    REGULATIONS, RECOMMENDATIONS AND WARNINGS 1.1. Regulatory compliance This outdoor unit has been designed in compliance with the regulations in force, and must be used within the framework of those regulations. In particular, it complies with the Machinery Directive, the Pressure Equipment Directive, and the Electromagnetic Compatibility Directive.
  • Page 6 In the event of a dispute, write to the carrier within 48 hours mentioning all reserves and send a copy of this letter to the SATC department of the Ideal Heating. Before unpacking the appliance, check that there are no refrigerant leaks using a suitable detector.
  • Page 7 Designation R290 INDICATION OF DANGERS Main dangers: Highly flammable and explosive class A3 fluid. R290 vapours are heavier than air and can cause asphyxiation due to an oxygen concentration level reduced to a level at which the fluid can stagnate. Specific dangers: Contact with R290 fluid in liquid form can cause frostbite. FIRST AID MEASURES General information In case of a high concentration, the fluid can cause asphyxiation. Loss of mobility and/or consciousness are characteristic symptoms. A narcotic effect may be observed at a lower concentration level.
  • Page 8 Storage Close tightly and store in a cool, dry, well-ventilated place. Keep in original recipients. Storage containers should be checked periodically. Do not store with other oxidising elements or other combustible materials. All electrical/electronic equipment located in the storage area must be compatible with the risk of the formation of an explosive atmos- phere (ATEX).
  • Page 9 Warning specific to the R290 refrigerant This appliance functions with class A3 R290 fluid (ASHRAE classification 34). In the event of a leak, the diffusion of R290 into the environment can lead to the formation of a highly flammable and explosive atmosphere.
  • Page 10 Draining and charging refrigerant Refrigerant gas draining, charging and recovery procedures may only be performed by specialised technicians or qualified personnel who have received adequate training in the handling of flammable gas, have specific skills, and comply with local laws. The refrigerant charging procedure is described in paragraph 3.6.7. of this document. Below is a list of safety precautions that is not necessarily exhaustive: Ensure that no other substance is contaminating the R290 fluid.

  • Page 86 ECOMOD-23/27 - Installation, Use and Maintenance 7.8. “Maintenance” check list ■ Before starting any work on equipment containing flammable refrigerant, safety checks must be performed to minimise the risk of ignition. Take the following steps before working on the cooling system: Measure Performed Comment General working environment ■ Inform all of the following persons of the type of work to be carried out: –...
  • Page 87 Only replace defective components with original parts. ■ Replace the components according to the instructions in the manual. Where necessary, call on the Ideal Heating's technical department. Carry out the following checks: ■ The refrigerant load must not exceed that allowed for the installation room.
  • Page 88 ■ Only components suitable for a flammable atmosphere may be powered up in the vicinity of such an atmosphere. ■ Use only suitable original parts or components approved by the Ideal Heating. Other components may cause the refrigerant to ignite if leaked. Wiring ■ Check if the wiring is subject to wear, corrosion, traction, vibrations, sharp edges or other unfavourable surrounding influences.
  • Page 89 Installation, Use and Maintenance - ECOMOD-23/27 Measure Performed Comment ■ The refrigerant detector must be suitable for the R290 refrigerant to be detected. ■ The refrigerant detector must not contain any potential source of ignition. ■ Calibrate the refrigerant detector to suit the refrigerant used. Set the response threshold to < 3 g/a, suitable for propane. Leak detection using leak detection liquids: ■ Leak detector liquids associated with most refrigerants are suitable.
  • Page 90 ECOMOD-23/27 - Installation, Use and Maintenance Measure Performed Comment Topping up the refrigerant Filling with refrigerant In addition to the usual filling procedure, the following requirements must be satisfied: - make sure that the filling valve is not used for different refrigerants. The pipes should be as short as possible to minimise the amount of refrigerant contained. - the refrigerant bottles must remain in a vertical position. - make sure the refrigerant circuit is earthed before filling it.
  • Page 91 Installation, Use and Maintenance - ECOMOD-23/27 Measure Performed Comment j) If the recycling bottles are filled as required and the process is completed, ensure that the bottles and equipment are immediately removed from the facility and that all shut-off valves are closed. k) Recovered refrigerant must not be used to fill other systems until it has been purified and examined. Marking (on the heat pump) If the heat pump has been taken out of service, affix the following marking, along with the date and signature, prominently on the heat pump: ■ The refrigerant is inflammable.
