Water Connection

It is very important to install a "COLD" water supply line that is right under the unit or within 4 feet of the machine. A separate shut-off valve on the water line for the machine is strongly recommended for any emergencies, future preventive maintenance, or possible servicing.

The water line should also have a backflow preventer as determined by local building codes. Customers should seek the advice of a local licensed plumber as 1st-line is not aware of all local laws.

In addition, pressure reducer should be installed and set to maximum 40 pounds of water pressure - the reason is that on some espresso machines, the water pressure in excess of 45 pounds may open the internal valves and cause major water leakage.

On commercial espresso machines, the water connection always consists of a 3/8" diameter water line. It can be attached by using a 3/8" compression by 3/8 NPT (male thread) fitting. To ensure a leakproof thread, wrap teflon tape around the NPT threads. Stainless steel hoses supplied with each commercial espresso machine are British standard measure; Therefore, the fit between the hose and fitting (NPT side) will be very tight and may need slight cross-threading. Tighten the hose nut until the hose no longer swivels from the nut.

Drain Connection

It is important to locate the unit as close as possible to the drain, preferably a floor drain.

The drip tray usually drains into a black box (known as a catch basin), which in turn, drains into a vinyl tube. The vinyl tube from the black box must be kept as vertical (steep) as possible since there are always coffee grinds that will drain. In general, for every foot of hose that goes horizontal, the drain hose needs to drop one inch in the direction of the drain. If the vinyl tube is installed horizontally for more than one foot without the one inch drop, there is a greater potential for the vinyl hose to clog with grinds. This usually occurs when the vinyl hose is installed horizontally between the machine and the counter. Keep the vinyl drain hose from being pinched and connect it to the floor drain.

Electrical Connection

It is vital that proper power is readily available prior to installation. Please note that grinders require 110 volt receptacles to be located nearby with a connection to a circuit breaker independent of the espresso machine circuit breaker. For proper operation and un-interrupted operation, all commercial espresso machines should have dedicated circuits.

110 Volt Machines (15 amps or less) - Utilize standard 110-120 volt power supply with 110 volt plug and a twenty (15) amperage rating. Standard plug on cord is that found on many houldhold appliance. Three-prong plugs, including one for ground, is required.

110 Volt Machines (20 amps) - Utilize standard 125 volt power supply with 125 volt plug and a twenty (20) amperage rating. Standard plug on cord is NEMA configuration L5-20P. Three-prong plugs, including one for ground, is required. One of the three terminal on the plug is horizontal.

220 Volt Machines - Two grouphead units require single phase power that utilize a NEMA configuration L6-20 type plug and a twenty (20) amp dedicated circuit.. Three Grouphead units require single phase power that utilize a NEMA configuration L6-30 type plug and a thirty (30) amp dedicated circuit.
