NOTICE: Use of valves other than those listed above could cause reversed water flow through filters and damage to internal fil- ter components.

INSTALLATION

Installation of filter should only be done by qualified, licensed personnel.

Filter mount must:

Provide weather and freezing protection.

Provide space and lighting for easy access for routine maintenance. (See Figure 1 and Table II, Page 6, 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 Teflon tape or 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—assemble them dry and hand tight.

Support pipe independently to prevent strains on filter or valve.

Use 2” (51mm) 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 for 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.

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 backing up into filter and deforming internal components.

Install Sta-Rite Two Position Slide Valve or Multiport Selector Valve with fil- ter. See Table I.

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.

To allow recirculation during precoat (if precoat pot is used), install a recir- culation line with shut-off between pad return line and pump suction.

Electrical

All wiring, grounding and bonding of associated equipment must meet local and/or National Electrical Code standards.
