Connections
Line voltage wiring must be field installed between the blower junction box and the
evaporative cooling module junction box. The tubing-encased wires are factory-
connected in the cooling module junction box.
NOTE:
Models ADF/ADFH have only 115V optional evaporative cooling module
pumps. A transformer is included on the unit.

Instructions for
“Internal Field-
Required Wiring
From Cooling Module
to System Cabinet
WARNING: Disconnect
power to the unit.
NOTE: The two snap strain relief bushings are shipped in the bottom pan of the
cooling module.
1. Remove the compartment door panels and electrical compartment cover.
Remove the service panel in line with the hole in the cooling module.
2. Drill a 7/8" hole in the cabinet end panel in line with the hole in the cooling
module junction box.
3. Pull the tubing-encased wires through the hole in the blower cabinet. Place the
strain relief bushings around the tubing and insert the bushing into the hole
(Bushing must be used to prevent water from leaking into the cabinet). Route
the wires across the cabinet bottom. If there are any filters, run the wires
through the slot in the bottom filter rack. If there are inlet dampers, be careful
that the wires do not interfere with the damper controls. Run the wires up to
the electrical compartment, remove a plug from one of the bottom entrance
hole, and push the tubing-encased wires into the electrical compartment. Place
the other strain relief bushing around the tubing and insert the bushing into the
hole in the electrical compartment.
4. Follow the wiring diagram included with the heater to properly connect the
wires to the terminal blocks. If there is excess tubing and/or wiring, trim
before making connections.
5. Before unit is operated, replace all door panels and fasten all latches.
