To reduce the risk of injury from accidental starting, turn the vacuum off and unplug the power cord before emptying the collection tank.

1. To remove top hood assembly from the collection tank, simply unlatch the two latches on either side of the collection tank and lift the top hood off the tank. Set the top hood assembly down on top of the filters.
2. Take hold of the top of the collection tank with one hand, lift the tank with the handle at the center bottom of the tank, and with your other hand, dump the contents into the proper waste disposal container.

WARNING

To reduce the risk of back injury or falls, do not lift a collection tank heavy with dust and debris. Scoop enough contents out to make the collection tank light enough for one person to lift comfortably.

Maintenance
The Pulse-Bac® requires little or no preventive maintenance; however the performance of the three cartridge filtration system can be enhanced by allowing the PB-1050 / PB-1150 / or PB-1250 to run for 3 to 5 minutes after each days use. The cartage filters should never be re-moved for cleaning. The only time the filters should be removed is when replacing old filters with new filters. Removing the filters for cleaning is highly discouraged as this action may cause many problems. If filters are not replaced properly damage can occur. For proper opera-tion when using a Pulse-Bac® vacuum for dust collection, filters should be changed a mini-mum twice a year.

Maintenance Continued
Although the Pulse-Bac® cleans it’s filters continuously during operation, small amounts of debris will cling to the surface of the filters under normal operating conditions. Operating the PB-1050, PB-1150, or PB-1250 for three to five minutes before and after each days use will help the filters to purge themselves of most dust and debris. This extra step will help to extend the life of the filters, enhance performance, and reduce operating cost.

Operating & Safety Tips

• Never operate in a wet environment.
• Never operate with an ungrounded power source.
• Never operate with an improper or ungrounded electrical extension cord.
• Never operate unattended.
• Never vacuum hot ashes or combustible materials.
• Never operate in conjunction with any ungrounded equipment.
• Always use a proper 120 volt 20 amp electrically protected outlet to operate.
• To reduce risk of electrical shock, do not expose to rain and always store indoors.
• Never operate the Pulse-Bac in the presence of explosive vapors.
• Always unplug the Pulse-Bac when not in use and before servicing.
• Turn your Pulse-Bac off before unplugging from the power source.
• Never operate the Pulse-Bac from a generator that is not earth grounded.

WARNING
Sparks generated by the vacuum motor can ignite flammable vapors or dust.

To reduce the risk of fire or explosion
Never vacuum or use the machine near flammable or combustible liquids, gases, or explosives fluids like gasoline, lighter fluids, cleaners, oil-based paints, natural gas, hydrogen, coal dust, magnesium dust, grain dust, gun powder or other types of flammable vapors or fuels.

Filter Installation
When you receive your new Pulse-Bac® you will be required to install the filters onto the vacuum head. Follow these instructions ( 1 ) thru ( 5 ) to insure proper filter installation.

1. If not already installed, install the O-Ring (P/N # 401979) onto the O- Ring groove at the top of the twist on filter as shown in figure 1.

2. If not already installed, install the foam Dust Ring (P/N # 403242) into the outer groove of the filter.
   NOTE: The foam dust ring helps to prevents dust from accumulating between the top of the filter and the filter receiver, it doesn’t create a seal for the filter. The O-Ring is the only seal for the filter.

3. Check to ensure that the filter receiver is clean and void of any dust or foreign material before screwing your filter into place.

4. Insert the filter into the filter receiver and twist in a clockwise direction until the filter just touches the base, then turn the filter one quarter turn to tightly secure it.

5. Once the filters have been installed, the vacuum is ready to be put into service.

Caution
Once you have installed the filters on the Pulse-Bac, the filters should never be removed unless they are to be replaced. Removing the filters after initial installation can cause various problems if not reinstalled properly. Since your new Pulse-Bac cleans its filters automatically, you should never have reason to remove the filters other than for replace-

If you need assistance or require additional information when installing the filters, you can contact CDCLarue customer services department at 918-216-6100. We will put you in contact with a technician that can help you accomplish the installation and answer any questions you may have.

