be vacuumed 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.
INSTALLATION
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.
Elbows
To achieve optimum performance, first, allow a 2 – 3 foot straight
run out of the unit before the first elbow for air flow momentum. An
installation that has a 90-degree elbow immediately after the fan
exhaust port will cause air to back flow into the fan.
Second, use a long radius angle to help ensure optimum airflow
and minimum noise.
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.
Optional Accessory – 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) airflow
through a 5.5"-5.75" hole in the building envelope. And
due to the dividers inside the bottom portion of the unique
Y-shape chamber and the new wall cap, cross contamination
is prevented.
MAINTENANCE (Cleaning)
Maintenance instructions can be found in the Operating Manual.
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.
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
