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mOW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.

• Ensure that national safety code requirements have
been followed for the main supply circuit.
• Follow all current national safety code requirements.
• Ensure that a properly sized and connected ground
wire is in place.
• Check that voltage and frequency of the mains power
supply are those required;the available power must
be adequate to operate any other possible appliances
connected to the same line.
• Check that the impedance of the mains power supply
is in conformance with the unit power input indicated
in the rating plate of the unit (EN 61000-3-12).
• Make sure that properly sized disconnecting and
safety switches are installed closed to the unit.
• The disconnection devices from the mains supply
must allow full disconnection under the conditions
provided for by overvoltage class III.
CAUTION
• Connect the connecting cable correctly.If the

controlled that allows fast installation with the aid of a few
external components.The SHERPA 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.Figure 10 describes the integrated components in
THEIRVARIOUSCONlGURATIONS
NOTE: The correct dimensioning of the expansion vessel
is left to the installer as a function of the type of plant.
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.

Anti-seizing pump
The units SHERPA 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 off 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 through the drain unit valve,Fig 9,
item 3,and the system drain, Fig 10,item 5.

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-off valves to allow
isolation of the most important circuit components,as
well as the heat exchanger itself.

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

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

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.
