Page 5: Installation Guide
PHOENIX Electro-Pneumatic Operation INSTALLATION GUIDE POWER SUPPLY The power supply required for the filter is 24 VDC @ 1 Amp PNEUMATIC CONNECTIONS An 80 psi, clean and dry compressed air supply should be made to the ¼” connector on the Backwash Valve actuator. - Page 6 OPERATING REQUIREMENTS The Phoenix filter requires a minimum working pressure of 40 psi. This pressure will ensure that there is a minimum of 30 psi on the outlet of the filter at time of backwash, e.g. 10 psi differential pressure at backwash. Correspondingly, if a higher DP set point is desired, then a higher inlet pressure is required.

FILTER ELEMENT INSTALLATION Once the filter has been installed as per the Installation Guide and pressure tested, the filter elements can now be fitted. To gain access to the inside of the filter to install the filter elements, please follow the instructions below. Removing doughnut shaped cover: 1. - Page 9 CAUTION: WHEN FITTING ELEMENTS TO THE ELEMENT HOLDERS, THE ELEMENTS MUST BE HELD BY THE VERY TOP PORTION OF THE ELEMENT’S PLASTIC CAGE, ELSE DAMAGE MAY RESULT TO THE ELEMENT OR CAGE ASSEMBLY. ONCE FITTED THE SCREWS MUST BE CHECKED FOR TIGHTNESS ONE HOUR AFTER OPERATION.

Page 10: Operating Manual
OPERATING MANUAL Description The Phoenix filter is a fully automatic backwashing filter, comprising six patented filter elements in separate pods surrounding a central inlet chamber. The discharge from each pod is collected in a common area under the “doughnut” shaped filter cover before leaving via a common discharge port. -
Page 11: Components
1.0 Components 1.1 Filter Body Manufactured from stainless steel 304L, the filter body consists of six pods each containing a filter element and joined by a common inlet and outlet. Also connected to the central chamber of the filter is the backwash pipe. The inlet and outlet connections are 3” flange, ANSI 150 bolt hole pattern, and the backwash connection is 3/4”... -
Page 12: Discharge Regulating Valve
1.7 Discharge Regulating Valve It is essential to fit a regulating valve on the discharge of the filter for two reasons: 1. To ensure the correct flow rate through the filter, and 2. to provide the necessary head pressure on the filter’s discharge for efficient backwashing. -
Page 13: Differential Pressure Switch
Backwash Interval Timer (marked TIME) -This timer is used to set the maximum time between each backwash. There are six set-points ranging from 1 minute to 24 hours, please refer to Section 2.3. Terminal connectors labeled as follows: DPSW LOW: To connect from the DP’s ‘Normally Closed’... -
Page 14: Differential Pressure Switch
A differential pressure (DP) switch situated on the side of the filter monitors the filter’s common inlet and discharge pressures. The Phoenix will initiate an automatic backwash sequence once the DP switch reaches a predetermined set point adjusted by the operator. -

2.2.1 Backwash Set Point DP switch showing adjusting screws The DP set point may be adjusted by turning the adjusting nut located inside the switch cover. Turning this nut will alter the setting on the indicating gauge located on the outside of the switch. This indicator is for reference only. -
Page 16: Backwash Interval Timer
2.4 Backwash Interval Timer The Phoenix filter is designed to be operated with the DP switch provided. This ensures that backwashing follows the contaminant load on the filter, which will often be variable. - Page 17 High Torque: A thermal overload is fitted on the circuit board to protect the motor/gearbox from excessive torque. If the Indexing Valve Shoe is jammed and unable to continuing rotating, the thermal overload will shut off power to the circuit board. The pneumatically operated backwash valve will close.

Page 18: Filter Start-Up
3.0 Filter Start-Up Once the filter has been properly installed and after reviewing the filter’s control system, the filter may be started by following the procedure below. 1. With the inlet, discharge and backwash valves closed, start any pumps serving the filter. -
Page 19: Recommended Maintenance
4.0 Recommended Maintenance Depending on the application, the filter elements may require to be removed for cleaning at regular intervals. In any case, the following preventative maintenance program should be followed: Every Six Months 1. Visually inspect the following: a. No leaking around ‘Clampco’ ring clamp b. -

9. Examine the valve assembly for any heavy scoring on the valve shoe. Should the valve assembly be heavily damaged in any way, i.e. heavy scoring on shoe, then replace the shoe or the whole assembly. 4.4 Replacement of Indexing Valve Before replacing the valve assembly, examine the “O”... - Page 22 5. Remove the motor/gearbox assembly from the filter without moving the Indexing Valve shaft. Loosen the screw on the top of the opto disc and rotate the disc slightly and then tighten screw. 6. Connect power to circuit board, refer to Section 1.8, and initiate a backwash. 7.
