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.
