2 SAFETY

This appliance is not destined for use by anyone (including
o
children) with reduced physical, sensorial or mental
capacities or those who do not know how to use the
appliance, unless they are supervised or instructed by a
person responsible for their safety.
Check that the voltage on the indicator plate of the boiler
o
coincides with the voltage of the mains circuit to which it
is going to be connected.
The use of these boilers in the presence of gases,
o
explosives or inflammable objects is prohibited.
The air inputs and outputs of the boiler ensure its correct
o
operation and protect it from over-heating. They must
never be covered.
This boiler must be disconnected from the mains
o
electricity before carrying out any internal repairs.
The boiler must be installed in such a manner that the
o
switches or other controls cannot be touched by anyone
who is using the bath or shower.
The installation must be performed in accordance with
o
current electricity regulations.
This appliance is destined to be permanently connected to
o
a fixed installation. The power circuit of the boiler must
incorporate an omni-polar cut-off switch with a
separation between the contacts of at least 3 mm.
The electricity supply circuit must incorporate a Residual-
o
Current Device.
This boiler must be earthed.
o
All the models incorporate different safety elements. If
o
one or more of them are activated, consult the section 7
TROUBLE SHOOTING.
In time, the presence in the air of smoke, dust and
o
pollution may stain the walls and areas close to the

3 INTRODUCTION

3.1 DESING & OPERATION
The Gabarrón MATTIRA CMX18i and CMX15i combi boilers
are electrically heated appliances providing wet central
heating through a standard radiator system (or underfloor
system with special kit) and domestic hot water (DHW)
delivered from an integral unvented store at mains water
pressure.
Outputs are from 2 to 18kW. Maximum output can be
adjusted to match the heat requirement of the system or the
limitations of the incoming available power supply. Operation
is possible on three phase 3x400V+N or single phase 230V –
(Standard configuration allows a maximum of 12kW in single
phase mode).
The boilers are designed for internal installation on a suitable
wall with consideration for the total weight of the appliance
when full.
A digital control panel provides user control to adjust the
temperatures of heating and hot water. A power modulation
feature automatically adjusts the heating output to the
demand to ensure economic operation. A suitable external
time clock/room thermostat should be fitted (not supplied).
All components for sealed system central heating are built-in.
Heating and hot water functions will operate independently
but not simultaneously, with priority always to hot water
production.
