2.3 INSTALLATION DIAGRAMS

The indoor unit may be installed on top of the outdoor one and vice versa.
Outdoor unit positioned at the bottom and indoor unit at the
top ("fig. 4 -").
In this case a trap (6) must be made on the intake piping (3) to
halt the downflow of refrigerant and to avoid liquid returning to the
compressor. The relative connection pipes
must be insulated.
Key:
1. Outdoor unit
2. Indoor unit
3. Piping on gas side (larger diameter)
4. Piping on liquid side
5. Condensation drain pipe
6. Trap
Outdoor unit positioned at the top and indoor unit at the bot-

In this case, traps (6) must be installed on the suction piping (3),
every three meters of difference in level. These traps will allow
the oil to return to the compressor. The relative connection pipes
must be insulated.
