2.
Ensure duct joints and exterior penetrations are sealed with caulk or other similar
material to create an air-tight path to minimize building heat loss or gain and to reduce
the potential for condensation. Place/wrap insulation around duct and/or fan to in order
to minimize possible condensation buildup within the duct, as well as building heat loss
or gain
(Figure 9).
SECTION 5
Wiring
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE STARTING INSTALLATION.
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.
1.
Run wiring from an approved wall switch carrying the appropriate rating. One neutral
(white), one ground (green or bare copper), and one hot (black lead connected to
the switch). Secure the electrical wires to the housing with an approved electrical
connector. Make sure you leave enough wiring in the box to make the connection to the
fan’s receptacle.
2.
From where you have access to inside the fan’s junction box, connect the White wire
from the house to the White wire from the fan’s receptacle. Connect the Black wire from
the wall switch to the Black wire from the fan’s receptacle. Connect the ground wire
from the house to the Green wire from the fan’s receptacle
(Figure 10)
. Use approved
methods for all connections.

SECTION 6
Completing the Installation
1.
Use a sealant appropriate for contact with the building materials present and for the
temperature requirements of the installation to prevent air leakage from unconditioned
spaces is recommended. If gaps between unit housing and ceiling are great, additional
material (backing rod, ceiling material) may be required.
NOTE:
This fan is rated for direct insulation contact (Type IC) and it is recommended that this fan
be completely covered by insulation in order to reduce heat loss or gain to unconditioned space.
2.
Reinstall the fan’s wire compartment cover. Rotate the blower wheel by hand to
ensure it spins freely. Plug the fan’s quick connect motor cord into the receptacle.
This cord will only fit one way into the receptacle
(Figure 11).
NOTE:
If using this fan to meet ASHRAE 62.2 requirements, locate the label inside the fan
housing and fill in the appropriate information.
3.
Install the grill by squeezing the two ends of the springs together and installing them up
into the slots of the fan’s housing. Push the grill up into position
(Figure 12).
4.
Restore power and test your installation.
SECTION 7
Use and Care
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE SERVICING THE UNIT.
1.
Cleaning the Grill:
Remove grill and use a mild detergent, such as dishwashing liquid,
and dry with a soft cloth. NEVER USE ANY ABRASIVE PADS OR SCOURING POWDERS.
Completely dry grill before reinstalling. Refer to instructions in
Section 6
Finishing the
Installation
, to reinstall grill.
2.
Cleaning the Fan Assembly:
Unplug the motor cord from receptacle. Wipe all parts
with a dry cloth or gently vacuum the fan. NEVER IMMERSE ELECTRICAL PARTS IN
WATER. Plug the motor cord back in and restore power.
