Cooling Connections Indoor Unit - Ferroli OMNIA H Series Installation, Maintenance And User Manual

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.
Comply with the limits given in the following tables.

Cooling connections indoor unit

Comply with the following indications when connecting the cooling pipes:
• Match the ends of the previously flared pipe with those of the connections on the indoor units or on the cocks of the outdoor units.
• Tighten the union by hand and then torque it with the aid of an adequate wrench (it is advisable to use a fox wedge to prevent
tensions from being created on the pipes).
