7.1 Electrical connection (see figure 6)
The unit may only be connected by an authorized electrical
specialist.
Before the electrical connection is made, the unit must be filled;
if not, the bearings will be destroyed by dry operation.
Connect the pumps according to the proper connection scheme.
In case of unit equipped with timer follow the sequence shown in fig. 7.
7.2
Getting started
The pump may not be run dry, as this can destroy the bearings in
a very short time.
Before starting, the system must be:
- Filled.
- Rinsed thoroughly to prevent foreign objects and impurities from blocking the pump.
- Completely bled.
Audible flow noises indicate that there is still air in the pump.
Bleeding is sped up by repeatedly switching the pump on and off. If necessary, remove
the residual air as follows:
- Disconnect the pump from the mains.
- Slightly loosen the union nut and carefully open the supply line
until water runs out of the union nut. Prevent the electrical
connection to the pump from getting wet.
- Tighten the union nut again and reconnect the pump to the
mains.
7.3 Setting the timer (see figure 8B)
Set the current time by turning the setting dial (1) in the direction of the arrow until the
current time matches the marking (2). Pull out the tabs (3) for the times that the pump
should run. Set the function selection switch (4):
ON = pump runs continuously,
OFF = pump is off,
(TIMER) = pump runs according to the program that is selected by the tabs.
7.4
Setting the control thermostat
Select the desired temperature using the selector knob placed on the motor housing.
