Installation

! WARNING

Hazardous Voltage!

Disconnect all electric power, in- cluding remote disconnects be- fore servicing. Follow proper lockout/tagout procedures to en- sure the power can not be inad- vertently energized. Failure to disconnect power before servic- ing could result in death or seri- ous injury.

Wiring (continued)

DX System

A typical unit ventilator with DX coil in- cludes an outside air thermostat, a frost prevention thermostat and a 24V transformer for condensing unit con- trol.

Wire sizing is the same as given for the thermostat wiring in the condensing unit installation instructions, or may be obtained from the nameplate. The condensing unit must be controlled by the same room thermostat that also controls the unit ventilator.

Split System Start-Up

After all piping and wiring has been completed, follow the instructions provided with the condensing unit for control testing and system start-up. If sweat type field-piped systems are be- ing used, then pressure testing, evacu- ation and refrigerant charging will be required.

Two bulbs will also be shipped with a split system unit:

Frost stat bulb

TXV valve (used with R410a).

Both components are to be field in- stalled using the installation kit shipped with the unit. For complete in- stallation instructions and locations, refer to the tag attached to the installa- tion kit within the unit. See Figure 15 for an example of the installation tag.
