5.2 Electrical connection
The electrical connection must be made by a
qualified electrician and comply with
applicable local standards.
- Electrical connections must run via a fixed
connection pipe equipped with a connector device
or all-pole switch with at least 3 mm contact gap
width.
- To ensure that PG connector is protected against
water penetration and that strain-relief is provided, a
connection pipe with adequate external diameter
must be used (e.g. H 05 VV-F 3 G1,5).
- Check the current type and voltage of the mains
connection.
- Observe the type plate information for the pump.
- Connect the pump to the mains according to the
circuit diagram ( FIG. 4 ). Loosen the screws
( FIG. 2 - item 5 ) and remove the terminal box cover
( FIG. 2 - item 6 ). The pin designations are located on
the terminal rail.
- Observe earthing.
- Once the electrical connection is complete close
and screw in the terminal box cover.
6. STARTING UP
6.1 Filling, degassing
- Fill the device correctly. The pump rotor housing is
ventilated automatically, even after short periods of
operation. Short periods of dry running do not
damage the pump.
7. SERVICING
Maintenance and repair work should be carried out
only by qualified specialist personnel !
WARNING ! Risk of electric shock !
Exposure to electrical energy must be
prevented.
When carrying out maintenance and repair work the
pump must be switched off and protected against
unauthorised restarting.
- Damage to the connection cable must only be
repaired by a qualified electrician.
WARNING ! Risk of scalding !
Depending on the temperature of the flow
medium and system pressure hot flow medium may
form in a liquid or vapour state when disassembling
the pump and may be ejected under high pressure.
- Before disassembling the pump close the shut-off
devices on both sides of the pump. Allow the pump
to cool first.
5. INSTALLATION
The pump must be installed in a frost-free/dust-free
and well-ventilated environment and protected from
harsh weather conditions.
5.1 Assembly (FIG. 1)
Risk of damage to the pump!
Dirt can cause pump failure.
The pump should only be assembled following
completion of all welding and soldering work and, if
necessary flushing of the pipe system.
For connection with the water supply
network, the use of new accessories is
necessary.
- Assemble the pump in an accessible area with
suction-side and delivery-side gate valves to enable
subsequent inspection or replacement.
- Depending on the application it may be necessary
to replace the delivery-side gate valve with a spring-
loaded non-return valve.
- The gate valves are not required on models SB 04-
15V, since their function is assumed by the integrated
non-return and ball valves.
Risk of damage to the pump !
In the case of the versions with check
valve and non-return valve, these are already pre-
assembled with a tightening torque of 15 Nm (hand-
tight). If the tightening torque is too high, this will
destroy the valve screw connection and the O-ring.
When installing the valve, use a wrench to prevent it
from turning!
- Carry out voltage-free assembly using horizontal pump
shafts.
- Observe the installation positions given ( FIG. 3 ).
Risk of damage to the pump !
The screwed cable gland
(FIG. 2 - item 3) must face downwards, otherwise water
can penetrate the motor housing. If necessary, twist
the motor housing after releasing the union nut
(FIG. 2 - item 4).
Take care not to damage the housing gasket.
- The directional arrow on the pump housing shows the
direction of flow.
- On the Thermo SB 04-15V, the non-return valve
( FIG. 2 - item 1 ) is screwed down on the outlet
branch, whilst the ball shut-off valve ( FIG. 2 - item 2 ) is
screwed down on the suction branch.
- The ball valve is open when the slit is in the direction
of flow.
- The ball valve is closed when the slit is against the
direction of flow.
