4. Presentation - Proper use (Fig. 1)

The HPF (High Power Flexible unit) condenser units have the same functions as the old UCA units with the difference
that the unit may be placed outside thanks to a lightweight waterproof grey casing.
The unit uses a SINGLE Scroll compressor.
Standard characteristics
The standard features of the structure include:
- Compressor
- Condenser coil (∆t 10K)
- Fan(s)
- Liquid tank
- Dehydrating filter
- Liquid sight glass
- Electrovalve
- Painted frames
- Compressor service valve
- High-pressure safety pressure switch in conformity with PED
- Manually adjustable high-pressure pressure switch
- Contactor and thermal protection of the compressor
The standard range of the HPF units goes from 3 to 15 HP with electric power supply 380/50 3 phase for both
Normal Temperature and Low Temperature.
Optional
- Regulation of the fan speed (mechanical and electronic regulator)
- Air filter
- Electric panel with electric and mechanical controls
