Electrical work must be performed by a qualified electrician and comply with all applicable national and local codes.

Turn power off and lock out electrical power sources before performing service or maintenance work.

Do not install in classified hazardous atmospheres without an enclosure rated for the application.

This light fixture uses a wrap-around lens that is not fastened to the light housing by fasteners or latches.

To remove the lens: Lift lens one side at a time up and away from the housing.

To replace the bulbs: Rotate and remove from the rotary-lock lamp holders.

Replace with 40-watt, 48-inch long fluorescent bulbs.

IEC Control Panel with Programmable Logic Control

This control panel contains a safety disconnect switch, blower motor control, pulse control functions, and a Magnehelic gauge. The Programmable Logic Control, PLC, provides features such as sequential start-up, staggered aftershift cleaning, and troubleshooting capabilities.

1. This control panel includes magnetic starters with a low-voltage control circuit.

2. The blower motor ON/OFF buttons are located on the control panel cover. A red blower motor RUNNING light is also provided.

3. Sequential start-up is provided for all DWS 4- and DWS 6-2, 3, and 4 modules. This allows a delay between starting each blower motor and reduces undesirable overload current at start-up.

4. The control panel has troubleshooting capabilities. If a blower motor shuts down due to a failure, such as an overload, the panel will flash the red RUNNING light quickly. The two amber lights, CLEANING and AFTERSHIFT CLEANING, will also flash indicating which circuit tripped the alarm.

For example: The overload on motor protector #3 is tripped. The red RUNNING light will flash quickly and the two amber lights, CLEANING and AFTERSHIFT CLEANING, will flash three times, then pause and repeat. This indicates that motor protector #3 has been tripped. The lights will continue to flash until the alarm is serviced.

5. Thermal overload relays and circuit breakers are provided for the motor circuit and fuses for the low voltage circuit. Standard voltages available are 208/230/460/575/60 Hz/3 phase.

Warning: This procedure requires trained personnel with PPE!

Sprinkler systems place a large quantity of water in the dust collector when activated. Provide adequate drainage to remove water. Excess water weight can cause the leg structure to collapse.

Optional fire control sprinklers are available for all models operating under negative pressure. Donaldson Torit supplied sprinklers require a minimum of 15 psig water pressure to each module. The volume of water discharged per sprinkler head is 20 gallons per minute.

Consult with local authorities when installing fire control systems on dust collection equipment.

1. Open the front access doors to access the sprinkler tap located in the dirty-air plenum.

2. Apply pipe sealant to the threads of the pipe reducer located on the sprinkler assembly.

3. Thread the sprinkler assembly onto the 1-inch diameter sprinkler tap.

Acoustic Curtain for Power Module

1. Install the acoustic curtain to the front of the power module by aligning the acoustic curtain holes with the non-louvre door holes and secure with nylon Christmas Tree clips.

Electrical work must be performed by a qualified electrician and comply with all applicable national and local codes.

Turn power off and lock out electrical power sources before performing service or maintenance work.

Do not install in classified hazardous atmospheres without an enclosure rated for the application.

Install chamber silencer after the motors are wired and rotation checked.

Install the silencer to the top of the power module using the hardware supplied.;
