Start Up (Commisioning) - Hertz HGS 3-20 Bedienungshandbuch

4.4 START-UP
Before start up the compressor, check the electrical and air line connections.
Check that the compressor's cooling air inlets and outlets are not closed. Do not cover your compressor
with cloth, nylon etc. Do not operate if covered.
Inside electrical panel of your compressor there is a "phase control relay" that continuously checks the
phases. In case the phases are connected in reversed or if there is unbalance or interruption in your
voltage, the phase control relay will prevent operation of the compressor. In this case, a signal behind
the phase control relay that indicates the phase error warns you. When the phases are connected
reverse, switch off the energy and switch the position of main cables of the compressor. In case of
interruption or phase unbalance, as this problem is related with the network contact an electrician or
related institution.
When the energy and air lines of your compressor are completed, inform your service for
commissioning. Our service will perform the general inspections, start up the compressor and supply
you beneficial information related to your compressor and its maintenance. If you want to start up the
compressor by yourself read this handbook very carefully. Performing an erroneous process may be
hazardous for your compressor facility or the personnel working in this region.
Check the oil level. On the oil receiver body there is a transparent
hose for easily seeing the oil level (on the belt driving models). Check
the oil level when compressor is at the stop position. During operation
the oil level may vary.
If the oil level is missing, complete it. Information related to oil is
described in section 5 (MAINTENANCE), part "COMPRESSOR OIL".
Oil level should not be below the mid-point of the hose
Check the internal components and connections of the compressor.
Make sure that during transportation it has not been damaged.
Oil filling tap is on the compressor unit for the direct drive models.
While compressor is not working you can check the oil level.
Oil level should reach beneath the pitch of the tap
Apply energy to compressor and see if the light is 'on' above phase
control relay in the electric board. If it is 'on' electric connection is
regular. If it is 'off' phase row is wrong
