1 THE MPE SERIES
1.1 FIELD OF APPLICATION
MPE air-condensed water chillers and heat pumps have been
designed to cool and heat water for air conditioning and heating
systems in residential or commercial buildings.
The MPE range units are intended for outdoor installation
(IP24 protection degree), in a position not accessible to the
public.
If protection grids are not provided (accessory) and if the ma-
chine can be reached by non-specialised personnel, access to
the nned coil must be prohibited using appropriate barriers.
Do not install the unit in environments with gas or amma-
ble dusts.
1.2 MAIN FEATURES
MPE water chillers and heat pumps are designed for outdoor
installation in both residential and industrial applications. The
range uses R410A refrigerant, which assures high levels of per-
formance with relatively low energy consumption and features
10 models in the chiller version and 29 models in the heat pump
version, with cooling capacities ranging from 9 to 76 kW and
heating capacities from 5 to 85 kW.
The nned block heat exchangers have been optimised for
R410A and use 8 mm copper pipes, which permit a better heat
exchange and quiet operation of the fans. Their generous sizing
guarantees the production of chilled water even with outdoor
air temperatures as high as 47°C.
In the MPET models, with a double compressor on the same
cooling circuit, the working temperature range is extended fur-
ther and eciency at partial loads increases.
In demanding working conditions the microprocessor controller
activates the capacity control mode, doubling the condensing
surface available to the single compressor.
The self-adaptive logic allows the setpoint to be adjusted au-
tomatically 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 auto-
matic adjustment which limits the number of compressor starts
and thus extends the life of the compressors themselves.
The exclusive Smart Defrost System (optional feature available
with the advanced controller) can correctly identify an impair-
ment of performance in the outdoor exchanger due to the for-
mation of ice and minimise the process time in relation to nor-
mal operation of the unit.

2 CONSTRUCTIVE FEATURES
STRUCTURE
Galvanised sheet steel structure treated with a polyester powder
coating (RAL9002) suitable for outdoor applications, for an at-
tractive look and eective resistance to corrosive agents.
Fastening devices are made of non-oxidizable materials, or car-
bon 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.
On request acoustic insulation can reduce the unit noise
emissions

2.8 FAN DRIVE ASSEMBLY
Electric fan with 6/8-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 prole de-
signed to optimise ventilation.
The use of nned block heat exchangers with 8 mm diameter
pipes reduces pressure drops on the air side, thus signicantly
improving the noise levels of the units.
The condensation control system continuously and automatical-
ly regulates the fan speed, further limiting the noise emissions
of the unit during nighttime operation and under partial load
conditions.

3 INSPECTION, CONVEYANCE DIMENSIONAL AND SITING
3.1 INSPECTION
On receiving the unit, check that the packing is intact: the ma-
chine left the factory in perfect conditions and after thorough
inspection.
Should you detect any signs of damage, immediately report
them to the carrier and note them on the delivery slip.
Galletti S.p.A. Must be notied of the entity of the damage with-
in 8 days of the delivery date.
Check that the following items are present:
Ū starting up module,
Ū wiring diagram
Ū warranty certicate
Ū make sure that this manual is intact (68 pagine).
3.2 CONVEYANCE
During handling it is compulsory to check dimensions, weights,
centre of gravity and anchorages. Check as well that lifting and
positioning devices conform to the current safety regulations.
The unit leaves the factory screwed onto a wooden pallet, which
allows it to be easily conveyed with a forklift truck. After remov-
ing the unit from the pallet, handle it gently, without applying
excessive pressure on the side panels, nned coil and fan grille.
You should collect and separate the packing materials (wood,
cardboard, nylon etc.) and make them available for recycling
in order to minimise their environmental impact. Before lifting,
remove the screws fastening the base of the unit to the wood
platform.
The unit must be lifted using Ø 1”steel pipes at least 5mm thick,
to be inserted in the round holes on the base side members (see
gure) and identied by means of stickers. Piping must protrude
of at least 250-300 mm from each side, be slung with ropes of
equal length and secured to the lifting hook (provide stops at
the ends of the pipes to prevent the ropes from slipping o due
to the weight).
Use ropes and belts suciently long to extend beyond the
height of the machine and place spacer bars and boards on the
top to prevent damaging the sides and the top of the unit.
In this phase, before the denitive position, vibration damping
supports can be installed (optional).
AWARNING In all lifting operations make sure that the unit
is securely anchored in order to prevent accidental falls or
overturning.
Use all available lifting points.
» Lifting points
3.3 SITING AND DAMPERS
It is important to bear in mind the following aspects when
choosing the best site for installing the unit:
Ū Size and origin of water pipes;
Ū Location of the power supply;
Ū Solidity of the supporting surface;
Ū Avoid obstacles to the outow of air from the fan which could
cause back suction (see section on 3.5Dimensionsp.14);
Ū Direction of prevalent winds: (position the unit so as to pre-
vent prevalent winds from interfering with the fan air ow).
Prevalent winds opposing the fan air ow will result in a
maximum air temperature below the value indicated in the
operating limits;
Ū Avoid the possible reverberation of sound waves; do not in-
stall the unit in narrow or cramped spaces;
Ū Ensure adequate accessibility for maintenance or repairs

3.4 INSTALLATION CLEARANCE
REQUIREMENTS
To guarantee the proper functioning of the unit and access for
maintenance purposes, it is necessary to comply with the mini-
mum installation clearance requirements shown in gures Spazi
installazione MPE H 04 - 08 , spazi installazione MPE 09-15 , spazi
installazione MPE H 18-27; MPE C T18-T25 , spazi installazione
MPE 28-40 - T30 - T42 and spazi installazione MPE T54 - T76 .
Ū Verify that there are no obstacoles in front of the fans air out-
let.
Ū Avoid any and all situations of backow of hot air between
air outlet and inlet of the unit.
Ū If even only one of the above conditions is not fullled,
please contact the manufacturer to check for feasibility.
Ū In the design of the MPE series, special care has been taken
to minimise noise and vibrations transmitted to the ground.
Ū Even greater insulation may be obtained, however, by using
vibration damping base supports (available as optional ac-
cessories).
Ū If vibration damping base supports are adopted, it is strong-
ly recommended also to use vibration damping couplings
on the water pipes.
Ū Whenever the unit is to be sited on unstable ground (various
types of soil, gardens, etc.) it is a good idea to provide a sup-
porting base of adequate dimensions.
AWARNING Heat pump units produce condensation while
operating in the heating mode.
