GENERAL INFORMATION
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.
General
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.
Description
Commercial room ventilators CRV-F2 and CRV-F3 are
designed to be used with the specific models with
"letter" revision codes as designated on the front page
of this installation instructions manual.
The CRV-F ventilator is an electromechanical vent
system designed to provide fresh air to meet indoor air
quality standards.
Commercial room ventilators CRV-F2 and CRV-F3 are
internally mounted dampers with exhaust designed
to provide up to 50% fresh air. The damper blade
is powered by a 24 VAC motor with spring return on
power loss. The damper is powered open anytime A
is energized. Blade stop screws are located under the
fresh air blade and will provide 10 different airflow
settings.
When installed in the models listed on the front page,
the CRV-F 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 when it
is operating with compressor in cooling or heat pump
mode.
Application
The amount of outside fresh air brought into the
structure is dependent on the supply and return duct
static pressure present in the duct system. Refer to
Graphs 1-4 on pages 12-13 for ventilation air that
will be supplied at different blade settings and duct
static pressures. For duct-free applications with return
air filter grilles and supply grilles, use 0.00 supply air
static pressure.
