GENERAL SAFETY INFORMATION

(Continued)

CAUTION: FOR GENERAL VENTILATING USE ONLY. DO NOT USE TO EXHAUST HAZARDOUS OR EXPLOSIVE MATERIALS AND VAPORS.

6.When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.

7.Ducted fans must always be vented to the outdoors.

8.This unit must be grounded.

9.To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off power unit.

WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, DO NOT USE THIS FAN WITH ANY SOLID-STATE SPEED CONTROL DEVICE.

10.Acceptable for use over a bathtub or shower when installed in a GFCI protected branch circuit.

11.NEVER place a switch where it can be reached from a tub or shower.

WARNING: DO NOT USE IN KITCHENS

INSTALLATION INSTRUCTIONS

CAUTION: MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL BEFORE STARTING INSTALLATION.

SECTION 1 Preparing the Exhaust Fan

1.Unpack fan from the carton and confirm that all pieces are present. In addition to the exhaust fan you should have:

1- Grill

1- Damper Assembly (attached)

1- Instruction/Safety Sheet

2.Remove the fan’s venturi assembly, which is secured in place with one screw through the venturi (Figure 1). This is a captive screw and will stay installed in the venturi. Keep the venturi assembly and the grill in the carton until needed so they do not get damaged or lost.

Figure 1

3.Choose the location for your fan. To ensure the best air and sound performance, it is recommended that the length of ducting and the number of elbows

be kept to a minimum, and that insulated hard ducting be used. Larger duct sizes will reduce noise and airflow restrictions.

4.Select the most convenient electrical knockout and remove using a straight- blade screw driver (Figure 2).

Figure 2

SECTION 2

New Construction

1.Using the gauge on the fan’s housing (Figure 3), line up housing so that it will be flush with the finished ceiling or wall. Position the fan so that the tabs rest flat against the joist or stud and secure with four nails (not provided) to ensure proper installation.

SECTION 3

Existing Construction

1.Position housing against the joist or stud and trace an outline of the housing onto the ceiling/wall material (Figure 4). Set housing aside and cut opening, being careful not to cut or damage any electrical or other hidden utilities. Place housing next to the joist or stud and insure that it is flush with the finished ceiling. Secure with four nails (not provided) to ensure proper installation (Figure 3).

SECTION 4

Ducting

CAUTION: ALL DUCTING MUST COMPLY WITH LOCAL AND NATIONAL BUILDING CODES.

1.Connect the ducting to the fan’s duct collar (Figure 5). Secure in place using tape or screw clamp. Always duct the fan to the outside through a wall or roof cap.

Figure 5

NOTE: If damper detaches from unit, reattach by snapping the collar back onto the unit. It is designed to only fit one way.
