HAZARDOUS DUST. Dust exposure may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material, and always wear a NIOSH-approved respirator to reduce your risk.

DUST ALLERGIES. Dust from certain woods may cause an allergic reaction in people and animals. Make sure you know what type of wood dust you will be exposed to in case of an allergic reaction.

POWER DISCONNECT. Turn switch OFF, disconnect air filter from power supply, and allow impeller to come to a complete stop before doing any cleaning, maintenance, or service.

SUSPENDED DUST PARTICLES AND IGNITION

SOURCES. To reduce risk of death or injury caused by explosions or fires, DO NOT operate filter in areas where these risks are high, including, but not limited to, spaces near pilot lights, open flames, or other ignition sources.

MOUNTING. To reduce risk of injuries due to filter falling, secure it to load-bearing joists or wall studs that can support its weight. Do not mount unit only to sheet rock, pressboard, paneling, or honeycomb ceiling panels with expansion-type fasteners, which can easily tear out.

Model G9956 (Mfg. Since 8/15)

SECTION 2: POWER SUPPLY

Availability

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrician or qualified service personnel in accordance with all applicable codes and standards.

Electrocution, fire, shock, or equipment damage may occur if machine is not properly grounded and connected to power supply.

Full-Load Current Rating

The full-load current rating is the amperage a machine draws at 100% of the rated output power.

On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

Full-Load Current Rating at 120V ....... 3 Amps

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit.

To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the specified circuit requirements.

Serious injury could occur if you connect machine to power before completing setup process. DO NOT connect to power until instructed later in this manual.

Circuit Requirements

This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following requirements:

Nominal Voltage ........................................ 120V

Cycle ..........................................................60 Hz

Phase ........................................... Single-Phase

Power Supply Circuit ......................... 15 Amps

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power supply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

For your own safety and protection of property, consult an electrician if you are unsure about wiring practices or electrical codes in your area.

Note: Circuit requirements in this manual apply to a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, consult an electrician or qualified service personnel to ensure circuit is properly sized for safe operation.

-9Model G9956 (Mfg. Since 8/15)

Grounding & Plug Requirements

This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current.

This machine is equipped with a power cord that has an equipment-grounding wire and a grounding plug. Only insert plug into a matching receptacle

(outlet) that is properly installed and grounded in accordance with all local codes and ordinances.

DO NOT modify the provided plug!

5-15 RECEPTACLE

Grounding Prong

5-15 PLUG

Neutral Hot

Figure 2. Typical 5-15 plug and receptacle.

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is necessary, do not connect the equipment-grounding wire to a live (current carrying) terminal.

Check with a qualified electrician or service personnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded. If you ever notice that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with a new one.

Extension Cords

We do not recommend using an extension cord with this machine. If you must use an extension cord, only use it if absolutely necessary and only on a temporary basis.

Extension cords cause voltage drop, which can damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller

(higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must be in good condition and contain a ground wire and matching plug/receptacle. Additionally, it must meet the following size requirements:

Minimum Gauge Size ...........................16 AWG

Maximum Length (Shorter is Better).......50 ft.

SHOCK HAZARD!

Two-prong outlets do not meet the grounding requirements for this machine. Do not modify or use an adapter on the plug provided—if it will not fit the outlet, have a qualified electrician install the proper outlet with a verified ground.

Test Run

Before you install the model G9956, bench-test the unit to make sure it runs properly.

Note: Do not be alarmed if you notice a small amount of vibration during the Test Run. It is normal for all air filters to produce a small amount of vibration during operation. This vibration is much more noticeable when operating on a hard surface, such as a workbench, compared to when operating in a suspended position, as designed.

If, during the test run, you cannot easily locate the source of an unusual noise or vibration, stop using the machine immediately, disconnect it from power, then review the Troubleshooting on

Page 20.

If you still cannot remedy a problem, contact our

Tech Support at (570) 546-9663 for assistance.

10. Push the ON/HR button on the remote control to turn the air filter ON, then push OFF to turn the filter OFF.

Model G9956 (Mfg. Since 8/15)

Site Planning

Site planning is an important step to maximize the effectiveness of the hanging air filter. Air circulation must be thought out and all obstructions to the air path considered.

Think of air circulation in terms of the circular motion of the air before and after the air filter. The air exiting the filter is exhausted at a higher velocity than that entering it. Consequently, exhaust being vented inside a building can have an effect on the pattern of air circulation.

Air circulation patterns will vary depending upon which method is used and according to your specific shop setup. You can direct the flow of circulation on the air filter with the vents on the rear of the machine. These can optimize good layout and circulation, as shown in the Figure below.

