1.- BUILDING-IN.
The water heater shall be built-in as close as possible to the outlets in order to reduce the heat loses.
The building place must be chosen considering the maximum reductions of 90º elbows in water
connections and, at the same time, make easy the substitution of the heating element.
2.- APPLIANCE WALL HANG.
Due to its particular design, the NOFER electrical water heaters could be installed in two positions as you
could see at fig-2:
1. Vertical. At this position cold water inlet pipe (F) is on the right side and hot water outlet pipe (C) on the
left side. The hydraulic safety valve supplied with the appliance must be installed at the inlet cold water
pipe (F)..
2. Horizontal with maintenance cover on left side. In this case inlet cold water pipe (F) will be placed every
time in the bottom pipe and hot water outlet pipe (C) in the upper part. The safety valve must be installed
in the bottom pipe

SCxxxN_ES_EN_FR_IT_PT_ver1
11
Fig. 2 Model APARICI SCxxxN
In every case the distance between water heater maintenance cover and the closer wall must be minimum 60
cm.
It has to be fitted to the wall using appropriate rag bolts with minimum diameter of 8 mm. The wall with feeble
charging ability must be on the spot where the water heater shall be hanged suitably reinforced.
3.- CONNECTION TO THE WATER SUPPLY.
The water heater may be connected to a closed-circuit pressure system which enables several points of
use. For safety reasons the supply pipe must be fitted with a return safety valve or alternatively, a valve of the
safety class that prevents the pressure in the tank from exceeding the nominal pressure by more than 0.1 MPa.
The heating of water in the heater causes the pressure in the tank to increase to the level set by the safety valve.
As the water cannot return to the water supply system, this can result in the dripping from the outlet of the safety
valve. The drip can be piped to the drain by installing a catching unit just below the safety valve. The drain
installed below the safety valve outlet must be piped down vertically and located in the environment that is free
from the onset of freezing conditions. In case the existing plumbing does not enable you to pipe the dripping
water from the return safety valve into the drain, you can avoid the dripping by installing a 3-litre expansion tank
on the inlet water pipe of the boiler. You should ensure that the return safety valve is functioning properly by
checking it on a regular basis i.e. every 14 days. To check the valve, you should open the outlet of the return
safety valve by turning the. The valve is operating properly if the water comes out of the nozzle when the outlet is
open.

Putting into service:
Before connect hydraulically the water heater to water network lets the water flow some to time to remove
all dirty which could damage the safety valve and block the diffuser.
To fill the water heater properly leave a hot water tap open to drain the water heater tank and only close it
when water comes out fluently. When water become hot after the necessary time tight again all connections to
assure a correct water sealing.
If the water network pressure is higher than the nominal pressure of the water heater, it is compulsory to
install special valve to reduce the water inlet pressure between 2 and 3 bar.
4.- CONNECTION OF THE WATER HEATER TO THE ELECTRIC NETWORK.
The connection of water heater to the electric network must be performed according to standards for
electric installation and made by authorized installers.
These models must be connected to electrical network using a plug supplied assembled to the water
heater. According to this the sole necessary operation from electrical point of view is to plug the water heater to a
socked. If the flexible cord is damaged, it must be substituted by an especial plug cord APARICI reference 91027.
Because the water heater has no components which would permanently separate it from the electric
network, upon the cable connection between it and permanent installation a switch must be installed which
breaks both power supply poles having between the open contacts a gap at least 3 mm wide.
The below drawing shows the electrical water heater diagram:
Fig. – 4 APARICI – SCxxxN electrical diagram
5.- ELECTRICAL CONNECTIONS STANDARDS.
The electrical installation must fulfil the international standards CEI 64-8. According to this standards,
electrical appliances must be installed following the below indications at bathrooms and WC:
1.- zone 0: Installation is totally forbidden at this area. It is also forbidden at zone 1 if it is a prefabricated shower
cabin.
2.- zones 1 and 2: IPX4 appliances with a wire which allows connections 1,2 m from shower vertical and with an
additional RCS switch.
3.-zone 3: IPX1 appliances allowed.
4.- The earth connection of the water heaters is compulsory.
We recommend the installation of the water heaters at zone 3 (fig.- 5).

6.- INSTALLATION RECOMMENDATIONS
In order to have a correct operation of the APARICI electric water heater, please take into account the below
considerations:
1. Water pressure at electric water heater inlet must be between 1.5 and 5 bar. Also all considerations explained
at point 3) of this manual must be taken into account.
2. It is compulsory to install a drain pipe to evacuate water drops from safety valve. Possible damages caused
at home due to this drops are not responsibility of APARICI.
3. If water pressure is higher than 2.5 bar we recommend the installation of a pressure reduction valve and a
expansion vessel. The pressure reduction valve must be installed as close as possible from the house water
inlet pipe.
4. The network water must have a minimum quality characteristics to be acceptable under corrosion point of
view. The limits established by APARICI are the below ones:
•Ryznar index less than 7.
•Conductivity at 25 ºC < 350 µ/Ω⋅cm
•Chlorine (Cl-) and sodium (Na+`) less than 75 mg/l
5. The use of chemical scale eliminators is allowed but the hardness must be regulated between 18ºF and 31
ºF.

IMPORTANT: Be sure that the water heater is filled with water before plug in. You could be sure that the
water heaters if completely filled when water come out from a hot water tap.

1) Plug in the electric water heater to electrical network using the plug cord assembled to the appliance.
At first time the power is connected, the screen lights, and shows ”CL”, after 1s the screen lights off
and water heater remains into stand by state.
2) ON/OFF: Press the “POWER” button ( ), water heater switches on, and the screen shows that
temperature can be selected, if no other operations within 3s, then can be shown the actual
temperature of tank. Press again the “POWER” button, water heater switches off.
3) Setting temperature: Press "+" or "-" button to set the desired temperature inside the tank, each time
your press button temperature increaser or decrease 5 ºC in a range between of 30 to 75 ºC. After
setting the temperature the display shows the current tank temperature.
4) To setting water heater power press "P" button. Below you can find the meaning of each display
indications:
•‘01’ => 800 W

•‘03’ => 2000 W
2.- CLEANING.
The external parts of the water heater may be cleaned with a mild detergent solution. Do not use solvents and
abrasives.
Never try to repair any possible faults of the water heater by yourself, but inform about it the
nearest authorised service workshop.
3.- WATER HEATER DRAIN IN CASE OF FROST
At any risk for freezing of water in the water heater, the water must be emptied from it. In order to do it,
please follow the below instructions:
oUnplug the appliance from electrical network.
oClose the water inlet to the water heater.
oDrain the water heater using the safety valve..
oProtect the safety valve from freezing.
oFill the water heater before plug in it again to electrical network.
4.- TROUBLE SHOOTING
When the water heater fails, automatically the heating element stops working and the display shows the
corresponding fault code. At that moment, if you press any button, there is not answer from the water heater. Only
disconnect the power, call to after sales service to solve the problem and repair the water heater and connect it
