Installation; Initial Startup; Filter Disassembly / Assembly - STA-RITE PRDE40 El Manual Del Propietario

INSTALLATION

Installation of filter should only be done by qualified, li-
censed personnel.
Filter Assembly
Filter mount must:
Be solid, level, rigid, vibration free, and provide for ade-
quate drainage.
Be as close to pool as possible to reduce pressure loss
from pipe friction.
Provide weather and freezing protection.
Provide adequate ventilation to prevent motor from over-
heating.
Provide space and lighting for easy access for servicing
pump and piping (See Figure 1, Page 4, for space
requirements).
Piping:
NOTICE: Make sure that the filter and all piping can be
drained for winterizing. See "Winterizing", Page 9.
Piping must conform to local/state plumbing and sanitary
codes.
Use teflon tape, Plasto-Joint Stik
on all male connections of plastic pipe and fittings. DO
NOT use pipe compounds on plastic pipe; it will cause
the pipe to crack. Do not use sealant on unions – assem-
ble them dry and hand tight.
Support pipe independently to prevent strains on filter.
Fittings restrict flow; for best efficiency use fewest possi-
ble fittings.
For ease of maintenance, Sta-Rite union couplings are
provided to connect the piping to the filter inlet and out-
let ports.
Keep piping tight and free of leaks: pump suction line
leaks may cause trapped air in filter tank or loss of prime
at pump; pump discharge line leaks may show up as
dampness or jets of water.
NOTICE: Overtightening can crack filter ports.
Valves:
A check valve installed ahead of filter inlet will prevent
contaminants from draining back into pool.
A check valve installed between filter and heater will pre-
vent hot water from backing up into filter and deforming
internal components.

Electrical:
BE SURE pump grounding meets local and National
Electrical Code standards. All wiring, grounding of associ-
ated equipment must meet local and National Electrical
Code Standards.
INITIAL START-UP
Be sure pump is OFF
before starting procedure.
Do not operate these filters at more than 30 PSI
(207 kPa) under any circumstances!
To prevent serious damage to the element
fabric, NEVER run your DE filter without a diatoma-
ceous earth precoat!
1. Securely lock Posi-Ring
CLOCKWISE until it "clicks" past the safety latch (see
Figure 2). Stop turning as soon as the ring clicks past the
latch. The ring may feel slightly loose, but it will tighten
up when pump is on and filter is under pressure.
2. Install the pressure gauge and the air release valve (See
Figure 2) on the tank lid.

behind the safety latch.
3. Fill trap on pump with water.
4. Open air release valve on top of filter.
5. Open isolation valves.
6. Start pump to purge air from system.
