CH. 3 INSTALLATION
DANGER
Electric shock
risk
WARNING
All SWIMMEY pumps are self-priming. If the pump is used to suck water, it is advisable to install it as close as
possible to the source. All pumps should be installed in a ventilated area to ensure sufficient air for cooling
purposes. Suction pipes should be air-sealed and show no signs of bends and/or counter slopes to avoid the
formation of air locks that could impair the regular operation of the pump. Pumps installed below the water level
should be insulated from the system. It is advisable to fit an on-off valve both on the delivery and suction side.
Pipes should be fitted in a position that protects the pump from vibrations, stresses and loads. Therefore, pipe routes
should be as short and direct as possible and avoid an excessive number of bends to limit load losses. The delivery
and suction pipes of Swimmey 33 should have a minimum diameter of 3". It is also necessary to make sure that
there is sufficient space around the pump for maintenance purposes.
CH. 4 ELECTRICAL CONNECTIONS

Electric connections should be made using cables H07RN-F (external connections) or H05RN-F or H07RN-F (internal
connections). For connections, refer to Figure 2 (single phase motors) or 3 (three-phase motors). Single-phase motors
have a continuously running condenser and an in-built thermal protection in the motor winding. The protections for
three-phase motors must be provided by customers. The electric system will have to have a cut-off switch with single-
pole switch.
CH. 5 STARTING THE UNIT
WARNING
WARNING
WARNING
Before starting the pump, fill the filtering body up to the suction level, after loosening the transparent plastic cover
of the filter. To fill pumps below the water level, slowly open the valve on the suction side when the delivery valve is
fully open to allow the pump drainage. Check that the pump rotates clockwise by looking at the pump from the motor
fan side. On three-phase pumps it is possible to invert the rotation by exchanging the two phases. These pumps are
self-priming. Priming time ranges from 1 to 5 minutes, with a suction height of 2÷3 m, in standard conditions (suction
pipe with an internal diameter of 50 mm, water temperature of 20°C, frequency 50Hz).
When installing, please ensure pump is disconnected from
electrical supply.
Protect the pump and all pipes from bad weather or freezing
conditions.
Verify that the voltage and frequency of the pump shown on the
nameplate correspond to those available on the mains.
The installer must make sure that the electric system is grounded in
accordance with the law in force.
Make sure that the electric system has a high-sensitivity circuit
D D D D D
breaker = 30 mA (DIN VDE 0100/739)
Use the pump for the applications listed on the nameplate.
Do not operate the pump without fluids.
Do not oparate the pump when the interception valve on the delivery
side is completely closed.
