CCHIBA/CSTIBA
SPLIT HORIZONTAL INVERTER UNITS
PACKAGED AIR-AIR
In addition to refrigerant, sometimes
it’s necessary to add oil. For more than 25 meters, add 30 grams.
If liquid line is descendant and there is a considerable height difference, you have to compensate the excess pressure
before the expansion.
If liquid line is ascendant and there is a considerable height difference, the formation of gas refrigerant before the
expansion must be avoided.
If you do not find the right pipe diameter, you can use the immediately lower diameter. The system will function
normally only with a slight capacity reduction.
Units CSTIBA/CCHIBA are supplied with nitrogen charge at a pressure between 5 and 6 bar. Before proceeding
to any welding work, it’s necessary to remove this charge out of the circuit. Once you have finished, only qualified
and trained service staff can make the vacuum and charge with the right amount of refrigerant.
It is forbidden by law to expel refrigerant into the atmosphere; therefore, it is
necessary to recover all the refrigerant and to avoid leaks.
Units without valves come loaded with nitrogen pressure leak test. Drain with
caution previously the realization of unions.
