Electrical storage water heater

5. MAINTENANCE

CAUTION!

Refer to «Water heater safe operation and installation rules»

Check the electrical plug and socket as oen as possible. Secure electrical contact and proper

grounding shall be assured. The plug and socket shall not heat up abnormally.

If the water heater is not used for a long period, especially in regions with low ambient tempera-

tures (below 0°C), water shall be drained from the water heater in order to prevent its damage

(due to water freezing in the internal tank).

To ensure reliable operation of the water heater for a long time, periodically clean the internal

tank and remove deposits from the electrical heating elements of the water heater. In addition,

periodically check condition of the magnesium anode (whether it is fully dissolved or not) for

its timely replacement with a new one in case of full dissolution. The tank cleaning frequency

depends on local water hardness.

CAUTION!

The manufacturer provides an extended warranty, when preventive main-

tenance operations are carried out (refer to the warranty card).

Cleaning shall be carried out by specialized service departments. The address of the nearest

service center can be obtained from the vendor or at www.hyundai-hvac.com. Preventive mainte-

nance operations shall be carried out with strict observation of the instruction manual and safety

rules.

The water heater is equipped with a thermal switch, which will cut o supply of electrical energy

to the electrical heating element in the event of water overheating/absence in the water heater.

If the water heater is switched on, but water is not heated, this means tripping or need for

reset of the thermal switch. To return the water heater to the operational condition, proceed as

follows:

- disconnect the water heater from power supply and remove the molding of the bottom cover;

- press the button at the center of the thermal switch until the button clicks;

- if the button is not pressed and there is no click, wait until the thermal switch cools down to the

initial temperature.
