further reason may be triggering of the solenoid valve to shut down the system. The flow meter may trigger
an alarm and enable immediate operator intervention.
On no account may the total pressure loss of the system exceed a value above that of the pump performance.

Another option for directly filling the tank involves attaching a T-fitting to the cooling medium outlet fitting in
♦
order to connect the cooling medium circuit with a supply pipe. This is used to fill the chiller. We also recom-
mend connecting a valve to the supply pipe in order to stop the flow when the tank is full or to restart the
flow as soon as a top-up is necessary.

CONNECTION TO THE ELECTRICITY MAINS
The properties of the electricity mains (size, protection system, earth connection) must comply with the
legislation applying to the electrical properties of the chiller in the country in which it is installed.
The general regulations pertaining to installation are listed below.
The electrical installation may only be carried out by qualified personnel!
The mains connection should be established with a rubber-sheathed cable connected to a TN-C system
with direct earthing.
230 V version (1 phase):
Connection with a single-phase, three-wire system (1/N/PE AC). The phase conductor and the neutral
conductor must be connected directly to the main switch of the chiller.
The protective earth conductor must be connected to the earthing point of the chiller.
400 V version (3 phase):
Connection with a three-phase, four-wire system (3/PEN AC). The three-phase conductor must be con-
nected directly to the main switch of the chiller. No neutral conductor is used. The PEN must be connect-
ed to the earthing point of the chiller.
If different mains voltages and frequencies are available, the country-specific features must be observed.
Make sure that the mains voltage and the frequency match the data on the identification plate of the
chiller and agree with those in the table in the supplement and that the permitted values are not exceed-
ed. Check the mains for correct values and test the function of the earthing and protection systems.
Install a general isolating switch for the electricity mains close to the chiller. The connecting circuit for the
chiller must be equipped with a circuit breaker and residual current protective device.
You can find information on the electrical power input values for the chiller in the supplement.
Before you connect the chiller to the mains, make sure that the general isolating switch disconnects the
chiller from the electricity mains.
Pass the wires in the flexible polymer cable gland in the control panel (see photo for position) to connect
the power cable. Feed the connecting lead through the aperture in the rear plate (CHW 29 - CHW 145) on
the base of the chiller. Lay the cable on the upright up to the gland on the base of the switch cabinet
(CHW 162 - CHW 3652). Inside the switch cabinet lay the cable in the installation duct up to the main
switch, where it is connected directly.
Check that the screws on the terminal clamps are firmly seated!
