1  INTRODUCTION
1.1 - R-410A - General info
• This air conditioner adopts the new HFC refrigerant
(R410A) which does not destroy ozone layer.
• R-410A refrigerant operates at 50%-70% higher
pressures than R-22. Be sure that servicing equipment
and replacement components are designed to operate
with R-410A.
• R-410A refrigerant cylinders have a dip tube which
allows liquid to ow out with the cylinder in a vertical
position with the valve at the top.
• R-410A systems should be charged with liquid
refrigerant. Use a commercial type metering device in
the manifold hose in order to vaporize the liquid
refrigerant before it enters in the unit.
• As for other HFC, R-410A refrigerant is only compatible
with oils recommended by the compressor
manufacturer.
• A vacuum pump is not enough to remove moisture from
oil.
• Oils absorb moisture rapidly. Do not expose oil to
atmosphere.
• Never open system to atmosphere while it is under
vacuum.
• When the system must be opened for service, break
vacuum with dry nitrogen.
• Do not vent R-410A into the atmosphere.
Use this unit only for factory approved applications.
The capacity and unit code are stated on the nameplate
data.
CAUTION:
• Do not leave system open to atmosphere any longer
than minimum required for installation.
• Oil in the compressor is extremely susceptible to
moisture absorption.

5.5 - Hydronic module (Fig. 9/10/11)
The MCI__H units are equipped with an integrated
hydronic module with a variable ows pump self-controlled
that allows fast installation with the aid of a few external
components. The MCI__X units, on the other hand, do not
have a circulation pump and expansion vessel.
For this reason, they must be provided outside. In any case,
all the necessary protections and valves are to be inserted in
the water circuit inside the unit.
Refer to Figure 9 for the exact connection of the water
pipes. Figures 10 and 11 describe the integrated components
in their various congurations.
NOTE: The correct dimensioning of the expansion vessel is
left to the installer as a function of the type of plant.

Anti-seizing pump
The MCI__H units are equipped with protection against the
seizing of the pump motor shaft. To allow this function, do
not empty the system or disconnect the power during long
periods of inactivity.
In any case, if the pump rotor shaft seizes after a long period
of inactivity, the user must do the following to unblock it:
- Disconnect the power.
- Remove the front panel.
- Unscrew the shaft-protection plug on the back of the
pump.
- Insert a screwdriver in the slot and turn the rotor shaft.
- Remount the protection plug.
- Reconnect the power.
System cleaning and water characteristics
In the case of a new installation, or cleaning the circuit, it
is necessary to perform a preventive cleaning of the system.
In order to guarantee the good operation of the product,
each time you clean the system, replace the water or add
glycol, check that the liquid appears clear, without visible
impurities and that the hardness is less than 20 °f.
Anti-freeze protection
If unit is switched o during the winter period when outdoor
air temperatures below 0°C can occur and ethylene glycol is
not used, it is recommended that the entire system is drained
NOTE: The discharge of the safety valve can be channelled
to the outside of the machine using the pre-cut holes (see
Fig. 4). In this case, it is necessary to provide an open drain
funnel.
6  WATER CONNECTIONS FIG. 14/15
Make the plate heat exchanger hydraulic connections
with the necessary components, using material which will
guarantee that the screwed joints are leak-proof.
The gures 12 and 13 show a typical water circuit installation.
For an application with a water circuit, the following
recommendations must be taken into account:
1. The external circulation pump must be installed in the
return water pipe work immediately before the heat
pump (unit without hydraulic module).
2. It is advisable to install shut-o valves to allow isolation
of the most important circuit components, as well as the
heat exchanger itself.
These valves (ball, globe or buttery valves) should
produce a minimum pressure drop when they are open.
3. Provide unit and system drains at the lowest system
point.
4. Install purges in the higher sections of the installation.
5. Pressure ports and pressure gauges should be installed
upstream and downstream of the external water pump.
6. All piping must be adequately insulated and supported.
Installation of the following components is obligatory:
1. The presence of particles in the water can lead to
obstructions in the heat exchanger.
It is therefore necessary to protect the heat exchanger
inlet with an extractable mesh lter. The lter mesh
gauge must be at least 10 mesh/cm2.
2. After assembling the system, or repairing the circuit, the
whole system must be thoroughly cleaned with special
attention paid to the state of the lters.
3. Pump ow rate control is made through a ow control
valve, which must be installed on the delivery pipe
during installation.
4. When water has to reach temperatures below 5°C, or the
equipment is installed in areas subject to temperatures
below 0°C, it is necessary to mix water with inhibited
ethylene glycol in suitable quantity.
