3) Fully open the valve and flush it out with the maximum flow rate.
When fluid flows for the first time, it is to clean out the foreign substances and refuse in the pipes.
The valve is set to fully open when it is shipped from the factory.
CAUTION
After installation, make sure no fluid leaks from the valve-pipe connections.
Improper piping may cause fluid leakage outside of the valve.
Do not put a load or weight on this product.
Doing so may damage the product.
Heat insulating
Apply heat insulation as illustrated by
in Fig. 6.
If the yoke and/or the actuator are covered with insulation material, the point cannot be checked or may be distorted.
If the heat insulation is inappropriate, accuracy of flow rate measurement and temperature measurement may degrade.
When cutting the insulation material that covers the valve, be sure not to damage the valve sensor cable.
