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

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.
