INSTALLATION

Cold BRU 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 Cold BRU 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 Cold BRU (1/4” push fit). Make sure the 1/4” hose is pushed in fully.
• Turn on water and check for leaks.
• Check that all installation procedures have been carried out.
• Ensure water valve is on.
• Plug Cold BRU into suitable socket.

ColdBRU SETUP

Operating ColdBRU for the First Time

• Check that all installation procedures have been carried out.
• Ensure water valve is on.
• Plug Cold BRU into suitable socket.

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.

OVERVIEW & OPERATION

ColdBRU – Operation

When performing this operation, use the 7.67L container to catch dispensed water. This can then be weighed to confirm the machine is within spec

ROUTINE MAINTAINENCE/INTERNAL ACCESS

Maintenance should be carried out by Marco approved technicians only. Before undertaking routine maintenance on Cold BRU disconnect machine from mains power and water supply.

Top Lid removal:

1. Remove the screws in the top lid with a suitable screwdriver.
2. Lift lid upwards and remove.
   

PCB removal (1600501 / 1600502(US)):

1. Disconnect machine from mains power.

2. Remove Top Lid as per section 7.1

3. Disconnect all wiring connected to the PCB.

4. Remove two countersink screws and the two screws attaching the PCB bracket inside the head of the machine with a suitable screwdriver shown in the picture below.
   

5. Remove the two nuts attaching the Sprayhood bracket to the Head assembly. This will allow you to move the components attached to the Sprayhood bracket and give enough room to remove the PCB bracket. Remove the PCB bracket with the PCB still attached.
   

6. Remove 4 screws to release PCB from PCB bracket.
   

Inlet solenoid removal (230V – 1502196 / 120V – 1502198)

1. Disconnect machine from mains power.

2. Disconnect all wiring connected to the PCB.

3. Close water supply valve at the source and remove 1/4” hose from the bulkhead connector at the back of the machine. Note: Water already in the machine and 1/4” hose coming from the mains water supply will drain upon removal.

4. Remove Top lid side panel as per section 8.1
   

5. Disconnect all wires and hoses to the inlet solenoid. Remove the Spray head bracket from the head assembly by removing the two m6 nuts as shown below.
   

6. Once the Spray head bracket and all attached parts have been removed from the head assembly you will have access to the two solenoid retaining screws. Remove these to detach the inlet solenoid. Note: orientation of solenoid mounting bracket.
   

Spray head and Spray head disc removal

1. Disconnect machine from mains power.

2. Close water supply valve at the source and remove 1/4” hose from the bulkhead connector at the back of the machine. Note: Water already in the machine and 1/4” hose coming from the mains water supply will drain upon removal.

3.  If only replacing the Sprayhead disk, you can access and remove the m6 x 50mm screw from the
   underside of the Welded head assembly as shown below. Note: If removal of the entire
   Spray head is required, skip this step and continue to step 4.
   

4. Remove Top lid side panel as per section 8.1

5. Disconnect all wires from the PCB.

6. Disconnect the Valve Elbow adaptor and remove the two nuts that hold the Spray head bracket in place. Lift the Spray head bracket with all attached parts out of the machine.

7. Remove the Spray head from the Spray head bracket by unscrewing the m6 nut shown below.
   Using an appropriately sized wrench, remove the elbow from the Spray head
   

Flow meter replacement (2301183)

1. Disconnect machine from mains power.

2. Disconnect all wiring connected to the PCB.

3. Close water supply valve at the source and remove 1/4” hose from the bulkhead connector at the back of the machine. Note: Water already in the machine and 1/4” hose coming from the mains water supply will drain upon removal.

4. Remove Top lid side panel as per section 8.1

5. Disconnect the Valve Elbow adaptor and remove the two nuts that hold the Spray head bracket in place. Lift the Spray head bracket with all attached parts out of the machine.
   

6. Remove tubing connected to the Flow meter.

7. Cut cable ties to release Flow meter from the Spray head bracket.
   

DIAGNOSTICS

TROUBLESHOOTING – DIAGNOSTIC GUIDE:

| Reported Issue| Component| Check
---|---|---|---
1.| Not dispensing water|

Valve Inlet Solenoid 1/4″ push fit (230V – 1502196 / 120V – 1502198)

|

• Check power supply from PCB/230V ok.
• Choose a brew in the MENU. While the brew is operating, check the Power to the solenoid is within range, 220-240v AC. If there is no Power, change the PCB.
• If there is power and the solenoid fails to operate, replace the Solenoid valve

2.| Inaccurate water volumes|

Digi mesa Flow Meter (2301183)

|

• Recalibrate the machine as per section 5 “Cold BRU Setup”.
• If issue persists check power supply from PCB/230V ok.
• If 230V from PCB replace Flow Meter.

3.| Not dispensing water|

PCB Control Mix 230V / PCB Control Mix 110V (1600501 / 1600502)

|

• Check power supply from 230V ok.
• Select a brew and begin brew program. Check power between PCB and components/
• If components not receiving power, replace PCB
