Figure 11. Typical Water Piping Configuration
4.3 Water Connections
The heater should always be installed after the pump and
filter. All automatic sanitising devices must be installed after
the heater with a check valve between to keep water from
the sanitiser entering the heater directly.
A check valve is not required between the filter and the
heater.
1. For best pump performance keep suction pipe length
as short as possible with minimum number of bends
and use 50mm high pressure PVC suction and return
pipe. All equipment such as filters, heaters, chlorinators
must have a minimum of 50mm connections.
2. Secure unions to the attaching pipe work, using
approved priming fluid and solvent cement as normal
practice, coating both surfaces.
NOTE: Always wear protective gloves when handling and using glue
and priming fluid. Ensure no excess adhesive runs into the
union, which may compromise sealing or removal abilities.
Allow 24 hours to dry before starting pump. Do not use “green”
glue on unions. This can cause damage to the ABS material
used to manufacture the unions.
3. Install check valves before the pump section and after
equipment if the pump is below the water level of the
pool.
4. For pump installations 500mm above water level, it
generally requires a foot valve at the pool or check
valve in the suction line. Suction lines must be installed
below water level until just in front of pump location
and vertical riser used to reach pump inlet. AstralPool
pumps are rated to a maximum head of 25 meters
however refer to your pumps data plate for actual
achievable pressure
5. All pumps will operate quieter and perform more
efficiently if a straight pipe length of 450mm minimum is
plumbed into the front of the pump.
6. Water temperature not to exceed 45 degrees
