VENTILATION FAN

a). Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer.

b). Before servicing or cleaning unit, switch power off at service panel and lock the service disconnecting means to prevent power from being switched on

accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to the service panel.

c). Installation work and electrical wiring must be done by a qualified person(s) in accordance with all applicable codes and standards, including

fire-rated construction codes and standards.

d). Sufficient air is needed for proper combustion and exhausting 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 Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.

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

f). Ducted fans must always be vented to the outdoors.

g). Acceptable for use over a tub or shower when connected to a GFCI (Ground Fault Circuit Interrupter) - protected branch

circuit (ceiling installation only).

h). This unit must be grounded.

i). Not for Use in Kitchens.

j). To reduce risk of fire and to properly exhaust air, be sure to duct air outside – Do not vent exhaust air into spaces within walls or ceilings or into

attics,crawl spaces, or garages.

k). WARNING: To Reduce The Risk Of Fire Or Electric Shock, Do Not Use This Fan With Any Solid-State Speed Control Device.

See “Connect Wiring” for details.

The control box, located inside the fan housing, has three separate adjustments:

(1) the low airflow knob adjusts the lower airflow from 30 CFM up to the air flow rate of the high fan speed determined by the toggle switch setting.

The low speed is de-activated when set between OFF-30 CFM (factory set to OFF).

(2) (For SL100-3H and SL100-3HM) the humidity sensor knob set user-adjustable setpoint. Factory set to 80% (Ambient temperature of 25 ℃).

(Only for SL100-3)

The time delay knob is adjustable from 3 to 30 minutes and will switch the fan to the low speed setting after the switch

II is turned off for the set period of time

The time delay setting is de-activated when set between OFF-3 mins (factory set to OFF).

(3) The toggle switch will adjust the upper fan speed setting from 50 to 100 CFM. (factory set to 100CFM).

MOTION SENSOR OPERATION for

SL100-3HM

Plug the motion sensing grille into the fan control module and when powered on, the fan

will automatically start sensing motion.

Turn on the switch to activate sensor and continuous ventilation system. The fan will run

continuously at the pre-set low speed.

When motion is detected, the fan speed increases to high speed.

When the person exits the area, the fan remains working at high speed until the delay time

has passed (20 minutes).

After the time delay, the fan speed is reduced to the continuous ventilation rate.

Installation distance: 5 to 7 feet.

Sensing range is within the cone angle of 90°.

1. Do not use in a cooking area. 2. Two ways to connect ductwork to a factory-shipped unit.

To Turn Fan ON

Turn the switch I(according to the following “CONNECT ELECTRICAL WIRING” ) ON.

• Fan will run at the certified airflow rate if the switch II is ON.

• Fan will run at the user-adjustable airflow rate if the switch II is OFF.

To Use Fan Time Delay Airflow Rate Change

1. Turn the switch ION.

2. Turn the switch II ON - fan will run at the certified airflow rate.

3. When the switch II is turned OFF, fan will continue to run at the certified airflow rate until the time delay has elapsed (for SL100-3, the delay time is

user-adjustable from 3-30mins; for SL100-3H and SL100-3HM, the delay time is 20 mins), and then will automatically change to the user-adjustable

airflow rate.

To Turn Fan OFF

Turn the switch IOFF

For SL100-3H and SL100-3HM

The fan will run continuously at a low speed (adjustable by low airflow knob) and automatically boost up to high speed when either of these conditions is

detected: a) Humidity above a user-adjustable setpoint (30%-80% relative humidity). b) rapid increases in humidity. After delay timer (20 minutes)

returns fan to the default low speed. Humidity sensor description accroding to “HUMIDITY SENSOR OPERATION” and “SENSITIVITY ADJUSTMENT”.

HUMIDITY SENSOR OPERATION (For

SL100-3H

and SL100-3HM)

The humidity-sensing fan uses a sophisticated humidity sensor that responds to: (a) rapid increases in humidity or (b) humidity above a user-adjustable

set-point (30%-80% relative humidity). The fan will run continuously at a pre-set lower level (set by Low airflow knob) and automatically boost up to

certified airflow rate when environmental conditions change. If the fan continuously responds to changing environmental conditions, “H” (means

“humidity”) adjustment may- be required.

SENSITIVITY ADJUSTMENT (For

SL100-3H

and SL100-3HM)

The “H” has been factory set for most shower applications. However, if the fan is in a tub area or is being used for dampness control, the “H” may need

to be increased toward maximum. If the control is responding too often to changing environmental conditions, movement toward minimum, “H” may be

required.

To adjust the “H”:

1. Disconnect power at service entrance.

2. Through the grille, locate the slot marked “H”.

3. Carefully rotate the “H” adjustment toward maximum or minimum.

4. Turn on power and check operation by turning on the shower or other humidity source until the fan turns on.

5. Repeat above steps if necessary.

When the temperature changes, humidity sensor values will have deviation.

3. Mount with Hanger Bars

Slide one hanger bar into the channel on the housing and adjust as

needed to fit between framing. Hold housing in place so that the housing

contacts the bottom of the joist, Screw housing to joist through the hole A

and hole B. Screw the hanger bar onto the other side of joist through its

hole.

to fit I-joist. Hold housing in place so that the housing contacts the bottom

of joist. Screw housing to joist through the hole A and hole B. Screw the

hanger bar onto the joist through its hole.

6. INSTALL ROUND DUCTWORK

Connect the round ductwork (not included) to the damper/duct connector, and run

the ductwork to a roof or wall cap (not included).

Using tape (not included), secure all the ductwork connections so that they are air

tight.The ducting from this fan to the outside of building has a strong effect on the air

flow, noise and energy use of the fan. Use the shortest, straightest duct routing

possible for best performance, and avoid installing the fan with smaller ducts than

recommended. Insulation around the ducts can reduce energy loss and inhibit mold

growth. Fans installed with existing ducts may not achieve their rated air flow.

Run 120V AC house wiring to the location of the fan. Use only UL-approved connectors (not included) to attach the house wiring to the

wiring plate. Refer to the wiring diagram, and connect the wires as shown.

CONNECT ELECTRICAL WIRING

Install ceiling material to complete the ceiling construction. Then, cut around the fan

housing.

To attach the grille assembly to the fan housing, pinch the grille springs on the sides

of the grille assembly, and position the grille into the housing with the grille springs in

the appropriate slots. Push the grille assembly towards the ceiling to secure.
