are connected. Disconnect the solar panels from the control unit before

doing any maintenance to the blower.

11. Stay alert. Watch what you are doing, use common sense. Do not operate

any tool when you are tired.

12. Check for damaged parts. Before using any tool, any part that appears

damaged should be carefully checked to determine that it will operate

properly and perform its intended function. Check for any broken parts or

mounting ﬁxtures; and any other condition that may affect proper operation.

Any part that is damaged should be properly repaired or replaced by a

qualiﬁed technician. Do not use the tool if any switch does not turn On and

Off properly.

13. Guard against electric shock. Prevent body contact with grounded

surfaces such as pipes, radiators, ranges, and refrigerator enclosures.

Assembly and Operation

These solar panels produce electricity when in the presence of sunlight. The

amount of electricity produced increases as the sunlight becomes stronger. Less

power is produced in less sunlight, but these panels will generate electricity even

on cloudy days.

The enclosed mounting frame is designed to hold the solar panels at an angle to

increase the amount of surface directly facing the sun. Adjust the position of the

mounting frame to maximize exposure to sunlight.

These solar panels are designed to power an exhaust fan, which is ideal for green

houses, sheds, boats or house vents.

Assemble the solar panel frame.

1. Press the Left and Right Triangle

Frames into slots 1 and 3 on both

ends of the Top Link Bar and Bottom

Link bar, as shown in the diagram.

2. Push the Top Link Bar down to Slot 2

to lock the frame assembly.

3. Position the assembled frame in a

location that the Solar Panels will

directly face the Sun. The assembly

should face the South for maximum

exposure and have no obstructions in

front of it.The mounting surface must

be level, well constructed and capable

of supporting the frame assembly and

Solar Panels. The location should

be out of the way of passersby and

protected from damage.

4. Secure the frame assembly using

hardware (not supplied) through the

four holes in the bottom of the Left and

Right Triangle Frames.

5. Carefully place each Solar Panel on

the front of the frame assembly, so

the bottom of each Solar Panel ﬁts into the slot of the bottom of the frame

assembly.

6. Lock the two eye hooks on the backs of the Solar Panels to the bolts on the

Top Link Bar to secure the Solar Panels in place.

Attach the AdjustableTemperature Control Unit.

Keyhole hanger

1. Mount the Adjustable Temperature Control

Unit to a secure location using the keyhole

hanger. The Control Unit must be mounted

inside the building for the temperature control

to function.

2. Attach the ring connectors from the Solar

Panels to the contacts on the Control Unit

marked “Solar”. Attach the power cords to

the proper polarity. There should be two ring

connectors on each terminal.

Attach the Exhaust Fan.

Mount the Exhaust Fan in your building using

hardware (not supplied) in the holes drilled in

the edge of the fan. Be sure the fan is mounted securely, is protected from water

and other local materials which may damage it. A protective grid (not supplied)

must be installed on both sides of the fan to prevent injury.

CAUTION: The Fan may begin operating without notice whenever there is

sufﬁcient electricity in the system from either the Solar Panels or the battery.

Attach an optional 12V battery.

1. It is recommended that a 12V 20 Ah battery (not included) be installed to store

spare electricity generated during the day so the fan can continue to operate

after daylight hours.

2. Battery Connector (jumper cables) are provided. Connect the RED cable to

the positive (+) connector of the Control Unit and the positive (+) pole of the

battery. Connect the BLACK cable to the negative (-) connector of the Control

Unit and the negative (-) pole of the battery.

CAUTION: The battery must be rated for 12V and at least 20 Amp-hours. A

lesser battery will be damaged if attached to this system.

CAUTION: If the fan is disconnected, also disconnect the battery.The battery

may be damaged if left connected to a solar panel system without the

fan operating.

Setting the Adjustable Temperature Control Unit.

1. Adjust the desired temperature by rotating the dial on the front to the desired

temperature. When the ambient temperature goes above the desired

temperature, the fan will go on, the fan will go off when the temperature falls

below the setting. The temperature range is 59° to 140° F (15° to 60° C).

2. The Control Unit has a built in regulator that will prevent battery discharge if

the battery level is less than 10.5 Volts or overcharge if the battery charge is

over 14.5 Volts.

Maintenance

NOTE: These panels will produce electricity on a continual basis depending on

the amount of sunlight they receive, as long as they have a completed circuit

and the temperature control is adjusted to the ambient temperature.

1. Be aware that the exhaust fan may operate automatically whenever a solar

panel is exposed to sunlight or there is charge in the battery.

2. Some batteries will be damaged if they are continuously charged. Do not

leave the fan disconnected and any battery attached to this system. Although

the control unit has a built-in regulator, it may not protect the battery in all

situations.

3. Keep the solar panels clean. Wipe them occasionally using a damp cloth

with mild detergent. Do not use abrasives. Dirt on the glass will reduce the

capacity of the panels to receive sunlight.

4. Periodically check the wiring, mounting and status of the system. Repair any

unsafe condition immediately.

5. If the unit stops working even in bright sunlight, check the fuse. Open

the fuse container on the side of the Control Unit by turning the fuse cap

counterclockwise. If the fuse wire is broken, replace the fuse with an identical

3 amp fuse. Replace and tighten the fuse cap.

Electrical Power Sources Connected in Series and Parallel.

Solar Panels, batteries and other power sources may be connected in a circuit in

“Series” or in “Parallel”. When connected in series, the voltage is combined while

the Amperage is unchanged. When connected in parallel, the voltage remains

unchanged while the amperage is combined.

In series, the voltage is combined while the amperage is unchanged.

In parallel, the voltage remains unchanged while the amperage is combined.
