1 PRODUCT TECHNICAL SPECIFICATION

The screw-mounted electrical heating unit (heating unit) is designed exclusively for water heating. It is

designed as an additional heating source in water heaters connected in a system with solar collectors. It can

also be used as an additional source of heating in accumulation tanks. If the installation requirements are

obeyed, it can be used as the main source of heating by a heater, or for other purposes. It is not intended

for use in stainless tanks. Types with extended cooling compartment can be used in accumulation tanks

marked with v6 and v7.

Water is heated by tubular heating element. Thermowell contains sensors of a safety fuse and a thermostat

(both devices are in a single block). The thermostat controls the set temperature of water. In case of

a failure, the safety fuse switches off electricity supply in all poles within the temperature range of 0 – 90°C.

Prior to putting the heating element into operation, re-measuring of insulation resistance

is recommended. The insulation resistance in cold must not be below 50 MΩ. If the

insulation resistance is lower, we recommend drying the heating element.

Both electric and water installation must follow and meet requirements and regulations

relevant in the country of use.

The heating unit consists of an electrical heating element with a connecting thread G 6/4".(Figure 2)

A thermostat and a safety fuse; the element's operation control light; and a connecting terminal board are

placed under the wiring plastic cover Chyba! Nenalezen zdroj odkazů. To use the OKC ... NTR, NTRR, OKCE
