system or isolated (by way of shut-o valves) in part of the system located away from the leak.
Removal and discharge
• When accessing the cooling circuit to carry out repairs, or for any other reason, convenonal procedures must be
employed. However, for ammable refrigerants, the recommendaons must be complied with in order to take
account of the product’s ammability. The following procedure must be followed:
- remove the refrigerant;
- purge the circuit with an inert gas (oponal for A2L);
- drain (oponal for A2L);
- purge with an inert gas (oponal for A2L);
- open the circuit by cung or soldering.
• The refrigerant charge must be recovered in suitable recovery cylinders. For appliances containing ammable
refrigerants other than A2L refrigerants, the system must be bled with nitrogen devoid of oxygen to make the appliance
suitable for receiving ammable refrigerants. You may need to repeat this process several mes. Compressed air or
oxygen must not be used to purge cooling systems.
Loading procedures
• Check that the vacuum pump outlet is not located in the vicinity of any potenal ignion source and that venlaon
is provided.
• In addion to convenonal charging procedures, the following requirements apply.
- Check that there is no possibility of cross-contaminaon between the dierent refrigerants when using charging
equipment. Hoses or lines must be as short as possible to reduce the quanty of refrigerant contained therein.
- Cylinders must be kept in an appropriate posion, in accordance with the instrucons.
- Check that the cooling system is grounded before charging the system with refrigerant.
- Label the system once charging is complete (if this is not already the case).
- Pay close aenon to not overlling the cooling system.
• Before recharging the system, carry out a pressure test using a suitable purge gas. The system must be examined to
make sure there are no leaks aer the charging operaon and before commissioning. A follow-up leak test must be
carried out before leaving the site.
Dismantling
• Before dismantling, the technician must familiarise himself/herself with the equipment and its specicaons. We
highly recommend carefully recovering all refrigerants. Before this, oil and refrigerant samples must be taken if
analyses are to be carried out before any other use of the recovered refrigerant. Check for the presence of a power
supply before starng work.
5. Familiarise yourself with the equipment and how it operates.
6. Electrically isolate the system.
7. Before starng work, check the following points:
- mechanical handling equipment is available if needed to handle the refrigerant cylinders;
- all personal protecve equipment is available and used correctly;
- the recovery process is followed at all mes by a cognizant person;
- the recovery cylinders and equipment comply with the relevant standards.
8. Drain the cooling system where possible.
9. If a vacuum cannot be created, install a manifold in order to be able to remove the refrigerant from various locaons
within the system.
10. Make sure that the cylinder is located on the scales before starng recovery operaons.
11. Start the recovery unit and operate as per its instrucons.
12. Do not overll the cylinders (no more than 80% of the volume must be lled with liquid).
13. Do not exceed the maximum working pressure of the cylinder, even temporarily.
14. When the cylinders have been lled correctly and the process is complete, check that the cylinders and the
equipment are quickly removed from the site and that the alternave shut-o valves on the equipment are closed.
15. The recovered refrigerant must not be charged in another cooling system, unless it has been cleaned and inspected.
3.2.2 User maintenance
• Clean your pool and the water system regularly to avoid the damage of the unit.
• Clean the evaporator using a so brush and a fresh water spray (disconnect the power cable); do not fold over the
metal wings, then clean the condensate drainage line to remove any impuries that may be blocking it.
• Do not use a high pressure jet. Do not spray with rain water, salt water or water which is full of minerals.
• Clean the outside of the appliance; do not use any solvent-based products. We can provide you with a specic cleaning
kit as an accessory: the PAC NET, see § “5.1 I Descripon”.
3.2.3 Maintenance to be carried out by a qualied technician
• Check that the control system is operang correctly.
• Check that the condensates ow correctly when the appliance is in operaon.
• Check the safety mechanisms.
• Check the connecon of the metal masses to the earth.
• Check that the electrical cables are correctly ghtened and connected and that the switch box is clean.
