4. INSTALLATION PROCEDURE
When using the compressor lifting bracket and the
motor eyebolt as the slinging attachment points, it
is essential that a spreader of the correct length is
used. The lift should always be made vertically as
inclined loading severely reduces the safe working
load of the eyebolt. A 16 mm diameter shackle pin
is required for V1 00 and V150 units and a 19 mm
diameter shackle pin for V200, V300 and V400
units.
When the compressor is in position check that it is
clean and undamaged. Check that no blanking
covers and tapes are missing or damaged.
Make sure that the power supply to the compressor
is taken from an isolator incorporating suitable high
rupture current (HRC) fuses and that the switch is
locked 'OFF' and the fuses removed. Connect the
power supply to the compressor drive motor in
accordance with the diagram provided, using cables
which comply with the standards of the International
Electrotechnical Commission (I.E.C.).
The cables must be suitably protected and
clamped.
Connect the electrical wiring link between the safety
switch and the motor starter contactor in
accordance with the diagram.
If an airblast aftercooler is installed the electrical
wiring for the aftercooler fan motor should be
interlocked with the compressor motor starter or the
optional control panel, if fitted.
Following the guidelines above, make up the
necessary pipes to connect the air delivery flange of
the compressor to the air receiver or aftercooler but
leave the connection open. If appropriate, connect
the aftercooler and intercooler to the water cooling
system.
Make up and fit a connecting pipe between the air
governor and the receiver. This pipe should have a
minimum internal diameter of 6 mm unless the pipe
length is more than 7.5 m, when the minimum
internal diameter should be 9 mm. The pipe should
be blown through with compressed air before being
fitted.
On oil-free models fit the delivery valves in the
compressor cylinder heads as follows:
Remove the labelled gauze covers from the distance
pieces and take out the wrapped valves from the
cavity. Replace the gauze covers.
Remove the paper tape from all the gauze covers.
Remove the valve retaining covers from the cylinder
heads, withdraw the delivery valve retainers and
remove the desiccant bags. Fit the delivery valves
on the valve seats, ensuring that the copper joint
rings are in place and undamaged.
Refit the valve retainers and covers.
