Commissioning the Heater
Re-assembly
Following tests must be carried out before com-
missioning the heater:
•
Insulation test with a voltage of at least 500V. The
dielectric resistance must be at least 0,5MOhm.
•
The electrical installer must measure the power
draw of the elements. This can be done using a
kW and time measurement or alternatively by
measuring the cold element resistance.
The value is to be compared with that of the rating
label or in the ‘Technical Data’ Section.
Note:
During the first charging periods the machine oils
various used in manufacture, as well as dust par-
ticles accumulated during manufacture and stor-
age burn off, causing an unpleasant odour.
Make certain the room is well ventilated.
Heaters that have already been in operation or have
been taken apart and repositioned must be re-
installed according to these instructions. The commis-
sioning tests described on this page must also be
carried out.
The first charging cycle after re-assembly must be
monitored by the installer until the charge control
switches off the elements.
Any insulation parts which are, or seem to be, dam-
aged or have changed properties which could influ-
ence their function and safety, must be replaced.
