5. Installation

5.1 Location

The booster set should be placed in a well-ventilated room to 
ensure adequate cooling of the pump motors. It should be placed 
with a 0.5 metre clearance in front and on the two sides.

The tanks can be placed on the discharge manifold or on the 
floor/wall anywhere around the booster set.

5.2 Foundation

The booster set does not require a special foundation, but it 
should be positioned on a plane and solid surface, e.g. a concrete 
floor.

5.3 Pipework

The pipes connected to the booster set must be of adequate size 
(2"). To avoid resonance, expansion joints should be fitted in the 
suction and discharge pipes/manifolds. See fig. 3. Either end of 
the manifolds can be used for pipe connections. 

In the case of suction lift installation, the suction manifold must be 
removed and each pump must be fitted with its own suction pipe 
and non-return valve.

Additional tanks have to be placed on the floor/wall anywhere 
around the booster set. The pipes must be fastened to parts of 
the building to ensure that they cannot move or be twisted. 
See fig. 3.

The booster set should be tightened up before start-up.

2. Pipe hanger.

The tanks, expansion joints and pipe hangers shown in fig. 3 ar
not included in the standard booster set.

5.4 Dry-running protection

Accessory:

 It is possible to install a pressure switch (normally 

open (NO)) on the suction side of the booster set to monitor the 
inlet pressure and to prevent the booster set from running dry 
(a level switch can be used if the suction side is connected to an 
open tank).

When the inlet pressure/level drops below the set value (0.4 bar), 
the pumps are cut out and the alarm is activated. When the 
correct pressure/level is restored (1.2 bar), the pumps are cut in 
automatically. In the case of three-phase versions, the alarm 
must be reset manually.

5.5 Overpressure protection

Accessory for three-phase versions only: 

An additional 

pressure switch can be installed on the discharge side of the 
booster set to protect the discharge pipes and components 
against overpressure. This pressure switch can be set to the 
maximum operating pressure or lower according to system 
condition.

When the maximum pressure is reached, the pumps will be cut 
out and the alarm is activated. When the correct pressure is 
restored, the pumps are cut in automatically. The alarm must be 
reset manually.

5.6 Tank selection

To ensure reliable operation, the booster set must be connected 
to a diaphragm tank (or bladder tank). The tank volume can be 
optimised according to the pumping condition. Furthermore, the 
volume can be distributed on several tanks, e.g. two 24-litre tanks 
on the discharge manifold and a customised tank on the floor.

The optimised tank volume can be calculated from the following 
formula:

V =

Tank volume [litres].

Q =

Mean flow for one pump [m

3

/h].

Δ

p =

Difference between cut-in and cut-out pressures.

Cut-in = Cut-in pressure [bar].

= 100.

k =

Constant for diaphragm tank (or bladder tank)
precharge pressure: k = 0.9.

5.7 Priming

Do not start the pumps until they have been filled with liquid. 
See installation and operating instructions for CHV pumps.

Start-up is carried out according to section 

7.

5.8 Electrical connection

The electrical connection should be carried out by an authorised 
electrician in accordance with local regulations.

The wiring diagram and motor labels show required values for the 
electricity supply.

Single-phase versions:

In single-phase versions, a built-in thermal switch protects the 
motor. If required according to local regulations, an additional 
motor protection must be installed.

The mains supply cable with the leads L1, N and PE must be 
connected to the CS 201 controller:

L1 and N to main switch terminals and 

PE to terminal 

.

Three-phase versions:

No additional motor protection is required as the CS 203b 
controller incorporates an automatic circuit breaker.

The mains supply cable with the leads L1, L2, L3 and PE must be 
connected to the CS 203b controller:

L1, L2 and L3 to main switch terminals and 

PE to the terminal located at the earth bar/plate.

Caution

The booster set is not designed to support more 
than one 24-litre tank mounted on the discharge 
manifold. One more 24-litre tank on the discharge 
manifold is optional. If two tanks are mounted on 
the manifold, additional supports/pipe hangers 
are required.

Warning 

Before making any connections in pumps, 
terminal boxes or control cabinet, the power 
supply must be switched off.
