Pressure Testing
WARNING
When pressure testing a system with water, air is often
trapped in the system during the filling process. This
air will compress when the system is pressurized.
Should the system fail, this trapped air can propel
debris at high speed and cause injury. Every effort to
remove trapped air must be taken, including opening
the bleed valve on the filter and loosening the pump
basket lid while filling the pump.
WARNING
When pressure testing the system with water, it is
very important to make sure that the pump basket lid
is completely secure.
1.
Fill system with water using care to eliminate
trapped air.
2.
Pressurize the system with water to no more than
35 PSI.
3.
Close valve to trap pressurized water in
system.
4.
Observed system for leaks and/or pressure
decay.
Section 4. Operation
4.1
Start-up
CAUTION
Never run the pump without water. Running the pump
"dry" for any length of time can cause severe damage
to both the pump and motor and void the warranty.
If this is a new pool installation, make sure all piping
is clear of construction debris and has been properly
pressure tested. The filter should be checked for
proper installation, verifying all connections and
clamps are secure according to the manufacturer's
recommendations.
WARNING
To avoid risk of damage or injury, verify that all power
is turned off before starting this procedure.
1.
Release all pressure from the system and open
the filter pressure release valve.
2.
If the pump is located below the water level of
the pool, opening the filter pressure release valve
will prime the pump with water.
3.
If the pump is located above the water level of
the pool, remove the lid and fill the basket with
water before starting the pump.
4.
Prior to replacing the lid, check for debris around
the lid o-ring seat. Debris around the lid o-ring
seat will cause air to leak into the system, and
make it difficult to prime the pump.
5.
Hand-tighten the lid to make an air tight seal.
Do not use any tools to tighten the lid, hand-
tighten only. Make sure all valves are open and
the unions are tight.
6.
Restore power to the pump, the turn on the
pump.
7.
Once all the air has left the filter, close the
pressure release valve.
8.
The pump should prime. The time it takes to
prime will depend on the elevation and length
of pipe used on the suction supply pipe. See
Section 3.1.3.3, Installation Recommendations
for proper elevation and pipe size.
9.
If the pump does not prime and all the instructions
to this point have been followed, check for a
suction leak and then repeat Steps 2 through 7.
