TECHNICAL AND DIMENSIONAL
SPECIF
ICATIONS
2.1
Operating
principle
The air-water
heat pump
uses
the
energy
of the air existing in the environment.
The
air required fo
r
the proper operation of the
heat
pump
can be
drawn from the
outside through a window
(mini
mum
temperature
-20°C)
or from the surroun
ding environment
or from other
environments
through ducts.
The
air drawn from the environment
is sucked
through a fan and the heat
existing
in air
is
absorbed
during the
passage
in
a heat exchanger (evaporator).
In the
evaporator
the
heat taken
from the
air
is
caused
to evaporate at low
pressure
by the refrigerant (the working fluid in the refrigerant circuit,
is as in a household fridge).
The vaporized
coolant is
sucked
by a
compressor
and raised to a
higher level of pressure (as
in
a bicycle
pump)
and temperature.
In
a second heat exchanger
(condenser)
the higher
temperature
heat
is absorbed
and
transferred
to the
water;
this
way
the
Cool Energy EcoStore Heat Pump Water Heater
7 | P a g e
vaporized
refrigerant fluid
switches back
to the liquid
state as a
consequence
of thermal
dissipation.
The
liquid
refrigerant, fl
owi
ng through a choking component
(expansion valve), undergoes
a low
pressure expansion and, after
returning to the
evaporator,
it
can again draw heat
from the
surrounding
environment.
The
hot
water heat
pump
operates at ambient temperatures ranging between
-20°C and +43°C.
The hot water heat pump is a
connection-ready
equipment whose function
is
heating drinkable
water;
it
basically consists
of the water tank and of the
refrigerant,
air and water circuit
components,
as well
as
of
all
the co
ntrol,
adjustment
and
monitoring
devices required
for
automatic
operation.
> Use of the environment energy
Refrigerators, washing machines,
heating
systems and
other equipment/electric
appliances
generate
heat that in most
cases
is not reused. Instead
of being
dispersed
into the environment, generating
pollution, the hot air in question can suitably be
used
to heat sanitary water: a
sensible
and
environment-friendly
solution.
An
important benefit
is
the
air
dehumidification
resulting
from
heat suction, decreasing
the
degree
of
humidity in
cellars and
laundries.
This has
two
beneficial effects: environment
prote ction
and
production of
cheap
hot
sanitary
water.
2.2
Energy efficiency
> Free energy
The necessary energy
for the heating of
sanitary
water
comes
for 2/3 from the air and 1/3 from the
electric
power supply.
> Coo
ling through
the heat pump for
hot
sanitary
water
After heat subtract
ion,
the lower-temperature output air can be
used
during
summer
to cool th
e
environment where
the
heat
pump
is
installed.
This provides a
double
benefit,
while
ensuring
optimum
energy
efficiency.
> multi
use of
energy
The heat pump can be beneficially installed in stores, workshops, commercial, residential
applications etc. to get hot
sanitary water and,
if needed, cooled air.

3.1
Hydraulic connection
Installations must conform to local
regu
lations in force. We recommend the integration of a
magnetic filter for the cold feed water supply. The link
pipes
(hot water,
recycle,
in-out
exchanger)
must
be perfectly isolated according
to the
energy norms
in
order
to avoid
heating
dispers
ions.
We recommend
that you install the equipment
close
to the
main
hot
water
drawing point, to prevent
heat
dispersions
along
pipes,
and if possible, near a drain, for
easier
emptying and condensate

interrupting
device.
The above components are required to
safely
run the supplied equipment. The rated calibration
pressure
of the hydraulic
safety
unit must be of
0.6 MPa
(6
bar). Pay
attention while installing the
hydraulic safety
unit,
avoiding forcing or altering it. Water may drip from the hydraulic safety un
it
discharge connector (see paragraphs
“USAGE INSTRUCTIONS
(user) - Water dripping from th
e
hydraulic
safety unit”).
This
opening must
be left
exposed
to the atmosp
here.
You
need to install a
discharge
pipe, with a constant downward
slope, in a
condensate-
and
ice-free area. There
must be
no
obstructions
in the
pipe,
to
avoid overpressures.
3.1.2
Pressure
reducer
Should the network
pressure exceed 0.6 MPa
(6
bar),
you need to install an appropriate pressure
reducer upstream
of the
hydraulic safety unit,
ensuring
the
indicated operating
range.
3.1.3
Expansion
tank
To prevent any
overpressures
that might
damage
the equipment, frequently triggering the safety
unit and causing water
dripping,
Uit is mandatoryU that you install an adequate
expansion
vess
el.
Install it in
accordance
with the instructions provided by the manufacturer. The expansion
tank is
required
to
keep pressure
constant and avoid harmful
pressure shocks
or
accidental overpressures.

will
be mixed by the bottom cold water which is continually flow from inlet tap water so that will
decrease
the upper part temperature.
D.
Why sometimes
the
temperature shown
on the
display decreased
but unit st
ill keep closed?
R.
To avoid unit

