INSTALLATION
REFRIGERANT LINES
For more information about the refrigerant line, please request the ref. 207682 document.
Refrigerant circuit
It is extremely important to design the refrigerant lines correctly between the indoor and the outdoor units. The
following criteria shall be taken into account when completing that task:
The line pressure drop.
The refrigerant circulation speed.
The refrigerant mass in the system.
The length of the interconnection pipes (please contact Hitecsa for lines longer than 50 meters).
Discharge lines
In the heating mode: the suction line becomes the discharge line.
Line design
Only Cooling Units / Heat Pump Units
The indoor unit is placed at a lower level than the outdoor unit: siphons are not necessary in the vertical section
(However we recommend to include one every 6 to 9 meters in order to make the oil return quicker for start-ups).
Handling when the unit is working: the discharge line temperature is HIGH, beware of burning risks!
ATTENTION!
