4. INSTALLATION
4.1 ColdBRU Installation
Electrical Installation:
•Electrical specification: 15W-230VAC-50/60Hz
15W-120VAC-60Hz
•A moulded 13A IEC power cord is provided. This should be plugged into the IEC connection on the
rear of the ColdBRU and plugged into a suitable 13A power outlet.
•When installing the machine, always observe the local regulations and standards.
Plumbing Installation:
•Mains water pressure required (limits): 14.5 –145psi (0.1 -1 1 MPa)
•Fit a stop Valve on a cold water line and attach a 3/4" BSP male fitting, e.g. 3/4" x 1/2" or washing
machine type stop valve (3/8” compression US).
•Connect straight tailpiece of the hose to the stop valve fitting. Make sure that the pre-attached
sealing washer is fitted.
•Turn on the water to flush any impurities, dust etc. from the inlet hose and water pipe. Allow
several litres through.
•Connect 1/4” hose to the Bulkhead connector of the ColdBRU (1/4” pushfit). Make sure the 1/4”
hose is pushed in fully.
•Turn on water and check for leaks.

5. ColdBRU SETUP
5.1 Operating ColdBRU for the First Time
•Check that all installation procedures have been carried out.
•Ensure water valve is on.
•Plug ColdBRU into suitable socket.
5.2 Dispense Calibration Procedure (Required to be completed on initial startup)
The Dispense Calibration procedure should only be run if the machine has had major component
change, such as PCB or inlet solenoid that requires calibration settings to be re-done, or there has
been a change in the mains water pressure. Calibration option only remains on the screen for 5
seconds after power up. If you miss this window, power off the machine and try again.
Once the water weight has been input into the machine, a dispense operation can be performed
to check the accuracy of dispense.
