Mounting; Water Supply Network Connection - Hyundai H-SWS1-30V-UI069 Instruction Manual

Mounting

The electrical water heater shall be installed on a irm wall.
The wall planned for installation of the electrical water heater shall be
capable to bear at least double weight of the water heater fully illed with
water. The wall shall be free of cracks and other damages. Otherwise,
take measures to reinforce the mount or install the water heater on a
special support.
If the bathroom is too small, the water heater can be installed in another
place not exposed to direct sunlight and inaccessible for moisture
ingress. However for reduction of heat loss in pipes, the installation place
of the water heater shall be located as close as possible to the hot water
consumption point.
When selecting a location for the water heater, ensure free access to it as
follows: at least 60 cm between the bottom part of the water heater and
loor; at least 10 cm between the top part and ceiling. This will ensure the
maximum comfort for maintenance and adjustment of the water heater,
when necessary.
Ater you have selected the proper place for installation of the water
heater, mark points to make holes for the anchor bolts with hooks. Drill
two holes of appropriate depth in the wall using a drill with suitable size
for the anchor bolts provided in the water heater package.
Ater that, insert the bolts to the drilled holes and rotate the hooks of the
bolts clockwise to securely tighten the nuts of the bolts. Then, hang the
water heater onto the hooks of the anchor bolts and check security of
EN mounting.

Water supply network connection

The water heater is connected to the cold water supply network with operating pressure from
0.1 MPa to 0.7 MPa. If water pressure in the water supply network exceeds 0.75 MPa, install a
reduction valve (pressure reducer) in the feed system so that operating pressure does not exceed
0.75 MPa.
If water hardness in the water supply main exceeds 450 mg/l (CaCO3), we recommend you
to use a separate water ilter upstream of the water heater inlet to extend service life of the
heating element.
For connection to the water supply network, the water heater has inlet and outlet connectors,
which are marked with indication labels and provided with male thread 12 mm in diameter
(G1/2").
Install the combined check valve / pressure safety valve provided in the package onto the cold
water inlet connection marked with blue color. Connect a drain tube to the pressure relief port of
the pressure safety valve for water drainage to the sewers (possible upon heating).
To facilitate maintenance of the water heater, we recommend you to install a drain valve and a
tee between the cold water inlet connection and pressure safety valve. This tee will help you to
faster drain water from the water heater. For your convenience, we recommend you to connect
a water drain hose to the shutof valve of the tee. This hose will allow you to route water drained
from the water heater to the sewers or another selected destination. Connect the desired
quantity of consumption points to the hot water outlet connection marked with red color. Open
CAUTION!
Never operate the water heater without the installed check
valve / pressure safety valve.
