7 Preparations for commissioning

7.5
Demineralisation unit
The following points are to be considered when using
the demineralisation unit:
1) To be used only for the first filling of the compressor.
2) The quantity of water is reduced to approx.
0.26USgal/minute due to the integrated flow limiter.
3) Complete filling can take up to 90 minutes.
4) The cartridge is designed for a maximum water
quantity of 11.9 USgal.
5) After initial filling the water supply to the compressor
should be taken directly from the mains.

Undertake the initial filling with the
demineralisation unit as follows:
•
Apply water connections for the inflow (-A - Fig. 13)
and the connection between the outflow (-B- Fig. 13)
with the water inflow from the compressor (-C- Fig. 14)
•
Open stopcock for filling process (-2- Fig. 13). If
necessary open the vent on the filter head of the
demineralisation unit. The water level in the filter rises.
•
Open manually operated valve – water on (-1- Fig. 12).
The water flows via the inflow (-C- Fig. 14) into the
pressure reservoir (-7- Fig. 12).
•
Fill water up to the fill level marking "Above" (-5- Fig.
12). This process may take up to 90 minutes.
•
Close manually operated valve – water on (-1- Fig. 12);
start the system and observe the water level.
•
When the fill level marking "Below" (-4- Fig. 12) is
reached, switch system off via the emergency stop.
•
Open manually operated valve – water on (-1- Fig. 12).
•
Fill water up to the fill level marking "Above"
(-5- Fig. 12) again.
•
Close manually operated valve – water on. Start
system and observe water level.
•
When the fill level marking "Below" (-4- Fig. 12) is
reached, switch system off via the emergency stop.
•
Continue this filling procedure until the water level
has balanced out between the fill level markings.
•
After filling, remove the connection between outflow
(-B- Fig. 13) and the water inflow (-C- Fig. 14) on the
compressor.
•
Connect water supply directly to the mains.
7.6
Extraction of water samples
WARNING
Air/water under pressure may cause severe
personal injury.
•
Shut down compressor, relieve system
of all pressure, disconnect, lockout and
tagout power supply to the compressor
package before extracting water
samples.
•
Open the ball valve at the extraction site (-2- Fig. 17)
and to flush the extraction site, allow around
0.026 USgal to drain into an appropriate reservoir.
•
Fill the reservoir provided (water analysis set) with
the sample quantity (approx. 0.08 USgal).
•
After extracting the sample, close the ball valve.
•
Check the water level on the water level indicator
(-6- Fig. 12) and add water if necessary (see
Chapter 7.4 Water supply).
