Do not open the starter compartment or touch
electrical components while voltage is applied
unless it is necessary for measurements, tests or
adjustments. Such work should be carried out only
by a qualified electrician equipped with the proper
tools and wearing appropriate body protection
against electrical hazards.
On a unit equipped with an Automatic Start/Stop
system, attach a sign stating ‘THIS UNIT MAY
START WITHOUT WARNING’ next to the display
panel.
On a unit equipped with an Automatic Restart
device, attach a warning notice stating ‘THIS UNIT
HAS BEEN MODIFIED AND WILL START
AUTOMATICALLY ON APPLICATION OF
POWER’ next to the display panel and on the
inside of the unit next to the starter contactors.
If the unit is equipped with a Remote Control
device, attach warning notices stating ‘THIS UNIT
CAN BE STARTED REMOTELY’ in prominent
locations, one on the outside of the unit, the other
inside the control compartment.
As a further safeguard, take adequate precautions
to make sure there is no one checking or working
on the unit before attempting to switch on remotely
controlled equipment. Attach a ‘CHECK THAT
ALL PERSONNEL ARE CLEAR OF THE UNIT
BEFORE STARTING’ or similar warning notice to
the remote start equipment.
During normal operation no internal part of the
compressor unit should reach a temperature above
120°C and protection devices are fitted to prevent
excessive temperatures occurring. If there is any
indication that the compressor is overheating it
must be shut down and the cause investigated.
Beware of burns from hot metal parts, hot oil and
water when working on a unit which has recently
been shut down.
The compressor must not be operated at
pressures above the nominal pressure given on
the data plate.
The compressor must not be operated in ambient
temperatures outside of those given under
‘Leading Particulars’.
The ‘Noise at Work Regulations 1989’ suggest that
ear protectors should be worn where noise levels
are 85 dB(A) or higher. With all covers in place,
the noise levels of the compressors described in
the manual are substantially lower than this figure
unless installed in an already noisy environment.
Be aware that high noise levels can interfere with
communication.
6. MAINTENANCE AND REPAIR
PRECAUTIONS
Maintenance, repairs or modifications must only be
carried out by competent personnel under a
qualified supervisor.

BroomWade Genuine Parts.
Before removing any panels from the enclosure, if
fitted, or dismantling any part of the unit, carry out
the following preparatory operations:-
1. Isolate the compressor unit from the main
electrical power supply. Lock the isolator in
the ‘OFF’ position and remove the fuses.
2. Attach a label to the isolator switch and
display panel carrying the warning ‘WORK IN
PROGRESS – DO NOT APPLY VOLTAGE’
Do not switch on electrical power or attempt
to start the unit if a warning label is attached.
3. Close the isolating valve between the
compressor unit and the user’s pipework.
Close the isolating valve in the cooling water
inlet pipe. Attach a label to each valve
carrying the warning ‘WORK IN PROGRESS
– DO NOT OPEN’
4. Ensure that the blowdown system has
operated to release all pressure from the oil
separator vessel.
5. Check that the pressure gauge registers zero.
