Full Product Manual

Exchange Capillary Core
Whisper Comfort's unique core is made from a paper-like material
and should never be washed or submerged in water. To clean,
vacuum with a soft brush attachment. To clean, use vacuum suction
with a soft brush attachment. Do not use a vacuum to blow air
through the ERV core as that may damage the core.
Mounting
WhisperComfort is UL listed for ceiling or wall mount installation.
It 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.

Typical Wall Cap Installation
Elbow
Whisper Comfort's FV-EB04VE1
styrofoam elbow accessory
connects 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) airflow 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 flow momentum, allow a 2-3 foot straight run
of flex duct out of the unit before the first 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.
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.
