Notes
Installation Instructions are enclosed in the package.
It must be ensured that there is sufficient clearance above the thermostat for seeing
through the viewing window, for adjusting the switch-off temperature, (e.g. type RAK-
ST.1300P-M) and for removing and replacing the thermostat, if required.
The clamping band should be properly tightened to ensure the entire length of the
sensing element is in close contact with the pipe’s surface.
Mount the pocket and adjust the hexagon as required. Immerse the capillary sensing
element in the pocket and secure the base to the pocket by means of the screw.
To prepare for wall mounting, knock out the fixing holes in the housing and pull out the
capillary tube until the required length is reached. After immersing the capillary sensing
element in the pocket, secure it with a clamp (mounting accessories).
The switch-off temperature (40…70 °C or 95..130 °C) must be adjusted by qualified
personnel.
The appliance must be wired by the installer only. The cables used must meet the
insulation requirements for mains voltage.
In case of rupture of the capillary tube, contact 11-12 will open (fail-safe function).
Wire the thermostat according to the connection diagram and in compliance with local
regulations.
Caution: prior to opening the housing, disconnect the thermostat from the mains supply.
Earth connections must be made in compliance with the regulations.
