Checking the electrical installation

Notes:
- The standard settings (see preceding table) refer to a water hardness of 210 ppm
(12 °dH or 21 °fH, respectively). When using E-water (softened water) the
switch must be set to the next lower position (example: if the standard setting is
5 you may set the switch to 4 for operation with E-water).
- If the Defensor Mk4 is operated with VE-water (demineralized), the switch can
be set to "0".
- All interval times specified are theoretical values. They may differ in practice from
these values owing to tolerances in the inlet valve, level unit, mains voltage, etc.
The interval times refer to a steam output of 100 %. If less output is required in
operation, the interval time is correspondingly increased.
- The flushing interval time is limited to 5 hours. After this time automatic flushing
takes place with float test (independent of the interval time set).
Correct installation should be checked using the following check-list:
- Do the data on the nameplate for the power and control unit correspond with
the relevant mains voltages?
- Are the supply voltages (power unit and control unit) correctly protected with
fuses?
- Is the service switch "Q" fitted in the supply to the power unit and the control unit?
- Are all components correctly connected according to the connection diagram?
- Are all connecting cables secured?
- Is the tension relieved in the connecting cables (taken through compression
glands, secured with clamping holders)?
- Is the rotary switch "SW2" set according to the controller connected (active/
passive)?
- Is the bottom access door of the basic case raised and locked?
