• 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.).
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 equip- ment complies with the F gas Regulation Installation manual /eCOMFORT-MIL150E-0916 / 05/2017...
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). High temperatures Electrical Voltage Rotating parts Sharp parts Regularly check that the warning labels are still in the correct positions on the machine and replace them if necessary. WARNING Attention: The high-pressure safety switches are essential elements which guarantee the system remains within the admissible operating limits.

2.- INSTALLATION 2.7.- UNIT INSTALLATION 1. The eComfort units could be installed outside or inside. 2. See the minimum clearance diagrams for access - air supply to the batteries in the heating section of the unit (see page 25). 3. Assemble the unit on a resistant base, preferably concrete. To prevent vibrations, the concrete base should not come into contact with the building’s foundations.
Page 48
2.- INSTALLATION For location inside, keep in mind following advice: - In heat pump units during defrost cycle, the units produce a great amount of water melting the ice off coils. If you wish to drain the water, adequate drainage should be installed below the unit to collect and carry out the water where desired.
2.- INSTALLATION 2.8.-ELECTRICAL CONNECTIONS - BEFORE MAKING ANY ELECTRICAL CONNECTIONS, BE SURE THAT ALL CIRCUIT BREAKERS ARE OPEN AND SUPPLY IS OFF. - IN ORDER TO CARRY OUT THE ELECTRICAL CONNECTIONS, FOLLOW THE ELECTRICAL DIAGRAM SUPPLIED WITH THE UNIT.

2.- INSTALLATION 2.9 -PARTIAL HEAT RECOVERY OPTION The aim of the Partial Heat Recovery (PHRF) is to recover temperature heat from the compressor discharge gases by means of a condensing water heat exchanger. The heat recovery capacity depends on the operating conditions (the compressor discharge temperature comes from the HP/LP ratio), on the number of compressor running, on the water fl...
3.- COMMISSIONING AND OPERATION LENNOX REFAC, S.A. Designs and develops its machines always looking for the greater comfort and well-being of its custo- mers and users, at the same time as the greater energy effi ciency of the elements that constitute the units. This effort would be fruitless if it was not united to a responsible use of these equipment.

3.- COMMISSIONING AND OPERATION 3.3.- CHECKING THE WATER FLOW RATE It is very important that the unit operates at the correct water fl ow rate. It is dangerous to leave the unit operating at a low fl ow rate as this could result in serious damage to components as well as the water exchanger. If the unit operates at too high a fl...
3.- COMMISSIONING AND OPERATION 3.4.- WATER ANALYSIS The water must be analysed; the water circuit installed must include all items necessary for treaent of the water: fi lters, additives, intermediate exchangers, bleed valves, vents, isolating valves etc... depending on the results of the water analysis. We do not advise operation of the units with open loops which can cause problems with oxygenation, or operation with untreated ground water.
4.1.- PREVENTIVE MAINTENANCE PREVENTIVE MAINTENANCE PREVENTS COSTLY REPAIRS. We recommend regular and thorough servicing of the LENNOX unit. It is therefore advisable to ask your dealer about maintenance contracts. Check maintenance of the following points (depending on the operating conditions maintenance every 6 months may be necessary).

4.- MAINTENANCE 4 3- CLEANING THE CONDENSER 4.3.1 - Air cooled condensers Clean the coils either with a vacuum cleaner, cold water, compressed air, or with a soft brush (non metallic). On units installed in a corrosive aosphere, coil cleaning should be part of the regular maintenance program. On this type of installation, all dust gathered on the coils should be quickly removed by regular cleaning.
