VPC / VPP, and VPH models provide a complete air-conditioning and optional heating system as an all-in-one pack-

age, capable of providing total heating and cooling functions for a single zone or multiple rooms. Specically designed

for convenient through-the-wall installation in residential high rise and hospitality industry applications. The all-indoor

design eliminates the need for unsightly exterior equipment, thereby maintaining architectural esthetics.

All units are shipped completely wired and factory tested. The refrigeration section features enhanced refrigeration

coils, a bi-ow thermostatic expansion valve for refrigerant control, and a high efciency Scroll or rotary compres-

sor. The VPP units incorporate a reversing valve to allow operation on a heat pump cycle. Air circulating fans are

centrifugal, direct driven. The indoor fan motor allows operation at three different fan speeds.

The standard VPC & VPH units may be operated on the cooling cycle to an outdoor ambient of 40ºF. The low ambient

cooling package will cycle the compressor to prevent frosting of the evaporator at low outdoor ambient temperatures.

The VPP unit locks out compressor operation (refrigerant heating) at outdoor ambient temperatures below 40ºF.

4. UNPACKING

a) Check the unit for indications of damage in ship-

ment. Notify the Transportation company of any

damage and note the damage on the shipping

receipt.

Rough handling may dislocate internal

components.

b) Allow the shipping base to remain with the unit

until it is ready to be set in its nal location.

c) Rotate blowers to assure free movement.

d) The compressor is mounted on neoprene isolators

with metal spacing sleeves inside and secured with

nuts, which must be snug against the metal spacer

sleeves.

e) Check all refrigeration tubing to assure that it does

not rub against any other parts.

5. NORMAL INSTALLATION

This unit is designed for indoor installation adjacent

to an outside wall having an opening for outdoor air

ow. The air ow products must:

a) Discharge directly to the outside.

b) Discharge away from any obstructions which could

cause discharged air recirculation.

6. CLEARANCES

The unit is design certied for closet installation with

the minimum clearances to combustible materials as

stated on the data label. No clearance is required

from the top, sides, or back of the unit. A minimum

of 1 inch clearance is required from the front to any

combustible materials. A combustible door may be

placed 6 inches from the front of the unit. When the

door is open there must be 30 inches clearance to

any obstruction, to allow sufcient access for service

and the replacement of parts.

D = (29” – B)

Outside Wall Thickness 8”-12”

D = (33” – B)

Outside Wall Thickness 12”-15”

D = (36” – B)

7. WALL OPENING

A nished opening in an outside wall is required

for intake and exhaust of outdoor airow. The wall

opening required is 21-3/4” wide by 44” high. The

bottom edge of wall opening must be located at least

6” higher from nished oor

Consult local ordinances for building opening fram-

ing requirements.

8. WALL SLEEVE

A factory-made wall sleeve is required to nish

the wall opening. The sleeve should be positioned

with a minimum of ¼” protruding from the nished

outside wall face. This projection allows installation

of the exterior grille without interference from the

exterior nishing materials, and provides a right

angle surface to apply a caulking bead around the

wall penetration.

Use a spirit level or plumb line to make sure that the

wall sleeve vertical anges, which must mate with the

back of the unit, are perfectly vertical. The sleeve

must be secured to the building framing with suitable

eld-supplied fasteners (i.e. lag screws). (NOTE:

Use shims as necessary, between the sleeve and

the rough wall opening, to compensate for any ir-

regularities at the sleeve fastening locations.) DO

NOT allow the fasteners to distort the wall sleeve

side panels.

A roll of ¾” wide x ½” thick self adhesive foam gasket

is packed in the blower compartment of the unit, to

be used for sealing between the wall sleeve and the

unit. Before moving the unit into nal position, apply

self-adhesive foam gasket to all the mating anges

on the wall sleeve, be sure to apply gasket material

to the divider panel ange between the top and bot-

tom sections of the wall sleeve. Also apply gasket

material to the vertical ange of fresh air divider.
