.1 INSPECT THE CONTENT OF THE BOX
• Inspect the exterior of the unit for shipping damage. Ensure there is no damage to the door, door latches, main switch, etc.
• Inspect the interior of the unit for damage. Ensure the blower assembly, insulation, prefilter, HEPA filter, etc. are all intact.
• If the unit was damaged during shipping, contact your local distributor.
2.2 LOCATING AND MOUNTING THE UNIT
Choose an appropriate location for the unit.
• Within an area of the house where the ambient temperature is between 10°C (50°F) and 30°C (86°F) (basement, furnace room,
closet, etc.).
• So as to provide easy access to the interior of the unit, for filter maintenance.
• Away from hot chimneys and other fire hazards.
2.3 MOUNT THE PORTS ON THE UNIT
Mount the 8” (HEPA 3.2 unit) oval ports on the top of the unit using the screws provided in the hardware
box (4 screws #8 x 3/4” long per port).
NOTE: If an optional wall control has to be installed, do not install the front oval port (1) at this time.
2.4 MOUNT THE NAMEPLATE ON THE UNIT
Select your company nameplate (Venmar or vänEE) and snap it on the unit door. Discard the other
nameplate.
2.5 HOW TO HANG THE UNIT
Use the 4 chains and springs in the hardware pack provided with the unit. According to your needs, you can install the unit either in vertical
or horizontal position.
CAUTION
Remove the cardboard strip inside the unit.
WARNING
To avoid risk of suffocation, discard the plastic bag wrapping the unit.

2.5 HOW TO HANG THE UNIT (CONT’D)
•
Turn the switch knob to OFF position in order to unlock the door. Unlatch the door and open it.
NOTE: If preferred, the door can be removed. First, remove the stopper (A) located on the
right side of the door hinge, then, slide the door out of its hinge.
• Using a screwdriver, remove the 2 retaining screws of the front plate and carefully remove
the front plate from the unit.
• Insert the 4 hooks in the square holes and fix them to the unit using 4 screws #8 - 32 x 3/4”.
NOTE: If an optional wall controll has to be installed, go to Section 4.0 on pages 20 to 22.
If not, continue the installation.
• Reinstall the front plate, the door and the door stopper.
• Hang the unit to the floor joist, using 4 #8 x 1 1/2” screws, 4 chains and 4 spings.

2.6 PLANNING OF THE DUCTWORK
• Follow the instructions in Section 2.7 below to determine the appropriate duct diameters for your system. Do not use branch lines
smaller than 6”ø (152 mm) diameter.
• Do not use wall cavities as ducts.
• Keep it simple. Plan for a minimum of bends and joints.
• Do not ventilate crawl spaces or cold rooms.
• If the house has two floors or more, be sure to plan for at least one exhaust register at the highest lived-in level of the house.
2.7 CALCULATING THE DUCT SIZE
Use the table below to ensure that the ducts you intend to install will be carrying air flows around the recommended values.
Avoid installing ducts that will have to carry air flows near the maximum values and never install a duct if its airflow exceed
the maximum value.
NOTE: Examples 2.7.1 and 2.7.2 use imperial measures. The same calculation applies to metric measures.
2.7.1 EXAMPLE OF CALCULATION:
Problem: My installation requires two exhaust registers (one for the kitchen, one for the living room). I will connect these registers to
a main duct which will connect to the unit (high speed performance value of 320 cfm). What size of duct should I use for
the main exhaust duct and for the two end branches leading to the registers? (See illustration below.)
Solution: Simplified method.
(For a more detailed method of calculating duct size refer to the
ASHRAE or HRAI HANDBOOK).
Main duct:
Table on page 8 indicates a 8” Ø: recommended air flow: 260 cfm; maximum
air flow: 380 cfm.The high speed air flow of 320 cfm is close enough to the recommended
value (260) and far enough of the maximum value (380). Therefore a 8ӯ duct or larger
is an appropriate choice for the main e
xhaust duct.
End br
anches: Each end branch will have to transport an air flow of 160 cfm
(320 divided by 2). Table on page 8 indicates a 6ӯ: recommended air flow: 120 cfm;
maximum air flow: 180 cfm. The high speed air flow of 160 cfm is close enough to the
recommended value (120) and far enough of the maximum value (180). Therefore a 6ӯ
duct or larger is an appropriate choice for the 2 end br
anches.
2.7.2 EXAMPLE OF A DESIGN FOR A FULLY DUCTED SYSTEM FOR A UNIT HAVING A HIGH SPEED PERFORMANCE OF 320 CFM.
CAUTION
Do not attempt to recover the exhaust air from a dryer or a range hood. This would cause clogging of the filters.
