INSTALLATION

Installation of filter should only be done by qualified, licensed personnel. For assem-
bly and filling instructions, see pages 6 and 7.
Filter mount must:
• Provide weather and freezing protection.
• Provide space and lighting for easy access for routine maintenance. (See Figure I
and Table 1, Page 4, for space requirements.)
• Be on a reasonably level surface and provide adequate drainage.
• Be as close to pool as possible to reduce line loss from pipe friction.
Piping:
• Piping must conform to local/state plumbing and sanitary codes.
• Use pipe joint sealing compound or Teflon tape on all male connections of metal
pipe and fittings (except unions). Use Teflon tape or Plasto-Joint Stik
connections of plastic pipe and fittings. DO NOT use pipe dope on plastic pipe; it
will cause stress cracking of the pipe. Do not use sealant or tape on unions – as-
semble them dry and hand tight.
• Do not damage union sealing surfaces and O-Rings.
• Support pipe independently to prevent strains on filter or valve.
• Use 2" pipe to reduce pressure losses as much as possible.
NOTICE: Filter may be located away from pool, but for adequate flow larger pipe
may be needed. For more information about hydraulic design, call
Sta-Rite Customer Service.
• Fittings restrict flow; for best efficiency use fewest possible fittings.
• 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 prevent hot water from back-
ing up into filter and deforming internal components.
• Install Sta-Rite Two Position Slide Valve or Multiport Selector Valve with filter. See
Table lll.
• Filter ports and valve ports are furnished with union connections.
DO NOT use pipe sealants on union collar (nut).
• Use care before assembly not to damage union sealing surfaces or O-Ring.
Wastewater:
• Be sure all provisions for waste water disposal meet applicable local, state or na-
tional codes. 100 gallons (379 liters) or more of pool water will be discharged dur-
ing filter backwashing. Do not discharge where water will cause flooding or
damage.
Assembly:
See Pages 6 and 7 for assembly filling instructions.
