1.2 SAFETY PRECAUTIONS
GENERAL SAFETY RULES
Do not leave packing materials (plastic bags, expanded polystyrene, nails, cardboard, etc.) within the
reach of children, as these items are a potential source of danger.
Verify that the electrical data of the machine corresponds with the electrical supply network before
connecting the machine to the power source. PLEASE NOTE: Egro Model 55 series machines require 208V
30amp main power supply. If you are located in a area which experiences fluctuations in power which cause
the main power supply to drop below 208V, it is highly recommended that you install a power booster in line
with the Egro 55 series equipment.
Electrical adaptors, multiple sockets, and or extensions should not be used.
Request a detailed description of the available power from an electrician. The electrical outlet must have
the following safety features:
- Dedicated ground
- Wiring suitable for wattage capacity
- Circuit breaker
Install the machine on a water repellent surface (laminate, steel, ceramic etc.). Keep the machine away
from heat sources (oven, stove, fireplace, etc.) and away from extreme cold, the temperature should not
fall below 41oF.
Do not leave the machine exposed to harmful environmental elements, such as rain, snow, or humidity.
Do not obstruct the drain on the drip tray. Be sure drain tray is clean and waste can easily flow into the
drain tube.
Store the packed machine in a dry warm place. Do not store where the temperature may fall below 41oF.
Do not stack heavy items on the packaging.
In case of emergency, such as the machine catching on fire, unusual noises coming from the machine,
overheating etc, maintain your personal and the safety of those around you FIRST. When it’s safe,
immediately disconnect the power and close all water taps.
Use only authorized spare parts in order to avoid compromising the safety and proper functioning of the
machine.
Equipment installed incorrectly can cause damage to people and items for which the manufacturer cannot
be responsible.
