The width of the grounding wire must be min. 16mm² (AWG 6) or of the same width of the power supply.
The grounding must be an isolated ground and must connected on the ground terminal (X1) in the switch
cabinet. The ground resistance must be less than 10 Ohm.
Metal cable conduits are not allowed for grounding.
The piping of the chiller (supply and return) have to be grounded too.
Do not share the ground wire with other devices.
Always use a ground wire that complies with technical standards on electrical equipment and minimize the
length of the ground wire.
When using more than one Inverter, be careful not to loop the ground wire.
(e.g. a CT-Chiller KPC108-L-U/S stands near an Avanto-Chiller KSC215-L-U/S)

Filling the unit with water-ethylene glycol-mixture
Water to be used (de-ionized water / destilled water / VE water / bartly de-ionized water)
This type of water has to be purchased and provided locally
Mix it with Ethylene-glycol at the rate of min. 35% to max. 38%.
Use ethylene-glycol of only one manufacturer.
(e.g.: DOWTHERM SR1-Dow Chemical, Safeflow EG-Clariant)
Do not mix two ore more different manufacturer for one water-ethylene-glycol circuit.
Open front panel and fill to a pressure of min.1,5 bar via the feed cock when the pump is off.
After filling, check all connections for leakage.
Don’t use propylene-glycol or automotive antifreeze

3.4
Draining air from the unit
The KSC 215 includes a closed water system.
If air get out of the system the water pressure drops down. If that happens you had to check the water
pressure and if its to low you have to refill the water circuit.
The procedure should be repeated until no more air is in the system
After all these steps, turn the main switch in position "1". If all the prerequisites for operation have been met,
the chiller will start at the latest 1 minute.
In case of malfunctions: search for faults, take note of Chapter 9, TROUBLE SHOOTING, in this manual.