Filter

Figure 6. Good air circulation. The air filter placement promotes circular air motion.

The directional vents will have little effect if the air filter is placed too close to obstructions, resulting in poor air circulation, as shown in the Figure below. In this situation, the velocity of the air is lost and circulation is diminished.

Filter

Figure 7. Poor air circulation. Placed too close to the wall, the air circulation short cycles, leaving much of the room unfiltered.

Below is a list of things to keep in mind when selecting a location to hang the air filter:

• Study your shop layout to determine the best location for the hanging air filter. The air filter must have at least 12" of clearance all the way around or the airflow will short-cycle.

• The air filter works most effectively when hung in front of sanders or areas where sanding is being done with hand-held equipment.

• Do not hang the air filter where garage doors will pass closely by or where it may impede transport or movement of any other object.

• Hang the air filter where it can be accessed easily for operation and cleaning.

Model G9956 (Mfg. Since 8/15) -13-

It is very important that the hanging air filter

be supported properly. Please follow these guidelines when planning where to mount the unit:

• Where the eye bolts attach is the top of the unit. The hanging air filter can only be secured by the eye bolts on its top.

• Make sure that an electrical outlet with a properly grounded receptacle is available at the location you choose.

• The air filter must be supported by joists or studs capable of supporting at least 150 lbs when mounting the unit with eye bolts.

DO NOT attach the hanging air filter to sheet rock, press board or paneling. These materials cannot support the filter, and it may fall.

• Avoid hitting your head on the hanging air filter. Make sure there is enough clearance between the unit and the ground, especially important in a basement. If possible, position the air filter in an area that has little foot traffic, but still offers easy access to the switch and filters.

Mounting

ONLY mount the air filter unit to joists, wall studs, or table that can hold at least 150 lbs.

DO NOT mount the unit only to sheet rock, pressboard, paneling, or honeycomb wall panels with expansion-type fasteners. The fasteners can tear out and the air filter can fall. Ignoring this caution can result in injury or property damage.

Filtering

Performance

The Model G9956 will recirculate the volume of air in a 20' x 20' x 8' room approximately 26 times in one hour.

We recommend that the volume of air in your room be recirculated at least 6-8 times every hour. Therefore, rooms with a larger volume will require two or more air filters to achieve proper filtering.

To calculate the recirculating rate for your shop space:

Step 1: Use the formula below to calculate how long it takes to circulate all the volume of air in a room with the double air filter; where W = Width, L

= Length and H = Height of your room, in feet. The maximum rate of air movement for the air filter is

1400 CFM.

Machine Storage

When the air filter is not in use, unplug the power cord from the power source. Place the cord away from potential damage sources, such as high traffic areas, sharp objects, heat sources, harsh chemicals, water, damp areas, etc.

Example: 20' x 20' x 8' = 3200 = 2.29 Minutes

1400 1400

Step 2: Calculate how many times per hour the volume is recirculated through the double air filter by dividing 60 minutes by the circulating time from

Step 1. The result is listed as times per hour.

Example:

2.29

SECTION 5: MAINTENANCE

Cleaning Filters

The frequency of use directly affects how often the filters must be cleaned or serviced.

To maintain optimal operation, check the filters approximately every 40 hours of use in light or moderately dusty environments. In very dusty environments, check the filters every eight hours of use. Always wear a respirator when checking, changing, or servicing the filters.

2. Lift the primary filter so it clears the retaining rim (see Figure 13), remove it, and examine it. Place the filter in a trash bag and shake it gently to remove the bulk of the dust.

Primary

Filter

Secondary

Filter

Unplug air filter before performing all maintenance procedures. Ignoring this warning may result in serious personal injury to you or others!

Always wear a respirator and safety glasses when cleaning the filters. Sawdust may cause allergic reactions or respiratory problems.

To change and service the filters:

1. DISCONNECT MACHINE FROM POWER!

DO NOT use compressed air to blow out the primary or secondary filters in the following steps. If you do, you will damage the filters and reduce filtering quality.

Figure 13. Filters exposed for cleaning.

3. Remove the secondary filter, place it inside a trash bag, and gently shake the dust from the inside of the filter.

Optional: Wash the secondary filter with water to remove the remaining dust, then let it dry completely.

4. Vacuum out the inside of the air filter housing.

5. Re-install both filters.

Note: The filters can be cleaned several times before replacement becomes necessary. To determine whether the filters need to be replaced, hold them up to the sunlight and visually inspect them after cleaning. If you can see a lot of light through them, the filters do not need to be replaced. If you cannot see a lot of light through them after cleaning, replace the filters.
