Electrical connections

WARNING Electrical connections should be made by a qualified electrician in compliance with all relevant codes. Failure to comply may cause serious injury.
The PM1250 Electrostatic AFS is prewired for a single-phase, 120V power. It is provided with a plug designed for use on a circuit with a grounded outlet that looks like the one pictured in Figure 5-1.
It is recommended that the PM1250 be connected to a dedicated 15 amp circuit with a circuit breaker or fuse. If fuses are used, they should be a time-delay fuse marked “D”. Local codes take precedence over recommendations.
IMPORTANT: This electrostatic unit must be electrically grounded for proper operation, as well as for safety reasons (see below).

GROUNDING INSTRUCTIONS

1. All Grounded, Cord-connected Tools: This machine must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided – if it will not fit the outlet, have the proper outlet installed by a qualified electrician. Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

WARNING Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Failure to comply may cause serious or fatal injury.

Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool’s plug. Repair or replace damaged or worn cord immediately.
2. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating of less than 150 volts: This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Figure 5-1.

Extension cords

The use of extension cords is discouraged. Try to position machines within reach of the power source. If an extension cord must be used, make sure it is heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating. Table 2 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Unpacking

Shipping contents

Open shipping cartons and check that all parts are intact. Report any damage or missing parts to your distributor. Note that your unit may be provided with extra fasteners. Read the instructions manual thoroughly for assembly, alignment, and maintenance instructions.
1 Air filtration unit
2 Side plates
1 Baseplate
1 Remote control (batteries not included)
2 Knobs
6 Pan head screws with washers M5x10
4 Rubber pads
1 Cleaning brush
1 Operating instructions and parts manual
1 Product registration card

Assembly

Assemble the base of the unit with provided screws and washers, as shown in Figure 8-1.
If the filtration unit is to remain portable, press the four rubber pads into the mounting holes.
The unit may also be fixed to a table, wall or ceiling, using appropriate fasteners (not included) through four holes in base. See Figure 4-1 for hole pattern. 3/8” diameter fasteners are recommended. NOTE: First secure assembled base to structure, then mount filtration unit with the two knobs.

WARNING
Wall or ceiling structure must be capable of supporting the weight of air filtration unit and absorbing any vibrations arising from the unit. Appropriate fasteners must be used to secure to structure. Failure to comply may cause serious injury.

Operation

Tilt Adjustment

Loosen side knobs and tilt frame to any position. Retighten both knobs. For best results, when the unit is ceiling-mounted position front (filter side) downward; when the unit is table-mounted position front (filter side) vertically.

Basic procedure

Refer to Figure 8-2.

1. Plug in the unit. On/off indicator light glows red for standby mode.
2. Press the Power button to start the unit. The speed indicator light glows green, and the default speed is selected.
3. Press and release the Speed button until desired speed indicator is green.
4. Press the Timer button until desired timer indicator is green. If the Timer button is not pressed again for 3 seconds, the selected time indicator will flash multiple times, then stay green.
5. The unit will count down from the corresponding time, and will automatically shut off at time expiration.

Example: 8H indicator stays green when timing begins; switches to 4H indicator after four hours, then to 2H indicator after another two hours, then to 1H, and finally unit will shut off and remain in standby condition.
Note: If the Timer function is not used, unit will continue to operate until Power button is pressed.
All the above functions can be operated remotely. See Figure 8-3. The remote control uses radio frequency, and thus is not limited to line-of-sight operation.

User-maintenance

The batteries should be changed in the remote control as needed, particularly if unit seems unresponsive to remote operation.

Filter cleaning and replacement

The disposable filter is designed for approximately 3000 hours of life, dependent upon speed setting and working environment. See Table 3.

Filter life may be extended by the occasional use of a shop vacuum or compressed air to clean off the dust. However, a dirty filter should be replaced as it will diminish the efficiency of the unit.
Clean the filter after every 1000 hours of operation, or more frequently if needed. The unit is programmed to alert the user after 1000 hours; the red indicator light will flash twice per second.
After 3000 hours of operation, the filter should be discarded and replaced by a new one.

To remove filter:

1. When filter life reaches programmed time (1000 hours), red Reset indicator light will flash twice per second.

2. Turn off the unit.
   CAUTION: The internal metal ring carries an electrical charge during operation. Turn off unit before attempting to remove the cover.

3.  Rotate cover counterclockwise and remove it, along with the prefilter. See Figure 8-4.

4. Hold the frame stationary, and rotate the filter counterclockwise to remove it.

5. Clean dust from the filter with a vacuum or soft bristle brush. Blow dust from recessed areas of the filter with a household air blower. Also, clean out any residual dust from inside the unit.
   To install cleaned or replacement filter:

6. Center filter onto stator and turn it clockwise (about 1/8 of a turn) until it fully engages – you will feel a hard stop.

7. Install cover and rotate clockwise until it fully engages. A lock/unlock graphic is molded into the left and right edges of the cover as a guide.
   Note: A sensor prevents the unit from starting if the cover is not installed properly.

8.  Plug-in unit. Red Reset indicator light will flash.

9. Press and hold the Power button for 5 seconds until red indicator light goes off. The filter life count is now reset.

Anion generator maintenance

Remove dust regularly from the anion generator (i.e. carbon brush) with the provided cleaning brush. See Figure 9-1.

Additional servicing

Any additional servicing should be performed by authorized service personnel.
