2.0 Product Information
NOTE !
PLEASE READ CAREFULLY AND PROCEED BY
FOLLOWING THESE INSTRUCTIONS BEFORE
INSTALLATION, OPERATION, MAINTENANCE
OR REPAIR OF THE COMPRESSOR UNIT.
2.1 Health and Safety Precautions
To comply with your responsibilities under the Health & Safety at
Work Act 1974, it is essential that the compressor is operated
and maintained by competent persons in accordance with the
instructions in this handbook.
The standard build of all Hydrovane products are designed to
compress clean, dry, atmospheric air and are not intended for
any other purpose.
The compressor warranty will be invalidated if unapproved spare
parts or oils are used. Using such items may cause the efficiency
and service life of the compressor to be reduced, and could
create a hazardous condition over which Hydrovane has no
control.
Failure to maintain the compressor correctly, or modifying it
without prior approval from Hydrovane, may create a hazardous
condition. This will also invalidate the warranty.
Read and fully understand the contents contained in the User
Handbook, ensure that it is not permanently removed from the
compressor.
Hydrovane declines all liability in the event of material damage
or bodily injury resulting from negligence in the application of
these precautions, from non-observation or lack of elementary
supervision in respect of handling, operation, maintenance or
repair, even if not expressly stated in this instruction notice.
2.2 Compressor Performance
Your compressor will give optimum performance and trouble-free
service life when the bulk oil temperature is maintained between
75-85°C (167-185°F).
Certain operating conditions sustained over a period of time may
cause problems that affect the performance and reliability of this
compressor.
Problems may occur when compressors run for short periods on
low air demand where they don’t reach normal operating
temperatures.
Prolonged use under these conditions can cause condensation
build up within the compressor and may eventually lead to
emulsification of the oil.
Normal operating temperatures are reached in typically 10/15
minutes. To purge condensate from the compressor, a longer
running period with a high air demand is needed, usually a
minimum of 60 minutes will be required.
Conditions or applications which prevent the compressor
temperature stabilising between these parameters should be
avoided.
RS units have automatic stop/start cooling fans that cut in at 85°C
(185°F) operating temperature.
Consult your local Hydrovane Distributor if you have any
particular concerns about operational characteristics of your
compressor.
2.3 Operating Temperatures
Assuming the compressor is serviced correctly, the machine is
capable of operating in ambient temperatures up to a maximum
of 45°C (113°F) (40°C/104°F RS).
When the compressor is working, the temperature should be:-
Initial start-up and warm-up period. <70°C (158°F)
Optimum working temperature. 75-85°C (167-185°F)
High temperature. 90-100°C (194-212°F)
Some of the reasons for high compressor oil temperatures are:
a) Low oil level.
b) Blocked oil cooler or cooler flow restrictions.
c) Wrong type or grade of oil.
d) High ambient temperature.
e) Cooling fan stopped or operating incorrectly.
NOTE ! The controller display will show a warning when the
compressor temperature reaches 107°C (225°F).
NOTE ! The compressor will stop automatically if the
temperature rises above 110°C (230°F).
If the bulk oil temperature frequently reads 100°C (212°F) then
Fluid Force HPO oil should be used.
2.4 Noise Level
Although the sound pressure level for these units is relatively
low, they should be positioned where noise will not be a
problem.
