1.INTRODUCTION:
The information provided in this manual is intended to assist in the installation and maintenance of
the Marco SP9 System, consisting SP9 Boiler and either one or two SP9 Head Units (Single/Twin).
Please read the instructions carefully to prevent accidents and ensure an efficient installation.
This manual is not a substitute for any safety instructions or technical data affixed to the machine
or its packaging. All information in this manual is current at the time of publication and is subject to
change without notice.
Only technicians or service providers authorised by Marco Beverage Systems should carry
out installation and maintenance of these machines.
Marco accepts no responsibility for any damage or injury caused by incorrect or unreasonable
installation or operation.
2.SAFETY INSTRUCTIONS:
When using electrical appliances, basic safety precautions should always be followed to prevent
the risk of fire, electric shock, burns or other injuries or damages.
• Read all operating and safety instructions carefully.
• This machine must be earthed. If the moulded plug supplied is not used then ensure that the
green/yellow cable is connected to a suitable earth.
• Risk of flooding: The hose supplied with the boiler is non-toxic food quality tested to 190psi.
However, a hose is not a permanent connection. It is, therefore, advisable to switch off boiler and
close the stopcock valve when boiler is not in use. e.g. overnight, etc.
• The utmost care has been taken in the manufacture and testing of this machine.
• Failure to install, maintain and / or operate this machine according to the manufacturer’s
instructions may result in conditions that can cause injury or damage to property. If in any doubt
about the serviceability of the machine always contact the manufacturer or your own supplier for
advice.
• This machine is not intended for use by persons (including children) with reduced physical,
sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given
supervision or instruction concerning use of the appliance by a person responsible for their safety.

• Children should be supervised to ensure that they do not play with the machine.
• In the event any wires are damaged, such wires can only be replaced by experts or professional
service staff from the manufacturer service department or similar functional departments.

4.INSTALLATION:
Electrical Installation:
Electrical specification: 2.4kW-230VAC-50/60Hz
A moulded 13A IEC power cord is provided. This should be plugged into the IEC connection
on the base of the boiler and plugged into a suitable 13A power outlet.
When installing the machine, always observe the local regulations and standards.
Plumbing Installation:
Mains water pressure required (limits): 5-50psi (35-345kPa) 0.5 –5.0 bar
Fit a stop Valve on a cold water line and attach a 3/4" BSP male fitting, (e.g. 3/4" x 1/2" 311
or washing machine type stop valve).
For US versions use 3/8” NPT male fitting.
Connect straight tailpiece of the hose to the stop valve fitting. Make sure that the pre-
attached sealing washer is fitted.
Turn on the water to flush any impurities, dust etc. from the inlet hose and water pipe. Allow
several litres through.
Connect right-angled tailpiece of the hose to the inlet valve of the boiler (3/4" BSP). Make
sure the sealing washer is fitted here also.
Turn on water and check for leaks.
Installation of SP9 Head Unit:
A full A4 sheet sized version of the counter cut-out template,
seen opposite in Figure 1, can be found on the last page of
this manual.
The cut-out is simply two 80mm holes centred 83mm apart.
Alternatively, the area outlined in red, bounded by the two
circles and the parallel lines (obround shape) can be cut out
using a jig-saw or similar.
Once the cut-out is complete, mount the SP9 Head Unit using
the brackets supplied. See Figure 3, below. Use the
appropriate rubber spacers on the brackets to match the
thickness of the counter.
Attach the electrical connector and the two hoses to the
appropriate ports on the under counter unit.
A goes to A, B goes to B and DIN goes to DIN.
For a Single Head System, use A1, B1 and DIN1.
For a Twin Head System, connect Head Unit 1 as in a Single
Head System. Connect Head Unit 2 to A2, B2 and DIN2.
The hoses should be secured with the supplied hose clips.
The Undercounter Unit should ideally be positioned directly below the Head unit installed position.
