Ref. Description/recommendation
5 The drain pipes to the drain collector must not dip into
the water of the drain collector. Atlas Copco has oil/
water separators (type OSD) to separate the major part
of the oil from the condensate to ensure that the
condensate meets the requirements of the
environmental codes.
6 Control module with monitoring panel.
7 Mains cables entry.
8 Filter type DD (optional) for general purpose filtration
(particle removal down to 1 micron with a maximum
oil carry-over of 0.5 ppm). A high-efficiency filter,
type PD (optional) may be installed downstream the
DD filter (particle removal down to 0.01 micron with
max. oil carry-over of 0.01 ppm). If oil vapour and
odours are undesirable, a filter of the QD type (optional)
should be installed downstream of the PD filter.
It is recommended to install by-pass pipes over each
filter together with ball valves, in order to isolate the
filters during service operations, without disturbing the
compressed air delivery.
9 By-pass system to by-pass the dryer during service
operations (available as an option, consult Atlas
Copco).
10 High efficiency water separator, removes 90% of the
moisture in the compressed air when by-passing the
dryer.
Attention:
Working with machinery controlled by a frequency converter
requires special safety precautions. These safety precautions
depend on the kind of network used (TN, TT or IT system).
Consult Atlas Copco.
2.4 Electrical connections (Fig. 1.11)
- Check the fuses and the setting of the circuit breaker. See
section 7.3.
- Connect the power supply to line contactor (K21). Connect
the earth conductor to connector (PE). Consult section
2.2.
3 OPERATING INSTRUCTIONS
Safety precautions
The operator must apply all relevant safety precautions,
including those mentioned in this book.
Altitude operation
Consult Atlas Copco if operating above 1000 m.
Moving/lifting
The compressor can be moved by a lift truck using the slots in
the frame. Take care not to damage the bodywork during lifting
or transport. Before lifting, reinstall the transport securing
bolts (see section 3.1). Make sure that the forks protrude from
the other side of the frame. The compressor can also be lifted
after inserting beams in the slots. Make sure that the beams
cannot slide and that they protrude from the frame equally.
The chains must be held parallel to the bodywork by chain
spreaders in order not to damage the compressor. The lifting
equipment must be placed in such a way that the compressor
will be lifted perpendicularly. Lift smoothly and avoid
twisting.
3.1 Initial start-up
Remarks
1. Read the "User manual for Elektronikon regulator" to
familiarize yourself with all regulator functions.
2. Consult section 2 for the dimension drawings, electric cable
size and installation proposal.
Start-up
1. The compressor element and motor are secured to the
frame, immobilizing the vibration dampers during
transport.
Remove the bolts and bushes (4-Fig. 3.2) immobilizing
the vibration dampers of the compressor element.
Remove bolts (2-Fig. 3.2) and support (3-Fig. 3.2).
2. Check that the electrical connections correspond to the
local codes and that all wires are clamped tight to their
terminals. The installation must be earthed and protected
against short circuits by fuses of the inert type in all phases.
3. Check the voltage selecting wires at the primary side of
transformers (T1 and T2-Fig. 1.10) and the setting of fan
motor circuit breaker (Q15-Fig. 1.10). Check that the
switch on the circuit breaker is in position "I".
4. Fit the air outlet valve to the air outlet pipe. Close the
valve. Connect the air net to the valve.
5. Connect the manual and automatic condensate drain outlets
to a drain collector as described in section 2.3.
