4.3 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. 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 5.0 on pages 29 to 31. If not, continue the installation.
• Reinstall the front plate and close the door.
• Hang the unit to the floor joist, using 4 #8 x 1 1/2” screws, 4 chains and
4 spings. See following illustration.
4.4 PLANNING OF THE DUCTWORK
• Keep it simple. Plan for a minimum of bends and joints.
• Keep the length of outside insulated duct to a minimum (not for HEPA 1000).
• Do not ventilate crawl spaces or cold rooms. Do not attempt to recover the
exhaust air from a dryer or a range hood. This would cause clogging of the
filters and recovery module (if applicable).
• If the house has two floors or more, be sure to plan for at least one exhaust
register on the highest lived-in level.
