It is recommended to realize the refrigerating lines
with perfectly vertical or horizontal strokes.
Maximum pressure of use:
The emassimo pressure value during use is 1.72 MPa (250 psig). (R410A)
Line insulation:
•
The connection fitting to the indoor unit must be wrapped in thermal
insulation. There must be no cracks between the fitting and the wall of the
indoor unit.
•
After having wrapped the tubes with protective material, never bend them at
an acute angle as they may crack or break.
•
Use adhesive tape to cover the pipes:
•
Use adhesive tape to wrap the connection pipe and cables together. To prevent
condensation from escaping from the drain pipe, separate the drain pipe from
the connecting pipe and cables.
•
Use thermal insulation tape to wrap the pipes from the bottom of the outdoor
unit to the upper end of the pipe where it enters the wall. When using
insulating tape, the last lap must cover the first lap of tape in half.
