Pipe lines should be as short as possible and any unnecessary changes in direction and incline should be avoided.
To prevent heat loss, the two lines should be insulated separately.
Use a suitable tool to bend the tubing and avoid kneading the cooling tubes.
Secure the pipe with specific clamps and make sure any eventual pipe vibration, can not be transmitted to the construction structure.
Never use tubing of unknown origin, you MUST use special, dioxidated and dehydrated copper refrigeration tubing.
To avoid changing the capacity of the units, make sure that the pipe length and elevation changes are kept to a minimum.
Select copper tube diameters according to the size of the unit to be installed.
Before connecting the cooling lines, follow the procedures below:
- Install the cooling lines, making sure that foreign bodies do not enter the piping.
- Connect the tubing to the valve connection that is supplied
vacuum the tubing to 300 μm Hg. This operation must be followed by a leak test using a vacuum pump.
- Fill in the refrigerant charge if necessary.
