GENERAL INFORMATION
• Clean a new pool as well as possible before filling pool and operating filter.
Excess dirt and large particles of foreign matter in the system can cause serious
damage to the filter and pump.
NEVER test this filter with compressed air.
Do not operate filter at water temperatures above 95°F (35°C).
NEVER operate this filter system at more than 50 pounds per square inch
(50 PSI/345 kPa) pressure!
INSTALLATION
Installation of filter should only be done by qualified, licensed personnel.
For assembly and filling instructions, see page 6.
Filter mount must:
• Provide weather and freezing protection.
• Provide space and lighting for easy access for routine maintenance. (See
Figures 1 and 2, Table II, 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

on
all male connections of plastic pipe and fittings. DO NOT use pipe dope on
plastic pipe; it will cause the pipe to crack. Do not use sealant or tape on
unions – assemble 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 1-1/2 or 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. Check local codes when considering remote installation.
• 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.
• When unions are provided, use as follows for leak free connections:
1. O-Ring and sealing surfaces must be clean.
2. Assemble hand tight only (no wrenches).
3. No pipe compound or teflon tape on unions.
Valves:
• A check valve installed between filter and heater will prevent hot water from
backing up into filter and deforming internal components.
• 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
national codes. 100 gallons (379 liters) or more of pool water will be dis-
charged during filter backwashing. Do not discharge where water will cause
flooding or damage.
