1. DESCRIPTION AND CHOICE
OF THE UNIT
The OUTDOOR air-cooled heat pumps in the ANK
range with R410A, have been designed and
manufactured to satisfy the heating/cooling and
production of DHW requirements of small to medium
utilities in residential or commercial buildings.
The units are characterised by extremely silent
operation and are highly efficient and reliable, thanks
to the use of exchangers with a large exchange surface
and low-noise high-efficiency scroll compressors.
The following versions are available:
1. ANK "H" Wärmepumpe 
At the same time, the versions are available with
different set-ups in order to satisfy a wide range of
system solutions:
1. "°" BASE
2. "P" PUMP ONLY 
3. "A" STORAGE TANK AND PUMP

motor. All compressors are fitted with guard resistance,
internal electronic circuit breaker protection with
centralised manual rearm.
SYSTEM SIDE HEAT EXCHANGER
Braze welded AISI 316 steel plate exchanger, insulated
externally with closed cell neoprene anti-condensation
material. It is fitted with an anti-freeze electric
resistance as per standard.
5.1.1. WATER FEATURES

SOURCE SIDE EXCHANGER
Finned pack heat exchanger made with copper pipes
and aluminium fins adequately spaced to ensure high
efficiency.
CYCLE REVERSING VALVE
4-way cycle reversing valve. Inverts the flow of refriger-
ant fluid.
LIQUID STORAGE TANK
It compensates the difference in volume between
finned coil and plate exchanger, retaining excess liquid.
DEHYDRATOR FILTER
Hermetic with ceramic and hygroscopic material
cartridge, able to withhold impurities and any traces of
humidity present in the cooling circuit.
NON-RETURN VALVES
Allow one-way flow of the fluid.
THERMOSTATIC VALVe
Mechanical, with external equaliser positioned at
evaporator outlet, modulates the flow of gas to the
evaporator, depending on the heat load, in order to en-
sure a correct heating level of the gas in the intake line.
SOLENOID VALVE
The valve closes when the compressor switches off,
blocking the flow of refrigerant gas to the evaporator.
LIQUID INDICATOR LED
Used to check the correct power supply of the lami-
nating element and any presence of humidity in the
cooling circuit.
LIQUID SEPARATOR
Positioned in the intake line, it protects the compressor
from any liquid return.
5.2. STRUCTURE AND FANS
STRUCTURE
Support structure made of hot-dipped galvanised
steel sheets, painted with polyester powders, built to
guarantee easy accessibility for service and
maintenance.
FAN UNIT
Fied with accident-protecon protecve mesh and
made up from 6-pole motor axial fans with external
rotor with IP44 protecon rang. The motor is also
fied with internal manual-rearm circuit breaker
protecon. It is in compliance with the
IEC EN 60335-2-40 Standard.
5.3. HYDRAULIC CIRCUIT
WATER FILTER
Fitted with steel filtering mesh that keeps the
exchanger from clogging by impurities present in the
circuit.
FLOW SWITCH
It has the task of controlling the correct water
circulation inside the heat exchanger; if this is not the
case, they block the unit.
SAFETY VALVE
Calibrated at 6 bar, it has conveyable discharge and
intervenes by discharging over-pressure in the event of
anomalous pressures.
AIR VENT VALVE
Manual, it discharges any air bubbles present in the
hydraulic circuit. It is cut-off by a cock in order to
facilitate any replacement.
5.3.1. ADDITIONAL COMPONENTS ENVISIONED
BY THE CONFIGURATOR
PUMP
Offers a useful head to the system, net of the unit
pressure drops.
EXPANSION VESSEL
A membrane with factory-set nitrogen (see technical
data for capacity).
SYSTEM STORAGE TANK
Used to decrease the number of compressor peaks and
even out the temperature of the water to be sent to
the system.
Made of steel to reduce heat loss and to eliminate
the formation of condensation, insulated by thick
polyurethane.
It mounts a range of 200 W electric anti-freeze
resistances able to ensure a minimum temperature
of the stored water of +5°C with minimum outdoor
temperature of -20°C. The resistances are activated by
the anti-freeze probe inserted in the tank.
DRAIN COCK
Allows to drain circuit water.
5.4. SAFETY AND CONTROL
COMPONENTS
HIGH PRESSURE SWITCH
With fixed calibration, placed on high pressure side

10 Aermec code 6755521_01 11.11
ANK 025-085H
of cooling circuit, inhibits compressor operation if
abnormal work pressure occurs.
LOW PRESSURE TRANSDUCER
Positioned on the low pressure side of the cooling
circuit, it informs the control board of the
work pressure, generating a pre-alarm
in the event of anomalous pressure.
HIGH PRESSURE TRANSDUCER
Positioned on the high pressure side of the cooling
circuit, it informs the control board of the
work pressure, generating a pre-alarm
in the event of anomalous pressure.
5.5. ELECTRIC CONTROL
AND POWER BOARD
ELECTRIC CONTROL BOARD
In compliance with the EN 60204-1/IEC 204-1
Standards, complete with:
- door lock main isolating switch,
- magnet circuit breakers and contactors for
compressors and fans,
- clamps for REMOTE PANEL (accessory),
- spring type control circuit terminal board,
- outdoor electric control board with panel and
gaskets,

- evaporator pump consent relay,
- all numbered cables.
DOORLOCK ISOLATING SWITCH
The electric control board can be accessed by removing
the voltage using the door lock isolating switch lever.
The isolating switch is fitted with a safety lock to
prevent voltage being applied to the machine
accidentally during maintenance operations.
CONTROL KEYBOARD
Allows complete control of the appliance. For a more
in-depth description please refer to the user manual.
Electronic modu control
ADJUSTMENT
Temperature control of the outlet water with proporonal-integral
algorithm: maintains average output temperature at value set
−Self-adapng differenal switch: guarantees minimum operang
mes of the compressor in systems with low water content.
−Intelligent defrosng for pressure reducon: opmisaon of the
defrosng cycles in order to prevent useless defrosng and to
increase the efficiency in heang mode.
−Set-point compensaon with external temperature (with external
air probe accessory): reduces energy consumpon.
−Condensaon check based on the pressure rather than on
temperature for absolute stability (with DCPX fan revs. adjuster
accessory).
−Inverse condensaon check for the heat pump operang mode also
in summer, producon of DHW (with DCPX fans revs. adjuster
accessory).
−Pre-alarms with automac reset: in the case of alarm, a certain
number of re-starts are allowed before the definive block.

blocked cycle reversing valve.
−Compressor operang hours count.
−Compressor peak count.
−Historical alarms.
−Autostart aer voltage drop.
−Local or remote control.
