3.0 Installation
10 CC1132751C
If the compressor is located a long way from the isolator and/or
the ambient temperature exceeds 35°C (95°F), the cable size
should be increased.
Check that the transformer fuse is positioned to suit the supply
voltage of the installation.
Ensure all electrical connections are tight, high voltage supply to
contactors and incoming terminals are critical.
Close the starter door and secure with the key provided before
replacing the main line fuses.

3.6 Compressor Rotation
CAUTION !
BEFORE INITIAL START-UP ENSURE THE
COMPRESSOR IS FILLED WITH A HYDROVANE
APPROVED OIL. DO NOT OVERFILL OR MIX
OILS.
With the mains isolator on, press the green start button on the
control panel and watch the pressure gauge.
Rotation is correct if the pressure display rises immediately, after
a few seconds if no pressure is displayed rotation is incorrect.
WARNING !
SERIOUS DAMAGE WILL OCCUR IF THE UNIT
IS ALLOWED TO RUN IN REVERSE. IF
ROTATION IS INCORRECT, STOP AND ISOLATE
FROM THE ELECTRICAL SUPPLY.
Open the starter door and change over any two of the incoming
cables connected to the starter terminals L1, L2 and L3.
Close and lock the starter door to prevent unauthorised access
and switch the mains electricity supply on.
Restart the compressor and verify that direction of rotation is
correct by observing pressure rise on the compressor gauge.
Cooling fan operation is clockwise, all RS units have automatic
stop/start cooling fans that cut in at 85°C (185°F) operating
temperature.
Remove the cabinet filter from the lower half of the rear panel to
view the cooling fan through the mesh grill.
3.7 RS Operation with other Compressors
Hydrovane RS compressors may be operated efficiently in
conjunction with other Hydrovane compressors fitted with
automatic stop-start control.
Adjust the RS minimum air line pressure to midway between the
maximum and minimum air line pressure settings of the other
compressor. The RS compressor will automatically assume the
lead compressor role after several cycles.
NOTE !
If the RS compressor is operated with other Hydrovane
standard single speed compressors feeding a common pressure
system, the minimum air line pressure of the RS compressor
must be limited to the lowest maximum air line pressure of the
single speed machine(s). No attempt must be made to increase
the operating pressure of the single speed machine(s).
The pressure transducer sensing point is located in a filter
housing adjacent to the outlet from the compressor. If the
pipework from the compressor to the system is restricted, or
prone to excessive pressure fluctuation, rapid speed changes
and/or frequent stopping and starting of the motor may occur.
Should this condition arise, consult a Hydrovane Distributor who
will arrange to re-site the pressure transducer location.
