DECLARATION OF CONFORMITY

Galletti S.p.A., whose head office is located at 12/a Via Romagnoli 12/a Bentivoglio (Bologna) - Italy, hereby declares, under its own responsibility, that
the water chillers and heat pumps belonging to the series:
ECHO, ECHO H, MCA, MCA H, LCA, LCA H, MCC, MCC H, MCW, MCW-H, MPE, MPEH, MCE, MCEH, MFE and MXE, units intended for applications
in civil air conditioning systems, comply with the requirements of EEC Directives 98/37/CE, 89/336/CEE, 92/31/CEE, 93/68/CEE, 2006/95/CE,

97/23/CE (PED).

These units are the result of an assembly of components [compressors, brazed plate heat exchangers, liquid receivers, pipes, control and safety
valves] which are individually provided, where required, with certification in accordance with current directives: the category to which the machines
belong is determined on the basis of an analysis of the components subject to the PED and corresponds to the highest category among the
components used.
For each series of machines, the conformity of the assembly has been assessed by notified bodies, applying the assessment procedures (forms)
pursuant to annex II of the PED - Directive 97/23, as shown in the following table:

1 THE SERIES

Galletti has developed this product for the production of hot water for heating
systems - especially in demand for independent homes - with the aim of
reducing primary energy consumption and operating costs compared to
conventional gas or electric systems, thanks to a high level of efficiency:

average COP 3.33 (Eurovent Energy Efficiency Class A)
average EER 3.23 (Eurovent Energy Efficiency Class A)

OPTIMISED FOR OPERATION IN THE HEATING MODE

- Plate heat exchanger with reverse-flow operation in the heating mode
(+7% increase in efficiency).

- Finned coil with wide fin spacing

- Desuperheater in the pipes at the base of the finned block heat exchanger.

- Heating cable on the base in the internal part of the finned coil.

- Facilitated condensate drainage

YEAR-ROUND OPERATION

MXE heat pumps have been designed to work in the heating mode with

outdoor air temperatures ranging from -15°C to + 30°C, producing hot water
at temperatures of up to 55°C, and in the cooling mode with air temperatures

ranging from -10 to +45°C.

The electronic expansion valve and
condensation control (under pressure)
contribute to increasing the working range.

SMART DEFROST SYSTEM

The exclusive defrost system (optional feature available with the advanced
controller) can correctly identify an impairment of per formance in the outdoor
exchanger due to the formation of ice and minimise the process time in
relation to normal operation of the unit.

SELF-ADAPTIVE

The electronic control system allows the setpoint to be adjusted automatically
according to the outdoor temperature in order to reduce consumption and
broaden the working temperature range.
The unit can also function in systems with a low water content, even
without the use of a storage reservoir, thanks to the automatic adjustment
which limits the number of compressor starts and thus extends the life of
the compressors themselves.

2 CONSTRUCTIVE FEATURES

STRUCTURE

Painted galvanised sheet steel structure (RAL9002) for an attractive look and
effective resistance to corrosive agents.
Fastening devices are made of non-oxidizable materials, or carbon steel that
has undergone surface-passivating treatments.
The compressor compartment is completely sealed and may be accessed on
3 sides thanks to easy-to-remove panels that greatly simplify maintenance
and/or inspection.
Sound insulation, available on request, can further reduce the noise emissions
of the unit.

CUSTOMISED HYDRAULIC KIT

- High head pump made entirely of stainless steel, already configured for

use with mixtures of water and ethylene glycol up to 35% and provided
with internal thermal protection.
It is housed in the compressor compartment and is easy to reach thanks
to the removable perimeter panels.

- Expansion tank.

- Safety valve.

- Filling cock (included).

- Automatic vent valve.

- Water differential pressure switch and outlet water temperature probe with

anti-freeze thermostat function.

- Mechanical Y filter supplied as a standard feature on all models to protect

the evaporator (included).

- Buffer tank available on request.

COOLING CIRCUIT

- Scroll-type compressor housed in a compar tment that can be sound

insulated.

- Brazed plate heat exchangers made of STAINLESS STEEL and optimised

for use with R410A.

- Finned block condenser with 8 mm copper piping and aluminium fins,

characterised by ample heat exchange surfaces.

- Dehydrating filter.

- Flow indicator with humidity indicator.

- Electronically controlled electric thermostatic valve with dedicated driver

which controls opening according to the refrigerant pressure and
temperature downstream from the evaporator.

- Reverse cycle valve

- Single-acting valves.

- Liquid receiver.

- High and low pressure switches.

- Safety valve.

- Schrader valves for checks and/or maintenance.

- Refrigerant pressure gauges (optional)

FAN DRIVE ASSEMBLY

Electric fan with 6-pole external rotor motor directly keyed to the axial fan, with
internal thermal protection on the windings, complete with safety grille and
dedicated supporting structure.
The fan is housed in a special compartment having a profile designed to
optimise ventilation.
The use of finned block heat exchangers with 8mm diameter pipes reduces
pressure drops on the air side, thus significantly improving the noise levels of
the units.
The condensation control system continuously and automatically regulates
the fan speed, further limiting the noise emissions of the unit during nighttime
operation and under partial load conditions.

FINNED BLOCK HEAT EXCHANGER

Made of 8mm diameter copper pipes and aluminium fins, generously sized.
The special engineering of the heat exchangers allows defrost cycles to be
carried out at maximum speed in the models with heat pump operation, which
brings clear benefits in terms of the integrated efficiency of the whole cycle.

