a) Installation work and electrical wiring must be done by qualified
person(s) in accordance with all applicable codes and standards,
including fire-related construction.
b) Sufficient air is needed for proper combustion and exhausting of

and safety standards such as those published by the National Fire
Protection Association (NFPA) and the American Society for Heating,
Refrigeration, and Air Conditioning Engineers (ASHRAE), and the local
code authorities.

INSTALLATION INSTRUCTIONS
CAUTION: MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE STARTING INSTALLATION.
CAUTION: MAKE SURE THE MAIN UNIT IS INSTALLED
ACCORDING TO ALL INSTRUCTIONS INCLUDED WITH THE UNIT.
WARNING: THIS UNIT IS TO BE USED ONLY WITH QUFRESH BY
ENVIROWISE MODELS CAPABLY OF ACCEPTING THE 24V TRANSFORMER.
SECTION 1
Preparing the Fan
1. Unpack unit from the carton and confirm that all pieces are present. In addition to the
motorized damper you should have:
1 - 24V transformer
1 - Plastic Bushing
1 - Cable Tie
1 - Instruction/Safety Sheet
SECTION 2
Installation
1. Install the motorized damper to the outlet (discharge) side of the unit using 6" rigid
ducting and seal with appropriately rated tape. Use screws or suitable clamps to secure
in place. If any additional ducting will be installed to the outlet side of the motorized
damper (as with an inline installation) repeat the same procedure as above (Figure 1).

CAUTION:
ALL ELECTRICAL
CONNECTIONS MUST BE MADE IN
ACCORDANCE WITH LOCAL CODES,
ORDINANCES, OR NATIONAL ELECTRICAL
CODE. IF YOU ARE UNFAMILIAR WITH
METHODS OF INSTALLING ELECTRICAL
WIRING, SECURE THE SERVICES OF A
QUALIFIED ELECTRICIAN.
4. Remove the plastic cover from the
receptacle inside the main unit housing.
Plug the included 24VAC transformer
into the receptacle and run the lead
wires to the motorize damper. Make the
electrical connections to the motorized
damper by connecting the wires from the
damper to the pre installed ends (Figure
3).
NOTE: Make sure the wires running to the
transformer are not in the direct path of the
incoming air. This could cause a “rattling” noise.
Use a small piece of ducting tape to secure the
wires to the fan housing if necessary. If your
unit includes a 24V Relay Controller, the wires
can be fastened to the side of the control box
using the included wire tie. To do so, slide the
wire tie into the slot of the holder on the back
side of the relay box. To access to the holder,
this will need to be done before the relay box is
installed.
5. Close the access panel and reinstall the
screw holding the access panel in place.
6. Restore power and test your installation.
SECTION 3
Operation
1. The receptacle inside the unit will be energized anytime the fan is running. This will in
turn open the motorized damper. When the unit stops running, the damper will close.
