GENERAL

GENERAL INFORMATION

The ventilator should only be installed by a trained
heating and air conditioning technician.  These
instructions serve as a guide to the technician installing
the ventilator package.  They are not intended as a step
by step procedure with which the mechanically inclined
owner can install the package.

The ventilator housing is shipped in one carton which
contains the electrical harness, miscellaneous hardware
and installation instructions.

UNPACKING

Upon receipt of the equipment be sure to compare the
model number found on the shipping label with the
accessory identification information on the ordering and
shipping document to verify that the correct accessory
has been shipped.

Inspect the carton housing of each ventilator as it is
received, and before signing the freight bill, verify that
all items have been received and that there is no visible
damage.  Note any shortages or damage on all copies of
the freight bill.  The receiving party must contact the
last carrier immediately, preferably in writing,
requesting inspection by the carrier’s agent.  Concealed
damage not discovered until after loading must be
reported to the carrier within 15 days of its receipt.

DESCRIPTION

The CRVS-3, CRVP-3 and CRVP-3L ventilators are
designed to be used with Bard 1½ through 3 ton wall
mount series heat pumps and air conditioners.  They are
electromechanical vent systems designed to provide
fresh air to meet indoor air quality standards.

MODELS:

When installed in the above listed models, the CRV
provides built in exhaust provisions.  When the damper
blade opens to bring fresh air in, the damper also opens
an exhaust relief.  The exhaust air will flow into the
condenser section of the unit.  The condenser fan will
help draw exhaust air out.
