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

The WCRVPS*P 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 WCRVPS*P 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.