MAINTENANCE INSTRUCT
IONS
(qualified personnel
only)
WARNING:U
the
repair
and/or
maintenance operations must only be performed by
qualifiedU
U
personnel, exclusively
using genuine spare parts. Before
performing
any maintenanceU
U
operat
ions, disconnect the equipment from the mains.
U
Before performing

Manufacturer.
5.1 General
•
Control regularly
the
connection between
the
supply
plug
and wi
ring.
• In
some
cold
areas
(under
0°),
if the system
is
not
used
for a long period, empty the boiler in
order
to
avoid
freezing.
• It
is advised
to
clean regularly
the
inside
part of the boiler
and
the
electric resistance
in order
to
preserve
the efficiency.
•
Control
the
magnesium anode and change
it if
needed.
•
Clean
the
air filters
each
month in
order
to
preserve
the
heating
performance.
•
Before
turning off the
system
for a long period
you must:
-
Remove
the
current
supply;
-
Drain
all the
water
from the
tank and
the pipes;
-
Close all valves;
-
Control regularly all inside
components.

5.2
False errors of
operation
•
Due
to a start
caused
by a voltage
fall,
you must wait 3 minutes before the
reactivation
of the
compressor,
in
order
to
preserve its integrity.
•
If
the
auto
protection
is
activated and
the
system stops,
control
that:
-
When
the supply indicator is on, if the
system
is being forced to function
even
without the
normal
operative cond
itions; if the in-out air flow
is
blocked or if a strong wind blows
towards
the
air
exit.
•
De-frosting
When
there
is
humidity and cold,
the
condenser must be thawed and the
efficiency
of the air
heating
is lower:
the
system
will stop the water heating, will do the thaw and then will restart
the
air
heating.
•
During
the defrosting,
the
compressor co
ntinues to
work,
while the
fan
stops.
• The
defrosting
time varies between 3 and 10 minutes accordingly to the environmental
temperature and
frosting.
5.3
Visualized
temperature
•
When
the
system is stopped, a
reduction of the temperature
is
normal due to the
loss
of heat.
When
it
goes
bellow a few
degrees,
the
system is
automatically
activated.
• During the heating the water temperature could continue to
decrease
or could not increase
because
of the
exchange
water
heating. When
the whole tank will get to the
temperature
the
system
will
stop
auto matically.
5.4
Refrigerating unit
ma
intenance
The
refrigerating circuit requires
no maintenance.
Components are cleaned
during the
anode and tank
maintenance.
5.5
Cleaning the aspiration air
filter
Periodically
the filter
placed
in the
air
entry opening
is removed
and
cleaned
in order not to
damage the
system
efficiency.
Rotate
in
counterclockwise
sense
the
air entry
opening.
Lift
and remove
the opening.
Cool Energy EcoStore Heat Pump Water Heater
29 | P a g e
Lift the filter
and clean
it from
possible impurities. Put
again
the
cleaned
filter
and
the opening
before
rest
art
the equipm
ent.
5.6
Water circuit / Condensate discharge
The
water circuit
check is
limited to the integrated filter
installed
by the
customer
(if any;
in this cas
e
follow the
instructions
provided by the
valve manufacturer); also check
the
tightness
of the
valves,
of
the
screw connections, etc.; should they
be loose, have
them tightened by
technicians.
As
to the
condensate drain,
you
have
to
check
its operation, the
condensate
elimination (transparent
plastic
pipe),
the tightness and the
presence
of any impurities at the pipe ends, cleaning them
if
needed.
5.7
Air circuit
supply
Maintenance operations
only include the
cleaning
of the
evaporat
or,
when
needed
or at the end of
each shift, when checking
the
protective
magnesium anodes.
WARNING: UDanger of injuries due to the presence of sharp edge blades. The blades must
notU
Ube
deformed or
damaged –
(comb blades of
the condense
r).
5.8
Descaling and limestone deposit
removal
(periodic)
Since almost anywhere deposits
of
limestone
can
be formed, verify the infiltrations of dirty water and
for hygienic moti
ves,
the
inside
tank should
be controlled and
checked
by a qualified
person
at leas
t
after
the
first 2
years
of
use,
but
however when
the production of hot
water
decreases.
The limestone deposits reduce the tank volume,
so
also the transmission capacity of the heat
exchanger and
the production of hot
water are
reduced.
Maintenance must be done
by
qualified
pers
onnel.
For an accurate and
competent
maintenance
of the
inner tank
it
is necessary
to
have free access
to th
e
flange
in
order
to control
and clean
the inner boiler.
Cool Energy EcoStore Heat Pump Water Heater
30 | P a g e
For a correct and competent
maintenance,
it is
necessary
to evacuate/ leak the refrigerator circuit (
draining
and
filling)!
5.9
Anode ve
rification
(periodic)
The device is
protected
against corrosion
by
an electronic anticorrosion anode
for protection
against
the
effects
of
spurious currents
that
could damage it.
The
control is
performed
without
clearing
out the tank.
You must replace
the
anode
in
case
of wrong working.
CAUTION: Ua wrong functionality of the anode reduces the last of the
device.
