DN20 installation:
1. Cut the power supply before installation and must be installed by professionals.
2, the flow direction should be the same as the direction arrow on the valve body.
3. The valve should be located above the fan's water pan to ensure that water droplets fall into the water pan.
4, the valve and controller must be installed within ± 60 ° in vertical direction, and there should be at least 30mm clearance above for disassembly.
5. The space must be sufficient from pipes, devices and surrounding buildings for maintenance operation, and make sure the place is accessible by maintenance personnel through the sewer.
6. Two or more valves cannot be connected in parallel. If parallel connection is really necessary, use relay for isolation.
7. Install the valve first and test the pressure with the tubing, then install the controller.
8. If the controller is already installed on the valve, do not apply force to the controller during installation and debugging, otherwise it will damage the controller.
9. The unit cannot be wrapped with thermal insulation material, otherwise it will affect its heat dissipation.
10. The conductor must be grounded with no less than 1.5mm & sup; 2 ;, other cables must be in accordance with the relevant standards of the electrician.
11. After installation and make sure everything is correct, turn on and debug without water. Observe three complete unit operations at least until all parts are normal and correct.
12. No Water after adjustment, then scrub with water. The pressure difference of the water variation in the system must be strictly controlled within 0.13MPa, to ensure the efficiency of the valve to the water flow switch.
