Installation
Contents
When unpacking the machine, the following items should be included:
* 4 NSF Legs (6 for a 4 group machine)
* Pump & motor assembly
* Portafilters
* Drain Hose
* Tamper
* PuroCaff Cleaner
* Owners manual
* Inlet hoses, 24”, 48”, and 84” lengths
* Warranty card with water test strip attached
Water Requirements
A dedicated water line with its own shut-off valve should be placed within four feet of machine instal-
lation location. The shut-off valve should be equipped with a male 3/8 compression fitting.
The machine operates best with water between 0-3 grains of hardness. Higher hardness levels may
cause damage due to scale forming inside the machine. If the supply water has a hardness above
3 grains per gallon install the appropriate water softener.
ENSURE ALL SOFTENING/FILTERING
CARTRIDGES HAVE BEEN ADEQUATELY FLUSHED BEFORE CONNECTING TO THE MA-
CHINE.
ESI recommends our H
2
O for Espresso system. This cartridge provides both a carbon block to filter
out tastes and odors as well as ion exchange resin for softening of the incoming water. The car-
tridge also incorporates a 20% bypass to neutralize the pH allowing for a water “recipe” that pro-
vides the best tasting espresso.
In some areas of the country, the use of a Reverse Osmosis system, is necessary. When us-
ing an RO system, ensure a small percentage of raw water bypasses the RO system and is then
reintroduced into the RO water fed to the espresso machine. This helps prevent corrosion due to
aggressive water properties. The “postmix” water should then be fed through a carbon block filter to
remove tastes and odors.
Power Requirements
The following voltages and amperage ratings apply.
* 1AV OR EE – 208 - 240v, 20amp
* 2AV OR EE– 208 - 240v, 30amp
* 3AV OR EE– 208 - 240v, 50amp
* 4AV OR EE– 208 - 240v, 50amp
There are two electrical cords attached to the machine.
The smaller diameter cord supplies pow-
er to the pump motor assembly and should be connected to the pump motor, NOT plugged
into a wall outlet.
Drainage Requirements
Ensure the drain hose provided with the machine runs downhill to an appropriate floor drain.
