Introduction; Reception Of The Unit; Guarantee; Safety Instructions - CIAT aquaciat 2 LD Serie Handbuch

Introduction

The AQUACIAT 2 water chillers, whether cooling only series
LD, LDC, LDH or reversible series ILD, ILDC, ILDH , make it
possible to meet the air conditioning and heating requirements
of public and office buildings while also catering for the needs
of industrial processes.
The AQUACIAT 2 LD, ILD units are air condensation liquid
chillers which guarantee reliable, secure operation in the area
for which they have been designed.
All equipment is tested and checked in the factory. All the
equipment is delivered with the full refrigerant load.
The units comply with the standards EN 60-204 - EN 378-2 as
well as with the following directives:
- machines 98/37 EC
- EMC 2004/108/CE
- PED 97/23 EC
-> category 2 (LD-LDC-LDH-ILD-ILDC-ILDH)
All persons responsible for installing units, commissioning
them, operating or maintaining them must be familiar with the
instructions contained in this manual as well as with the
technical characteristics specific to the installation site.

Reception of the unit

Each unit has a type plate indicating the unit's identification
number. Please check the unit's type plate to make sure you
have received the correct model. The identification number
must be specified in any correspondence.
When you receive the unit, please check it for any damage. If

Safety instructions

In order to avoid any risk of accident during installation, start-
up or adjustment, it is essential to pay attention to the specific
characteristics of the equipment, such as:
- Pressurised refrigerant lines
- Presence of refrigerant fluid
- Presence of electrical voltage
Only experienced, qualified personnel are authorised to handle
such equipment.
It is essential to respect the recommendations and instructions
present in this manual and the various diagrams supplied with
the unit.
Since
components,
professional association for details of the regulations
applicable to you as operator or owner of the said pressurised
equipment or components. The characteristics of this
equipment can be found on the type plates or in the regulatory
documentation supplied with the product.
The units are equipped with a fire protection device as
standard.
IMPORTANT: before performing any operation at the unit,
make sure that the power supply has been disconnected at the
general isolator located on the unit's electrical panel.

Location of the unit

The standard use of these units is for refrigeration and there is
therefore no requirement for resistance to seismic activity.
Resistance to seismic activity has not therefore been tested.
Before installing the unit, the installer should verify the following
points:
- The unit must be installed outdoors
- The surface of the structure must be strong enough to support
the weight of the unit.
- The unit must be perfectly level.
- Sufficient space must be left around and above the unit to
permit service and maintenance operations (see the
540 to 1100
dimensional diagram supplied with the unit).
A
- The location must comply with the regulation EN 378-3 and
any other specifications applicable to the installation site.
- The selected location must not be liable to flooding.
- Position the unit above the average snow height in the region
in which the unit is to be installed.
In the case of the reversible units, i.e. ILD, ILDC, ILDH, provide
drainage for defrosting water and provide for the possibility of it
freezing on the ground.
- It is highly recommended to install anti-vibration mounts
between the unit's support and frame as well as flexible
couplings on the hydraulic piping in order to reduce structure-
borne vibrations (see section on Vibration isolation).
- Sound level: our units have been designed to ensure
operation at low sound levels with this type of equipment.
However, it is important when designing the installation to take
account of the external environment with regard to noise
emissions as well the type of building with regard to airborne
and structure-borne sound (vibrations).
Conduct a study with an acoustic engineer.
Important: The ambient temperature must not exceed 50°C
during the unit stoppage cycles.
