Preinstallation

WARNING: FIRE OR ELECTRICAL SHOCK HAZARD. Failure to obey these warnings could result in death or serious injury.

• Shut off the gas supply, disconnect the 115 VAC power from the RV, and disconnect the positive (+) 12 VDC terminal from the supply battery before drilling or cutting into the RV.
• Make sure there are no obstacles such as wires or pipes inside the RV’s roof or exterior wall.
• Provide grounding in compliance with all applicable electrical codes.
• Read this entire section before beginning the installation.

This section describes the preparations to complete prior to installing the fan.

Preparing the RV Roof or Wall Opening
This section describes how to prepare the RV roof or wall opening.

Using an Existing Fan Opening
I If the RV does not have an existing fan, skip to “Making a New Opening” on page 8.

1. Shut off the gas supply, disconnect the 115 VAC power from the RV, and disconnect the positive (+) 12 VDC terminal from the supply battery.

2. Unscrew and remove the existing fan.

3. Remove any caulking compound around the roof or wall opening. A clean surface offers a better seal. Consult your RV owner’s manual for cleaning recommendations.

4. Use sealant to seal any screw holes or seams.

5. Measure the opening (review “Fan Cut-out Dimensions” on page 4). If the roof opening is within specifications, skip to “Assessing the Trim Garnish” on page 9.

6. If the opening needs to be resized, proceed to “Making a New Opening” on page 8:

   • If the opening exceeds 14.4 x 14.4 in.
     (366 x 366 mm), it will be necessary to reduce the size of the opening.

   • If the opening is less than 14.1 x 14.1 in.
     (358 x 358 mm), it ill be necessary to enlarge the opening.

Making a New Opening
I If the roof or wall has an existing fan opening, see “Using an Existing Fan Opening” on page 8.

1. Carefully mark the required opening.

2. Incorrect installation

3. Correct installation

4. Make sure the new opening does not compromise the structural integrity of the roof or wall.

   • Do not cut the roof structure, rafters, or wall studs.
   • The rafters should remain supported by a cross beam.
   • The opening should be between the rafters or wall studs.

5. Carefully cut the required opening.

Framing the Roof or Wall Opening
If the roof is corrugated or not level, use this section to create a level platform or contact a qualified service professional.

1. 1. 0.8 in.  

   (25 mm)

2. 0.3 in. (6 mm) Opening for the Power Supply Wiring

Build a frame for the fan opening to provide a level platform for securing the mounting flange to the roof.
Leave access for the power supply wiring to pass into the interior through the frame.

Assessing the Trim Garnish

1. Determine the length, width, and thickness or depth of the roof or wall opening where the new fan will be installed.

2. Confirm you have the correct trim garnish for the depth of the opening. See “Trim Garnish Dimensions” on page 5.

3. Required Trim Garnish Height

4. Excess Trim Garnish to Remove

5. Garnish

6. Score Lines

7. Use a utility knife to adjust the size of the trim garnish to the correct height, if necessary.

a. Use a straight edge and a pen to mark horizontally around all four sides from the top edge. Score the marked lines.
b. Cut from the top edge of the corners at a 45-degree angle down to the scoreline, then carefully break the excess plastic away from the trim garnish.

Connecting the Power
If you are replacing an existing fan, use the existing wiring only if it meets the Recreation Vehicle Industry Association’s 16 AWG wiring and location requirements.

This section describes how to connect the fan to a 12 VDC power source.

1. Locate the nearest 12 VDC power source wiring.

2. To avoid blowing the fuse, test the power source wiring for polarity.
   a. Turn on the 12 VDC power or battery.
   b. Using a multimeter, touch the red lead to the positive source. At the same time, touch the black lead to the neutral or negative wire.

   • A correct polarity will display +12 or more volts.
   • If incorrect, the multimeter will display -12 volts or more.
     c. Turn off the 12 VDC power or battery.
   1. 6 in. (152 mm) minimum

3. Route the power source wiring to the roof or wall opening. Add an additional 15 in. (381 mm) of wire, to ensure an easy connection to the fan.

4. White Fan Wire (Neutral or Ground)

5. w Butt-slice Connector

6. Power Source Wiring (Neutral or Ground)

7. Power Source Wiring (Positive or Fused)

8. Black Fan Wire (Positive or Fused)

9. Use the connectors to connect the fan’s:
   a. black wire to the positive 12 VDC power source wire.
   b. white wire to the neutral or ground.

10. Crimp the connector ends to secure the connection.

Installation

WARNING: ELECTRIC SHOCK HAZARD. Turn the power off before performing any electrical installation or maintenance activities. Failure to obey this warning could result in death or serious injury.

NOTICE: Always use sealant on (clean) parts and surfaces where wiring or fasteners enter the RV’s walls, roof, or floor. Otherwise water damage could occur.
If using sealant for rubber roofs, use an EPDM- compatible roof sealant.
This section provides information on mounting the fan, installing the garnish, and connecting the power.

Mounting the Fan

This section describes the two installation options for your fan.

• A vent mount installation is the standard, recommended method for most fans. See “Vent Mount” on page 10.
• • A clamp-fan mount is recommended only for a roof or wall that is less than 4 in. (102 mm) thick and without a solid substrate to support a rooftop screw installation. See “Clamp-Fan Mount” on page 11.
• Confirm the height of the trim garnish is correct for the thickness of your roof or wall. See “Trim Garnish Dimensions” on page 5.

Vent Mount
This section describes how to install a fan using the vent mount method.

1. Sealant

2. 8 x 1 in. PHPH T/S Zinc Screws

3. Flange
4. Gasket

• Line the outside of the opening with sealant, or place a gasket on the opening and apply the sealant around the outer edge of the gasket.
  No sealant should be placed on the top or bottom of the gasket.

• Position the fan over the opening, making sure the sealant and/or gasket is “sandwiched” between the bottom of the mounting flange and the roof opening.

  • When positioning the fan on the roof, the lid hinge should be closest to and aligned with the front of the RV.
  • If positioning the fan on the side of the RV (vertically), the lid hinge should be closest to and parallel with the roof line.

• Use the screws to secure the fan to the RV.
  Torque all screws equally and do not overtighten.

• Apply sealant over the screw heads and at the mounting flange where it meets the roof or side.

  1. Fan
  2. Trim Garnish
  3. Screws

• From the interior of the RV, secure the garnish to the roof using the appropriate screw for the garnish size.
  See “Trim Garnish Dimensions” on page 5.

Torque all screws equally and do not overtighten.

Clamp-Fan Mount
This section describes how to install a fan using the clamp-fan method.

Some fans are available in a “clamp fan” configuration for roof or wall openings with a thickness less than 4 in. (102 mm). The shorter trim garnish for a clamp-fan mount is designed to secure the fan with screws into the fan base from inside the RV and to trim the cut-out.

1. Flange
2. Fan Hinge
3. Sealant

• Run a double-bead of sealant around the outside of the roof or wall opening.
  Do not use putty tape, butyl, or gaskets for clamp-fan mounts.

• Position the fan on the sealant and press down.

• Apply sealant over the screw holes and at the mounting flange where it meets the roof or side.
  Failure to seal the screw holes and flange could lead to water damage.

Operation

NOTICE: Do not leave the dome open and unattended for extended periods of time. High winds or other unusual conditions may result in leakage and/or serious damage. Use of the fan in inclement weather or other adverse conditions could cause property damage.

The source of airflow is determined by the window(s) or door(s) opened. For best results, close all roof vents and partially open the window or door that is the greatest distance from the fan.

This section contains information about operating the fan according to the model.
