1.Obtain wakeup time, sleep time, defrost times, and viscosity settings from current setup.
2.Disconnect power (unit may have to be pulled from wall to access electrical outlet).
3.Shut off syrup supply by shutting down CO2. Bleed CO2 from inlets to BIB pumps.
4.Remove left side, front access and rear panel.
5.Remove No. 1 cylinder syrup inlet line and No. 1 syrup flow sensor assembly (leftmost if facing unit).
6.Install new syrup inlet line (2 flavor OC unit), or connect existing line with tubing elbow and cable tie (2 and 4 flavor standing units) to pressure switch assembly (see Figure 1). Assemble locks onto pressure switch assembly and reconnect electrical harness paying close attention to maintaining wiring integrity. Switch is supplied with adapter harness to retrofit existing wiring (wires to be attached to “C” common and “NC” nor- mally closed. Note: some parts will be left over.
7.Repeat steps 5 and 6 for No. 2, 3 and 4 syrup inlet lines and syrup flow sensor assemblies.
8.Remove existing main control board EPROM chip using an EPROM extraction tool. Install EPROM taking great care not to misalign pins or cause damage to chip. Note: wearing ground strap is stronly recom- mended to protect board from electrostatic discharge. Take care to put each connector back in its proper location.
9.Remove existing No. 1 cylinder product delivery board. Install new product delivery board (using ground strap). Take care to put each connector back in its proper location.
10. Repeat step 9 for product delivery boards No. 2, 3 and 4.
