USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
WARNING
– Hazardous Pressure.
Pool and spa water circulation systems operate under
hazardous pressure during start up, normal operation, and after pump shut off. Stand clear of circulation
system equipment during pump start up. Failure to follow safety and operation instructions could result in
violent separation of the pump housing and cover, and/or filter housing and clamp due to pressure in the
system, which could cause property damage, severe personal injury, or death. Before servicing pool and
spa water circulation system, all system and pump controls must be in off position and filter manual air
relief valve must be in open position. Before starting system pump, all system valves must be set in a
position to allow system water to return back to the pool. Do not change filter control valve position while system pump is
running. Before starting system pump, fully open filter manual air relief valve. Do not close filter manual air relief valve until a
steady stream of water (not air or air and water) is discharged.
WARNING
–
Separation Hazard.
Failure to follow safety and operation instructions could result in
violent separation of pump and/or filter components. Strainer cover must be properly secured to pump housing with
strainer cover lock ring. Before servicing pool and spa circulation system, manual air relief valve must be in open
position. Do not operate pool and spa circulation system if a system component is not assembled properly, damaged, or
missing. Do not operate pool and spa circulation system unless filter air relief valve body is in locked position in filter
upper body
WARNING –
Electrical
Ground motor before connecting to electrical power supply. Failure to ground
pump motor can cause serious or fatal electrical shock hazard.
WARNING –
Do NOT ground to a gas supply line.
WARNING –
To avoid dangerous or fatal electrical shock, turn
OFF
power to motor before working on
electrical connections.
Your Hayward Pro Series high-rate sand filter is a high
performance, totally corrosion-proof filter that blends
superior flow characteristics and features with ease of
operation. It represents the very latest in high-rate sand
filter technology. It is virtually foolproof in design
and
operation and when installed, operated and maintained
according to instructions, your filter will produce clear,
sparkling water with only minimal attention and care.
HOW IT WORKS
Your filter uses special filter sand to remove dirt particles
from pool water. Filter sand is loaded into the filter tank
and functions as the permanent dirt removing media.
The pool water, which contains suspended dirt particles,
is pumped through your piping system and is
automatically directed by the patented filter control valve
to the top of the filter tank. As the pool water is pumped
through the filter sand, dirt particles are trapped by the
sand bed, and filtered out. The cleaned pool water is
returned from the bottom of the filter tank, through the
control valve and back to the pool through the piping
system. This entire sequence is continuous and
automatic and provides for total recirculation of pool
water through your filter and piping system.
After a period of time, the accumulated dirt in the filter
causes a resistance to flow, and the flow diminishes.
This means it is time to clean (backwash) your filter.
With the control valve in the backwash position, the
water flow is automatically reversed through the filter so
that it is directed to the bottom of the tank, up through
the sand, flushing the previously trapped dirt and debris
out the waste line. Once the filter is backwashed
(cleaned) of dirt, the control valve is manually
resequenced to Rinse, and then Filter, to resume normal
filtering.
