or recirculating central ventilator for
the introduction of outdoor air, raising
the temperature of the fresh air by
mixing with recirculated indoor air.
When used with adjustable balancing
grilles or ALDES CAR, Constant Airflow
Regulators, and compatible roof/wall
caps, ducting, etc., the fan is the heart
of a complete pre-engineered ventilation
system.
Unpack the unit, taking care to look
for any loose components among the
packing material. Make certain that the
fan housing and the blower is free of any
loose packing material or small parts.
If not removed before startup, damage
and injury may result from solid objects
discharged by the blower. Inspect for
damage, loose or missing parts.
WARNING
TO REDUCE THE RISK OF FIRE,
ELECTRIC SHOCK, OR INJURY
TO PERSONS, OBSERVE THE
FOLLOWING:
A. Use this unit only in the manner
intended by the manufacturer. If
you have any questions, contact the
manufacturer.
Install the unit in its final location. The
fan may be installed in a mechanical
room, crawl space or attic. It is designed
to be placed on a flat surface, against
a wall or trusses, or suspended from
above. If set on a flat surface, vibration
isolation pads are recommended.
SYSTEM DESIGN:
Satisfactory performance of a central
ventilation system requires the proper
integration of all the components:

Corporation is not responsible for
the fan. The brackets may be mounted
to the fan using the self-drilling screws
and rubber grommets provided, at the
locations indicated by dimple marks
on the side and bottom panels of the
fan. Pan head number 10 screws are
provided to attach the mounting bracket

Handle the unit with care to prevent
damage to the housing and other
components. Store the unit indoors if
possible. If outdoor storage is required,
protection against moisture and dirt is
necessary.
For installations in which the fan is connected to a range hood, or if an exhaust grille connected to the fan
is located near the cooking surface as shown below, be sure to observe the following safety warnings:
WARNING
TO REDUCE THE RISK OF FIRE, USE ONLY
GALVANIZED STEEL DUCTWORK WHERE
REQUIRED TO USE METAL DUCT.
(Note: If the fan is not connected to a range
hood or a grille in the vicinity of the cooking
surface, other approved ducting may be used
as described in "Ducting" section of basic
instructions.)

TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE TOP
GREASE FIRE, OBSERVE THE FOLLOWING:
A. Never leave surface units unattended
at high settings. Boilovers cause
smoking and greasy spillovers that
may ignite. Heat oils slowly on low or
medium settings.
A. SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal tray, then turn off the
burner. BE CAREFUL TO PREVENT BURNS. If the flames do not go out immediately
EVACUATE AND CALL THE FIRE DEPARTMENT.
B. NEVER PICK UP A FLAMING PAN - You may be burned.
C. DO NOT USE WATER, including wet dishcloths or towels - a violent steam explosion
could result.
B. Always turn hood ON when cooking at
high heat or flambeing food (i.e. Crepe
Suzette, Cherries Jubilee, Peppercorn
Beef Flambe).
D. Use an extinguisher ONLY if:
1. You know you have a Class ABC extinguisher, and you already know how
to operate it.
C. Clean ventilating fans frequently.
Grease should not be allowed to
accumulate on fan or filter.
2. The fire is small and contained in the area where it started.
3. The fire department is being called.
D. Use proper pan size. Always use
cookware appropriate for the size of
the surface element.
4. You can fight the fire with your back to an exit.

General: MPVS Series multi-port
ventilators are highly versatile continuous
duty rated fan units for residential and
light commercial applications, and meet
ENERGY STAR efficiency criteria for
low energy consumption. The most
popular use is central continuous exhaust
ventilationofbathrooms,kitchens,laundry
rooms, and other rooms where humidity
is a controlling factor, since the fan has a
single exhaust discharge duct directly to
the outdoors.

SERVICE AND
INSPECTION
The principle advantage of the MPVS
central exhaust system is the assurance
of controlled indoor air quality ventilation
and the elimination of standard noisy bath
fans, with the obvious benefits of reduced
penetrationstotheexteriorofthebuilding.
Withtheincreasedtightnessofconstruction
for energy efficient buildings, there is a
growingneedofmechanicalventilationfor
indoorairquality. Thesefansaredesigned
to serve this purpose as well, by providing
effective bathroom ventilation, with the
ability to run intermittently or continuously
as needed. The quiet, energy efficient
permanent split capacitor external rotor
motor has permanently sealed bearings
that provide many years of maintenance-
free performance.
DIMENSIONS:
MPVS 100 and 120
Duct Configuration(s) 313, 323, and 333
Construction: The MPVS fan is
constructed of heavy gauge galvanized
steel to prevent corrosion caused by
moisture. The cabinet is internally lined
with UL rated, acoustic closed-cell foam
vapor barrier insulation. This allows
installation directly above living spaces,
or in unheated plenum spaces without
concern for noise or condensation.

Locating and Installing the Fan:
The compact dimensions and
