Chiller filling procedure
Remove the cap from the tank lid on the top of the chiller.
Fill the tank to leave 10-20mm (0.4-0.8”) of air between water line and where the lid seals. It is
recommended that the chiller is used with deionised water.
Turn your attention to the power inlet rocker switch on the back of the chiller.
Immediately after toggling this switch the chiller will begin to pump water.
Turn on the MFFT instrument and set the operating range to 1.
Leave the chiller running until the water line drops to just above the lower outlet port, then turn
it off, this may take a few minutes as the valve inside the MFFT needs to open. Once the
valve opens the water can flow freely through the system.
When the water level drops turn off the chiller. Refill the tank back to original level, repeat until
the level no longer drops when the pump is run.
Start the chiller by once again toggling the mains inlet rocker switch on the back of the
chiller.
Leave the cap off the tank for >30mins to allow air to escape, or very loosely screwed on to
prevent water splashing out of the tank.
Check the application and tubing for signs of leaks whilst the chiller is running.
Replace the tank lid fully when satisfied the system is full and bled of air.
Adjusting the temperature set-point
Press the key P then release it and the display will show “SP”
alternating with the set value. To change it press the UP key to increase the value or DOWN
to decrease it. The set point for use with the Rhopoint MFFT should be +10deg C.
The speed dial controls the duty of the compressor within the chiller. This directly translates to
how hard the chiller works at cooling. For operation with the MFFT set the dial to 8.
