The installer MUST check available power to make certain it

matches the unit nameplate rating and that constant voltage can be

maintained to the unit. Unsatisfactory and unsafe performance

could otherwise result. The local power company should be

contacted about questions concerning power supply.

These units are standard equipped from the factory with a unit

disconnect. This is in the form of a circuit breaker (230V models) or

a disconnect (460V models). If an optional electric heat kit is to be

installed, follow the instructions included with the heater assembly.

See Figure 1 for reference.

The line voltage electrical service can be routed through the right

side panel, the right side of the back panel, or left side panel. Each

area is supplied with two line voltage knock-outs (

"). Low voltage wiring can be routed through the right side panel. 

NOTE:

When routing line voltage through the return air com-

partment, conduit MUST be used (even though this is a dry area) to

comply with the NEC code. A 1

" PVC conduit is supplied for this

application. Refer to the ELECTRICAL DATA tables for minimum

wire size and maximum breaker size. All wire sizes listed under the

dual-feed circuit column are based on no more than three (3)

conductors in the same conduit. If two circuits or more than three (3)

conductors are to be routed in the same conduit, the ampacity of the

wire size listed MUST be derated. Refer to Article 310 of the NEC

code for adjustment factors. Be sure to install a ground wire of the

proper size to the unit’s equipment ground lug.

230 volt, 1- and 3-phase units are equipped with dual-primary

voltage transformers for 208/240 volt operation. These models are

factory wired to the 240 volt tap. For 208 volt operation connect the

factory-installed black wires from the 240 volt tap to the 208 volt tap.

The acceptable voltage range of the tap is as follows.

Tap

Voltage Range

240 Volt

253 - 216

208 Volt

220 - 187

Five (5) conductor thermostat wires should be run from the

thermostat location to the unit. Thermostat wire should be sized as

shown on the table below. 

Refer to wiring diagrams for connection details.

STAGING OF ELECTRIC HEAT

All V Series units with electric heat assemblies above 10 kW may be

wired for single- or two-stage heat. These models come factory wired

for single-stage operation. For two-stage operation, remove the

jumper bar from between the W2 and E terminal. Wire the first-stage

heat to terminal W2. Wire the second-stage heat to terminal E.

V SERIES UNITS ARE FOR USE IN 

SINGLE-STORY BUILDINGS ONLY

1. As previously stated, the wall that the unit is to be installed

onto MUST be strong enough to support the unit under the

condition for which it will be used. For example, a unit to be

installed on a building that is intended to be transported will

require more wall strength than a unit installed at a

permanent site. Existing walls may need additional

reinforcement. NEVER RELY ON EXTERIOR SIDING OR

PLYWOOD TO SUPPORT THE UNIT. Figure 2 below

represents a typical installation of a single-story stud wall at a

permanent site. Since building materials and techniques vary

with regions and intended use, a building contractor and/or

local building code official MUST be consulted for suitable

construction methods.

2. Locate and attach the lower mounting bracket in the desired

location on the building. 

3. Apply a suitable caulk across the entire length of the top rain

flashing and side mounting flanges.

4. Remove the flanges on both ends of the pallet and slide the

unit approximately 2” off the rear of pallet. Lift unit gently into

location with fork truck, taking care to align unit with lower

mounting bracket.

5. While allowing a small portion of weight on the lower bracket,

push the unit against the wall and fasten appropriately.A

drain hose is located on the bottom side of the unit. The drain

may be extended for condensate removal to comply with

local codes (use fitting size or larger). Install a condensate

trap on this line.

A3/4” drain hose is located on the bottom side of the unit. The drain

may be extended for condensate removal to comply with local

codes (use fitting size or larger). Install a condensate trap on this

line.

Electric heat is an option on V Series units and can be field-installed

on either single- or three-phase models.
Refer to the individual installation instructions for installing

heater kits on page 14.
