Setting minimum limitation Mounting and installation notes Important: 3 3 3 4 4 2111Z36 4 When mounting the actuator to the valve, ensure that valve and actuator form a right angle. 5 For that, select scale number 5 and ensure that the actuator rests correctly. Acvatix TM 2111Z38 RTN5 1 Then, tighten the actuator correctly. 4 2111Z35 2111Z34 3 The sensing element of the thermostatic actuator must always be able to acquire the temperature of circulating room air.

2143Z02 2111Z03 The actuator must not be fitted in the upright position to ensure that measurement of the room air will not be affected by rising air from the hot water pipe. Mounting Instructions are printed on the package. RTN71 Version with remote sensing element and capillary tube This type of actuator is for use on applications where the criteria of the RTN51.. standard versions are not satisfied. This actuator can be fitted in any position.

Repair The actuators, sensors and remote adjusters cannot be repaired. The complete units must be replaced. Disposal The device must not be disposed of together with domestic waste. Legislation may demand special handling of certain components, or it may be sensible from an ecological point of view. Current local legislation must be observed. Warranty Application-related technical data are only warranted when used in connection with the valves listed under "Equipment combinations" (page 2).
