Dimensions Guide

Filters
WhisperComfort has two air filters. One filter is located on the inside
louver of the grille. The second filter is located in the unit held by a
bracket with a handle. Pull the handle to remove the filter bracket
and remove the filter from the bracket. Both filters should be vacu-
umed with a soft brush attachment.
Exchange Capillary Core
Whisper Comfort's unique core is made from a paper-like mate-
rial and should never be washed or submerged in water. To clean,
vacuum with a soft brush attachment.

• Rust-proof paint treatment on galvanized housing
• Thermal fuse protection
• Meets Washington State Ventilation and Indoor Air Quality
code and ASHRAE 62.2 -2007
• 3 Year Warranty
Mounting
WhisperComfort measures 14" wide and fits between joists 16" on
center. Adjustable brackets and screws are provided to secure the
unit to the joist on 4 corners.
Wiring
Power consumption is 23 Watts at 40 CFM with a power rating of
120/60 V/Hz. Bring house power to the unit junction box and use 3
wires to connect the 2 switches.
Duct
Insulated 4" duct is recommended. For cold climates, this will help
avoid condensation build up. And for warm climates, this will help
reduce heat transfer to supply air.
In order to reduce unnecessary airflow resistance, duct should be
stretched straight and braced to avoid sagging. Assure that all duct
connections are completely secured with duct tape and/or duct
mastic material.
Termination/Supply Device
The supply device will need to have the back draft damper
removed and replaced with a screen to prevent insects and
small animals from nesting.
The termination and supply devices should be placed a
minimum of 3-feet apart. If placed closer than 3-feet, then the
angle of each device should be mounted at 45-degrees in
opposite directions.
Grille
Follow the Operating Manual to remove the grille from the unit.
Next, remove the filter from the inside louver of the grille. Never use
gasoline, benzene, thinner or any other chemicals when cleaning
the grille or ERV unit. Do not wash grille in a dishwasher which may
cause it to deform. Instead, use light dish soap.

Elbow
Whisper Comfort's FV-EB04VE1
styrofoam elbow accessory con-
nects to the Y shaped adapter
of the exterior wall cap to help
simplify wall installation. The elbow
also features double chambers
for exhaust and supply air to help
prevent cross contamination.
Exterior Wall Cap
Unlike previous installations where two wall caps were
required, WhisperComfort’s FV-WC04VE1 polypropylene
wall cap accessory with styrofoam adaptor conveniently
allows both exhaust (from the right) and supply (from
the left) airow through a 5.5"-5.75" hole in the building
envelope. The dividers inside the bottom portion of the
unique Y shape chamber and the new wall cap help
prevent cross contamination.
To achieve optimum performance and air ow momentum, allow a 2-3 foot
straight run of ex duct out of the unit before the rst 90 degree bend. If you
connect the ERV unit directly to the Y shaped adapter of the exterior wall cap,
you can skip this step.
