"This unit can be delivered with the R134a refrigerant or R600a / R290. To find out the type of
refrigerant and the burden you see the identification of the unit".
The iso-butane refrigerant (R600a) and the propane (R290) have the following benefits:
• High energy efficiency.
• Ozone depletion potential (ODP): 0
Global warming potential (GWP): Minimum
•
The refrigerant R600a and the R290 are highly respectful of the environment, but are also a fuel gas, so it is necessary
to take precautions when handling the equipment.
Security measures:
• Avoid handling or damage any component of the refrigeration circuit.
• Never use mechanical means to accelerate the defrosting process. Avoid any other means not recommended by the
manufacturer.
• Keep the front protective grille mounted.
• Perform the cleaning of the equipment carefully, using the heat exchangers a soft brush, compressed air or suitable
suction equipment for not damaging them.
• Place the equipment in a large room, to avoid the possible formation of explosive gas-air mixture in case of leakage.
The room must have a minimum of 1m3 per every 8g of refrigerant charge. You can view the latest data on the
characteristics label.
• Never turn on the unit if you suspect that is damaged, if it produces a strange noise or is malfunctioning. Consult
your dealer or technical service.
• Repairs should always be carried out by qualified personnel using original spare parts of the equipment.
• Before unplugging the cable from the computer, always turn off the computer using the switch on the control panel.
• If you detect leaking gas or liquid in the refrigeration circuit, avoid potential sources of ignition such as flames or
sparks. Do not switch or unplug any electrical appliance and ventilate the room for a few minutes.
Warning:
!The failure of the security measures can cause injury by contact of gas and serious accidents by fire or explosion.
!The irresponsible manipulation of the equipment components can lead to serious accidents.
Important Notice for products that use R600a /
R290 as a refrigerant.
