QV Series Heat Pumps
PROTECTING THE UNIT DURING
CONSTRUCTION
Once the unit is properly positioned on the job
site, cover it with either a shipping carton, vinyl
film, or an equivalent protective covering. Cap
opens ends of pipes stored on the job site. This
precaution is especially important in areas where
painting, plastering, or spraying of fireproof
material, etc. is not yet complete. Foreign material
that accumulates within the units can prevent
proper start-up and require costly clean-up
operations. Before installing any of the systems
components, be sure to examine each pipe, fitting
valves and remove any dirt or foreign material
found in or on these components.
RETURN AND SUPPLY AIR DUCT
FLANGES PREPARATION
QV heat pumps feature fold-out return and supply
air duct flanges. These fold-out flanges come
folded in from the factory to allow the heat pumps
to more easily fit through doorways and other tight
spaces, and also to prevent damage in shipping
and handling.
Following installation of the heat pump fold-out all
fold-out flanges to ensure that return and supply
air flow is not obstructed. These flanges can be
easily folded using standard or duckbill pliers.
Once folded out these flanges can be used to
support light duct work loads.

MOUNTING VERTICAL (VT) UNITS

In order to minimize vibration transmission from
the unit to the building structure mount the QV
Series vertical units on a vibration absorbing pad
slightly larger than the unit base. (See Fig. 2.)
It is generally not necessary to anchor the unit
unless required by local code. All major service
access for the QV Series vertical models is from
the front side of the unit. When installing the unit
in a confined space such as a closet, ensure that
the service panel screws are accessible, that the
filter can be replaced without damage, and that
water and electrical connections are accessible.
For models with a unit-mounted disconnect
switch, make sure the switch can be easily seen
and operated.
QV Series Heat Pumps
To reduce sound transmission, install units using
flexible electrical conduit and hose kits. Care
should be taken to ensure that no part of the unit
cabinet is touching part of the building structure.
For ducted-return applications, a flexible duct
connection should be used.

HORIZONTAL (HZ) UNITS

Configuring the Horizontal Supply Air
Orientation
The supply air location on QV Series Horizontal
units can be field converted from end blow to
straight through or vice-versa.
NOTICE: Blower
should be done prior to unit being installed
in the final location.