Servicing Continued

• Connect your positive lead to points one, two and three individually on the solenoid connection block. Your VOM should read approximately 22 ohms at each test point if the solenoid is good and infinity or zero if the solenoid is bad. ( see pictorial # 2 ) on page 20.
• If you have a bad solenoid, you will need to remove the motor and it’s motor mount to gain access to the bad solenoids. You can determine which solenoid to replace by noting the color of the wire when taking readings from the solenoid connection block on the PCB. see page #13 for details on removing the motor and the motor mount.
• Turn to page #9 of this manual for the location and identification of test points on the printed circuit board.
• Connect your VOM negative test lead to the point on the solenoid connection block on the printed circuit marked ( SC ) or solenoid common.
• Once you determine which solenoid to replace, disconnect the solenoid from the valve stem by removing the retaining clip on the retaining pin then remove the retaining pin to release the solenoid plunger from the valve stem.
• Do not use the old solenoid plunger or remove the valve to replace the bad solenoid.
• Remove the solenoid control wires by removing the quick connect connectors and re-move the four Phillips screws holding the solenoid to the solenoid mounting plate by using a small #4 Phillips screw driver.
• Replace the bad solenoid by reversing the above directions used to remove the solenoid.
• When installing the new solenoid make sure you use lock tight on the Phillips screws holding the solenoid to the solenoid mounting plate. If you do not lock tight the screws holding the Solenoid to the solenoid mounting plate they may come loose and go through the motor fan causing irreversible damage.
• If you require help when replacing a solenoid, you can contact CDCLarue™ service department for support or conformation of details relating to the replacement of your solenoids.

Printed Circuit Board Replacement

• Disconnect the Pulse-Bac® from the electrical power source.
• Remove the hood cover by removing the four 5/16 “ X 10 X 3/4” screws holding it to the base plate. ( see pectoral # 1 ) on page # 20.

CDCLarue™ 5 / 3 Channel Timer PCB Revision “D”

Functional Description
Overview;
The Channel Timer circuit design supports several different operating modes – each of these modes are described in subsequent sections. At the heart of the design is a microcontroller which handles all of the processing. Upon initial power-up, the microcontroller reads the set-tings for the Duration & Cycle Adjust Timers and determines if board supports 3 or 5 channels. Once this information is determine, the Cycle Timer begins its countdown, once it expires, Solenoid #1 is activated and the Duration Timer begins its countdown. Upon expiration of the Duration Timer, Solenoid #1 is deactivated. Prior to activating the next Solenoid, the microcon-troller inserts a 5 second pause to allow the pressure in the tank to fully recover. Solenoid #2 is then activated for specified Duration, followed by another 5 second recovery period. This sequence repeats itself until the last Solenoid (either #3 or #5) has been activated, which com-pletes the cycle. The Cycle Timer is then reloaded and the countdown begins once again.

Fixed vs. Variable Duration
The ON duration of the Solenoids is either Fixed or Variable depending on the selected operating mode. The operating mode is determined by the R16. When R16 is installed, the unit operates in Variable Duration Mode, which has a range of 0.1 to 1 0 seconds (in 5 millisecond steps). When R16 is removed, the Duration is fixed.

Cycle Duration
The Cycle Duration has a range from 5 to 105 Seconds (in 200 millisecond steps). The actual time is determined by a potentiometer mounted on the board.

3ch vs. 5ch Selection
R14 determines whether the unit operates in 3ch or 5ch Mode. When R14 is installed, the unit operates in 5ch mode. When R14 is removed, the unit operates in 3ch mode.

110V vs. 220V Selection
Resistors R110A & B and R220 configure whether the unit operates with 110V or 220V input. For 110V operation, R110A & R110B should be installed (R220 must not be installed). For 220V operation, R220 should be installed (R110A & R110B must not be installed). These appropriate resistor configuration must be in the appropriate position prior to powering up the printed circuit board.

12Vdc Auxiliary Output
The Auxiliary 12Vdc output will provide approximately 200ma@12Vdc.

