Installation Guide

PART 4 Electrical Connection

IMPORTANT: Copy this page and the next 2 pages to your electrical installer.

WARNING! Ensure that the power supply is disconnected before proceeding. Verify that the power supply

matches the ratings found on the appliance data label before proceeding. The complete appliance must be

properly grounded at all times when electrical power is applied. Do not ground the appliance with the neutral

(white) house supply wire. A separate ground wire must be utilized. Failure to complete electrical connections

properly may result in damaged or non-functional systems. Follow instructions carefully to ensure proper

installation.

It is the owner’s responsibility to ensure that a qualified person performs the electrical connection of this appliance.

The electrical installation, including minimum supply wire size, must comply with the National Electric Code

ANSI/NFPA 70-1990 (or latest revision) and local codes and ordinances. A copy of this standard may be obtained

from: National Fire Protection Association, 1 Batterymarch Park, Quincy, Massachusetts 02269-9101

INSTRUCTIONS: A 15 to 20 amp electrical service is recommended for proper electrical supply. Before

determining, calculate amp ratings based on the product label found on the liner and the ventilator. Always observe

local building codes. Always use a dedicated circuit. Line load is calculated by adding the amperage of the

halogen lights to the rated amperage of the ventilator (either in-line or roof top). If the ventilator is rated in watts

rather than amps, divide the watts by 120 and this will give you the amperage rating. The Trade-Wind

liner,

without the internal motor, is supplied with a 6.0 amp variable speed fan control. Make sure the rated amperage on

the ventilator does not exceed 6.0 amps.

CAUTION: The neutral wire (usually white) for the blower/motor must connect to the same neutral wire

that comes from the electrical panel to the liner. It is recommended to run a white neutral wire from the liner’s white

neutral wire along the same path as the red wire from the liner’s variable speed control to the blower/motor.

Variable-Speed Control Wiring Details (for remote blowers, usually “in-line” blowers)

Black

120 volt AC from electrical panel (usually black) to liner

White

Neutral from electrical panel (white) to liner

Green

Ground from electrical panel (usually green) to liner

Red

120 volt AC variable control from liner to 120 volt AC of variable speed ventilator

CAUTION: Do NOT connect this wire to a 3-speed blower.
