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. There is no need to run exhaust lines from the actuator, as
snubbers have been fitted to the actuator for this purpose.
DIFFERENTIAL PRESSURE (DP) SWITCH
The filter is supplied with a DP switch connected hydraulically and electrically to the filter;
the operating range of this switch is from 2 to 45 psi (differential pressure). Should the
differential pressure across the filter exceed 45 psi, damage may occur to the switch.
The DP switch is wired using the common ( C ) and normally closed contacts (NC).
NOTE:
With an optional dual indicator Differential Pressure switch, the left set of terminals
are related to the lowest dial setting (backwash set point) and the right set of terminals are
for the highest setting (high set point).
PIPE CONNECTIONS
The filter inlet (bottom) and discharge (side) are 3 inch, 4 bolt flanges (ANSI 150 bolt hole
pattern). The backwash connection is a
¾
” NPT female which should be plumbed to a
suitable drain or tank capable of handling the system’s pressure.
To avoid excessive
pressure drops, which could impair backwash effectiveness, do not run the
backwash line more than 10 feet with the id of the line no less than
¾
”
.
FILTER SUPPORT
The filter can be either supported at the base of the six pods or at the inlet flange.
