WARNING

THIS VALVE OPERATES UNDER HIGH PRESSURE. WHEN ANY
PART OF THE CIRCULATING SYSTEM (e.g.. CLAMP, PUMP,
FILTER, ETC.) IS SERVICED AIR CAN ENTER THE SYSTEM AND
BECOME PRESSURIZED. PRESSURIZED AIR CAN CAUSE THE
LID TO BE BLOWN OFF WHICH CAN RESULT IN SEVERE
INJURY, DEATH, OR PROPERTY DAMAGE. TO AVOID THIS
POTENTIAL HAZARD, FOLLOW THESE INSTRUCTIONS.

CAUTION

If the valve is hard to rotate, shut the pump off before rotating between positions. Do
not use excessive force. If shutting off the pump did not ease the rotation, service
the valve as described in this manual. There may be foreign objects obstructing
one of the internal components.

CAUTION

It is recommended that the pump be shut off before cycling the valve. If your system
has a valve on the waste line make sure it's open. Sudden shifts in water flow can
damage system components.

This valve is available in two models for use with sand type or diatomaceous earth
type pool filters. Be certain that you have the correct model for your filter.
Installation the incorrect model may cause your pump to dead head, or drain the
pool when in backwash position.

WARNING

The filtration system may drain to the pool when the top of the filter is higher than 7 ft. from the pool water level. This may
require your system to prime after long periods of inoperation. Install a check valve on the waste port, if the top of the filter is
higher than 7 ft. from the pool water level.

Be careful not to allow any glue to get into the central bore of the valve body, as this can damage the internal components.
Do not use excess amounts of glue. Position the handle half way between the backwash and filter.

WARNING

DO NOT OPERATE THIS UNIT ABOVE THE MAXIMUM OPERATING
PRESSURE OF THE VALVE OR THE FILTER. OPERATING YOUR
SYSTEM ABOVE MAXIMUM RECOMMENDED PRESSURES MAY CAUSE
YOUR FILTER OR VALVE TO BLOW OFF AND RESULT IN SEVERE
BODILY INJURY, DEATH, AND PROPERTY DAMAGE. NEVER CONNECT
THE FILTER AND VALVE UNIT TO A PUMP, WHICH CAN GENERATE A
PRESSURE THAT EXCEEDS THE OPERATING PRESSURE OF THE
FILTER OR VALVE.

NOTE

Frequency of required lubrication depends on many factors including frequency of actuation, water chemistry, water
quality, and water temperature. Pentair Pool Products recommends inspection of the Waste Seal and the small shaft
seal after three months to ensure that they are still well lubricated. The valve may be reassembled and checked again
in three more months. O-rings that have been cut, nibbled out, or twisted may be signs of inadequate lubrication.
Damaged O-rings must be replaced.

CAUTION

If the valve handle becomes hard to twist during operation, it is an indication the seals no longer have adequate lubrication
and should be re-lubricated. Continuing to actuate a valve without proper lubrication will damage the O-ring seals and
cause the valve to leak.

CONTINUING TO OPERATE A VALVE WITH DAMAGED COMPONENTS COULD RESULT IN SUDDEN FAILURE OF
VALVE STRUCTURAL COMPONENTS, WHICH COULD POSSIBLY CAUSE FLOODING OR SERIOUS PERSONAL
INJURY DUE TO A SUDDEN RELEASE OF FILTER SYSTEM PRESSURE. INSPECT AND SERVICE YOUR VALVE
REGULARLY AS OUTLINED IN SECTION III.

NOTE

If the Rotary Assembly will be left in the valve body during the winter, lubricate the valve first to ensure that the piston
assembly will actuate easily after several months without movement.
