CAUTION
Mains must be unplugged before unit is opened!
• Fan may start and there is a risk of injuries!
PLEASE NOTE
The flow control device and the by-pass valve are set according to specification and sealed. Any
modifications to these settings lie in the sole responsibility of the customer and must only be
carried out by expert staff.
The adjustment of the flow control device should not be made without the help of proper measuring
equipment, as the switching point must be set in a controlled way. Otherwise the function of the
safety circuit might not be reliable and, as a result, the device to be cooled might get damaged.
Flow control device
Before adjusting the flow control device, the fan's power must be disconnected!
The flow control device contains a closing contact whose OFF threshold is pre-set to a throughput of 4.0
litres per minute. For setting the switching point the switch head has to be adjusted. For that purpose the
screw retained by red locking varnish must be released and the switching head must be moved while the
throughput change is monitored by means of the equipment implemented for that purpose. After setting the
switching point the head fixing screw must be tightened firmly again.
By-pass valve
The by-pass valve is set by the manufacturer to a maximum pressure of 9 bars. If any modification to this
setting should be required, please contact the LAIRD THERMAL SYSTEMS service department to receive
briefing.
Before adjusting the flow control device, the fan's power must be disconnected!
