The Delta P Plus Control offers three filter cleaning options.

1. Differential Pressure Cleaning (DFF) - When the pressure drop across the filters reaches the control's High setpoint, the control closes an output relay allowing a sequential timer to trigger the cleaning valves. When the control senses that the pressure drop has decreased to the Low setpoint, the relay opens and the cleaning cycle stops. This sequence continues as long as the collector is in use, maintaining the pressure drop within a narrow range.

2. Downtime Cleaning (DTC) - The Delta P Plus Controller monitors the collection system. When the pressure drop exceeds the Low Pressure Off set point and then approaches zero again, the Delta P Plus Controller runs a delay timer to allow the blower to come to a stop and then engages the cleaning mechanism for a preselected time.

3. Combined Differential and Down Time Cleaning (ALL) - The Delta P Plus Control combines the two functions described above; maintaining the pressure drop in a narrow band and down time cleaning the filters when the collector is shut down. The down time cleaning function can be toggled On or Off from the keyboard.;

Activate the pulse cleaning for 10 to 15 minutes to remove excess dust from the filter bags.

Remove header cover, if equipped.

Remove jet tubes and set aside.

Remove the hex nuts securing the wire insert. Remove the clamps and withdraw the insert and filter bag. Inspect insert for excess corrosion, broken mesh, or other damage and replace as necessary.

Slide the filter bag over the wire support frame as shown. Slide bag carefully until top of bag is tight against the support frame flange.

Place filter bag and wire support assembly in seal frame slots as shown.

Position clamps and tighten using a deep well socket and extension. Do not overtighten. Maximum recommended torque is 20 ft/lb.

Note: If filter bags are mounted horizontally, tighten bottom clamp first.
