2. 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.
3. Remove the solenoid coil and wrap the solenoid valve in a wet rag to prevent overheating.
4. To prevent oxidation, purge the system with nitrogen.
5. Braze the copper tubing to the connections on the Evaporator Unit.
6. Insulate the suction line using Armaflex or similar insulation.
7. Cut a short piece of ½" drain line and connect a half-inch 90° barb fitting to the drain line.
8. 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 pass through the wall if
necessary.
9. Using the cable ties and cable tie mounts provided, secure the drain line to the bottom of the housing to ensure a
downward slope.
10. Route the power supply wires and the circular connector from the 50-ft bottle probe into the unit through the knockout for
the electrical.
11. Remove the wire nuts from the black, white, and green wires located in the lower left corner of the Evaporator Unit.
12. Following the supplied wiring diagram, connect the power supply wires to the black, white, and green wires using the
supplied wire nuts.
13. Connect the bottle probe to the circular connector located in the lower left side of the housing. Follow the directions on
page 33 for correct installation and placement of the bottle probe.
14. Install the supplied black strain relief to secure the power supply wires and bottle probe wire in the housing.
15. Route the communication cable from the remote keypad into the evaporator housing.
16. Connect the communication cable to the circular connector located in the lower left corner of the housing.
17. Secure all wiring neatly and as close to the left wall as possible in order to minimize airflow obstruction.
18. See page 14 for drain line routing instructions.
