Winterizing
• Protect the pump from freezing.
• Remove all plugs and drain the pump and all piping.
• Store drains and plugs in the strainer basket.
• Remove the pump to a dry and warm room.
• Do not wrap the motor with plastic covering as con-
densation may damage the pump.
• In installations where the pump can not be drained, a
40% propylene glycol, 60% water solution will protect
to -46°C.
• Do not use other anti-freeze solutions, these are all
highly toxic and will damage the pump.
Section 5
Electrical connection
The electrical motor must be wired by a professional ac-
cording to this installation instruction and all applicable lo-
cal regulations.
By introduction of the pumps a motor security has to be
foreseen by the installation. The security has to be tuned
in to the nominal power of the motor.
Single phase
0.55kW/230V - 3.6A
0.75kW/230V - 4.8A
1.1kW/230V - 6.7A
1.5kW/230V - 9.0A
2.2kW/230V - 12.2A
The supply voltage should be within ± 5% of the design
voltage, specified on the nameplate of the motor.
Single-phase motors should be connected at the two
terminals as indicated in the junction box.

Make sure that you interrupt the power supply
to the cables when connection the cables of the
pump
Please check the turning direction of three-phase motors
following each connection. If this does not correspond to
the arrow on the motor two phase connections in the junc-
tion must be reversed.
Every motor must be permanently grounded.
Connections which do not conform to the above men-
tioned safety instruction are not covered by the war-
ranty.

Servicing
The pump is designed to operate for many years without
servicing. If a failure does occur, it most likely will be a
moving part of the pump.
Always disconnect the power supply to the
pump before servicing.
The replacement of the electrical motor must be done by
a professional.

5. Strainer basket or skimmer basket is clogged
6. Closed valve in piping system
7. Air leak in suction line
Motor does not turn
1. Power switch is off
2. Circuit breaker has tripped
3. Pump is off-mode of a timer controlled circuit
4. Motor terminal connections are incorrect
5. Motor shaft is locked by bad bearing
6. Impeller is locked by debris
Low flow / high filter pressure
1. Filter is dirty
2. Restriction in return line
Low flow / low filter pressure
1. Strainer basket or skimmer basket is clogged
2. Clogged impeller
3. Air leak in suction line
4. Restriction in suction line
5. Reverse rotation of motor (three phase only)
Noisy pump
1. Air leak in suction
2. Foreign matter in pump housing
3. Cavitation
