8. Start-up
Please note Security advice (see also chapter 1.3)
At storage temperature < 10°C allow for an appropriate
acclimatization period before turning the cooler on ( formation of
condensation water!).
The cooler is designed for the exclusive cooling of water.
Fill water circuits with water according to specifications only .
8.1 Start-up
Disconnect mains voltage and remote control by Harting plug
Put protective motor switch in the respective – 0 –positions,
Remove covering panels and tank covers,
Fill tanks with water up to the MAX marking provided at the level indicators,
Vent pumps via vent screw provided at pump housing,
Connect mains voltage by Harting plug,
Turn on remote control from machine at customer side (please refer to
machine operators manual),
Put automatic fuse and protective motor switch for pumps and fans
in the respective – 1– position (see also circuit diagram),
Switching on pumps remote control from the machine,
Check direction of rotation of pumps.
In case of incorrect direction of rotation of pumps, render cooler
electrically dead and reverse the 2 (two) phases of the main
connection cable. Dry-run of pump to be avoided, therefore filling up
first before starting pump. In case of closed system type, the
additional venting system provided at the customer’s site must be
actuated
When starting up pump(s) or consumer, the water level in the tank falls
down. Check water filling level at the level indicator. Refill water if required.
Check the water circuit visually as to tightness,
Check required water volume flow by means of the pressure gauge and
the pump performance chart (see also appendix - Pump Characteristic
Line)
Mount tank covers and covering panels,
Put protective motor switch for compressors in the respective – 1–
position,
Acknowledge all fault and warning messages at the control unit,
Check rated value setting of the thermostatic controller.
The cooler is ready to work, the thermostatic controller take over the
control of all water circuits temperature.
