Electrically actuated 3-way valve:
Electrically actuated 3-way valves of the relevant sizes are used in chiller systems with up to 36,000 BTU.
The selection is made according to the diameter of the pipe used.
3-way valve 5/8" incl. fitting
3-way valve 3/4" incl. fitting
3-way valve 1" incl. fitting
The hoses must be installed without kinks and (to ensure perfect bleeding) rising if possible. Hose connections must be
supported by hose clips to prevent them slipping.
NOTE: The hose clips must be tightened with a torque value of 35 lb-in. (4 Nm).
The cooling system must be bled carefully before using the heater for the first time or after
replacing the water. The heater and lines should be installed in such a way as to ensure static
bleeding. Perfect ventilation can be identified by the circulating pump operating almost silently.
Poor bleeding may cause the resetting temperature limiter to trip while the heater is operating.
