4.3 Water Connections
The heater should always be installed after the pump
and filter. The water connections are located on the
right hand side of the heater. The inlet and outlet
are clearly marked. Water connections must be
completed in 50 mm PVC glue in plumbing.
All automatic sanitising devices must be installed after
the heater and in such a way that the sanitiser cannot
enter the heater without first mixing with the water in
the pool or spa. Sanitisers that are connected prior to
the heater will void heater warranty.
A non-return valve is not required to be fitted
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 lters,
heaters, chlorinators must have a minimum of 50mm
connections.
2. Secure the barrel unions supplied into the attaching
pipe work, using approved priming uid and solvent
cement as normal practice, coating both surfaces.
NOTE: Always wear protective gloves when handling
and using glue and priming uid. Ensure no excess
adhesive runs into the union proper aecting the
sealing or removal abilities. Allow 24 hours to dry
before starting pump. Do not use “green” glue on
barrel unions. This can cause damage to the ABS
material used to manufacture the unions.
3. Install isolation 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
eciently if a straight length of 450mm pipe is
plumbed horizontally into the front of the pump.
6. Water temperature not to exceed 45 degrees
7. 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.
4.4 Electrical Connections
The XT Pump is supplied with a standard 10 amp 3-pin
plug for connection to a 240V 10 amp GPO. All pool or
spa equipment connected to mains power should be
protected by an RCD circuit breaker.
The provided controller is a complete plug-n-play
assembly requiring no additional wired connection.
4.4.1 Voltage Checks
The correct voltage, as specified on the pump data plate,
is necessary for proper performance and long motor
life. Incorrect voltage will decrease the pump’s ability to
perform and could cause overheating, reduce the motor
life, and result in higher electric bills.
It is the responsibility of the electrical installer to provide
data plate operating voltage to the pump by ensuring
proper circuit sizes and wire sizes for this specific
application.
Most applicable wiring/installation codes require pool
pump circuits to be protected with a Ground Fault
Circuit Interrupter (GFCI), also commonly referred to
as a Residual Current Device (RCD). Therefore, it is also
the responsibility of the electrical installer to ensure
that the pump circuit is in compliance with this and all
other applicable requirements of the installation and
wiring code(s)/standard(s) applicable and enforced in
the area of installation.
CAUTION
Failure to provide data plate voltage (+/- 10%) during
operation will cause the motor to overheat and void
the warranty.
4.4.2 Electrical Wiring
WARNING
Viron pumps include Printed Circuit Boards (PCBs)
and microchips. It is necessary to turn power off
completely for 10 seconds before turning pump back
on again. Some brands on chlorinators may bleed
a small amount of power into the Viron Pump even
when the pump off mode is selected. If this occurs,
the Viron Pump may not reset correctly and may
not start until power is disconnected completely. In
some cases, the manufacturer of these chlorinators
may be able to remove or change a capacitor which
will completely disconnect power to the pump when
turned off. If not, a suitable chlorinator may be
required to be purchased. Astral Pool chlorinators
completely disconnect power to the pump when the
pump off mode is selected.
