The PIC5+ software version number of your 19DV unit will be located on the HMI module.
Information on the unit control is not included in this manual. Refer to separate controls manual.
2.3 Chiller technical documentation (wiring diagram, dimensional
drawings, PID)
All figures, chiller view, and schematics of the IOM documents are not contractual not-certified drawings. Please
refer to the certified drawings and electrical diagrams supplied with the unit or available on request, when
designing and installation.
Weight and dimensions are not-certified and only indicative data. Please refer to certified drawings of the selected
chiller.

2.4 CE marking

19DV chillers with CE marking have been designed and manufactured according to the following European
directives:
- Pressure Equipment Directive 2014/68 / EU, by application of harmonized standard 378-2 Refrigeration
and heat pump systems Safety and environmental requirements
- Machinery Directive 2006/42 / EC, by application of Harmonized Standard 60204-1: Safety of machinery -
Electrical equipment of machines - Part 1: General rules
- Electromagnetic compatibility (EMC) 2014/30 / EU by application of harmonized standard 61800-3 for
variable speed drives.
The electromagnetic emission and immunity levels comply with the requirements for an industrial environment and
are not designed for operation in a residential environment.
This equipment uses and can emit radio energy. In the event of installation or use not in accordance with the
instruction manual, interference with radio communications may occur.

2.4.1 CLASSIFICATION

In accordance with the requirements of the Pressure Equipment Directive and the national regulations, the safety
accessories of the unit are classified as follows:
Refrigerant circuit
Safety contactor
Relief valves (3)
Coolant circuit
Relief valves
(1) Classification for protection in a normal service situation.
(2) Classification for protection in a abnormal service situation. These accessories are fire sized for a thermal flux
of 10kW/m2. No combustible material should be within 6.5m of the unit.
(3) The momentary overpressure limited to 10% of the service pressure does not apply to this abnormal service
situation.
The set pressure may be above the operating pressure. In this case, the failure to exceed the operating
pressure under normal operating conditions is ensured either by the design temperature or by the high
pressure switch.
(4) The classification of these valves must be done by the integrators who carry out the entire hydraulic
installation.
The unit is equipped with a safety loop, also called measurement, control and regulation devices playing a role in
safety (SRMCR for protection against overpressure that could be created by the compressor).
Made of :
- 2 active pressure switches (HPS) at compressor discharge
- Safety relay inside the control cabinet
- Power contactor inside the VFD
- VFD
This SRMCR is designed in accordance with EN ISO 13849-1: 2016 according to the following characteristics:
- PL d
- Category 3.
- Mission duration 20 years.
