6. Preparations for commissioning

Perform first-time water filling as follows:
•
Connect the customer's water supply.
•
Open manual valve – water in (-1- Fig. 16).
Water flows through the inlet (-3- Fig. 16) into the
pressure tank (-7- Fig. 16).
• Fill up to the fill level marking "Above" (-5- Fig. 16).
•
Close manual valve – water in (-1- Fig. 16). Start
system and monitor the water level.
•
Once the fill level marking "Below" (-4- Fig. 16) has
been reached, turn off system via the emergency
off.
•
Open manual valve – water in (-1- Fig. 16).
•
Fill with water up to the fill level marking "Above"
(-5- Fig. 16).
•
Close manual valve – water in. Start system and
monitor the water level.
•
Once the fill level marking "Below" (-4- Fig. 16) has
been reached, turn off system via the emergency
off.
Repeat this filling process until the water level has
balanced out between the fill level markings.
If water is required during operation (water changing/
levelling), the drinking water supplied is treated by
means of the internal RO unit.
By mixing circulation water, drinking water and treated
water, the requisite level of water quality will be
achieved over the course of time.
6.6 Extraction of water samples
Danger
Water samples must only be extracted when the
rotary screw compressor unit is stationary and
depressurised.
Switch off the compressor and ensure that it is
depressurised.
•
Open the ball valve at the extraction site (-2- Fig. 21)
and to flush the extraction site, allow around 0.1 l to
drain into an appropriate vessel.
•
Fill the vessel provided (water analysis set) with the
sample quantity (approx. 0.3 l).
•
After extracting the sample, close the ball valve.
•
Check the water level on the water level indicator
(-6- Fig. 16) and add water if necessary (see
Chapter 6.5 Water supply).
6.7 Sound pressure level
Sound pressure level measured in dB(A) according to
PN8NTC 2.2 under a 70% load at a distance of 1 m
(tolerance: ± 3 dB(A)):
water-cooled D110H RS-W 72 dB(A)
water-cooled D75H RS-W 77 dB(A)
air-cooled D75H RS-A (50 Hz) 76 dB(A)
air-cooled D75H RS-A (60 Hz) 78 dB(A)
water-cooled D50H RS-W 75 dB(A)
air-cooled D50H RS-A (50 Hz) 75 dB(A)
air-cooled D50H RS-A (60 Hz) 77 dB(A)
Subject to technical revision.
