INSTALLATION Make sure there is enough room to do the installation ■ Prepare a water drainage channel around the foundation, to drain waste water from around the unit. ■ If water does not easily drain from the unit, mount the unit on a foundation of concrete blocks, etc.
INSTALLATION Limits to the length and height difference of refrigerant pipes The length of the refrigerant pipes between the indoor and outdoor units must be as short as possible and is in any case limited by compliance with the maximum height difference values between the units. Diminution of the difference in height between the units (H1,H2) and of the pipe lengths (L) will limit the load losses, consequently increasing the overall efficiency of the machine.

SAFETY AND MAINTENANCE General Rules for Maintanance Electrical cabinet At least once a year have qualifi ed personnel carry out a thorough visual inspection of the components of the electrical panel to check ☞ for damaged or incorrectly connected components or cables (check the tightness of the terminal screws). The maintenance is extremely important for the functioning of the system and the regular working of the unit over time.
SAFETY AND MAINTENANCE Disconnection and disposal The system contains lubricating oil and refrigerant gas for which, during the destruction of the units, these fluids will be recovered and disposed of in accordance with the rules in force in the country where it is installed. During the disconnection thus avoid spills or leaks of refrigerant gas and of the plant water if treated with additives or antifreeze substances.
