Installation manual /eCOMFORT-MIL150E-0916 / 05/2017

All units are compliant with the following Directives, Norms and Standards:

• 2014/68/EU Pressure Equipment Directive

• 2006/42/CE Machinery Directive

• 2014/35/EU Low Voltage Directive

• 2014/30/EU Electro Magnetic Compatibility Directive

• EN378-1-2 :2009 -3-4- Refrigerating systems and heat pumps - Safety and environmental requirements

• 2011/65/EU The European Restriction of the Use of Certain Hazardous Substances (RoHS)

• « WEEE », 2012/19/EU –Directive on waste electrical and electronic equipment

• 2009/125/EC Ecodesign • EN-378-1-2:2009-3-4. • EN-60204-1. And is provided with CE markings (on the condition
that the necessary options are present) (for further information see EU declaration).

SAFETY RELIEF

This equipment is protected with safety pressure relief calibrated at 42,7 bar g and safety pressure switch calibrated at 42
bar g. Do not overcome this operating pressure.

IMPORTANT NOTICE
All work on the unit must be carried out by a qualifi ed and authorised employee.

Non-compliance with the following instructions may result in injury or serious accidents.

Work on the unit:

• The unit shall be isolated from the electrical supply by disconnection and locking using the main isolating switch.

• Workers shall wear the appropriate personal protective equipment (helmet, gloves, glasses, etc.).

Work on the electrical system:

• Work on electric components shall be performed with the power off (see below) by employees having valid electrical
qualifi cation and authorisation.

EMC DIRECTIVE COMPLIANCE
WARNING:

This equipment is an “A class“ according CEM Directive. In an industrial environment, this device can create radio electri­cal noise. In this case, the owner can be asked to take appropriated actions.

This applies to all machine installed with nominal amps below <75A:

• The short-circuit rate Rsce=33 is defi ned in the EN61000-3-12 standard relative to the harmonics readings on the
supply network. The appliances compliant with the harmonic current limits equivalent to Rsce=33 can be connected in
whatever connection point of the main supply system.

• The maximal allowable impedance of the main supply system Zmax=0.051W is defi ned by EN 61000-3-11 standard
relative to the voltage variation, fl uctuation and fl icker readings. The connection to the supply is a conditional connec-
tion submitted to the preliminary agreement of the power supply local provider.

Work on the refrigerating circuit(s):

• Monitoring of the pressures, draining and fi lling of the system under pressure shall be carried out using connections
provided for this purpose and suitable equipment.

• To prevent the risk of explosion due to spraying of coolant and oil, the relevant circuit shall be drained and at zero
pressure before any disassembly or unbrazing of the refrigerating parts takes place.

• There is a residual risk of pressure build-up by degassing the oil or by heating the exchangers after the circuit has
been drained. Zero pressure shall be maintained by venting the drain connection to the atmosphere on the low pres­sure side.

• The brazing shall be carried out by a qualifi ed brazer. The brazing shall comply with the standard NF EN1044
(Minimum 30% silver).

Replacing components:

• In order to maintain CE marking compliance, replacement of components shall be carried out using spare parts, or
using parts approved by LENNOX.

• Only the coolant shown on the manufacturer’s nameplate shall be used, to the exclusion of all other products (mix of
coolants, hydrocarbons, etc.).

CAUTION: In the event of fi re, refrigerating circuits can cause an explosion and spray coolant gas and oil.

PED DECLARATION

Installation manual /eCOMFORT-MIL150E-0916 / 05/2017

F GAS REGULATION

Operators of refrigeration equipment’s must comply with the obligations defi ned in:

- EU Regulation No 517/2014 on fl uorinated greenhouse gases

- EC 1005/2009 on substances that deplete the ozone layer

Non compliance with these requirements is an offence and liable of fi nancial penalties.

Moreover, in case of problem it is mandatory to prove to the insurance company that the equip­ment complies with the F gas Regulation

Installation manual /eCOMFORT-MIL150E-0916 / 05/2017

1. Attention: The high-pressure safety switches are essential elements which guarantee the system remains within the

admissible operating limits. Before switching on the installation, always ensure all electrical connections are correct on these
elements which are used to isolate the electrical power supply to the compressor(s) they protect. Carry out a test to ensure
the electrical power supply is effectively isolated when the pressure switch attains its set value.

2. In case of installation in a seismic zone or in a zone which may be effected by violent natural occurrences such as storms,
tornados, fl oods, tidal waves, etc…, the installer and/or operator will refer to valid standards and regulations in order to ensure
the devices required are available as our units are not designed to operate under such conditions without prior precautions.

3. The equipment is not designed to resist fi re. The installation site will therefore have to respect valid standards with regard to
protection against fi re (emergency instructions, map…).

4. In case of exposure to corrosive external atmospheres or products, the installer and/or operator shall take the necessary
precautions to avoid damage to the equipment and will make sure the equipment provided has the necessary and suffi cient
anti-corrosion protection.

5. To respect a suffi cient number of supports for the piping according to their size and weight under operating conditions and to
design the piping to avoid a water hammer phenomenon

6. For technical reasons, it is not possible to carry out hydrostatic tests on all our units so leak tests are carried out as a
compensatory measure. (The entire circuit is checked using leak detectors). For machines charged with refrigerant, at the end
of the test, an HP test is carried out in the factory to make sure the pressure switch is working properly.

7. Before any work is carried out on the refrigeration circuit, the dry air or nitrogen pressure our units are supplied with must be
released (For units not charged with refrigerant in the factory.)

8. The emissions of refrigerant via the safety relief valves must be channeled to the exterior of the machine room. The outlet
relief valve will have to be sized in compliance with EN13136.

9. Installation and maintenance of these machines must be carried out by personnel qualifi ed to work on refrigeration equipment.

10. All interventions must be carried out in conformity with valid safety regulations (e. g.: NF EN 378), as well as the recommendations
indicated on the labels and handbooks provided with the machine. All actions shall be taken to avoid access of unauthorized
persons.

11. It is essential that any pipework or other components of the refrigeration circuit hazardous to people because of their surface
temperature are insulated or identifi ed.

12. Ensure that the installation zone (room or area) of the machine has restricted access and ensure the good condition of the
covering.

13. The risk of inadvertent discharge is minimized.

WARNING

1.2 - Warning labels

The chiller is marked with the following warning labels to alert to potential hazards (on or near the potentially hazardous part).

Regularly check that the warning labels are still in the correct positions on the machine and replace them if necessary.

1.- GENERAL CHARACTERISTICS

1.3.- COMPONENTS

The eComfort system comprises a water cooler or air/water pump combined with a series of hydraulic accessories.

The use of a water fi lter in the water circuit upstream of the heat exchanger is mandatory. These fi lters must remove all particles with a diameter greater than 1 mm, and must
be positioned within 1 meter of the inlet of the exchanger. They may be supplied as an option by the manufacturer.
