Diameter Of The Water Connections; Electrical Connections - CIAT aquaciat 2 LD Serie Handbuch

IMPORTANT: To prevent any risk of fouling or damage to the
plate exchangers, it is essential to install a screen filter at the
water inlet. This should be as close as possible to the
exchanger and in a location which can be easily accessed for
disassembly and cleaning. The meshing of this filter will be no
greater than 600 µm (see option in price list)
IMPORTANT: It is essential to use flexible connectors on
hydraulic pipes.
IMPORTANT: The use of untreated or inadequately treated
water may result in scaling or deposits of algae or mud or may
lead to corrosion or erosion. CIAT cannot be held responsible
for any damage resulting from the use of untreated or
inadequately treated water or saline or brackish water.

Electrical connections

● The units have been designed to comply with European
standard EN 60204-1.
● They comply with the machinery and EMC directives.
● All cabling must be undertaken in compliance with the
regulations applicable at the installation site (in France,
NF C 15100).
● In all cases, you should refer to the wiring diagram supplied
with the unit.
● Respect the power supply characteristics indicated on the
type plate.
● The voltage must be in the indicated range:
+ 10 %
– Power circuit: 400 V
- 10 %
* 230 V
* Installation subject to regulations in France
● The phase unbalance must not exceed 2% for the voltage
and 10% for the current.
If one of the above conditions is not respected, contact your
energy provider immediately and make sure that the unit is not
activated until corrective measures have been taken. If this is
not done, the CIAT guarantee will be automatically invalid.
The dimensioning of the cables must be performed by the
installer as a function of the characteristics and regulations
specific to the installation site. After selecting the cabling, the
You are required to protect your unit against overvoltages which may be due either to the power supply network or to atmospheric causes.
Depending on the geographical location of the site and the type of network (underground or overhead); local regulations may require the presence
of a lightning arrestor. The CIAT guarantee shall cease to apply in the event of any failure to comply with applicable standards in the country of
installation (NF C 15100 in France).

NOTE: the maximum working pressure on the water side is 10
bars for LD-ILD and 4 bars for LDC-LDH-ILDC-ILDH.
- The water flow detector is supplied mounted in the unit.
If the hydraulic circuit has to be drained for a period longer
than a month then it is necessary to fill the entire circuit
with nitrogen in order to avoid any risk of corrosion.
IMPORTANT: If the circuit is not protected by an antifreeze
solution and the unit does not run during periods of frost then
it is obligatory to drain the evaporator and the external piping.

installer must define any adaptations which may be necessary
on-site in order to facilitate connection.
● Cables must be chosen as a function of:
– The maximum nominal current (refer to the "Electrical
characteristics").
– The distance between the unit and the power supply source.
– The protection provided at the source.
– Neutral running conditions.
– The electrical connections (refer to the wiring diagram
supplied with the unit).
● The electrical connections should be established as follows:
– Connection of the power circuit
– Connection of the shielding conductor at the earth terminal.
– Possible connections of potential-free contact for signalling
general faults and the automaticity control.
– Automatic control of compressors by the operation of the
circulating pump.
● The automaticity control must be connected via a completely
potential-free dry contact.
● The isolator has a cut-off capacity of 50 kA up to model 700
and 100 kA from model 702 to 1100.
● The switch handle is supplied in the electrical panel to
prevent it being broken during transport. It is your responsibility
to mount it on the door.
