USE AND MAINTENANCE

Once you have connected the water heater to the water line and the electric network, the

water heater is ready for operation.

By turning the thermostat knob attached to the front of the protective cover, choose the

desired water temperature between 25°C and 75°C. We recommend the setting position

"e". This is the most economical setting where the water temperature is about 41°C for

KRO/KRU 0520 or 35°C for KRO/KRU 1020. Calcification and heat loss are lower with this

setting than at higher temperatures (item II 55 °C and III 75 °C).

Due to the temperature regulator hysteresis (±7 K) and potential radiation losses (cooling

of the plumbing), the temperatures quoted are subject to a tolerance of ± 10K.

The operation of the water heater is indicated by a control lamp, which illuminates until the

water in the unit has reached the desired temperature or the water heater is switched off.

When the water is heated, its volume changes. With a pressure-free connection, the

excess water therefore drips out of the mixed tap. Do not try to prevent this dripping (e.g.

by tightening the mixed tap), since this may result in damage to the mixed tap.

If the unit is put out of action or remains unused for a lengthy period of time, then it must be

drained and completely isolated from the power supply.

In rooms permanently subject to frost damage, the water heater must be drained before

the start of the cold weather season if the device will be out of action for several days and

is not being operated in frost protection mode " ".

Do not use any scouring agents to clean the device and do not use any paint thinners

(such as Nitro, trichloride, etc.)

It is best to clean it using a damp cloth with a few drops of a liquid household cleaning

agent. In hospitals and other public buildings, it is essential to comply with the prevailing

regulations for cleaning and disinfection.

Flawless functioning and a long service life are ensured by regular service. The first check

is to be performed by an expert after about 2 years of operation. During this check, the

corrosion protection anode is checked and limescale is removed if necessary. The amount

of calcification depends on the water quality, the water quantity and the water temperature.

Based on the determined amount of calcification after 2 years of operation, the expert will

recommend the time for the next inspection.

We ask you to not repair any faults of the water heater yourself, but rather to inform

the nearest customer service representative.
