Thermostatic mixing valve for water heating.
Design
Valve body made in DZR-brass, EN 12165 CW602N.
Warm water within the range 38°C-65°C.
- Max pressure: 1,0 MPa
- Max working temp: 90°C
Fitting / Installation
The arrow on the valve housing indicates the direction of the flow.
KV = incoming cold water
VV = incoming hot water
BV = outgoing warm water
The valve has compression fittings for fitting to copper or steel pipes.
When fitted to a male thread connection, adapter LK 373 15 x G½ art.no 189 8022 (550-15) alt. adapter LK 373 22 x G¾, art.no 189 8055 (550-22 & 545-22) is used.
It is easier to fit the compression fitting if a lubricant is applied to the thread and bevel. Tighten first by hand and then with a box spanner. Soft pipes are to be fitted with a support sleeve.
Operation and maintenance
The mixing valve requires no maintenance. The installation should be checked regularly.
The valve knob is used to set the desired hot water temperature within the range 38°C to 65°C. The maximum temperature can be calibrated as follows:
Increasing the maximum temperature:
Turn the knob counter-clockwise to (+). Loosen the screw and move the knob out to the side. Then turn the knob clockwise to (-) without it being engaged. Adjustments are carried out in small steps. A ¼ turn corresponds to approximately 7°C. Reinstall the knob and check that it engages with the "teeth". Tighten the screw and then turn the knob to max (+).
Max calibration for increasing the temperature is a ½ turn.
Reducing the maximum temperature:
Do the procedure in reverse. Turn the knob clockwise to (-) and the disengaged knob counter-clockwise to (+).
