Espresso Machine Installation Guide
The following information is an overall guide or reference for people to use who are unfamiliar with installing a commercial espresso machine and grinder for their coffee shop.
Commercial Espresso Machine
The best work bench to set your machine on is one that is well ventilated and dry, and ideally it should be between 32″-45″ high. For the same of making maintenance and cleanup easier, you should try to have at least 6″ of free space on all sides of the machine.
Keep in mind also, that you may need some extra space for your grinder which, for most right-handed baristas, will be found on the right hand side of your commercial espresso machine.
You are also going to want a space of around 17x17x12 underneath of your machine in case you need space for your filter, external motor, or external pump if your machine includes any or all of these.
Connecting any of these to your machine will require you to drill a hole in your work bench, aiming for around the middle of where your machine will be, ideally about 3″ in size.
Most commercial espresso machines are hooked up directly to your plumbing, and it is always best to have a licensed plumber set this up for you. Also don’t forget that if your water is not kept at 2-3 GPG, your manufacturer will most likely have the right to void your warranty, so it’s best to discuss this with your plumber as well.
Normally espresso machines will come with an inlet hose that has a 3/8″ female fitting that will connect to your filter directly.
Always engage a licensed electrician to sort everything out for you as your power needs can become quite complicated. For instance most commercial machines will require a 220-240 volt power supply (single-phase), and your specific machine will also have a recommended current protection range which should be adhered to.
As for the logistics of the power, most coffee shops will keep the supply directly underneath of the machine and run the cord up through the hole drilled in the bench. Keep in mind that most commercial espresso machines have a 40″ lead coming from the back side on the left.
Make sure you install weather proof power switches if you live in an area where water or moisture can become an issue.
The vast majority of commercial machines will require a 15A-30A power supply, though machines with 3-4 heads (multi-boiler machines) may require you to have a 40 amp outlet installed.
Home machines will generally speaking only require a 10A / 110 volt outlet. And in case all this is still not enough to convince you to call a real electrician, also remember that it is not at all unusual for commercial espresso machines not to include a plug, so your electrician will also be responsible for finding and installing the right plug for your machine and your power setup.
Drainage and Waste
You will want to have direct drainage rather than having to dump out your espresso waste manually (especially if your shop has a high output), so you’ll need a drain-pipe with a trap.
The overwhelming majority of the time (probably 99%), commercial espresso machines will include a 30″-40″ drain hose.
