A post-mix soda system needs a steady supply of carbonated water. This unit pumps water into a pressurized stainless steel tank, where it takes up CO2 before heading out to the dispensing valves.
The Big Mac is the larger of the two McCann's carbonator series on the Multiplex specification sheet, with a 180 fl oz tank and two soda water outlets. The E400397-PP is the 115V model, now built with the potted probe switch that Multiplex announced in January 2025. Use it for a new fountain installation or as a replacement for an existing Big Mac.
Features
- 100 GPH rotary-vane brass pump with an internal 100 micron strainer and pressure relief valve. It delivers atomized water to the tank.
- Two-piece probe design. The electronics package comes off for testing and service without shutting off CO2 or water and without depressurizing the tank.
- Fully potted probe switch. Potting waterproofs the electronics inside the probe, which Multiplex names as the most frequently replaced part on the carbonator.
- Diamond Brite stainless steel construction that resists corrosion and is easy to clean.
- Injection molded base on vibration-isolating rubber feet for sound insulation.
- Anderson Brass backflow prevention device specified to ASSE 1022, plus a 180 PSI pressure relief valve.

Compatibility
Multiplex states that the potted "-PP" parts are backwards compatible and can be installed on previous generation carbonators. This is the 115V, 60 Hz model. The 220V Big Mac is a different model with a 1/4 HP motor and a stainless steel base. The manufacturer also lists a Pump Saver, which shuts the unit down at low water pressure, and a wall-mounted shelf as options. Neither is confirmed as included with this carbonator.

Frequently asked questions
What power supply does this carbonator need?
It runs on 115V, 60 Hz, single phase. The motor is 1/3 HP, draws 6.5 amps and turns at 1725 RPM.
What fittings do I need to connect it?
The CO2 inlet is 1/4 in. male flare. The water inlet and both soda water outlets are 3/8 in. male flare.
Does it come with a backflow preventer?
Yes. The specification sheet lists an Anderson Brass backflow prevention device, specified to ASSE 1022, as a standard feature.
Can the potted probe version replace an older Big Mac?
Multiplex's January 2025 service bulletin says the new "-PP" parts are backwards compatible and can be installed on previous generation carbonators. The bulletin lists the E400397-PP as the potted version of the 115 V, two-outlet Big Mac.
Do I have to shut off CO2 and water to service the probe?
No. The two-piece probe design lets the electronics package be removed for testing and service with no need to shut off CO2 or water or to depressurize the tank.