Sensor Support Circuit
The 12Vdc Auxiliary Output above may be used to power an external (sensor) circuit, which may in turn drive an on-board relay circuit. The terminal labeled “SOUT”, may be connect to the sensor’s output – this is actually an input (0 to 12Vdc), which is active high (input voltage from 3 to 12Vdc). The state of this input drives an output, RLY, which is a low side relay driver. This output can sink up to 200ma of current at 12Vdc.

Spare Input/Output
The board contains a spare I/O. At this time, there are no features associated with this provi-sion. If needed, this line can be used as a digital input, digital output, or for an analog sensor.

Positioning Optional Tank Capacity Sensor ( TCS )
Your new PB-1050, PB-1150, or PB-1250 may be equipped with CDCLarue™ exclusive TCS system, if not, you can order this option at anytime in the future as your machine is already equipped to accept the TCS feature at a later date. The TCS requires you to put it in it’s proper position prior to putting your Pulse- Bac® into service, this will insure proper operation of the PulseBac.

Position the TCS as follows

1. The TCS is shipped in the position shown in pictorial # 1.
2. Loosen the butterfly screw “A” and move the TCS rod to the upright position as shown in pictorial # 2.
3. Position the TCS rod at a 90° angle as shown in pictorial # 3.
4. Tighten the butterfly screw “A” to hold the TCS rod in place as shown in pictorial # 4. Do not over tighten the butterfly screw.
5. After the TCS rod is in place, the filters can be installed. (see page # 10 )

TANK CAPACITY SENSOR ( TCS )
The PB-1050, PB-1150, or PB-1250 can be equipped with CDCLarue™ exclusive Tank Capac-ity Sensor ( TCS ). The TCS system is designed to prevent the vacuum from over filling the collection chamber and causing damage to the filters and vacuum motor components. Be sure to read and understand the instructions for setting up the TCS system when you receive your Pulse-Bac® instructions for positioning the TCS rod. This can be found on page # 13 of this manual. If you require additional assistance when positioning the TCS call CDCLarue customer services at 1-918-216-6100.
Pictured below in ( figure #2 ) is the TCS in it’s proper position for operation inside the Pulse-Bac. The Pulse-Bac is equipped with operational indicators on the front control panel and operates as follows;

Warning
Once the TCS has turned the vacuum motor off and signaled the operator with a visual and audio alarm, the vacuum motor may restart automatically when the vacuum head is removed from the tank. Always turn the Pulse-Bac power switch to the off position before removing the head to empty the tank after the TCS system has engaged. IF not done, the vacuum motor will restart, causing the operator to possible injury his or herself. Turning the power switch to the off position will silence the audible alarm and extinguish the visual alarm while ensuring the vacuum motor will not restart.

1. When the TCS is installed on the Pulse-Bac, the front nameplate will be equipped with a red LED light indicator that when lit notifies the operator that the TCS has detected a full tank sounded an audible alarm and has turned the vacuum motor off. ( see fig. 1 )
2. The vacuum motor will not start unless the tank has been emptied or the sensor is cleared.
3. The audio alarm will continue to sound off until the sensor is cleared or power switch is turned off.

Changing Filters
WARNING: For your safety, always turn off and disconnect the vacuum from the power source before replacing filters or performing any type of service.

To Replace filters
Note: For best results, clean the bottom of the top filter receiver assembly after removing old filters and before replacing with new filters.

1. Remove the vacuum head from the collection tank and place it upside down on the floor or work bench.
2. Locate the filters, remove each filter by turning counter clockwise and pulling the filter straight up and away from the assembly.
3. Place a rubber o-ring and dust gasket on each new filter. Screw each filter on clockwise until snug, and then continue turning one quarter turn until filter is tightly fitted.
4. Place the vacuum head on top of the collection tank and secure it by latching it to the collection tank with the rubber latches. The Pulse-Bac® is now ready for service.

Note: Filters should be changed out regularly to maintain peak performance. Do not use a filter with holes or tears, or missing o-rings. The filters are made of high quality Spun Bond Polyester media with a P.T.F.E coating, designed to stop particles as small as .1 micron, the filters should be used for dry pick-up only, and changed out regularly. CDCLarue recommends the filters be changed every four to six months or twice annually.
