Installation
•The chiller must be installed so that the suction and discharge of air can take
place properly. Keep free space surrounding the chiller at least 10 cm
•Connect the ingoing water pipe …………………………………………………………………… Nr. 6 page 5
•Connect the outgoing water pipe ……………………..……………………………………………. Nr. 8 page 5
•Fill up the water tank with fresh water ( ±125 l ) ……………………………………………. Nr. 7 page 5
•Plug the chiller in a earth connected wall connection ………………………………………… Nr. 9 page 5
•Switch the chiller on by turning the thermostat knob clockwise
The electrical installation must be saved with a 16amp. fuse
Maintenance
•The water in the water tank must be refreshed once a year minimum
•Check the water level in the water tank on a regular basis and fill up if necessary
•The condenser must be cleaned regularly with a soft brush to remove dust for a proper airflow

Temperature display
Display
At the power up the unit shows “---” during 3 seconds approximately during which it performs a self check, then the current value
according to the configuration set appears. If the SIM is different from 0 it’s possible to display the instantaneous value by pressing
+ . The unit permanently stores the minimum and maximum values measured during the normal operation. The stored values are
displayed by respectively pressing button or and cleared by pressing button for 1 second.
If the readout exceeds the limits then “OR” is displayed, while in case of probe failure “PF” appears.
Configuration (setup)
Access to the configuration of the unit takes place through the following sequence: switch of the unit (unplug the power cord of the chiller),
keep buttons + pressed then switch on unit again. Scroll through the parameter list with or until you get the desired one, then
get its value displayed with and change it with + or + . Exit from the setup takes place by letting the keypad untouched for
10 seconds.
