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 (check parts list below). 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 stepby-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.

(1) CRV-F5 ventilator
(2) 7003-084 mist filters
(1) 7003-083 exhaust bug screen

(1) 539-414 exhaust damper assembly
(1) 2100-696A installation instructions
Commercial Room Ventilator Features
• Exhaust air damper – built in with positive closed
position. Provides exhaust air capability to prevent
pressurization of tight buildings.
• Actuator motor – 24 volt, power open, spring return
with built in torque limiting switch.
Description
The CRV-F5 ventilator is designed to be used with
the specific models with "letter" revision codes as
designated on the front page of this installation
instructions manual.
The ventilator is an electromechanical vent system
designed to provide fresh air to meet indoor air quality
standards.
Models
When installed in the models listed on the front page,
the CRV-F5 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.
