Pressure gauges
The ROKLIMA PLUS 4F unit is equipped with 3xØ80mm
pressure gauges (depending on the model) with different
scales of coolant, dry regulated, with “Pulse Free”
braking movement that keeps the reading index free of
vibrations.
Flexible tubes
The ROKLIMA PLUS 4F unit is equipped with 3x2500 mm
flexible tubes (depending on the model) with intermediate
valve.
Their flexibility assures maximum ease of connection in
any situation; their role is to support the working pressures
from the A/C installation and maintain the flow section
intact even when working at low pressure.
Scales
The ROKLIMA PLUS 4F unit is equipped with an electronic
scale reading up to 100 Kg.
Programming system

the power cable.
- Place the bottle in the centre of the scales plate and
connect the capillary tube No. 10 to the bottle's liquid
intake, using the appropriate included reducer.
- Select the pressure gauge with the scale for the desired
coolant and connect it to coupling no. 9
- Select the flexible tube with the appropriate connections
for the system on which we are working and connect it
to connection no. 1
- Connect the flexible tube to the A/C system
4.2. How to use the Control panel
Thanks to the microprocessor and the electronic scale,
the ROKLIMA PLUS 4F unit is fully managed through a
computerised system, and can be controlled through the
buttons in the front panel. The ROKLIMA PLUS 4F unit
has a good-sized control panel for easy reading, even in
the poorest lighting conditions, thanks to its back light
system; the control panel enables the reading of the
parameters linked to the selected function and, if an
error should occur, it marks the appropriate error code.
