1.GENERAL CARACHTERISTICS
1.1 CLASSIFICATION
The machinery in the present manual is defined
as:
“Refrigerator and heating pump mono block air/
water”.
All water refrigerators are signed as RPE, the
heating pumps nominated HPE, with addition e
numeric code of the power in kW.
1.2 CERTIFICATIONS - MARK CE
RPE - HPE X are conform to the norms as
follows 97/23/CE, 98/37/CEE, 73/23/CEE, 89/
336/CEE, nd modified 93/68/CEE.
The machineries are tagged with mark CE and
its are tested in respect of the CE norms.
1.3 BUILDING CARACHTERISTIC
RPE/HPE X are created for out-door installation,
with protection class IP24 and feeding mono
phase 230V~ 50Hz (mod. 5÷17) or three phase
400V 3N~ 50Hz (mod. 10÷17): the models 10÷17
can be mono or three phased.
All appliances are equipped with a
microprocessor for the control and the regulation
of the work and safety of the units.
The adaption algorithm of the SET POINT –
function sliding of temperature of SET – and the
control of the partial mode (0/50/100%) of the
compressors tandem (mod. RPE-HPE X10÷17)
permits, often, the elimination of the tank.
The performance of the appliance are better
used by high energy efficiency values, using the
big surfaces of the thermo exchangers and the
thermo dynamic characteristics of gas R410a.
Other building features:
-the casing is realised with Inox steel AISI 304.
The compressor is insulated from the air/
refrigerant exchanger; this insulation
contributes of the protection of the electro-
mechanics components and of the low sound
level;
- the compressor is of rotary type on high
efficiency and low sound level, function with
refrigerant R 410a, mounted above elastic
supports anti-vibration, automated with
electrical mono phase motor;
- the exchanger air/gas refrigerant is realised
with cooper pipes and aluminium wings, high
surface of thermo exchange;
- the fan group is composed from 1 or 2 fans
helicoidally with exocrine motors mono phase
with internal protection. The fans are equipped
with a protection grille;
- the warm exchanger water/gas refrigerant,
on plates type from steel inox AIS I316, is
insulated with an external casing on closed
cellules to reduce the thermo dispersions;
- the cooling circuit and the connections
between the single components are realised
from cooper. In the cooling circuit are situated
the thermostatic valve, cycle inversion’s valve,
liquid’s separator and receiver (models heat
pump), pressure switch of low and high
pressure, filter dehydration;
- the electrical panel is situated inside the
machinery;
- the control system of the microprocessor is
easy to be reach.
1.4 PACKING CONTAINS
Packing – wood’s pallet, with plastic protection.
The technical data are reported on the external
tag.
The present manual and the warranty certificate
are inside the little box on compressor’s side and
should be delivered to the end user.
1.5 ACCESSORIES FROM FACTORY OR ON
DEMAND
The large range of accessories available from
factory or on demand improve the performances
of the appliance (Tab.1).
1.6 USE
The appliances are created for cooling and, or
heating of the water in the conditioning plants
and should be used only for this purposes.
WARNING! All other uses, not descript in
this manual, will be considerate as improper.
The manufacturer excludes any
responsibility for damage of person, animals
SECTION A - GENERAL INFORMATIONS

or goods due to non observance of the rules
and instructions of this manual – as
deformation of the product, not correct
installation, error of regulation and bad
maintenance.
The warranty will be cancelled by improper
use.
1.7 SAFETY
WARRANTY! Only skilled person is
authorized to make the installation and the
technical service of the machinery.
All norm for electrical feeding and
connections should be observed.
During the operation of installation and
technical service to observe safety
conditions and instruction from the manual.
Distance limits and electrical connections
should not be modified.
Before each technical intervention the
general electrical feeding should be switch
off.
