Alpha innotec heating elements Owner's manual

Brand: Alpha innotec

Model: heating elements

Type: Owner's manual

Alpha innotec heating elements allow you to heat water for various purposes, such as domestic hot water heating or heating support. They are intended to be used in conjunction with heat pumps and heating and heat pump regulators. The electric heating element can only be used in soft to medium hard drinking water up to 14 ° dH (hardness level 2). The electric heating element will fur up, overheat and fail if used in harder water. The electrical conductivity of the domestic hot water must be > 100 µS/cm and lie within the required drinking water quality.

LIMITATION OF USE

The electric heating element can only be used in soft

to medium hard drinking water up to 14 ° dH (hardness

level2). In harder water the life of the heating element

is shortened. The electric heating element will fur up,

overheat and fail.

NOTICE

Furring up of the electric heating element

reduces its heat output.

CAUTION!

The electrical conductivity of the

domestic hot water must be > 100 µS/cm

and lie within the required drinking water

quality. The sulphate and chlorine content

must not exceed 300 mg/l in total!

Disclaimer

The manufacturer is not liable for losses resulting from

any use of the unit which is not its intended use.

The manufacturer's liability also expires:

•

if work is carried out on the unit and its

components contrary to the instructions in this

operating manual.

•

if work is improperly carried out on the unit and

its components.

•

if work is carried out on the unit which is not

described in this operating manual, and this

work has not been explicitly approved by the

manufacturer in writing.

•

if the unit or components in the unit have been

altered, modied or removed without the explicit

written consent of the manufacturer.

•

if the electric heating element is furred up or if it

is damaged as a result of dry running.

We reserve the right to modify technical specifications without prior notice.

During installation and while carrying out

electrical work, comply with the relevant

EN-, VDE and/or local safety regulations.

Comply with technical connection

requirements of the responsible power

supply company (if required by the latter)!

The power supply for electric heating elements must be

equipped with a three-phase automatic circuit-breaker

with at least 3mm contact spacing to IEC 60947-2.

The electric heating element must be installed in a

horizontal position.

Adjustment instructions

The electric heating element contains an operating

thermostat (temperature controller) and a safety

temperature limiter.

The operating thermostat (temperature controller) can

be adjusted from approx. 15 °C– 80 °C.

The safety temperature limiter is set to a xed

temperature of 95 °C.

The safety temperature limiter trips

•

if the electric heating element is switched on dry.

•

the temperature level briey falls below the

operating thermostat (temperature sensor)

located in the middle of the electric heating

element.

•

if the operating thermostat (temperature

controller) fails and causes the medium

temperature to rise to >95 °C.

CAUTION!

If the safety temperature limiter has

tripped, the electric heating element

switches off automatically. If the safety

temperature limiter has tripped, the

electric heating element and/or the

system must be checked by qualied

personnel. The electric heating element

must be unlocked manually by qualied

personnel. This is done by pushing in the

release button.

CAUTION!

If the liquid level falls gradually (for

example, boiled away) the heating

elements are not protected by the

temperature limiter (parts of the heating

element dry, however, sensor tube is still

in liquid).

CAUTION!

Dry running can cause irreparable damage

to the electric heating element.

Setting symbols:

CAUTION!

If the heating element is set to a

temperature > 55 °C for domestic water

heating, there is a risk of scalding and

increased limescale precipitation.

CAUTION!

If the heating element is used for heating

support in a buffer tank, the temperature

must be set not higher than the ow

temperature calculated by your qualied

heating personnel.

If the temperature of the heating element

is set to a higher temperature, there is

a risk of overheating of the underoor

heating.

ENERGY SAVING TIP

Select the lowest possible temperature

setting.

The higher the temperature selected the

higher the energy costs.
