INSTALLATION OF BX, CTX & E SERIES PUMPS
A. Plan position of pump so that it will be:
1.
Free of water flooding, such as in a sump, garden hollow, ditch or at the bottom of a bank.
2.
On a stable base so that:
a) The pump is not left suspended by its fittings, causing a leak or failure with loss of water.
b)
Movement through vibration is restricted
c)
No strain is put on attaching pipe or other expensive equipment
3.
Accessible for maintenance and easily removed for service.
4.
Breathing space. Pump should not be crowded which will prevent cooling airflow from fan.
Overheating due to lack of cooling voids warranty.
Within reach of power point without extension cables as plugs liable to corrosion, shorting, etc.
5.
6.
At a minimum height of suction lift of water from pool surface to pump inlet.
B. For best pump performance keep suction pipe length as short as possible with minimum number of bends
and use 50mm PVC suction pipe for 750W (1hp) to 1700 W (2.0 hp).
50mm suctions should be used.
C. Minimum pipe diameters should be used on the following pumps
40mm - E 140, E190, E230, CTX180
50mm - E 290, CTX280, CTX360, CTX400, CTX610, BX1.0, BX1.5, BX2.0, BX3.0
D. Secure the barrel unions supplied into 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 proper affecting the
sealing or removal abilities. Allow 24 hours to dry before starting pump.
E. Install isolation valves before the pump section and after equipment if the pump is below the water level of
the pool.
F. 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
metres however refer to your pumps data plate for actual achievable pressure
G. All pumps will operate quieter and perform more efficiently if a straight length of 450mm pipe is plumbed
horizontally into the front of the pump.
H. Water temperature not to exceed 45 degrees
I.
Pumps must be either
- supplied by an isolating transformer, or
- supplied through a residual current device (RCD) with a rated residual operating current not
exceeding 30mA.