ELECTRONIC MICROPROCESSOR CONTROL

The electronic control enables the complete control of the MXE unit. It can be
easily accessed through a
polycarbonate flap with IP65 protection
rating.
The self-adaptive logic enables the unit
to operate even in systems where the
water content is low, without the use
of an inertial water storage reservoir.
By reading the outdoor air temperatu­re, it can automatically change the setpoint to adapt it to the outdoor load
conditions or keep the unit running even in the harshest winter conditions.
The basic controller comes complete with the MODBUS protocol and enables
an immediate connection to ERGO networks.
Main functions

- Control over the temperature of water entering the evaporator.

- Defrosting management

- Control of fan speed

- Complete alarm management.

- Dynamic control of the setpoint according to the outdoor air temperatu­re.

- Can be connected to an RS485 serial line for supervisory / teleassistance
operation;

12 WATER CIRCUIT

When setting up the water circuit of the unit, it is advisable to follow the directions
below and in any case comply with local or national regulations.

Connect the pipes to the chiller using flexible couplings to prevent the
transmission of vibrations and to compensate thermal expansions.

It is recommended to install the following components on the pipes:

- Temperature and pressure indicators for routine maintenance and monitor­ing of the unit. Checking the pressure on the water side will enable you to
verify whether the expansion tank is working efficiently and to promptly detect
any water leaks within the equipment.

- Traps on incoming and outgoing pipes for temperature measurements,
which can provide a direct reading of the operating temperatures.

- Regulating valves (gate valves) for isolating the unit from the water circuit.

- Metal mesh filter (supplied), with a mesh size no greater than 1 mm,
to be fitted on the inlet pipe to protect the exchanger from scale or
impurities present in the pipes.

- Air vent valves, to be placed at the highest points of the water circuit for the
purpose of bleeding air. (The internal pipes of the unit are fitted with small
air vent valves for bleeding the unit itself: this operation may only be carried
out when the unit is disconnected from the power supply).

- Drainage valve and, where necessary, a drainage tank for emptying out the
equipment for maintenance purposes or when the unit is taken out of service
at the end of the season. (A 1” drainage valve is provided on the optional
water buffer tank: this operation may only be carried out when the unit is
disconnected from the power supply).

It is of fundamental importance that the incoming water supply is hooked up
to the connection marked “Water Inlet”.

Otherwise the evaporator would be exposed to the risk of freezing since the
antifreeze thermostat would not be able to perform its function; moreover the
reverse cycle would not be respected in the cooling mode, resulting in additional
risks of malfunctioning.

The dimensions and position of plumbing connections are shown in the
dimension tables at the end of the manual.

The water circuit must be set up in such a way as to guarantee that the nominal
flow rate of the water supplied to the evaporator remains constant (+/- 15%)
in all operating conditions.
A standard feature of MXE units is a device for controlling the flow rate (flow
switch or differential pressure switch) in the water circuit in the immediate
vicinity of the evaporator.

12.1 SYSTEM WATER CONTENT AND CHARGING OF
EXPANSION TANK

In models without a water storage tank it is necessary to assure that the content
of water within the system does not fall below 4.5 litres/kW. This level is
necessary to prevent the water temperature from falling below the indoor unit
enabling threshold during defrost cycles.

N.B kW in reference to rated capacity

The expansion tank is pre-charged to a pressure of 1.5 bars, sufficient for
systems with a maximum height difference (H in the figure at the side) of 13
metres.
For greater height differences, refer to the table below in order to adjust the
charging pressure of the expansion tank accordingly.
In no case should you exceed the maximum height difference Hmax = 35 m.

13 ELECTRICAL DATA AND CONNECTIONS

- The maximum electrical input is the mains electricity that must be available in order for the unit to work.

- The maximum current absorption refers to the current that will trigger the internal safety devices of the unit.
It is the maximum current allowed in the unit. This value may never be exceeded; it must be used as a reference for determining the size of the power supply
line and the related safety devices (refer to the wiring diagram supplied with the units).
Cross-section area of cables: 4 A/mm2 approx.

15 INSTALLATION CLEARANCE REQUIREMENTS

To guarantee the proper functioning of the unit and access for maintenance
purposes, it is necessary to comply with the minimum installation clearance
requirements shown in figures 1 and 2.
There must be no obstacles blocking the path of the air flow from the fans.
Avoid any and all situations of backflow of hot air between air outlet and inlet
of the unit.
If even only one of the above conditions is not fulfilled, please contact the
manufacturer to check for feasibility.

MXE 09 ÷ 16

In the design of the MXE series, special care has been taken to minimise noise
and vibrations transmitted to the ground.
Even greater insulation may be obtained, however, by using vibration damping
base supports (available as optional accessories).
If vibration damping base supports are adopted, it is strongly recommended
also to use vibration damping couplings on the water pipes.
Whenever the unit is to be sited on unstable ground (various types of soil,
gardens, etc.) it is a good idea to provide a supporting base of adequate
dimensions.

Warning:

heat pump units produce condensation while operating

in the heating mode.

16 SITING

It is important to bear in mind the following aspects when choosing the best
site for installing the unit:

- size and origin of water pipes;

- location of the power supply;

- solidity of the supporting surface;

- avoid obstacles to the outflow of air from the fan which could cause back

suction (see section on “installation clearance requirements”);

- direction of prevalent winds: (position the unit so that prevalent winds do

not alter the fan air flow).
A prevalent wind blowing from a direction opposite to the fan air flow will
reduce the maximum air temperature to a lower value than specified in the
operating limits,
a wind blowing in the same direction as the fan air flow will increase the minimum
air temperature to a higher value than specified in the operating limits.
Also in the heat pump mode, wind may have the effect of reducing the unit’s
operating range.

- avoid the possible reverberation of sound waves (do not install the unit in

narrow or cramped spaces).

- ensure adequate accessibility for maintenance or repairs (see section on

“installation clearance requirements”).
