2.1 Introduction
WARNING
READ HEALTH AND SAFETY PRECAUTIONS
BEFORE YOU START ANY SERVICE WORK.
Adjustment procedures shown must only be carried out by
authorised persons fully trained and competent in the maintenance
of hydrovane compressors.
If you are not able to carry out the work safely, contact your
hydrovane distributor.
2.2 Oil Temperature
Start the compressor and allow to run for 20 minutes in order to
attain its normal working temperature.
Average running temperature, taken by thermometer in the oil filler
thermal pocket should be approximately 60°C(140°F) above
ambient.
2.3 Air Output (Fig. 2.1)
Screw test nozzle 59634-06 (7 bar/102 psi) or 59634-07 (10 bar/145
psi) into compressor outlet.
Close outlet valve and start compressor (continuous run).
Open outlet valve fully, pressure on gauge should not fall below 6.5
bar/94 psi for a 7 bar machine or 9.5 bar/138 psi on a 10 bar/145 psi
machine.
2.4 Leakage Check
Examine all external seals, gaskets and pipe connections for air or
oil leakage, no leaks are permissible.
2.5 Minimum Pressure Valve (Fig. 2.2)
Close outlet valve and start compressor, open outlet valve fully to
atmosphere.
Check the gauge pressure reading.
When set correctly the gauge should show 5 bar (73 psi) and will
operate satisfactorily between 4 bar (58 psi) and 6 bar (87 psi).
2.6 Safety Valve Lift Pressure (Fig. 2.3) PURS
Safety valves are preset to lift as follows:
07 bar (102 psi) compressor = 08 bar (116 psi).
10 bar (145 psi) compressor = 11 bar (160 psi).
Should the safety valve be faulty it cannot be adjusted and must be
renewed as a complete unit.
2.7 Pressure Control Valve (Fig. 2.3)PUTS/PUAS
Close outlet valve and start compressor (continuous run).
Gauge should read either 7.5/109 psi for a 7 bar/192 psi machine or
10.5 bar/152 psi for a 10 bar/145 psi machine.
Should gauge read differently DO NOT attempt to adjust the valve,
renew as a complete unit.
Note the pressure setting written on valve when reordering.

WARNING
THE FOLLOWING FAULT FINDING PROCEDURE
SHOULD BE CARRIED OUT BY QUALIFIED AND
COMPETENT PERSONS ONLY.
THIS PANEL CONTAINS POTENTIALLY LETHAL
VOLTAGES. UNDER NO CIRCUMSTANCES
SHOULD YOU ATTEMPT TO TOUCH ANYTHING
INSIDE THE CONTROL PANEL, OR ON THE
CONTROL PANEL DOOR UNLESS INSTRUCTED
TO DO SO IN THE FOLLOWING PROCEDURE.
Start compressor
Open the starter panel door
Unscrew terminal 38 and remove the connecting wire.
The compressor drive motor must stop immediately
Without re-setting the starter or disconnecting the mains supply to
the starter re-connect the circuit, terminal 38.
Reinstate the electrical control box cover and front panel
CAUTION
If the above sequence is not achieved then a fault may have
occurred which has damaged the OTC. The compressor must not
be operated until a replacement OTC has been fitted and the above
procedure repeated.
Reinstate all panels

3.1 Introduction
WARNING !
READ HEALTH AND SAFETY PRECAUTIONS
BEFORE YOU START ANY SERVICE WORK.
SERVICING OF THE COMPRESSOR MUST ONLY
BE CARRIED-OUT BY AUTHORISED PERSONS
FULLY TRAINED AND COMPETENT IN THE
MAINTENANCE, MAINS ELECTRICAL SUPPLY

minimum pressure valve.
Renew bonded seal (A) and 'O' ring (B), apply silicon grease before
refitting.
Check piston ©) and valve (D) for wear or damage, renew if
necessary.
Clean filter (E) in white spirit or parafin, apply compressed air to
threaded end of filter, renew if it cannot be cleaned satisfactorily.
Testing of the minimum pressure valve is shown in Section 2.5.
3.3 Pressure Control Valve (Fig 3.2) PUTS/PUAS
Remove the screws that retain the valve cover plate.
Remove pressure control valves (F) and note settings, 7 or 10 bar
(100 psi or 145 psi), renew bonded seals (G)
Renew valves complete if found faulty, ensure new valves have the
same pressure rating as those removed. DO NOT attempt to adjust
or dismantle the valves
