SECTION 1 - TECHNICAL DATA
1.1 - BACKGROUND INFORMATION
This machine has been manufactured from component parts and materials that conform to the new standards now in force. Each part of the Grimac
machine has therefore been carefully designed with particular attention being paid to the electrical system components and the elements that come into
direct contact with the coffee being dispensed.
1.2 - TAKING DELIVERY AND UNPACKING
The The TEN and TWENTY coffee machines are housed in a box that protects it from
being jolted and broken.
Open the box and remove the moveable cardboard protection in order to be able to take
hold of the bottom of the machine with both hands. Lift out slowly and carefully.
Rest the machine on a flat surface or table for the preliminary operations.
First, check that the machine is complete and undamaged.
Also check that underneath the coffee dispenser unit there is the box containing the
accessories that come supplied with the machine. (See figure alongside).
Before connecting the coffee machine to the mains electric power supply, check that the
mains voltage is compatible with the technical specifications.
THE ELECTRICAL SYSTEM MUST BE EARTHED.
ACCESSORIES SUPPLIED WITH THE MACHINE

39
1.3 - POSITIONING AND INSTALLATION
After checking that the machine is complete, locate it in the position in which it will be used. Ensure that the position is stable and safe and allows
enough space for carrying out the different operations (fitting the filter holder, obtaining hot water and steam).
The following appliances must be installed, adjusted and connected to the mains water and electric power supplies by qualified people in strict
compliance with the instructions contained in this manual.
To ensure that the machine works correctly and remains in proper working order, read this manual carefully, adhere to the standards which it sets out
and refer to the diagrams it contains.
Place the machine on a flat surface that is out of the reach of children.
To prevent the machine’s being knocked, do not locate it in places where there is a lot of movement to and from or in narrow corridors.
Connecting to mains power supply
Connect the power cable to the mains by means of a 24 amp fused switch as shown on the label on the cable.
.
Connecting to the mains water supply
1 - cold water must be supplied to the machine;
2 - check that mains water supply pressure is compatible with the technical specifications for the machine;
3 - connect the drain pipe to the tank underneath the drip tray and do not make tight bends;
4 - connect the 3/8" hose to the mains supply;
5 - ensure that there is an adequate inclination to enable water to drain away;
6 - if the mains supply water is to be treated with a water softener, follow the instructions set out on page 50.

40
1.4 - PRELIMINARY CHECKS
Check that: the electric plug has been inserted;
the drain pipe is connected to the mains water supply;
the drain pipe has been positioned in the manner specified in the instructions above.
