WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK,

OR INJURY TO PERSONS, OBSERVE THE FOLLOW-

ING:

1. Use this unit only in the manner intended by the manu-

facturer. If you have questions, contact the manufac-

turer at the address or telephone number listed below

the warranty.

servicepanelandlocktheservicedisconnectingmeans

to prevent power from being switched on accidentally.

Whentheservicedisconnectingmeanscannotbelocked,

securely fasten a prominent warning device, such as a

tag, to the service panel.

3. Installation work and electrical wiring must be done by

qualified person(s) in accordance with all applicable

codes and standards, including fire-rated construction

codes and standards.

4. Sufficient air is needed for proper combustion and

exhausing of gases through the flue (chimney) of fuel

burning equipment to prevent backdrafting. Follow the

heating equipment manufacturer’s guideline and safety

standards such as those published by the National Fire

Protection Association (NFPA), and the American Soci-

etyforHeating,RefrigerationandAirConditioningEngi-

neers (ASHRAE), and the local code authorities.

5. When cutting or drilling into wall or ceiling, do not

damage electrical wiring and other hidden utilities.

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

7. This unit must be grounded.

PLAN THE INSTALLATION

Adequate ventilation requires that both intermittent and

continuous contamination be controlled.

Intermittent ventilation must be provided in the bathroom

andkitchen.Thebathroomrequires8airchangesperhour.

(Multiplybathroomsq.footage by 1.1forproperfan sizing)

The kitchen requires a minimum of 150 CFM capacity (71

l/s) when a ducted range hood is used. If a kitchen fan is

used, determine fan capacity by multiplying the room's sq.

footageby2.Allarerunintermittentlytocontrolpollutionat

the source.

Continuous ventilation, while the house is occupied, pro-

vides the flow of fresh air for good indoor air quality.

This ventilator is intended to for continuous operation,

supplying fresh air to the entire house.

The number of inlet vents depends on the floor plan.

Consider the rooms/areas through which fresh air should

flow toward the exhaust diffuser(s).

Vents should be located in outside walls, preferably near

the ceiling and approximately the same distance from a

diffuser. Vents should be separated from diffusers far

enough to allow fresh air to mix with room air before being

exhausted.

VENTILATOR

The ventilator exhausts stale air. There are normally suffi-

cient natural intake openings into a dwelling to admit fresh

outsideairtobedrawnintoreplacethe stale air. Forbetter

control, fresh air inlets may be used.
