III. INSTALLATION AND CAUTIONS
1. Make sure that the pipe system is securely connected before installation and
verify that the impurities, soldering leftover and wastes have been cleaned within
the pipes.
2. Make sure the pump is located in dry and ventilation environment to avoid short
circuit due to moisture or splashing into the casing, and guarantee, and guarantee
its availability to service and replacement.
3. The protection cover must be added; for the requirement of outdoor installation;
while actions must be taken to avoid being splashed and to prevent electric shock
risk in indoor installation.
Warning: do not install in bathroom to prevent vapor or water or moisture from
going into the junction box resulting in electric leakage.
4. When the pump is fully instaled, connect the power supply as pilot run and set
the speed adjusting switch at rated max grade to check if the starting is normal,
but the pilot running time can not be over 10 seconds so as to avoid idle running
influencing shelf lift of the bearing.
5. We strongly suggest you esteemed users to install shutoff valves at intake and
outlet ports for the< sake of following pump service and maintenance.
6. When the pump is supplying water to match the heat system, do not touch the
pump and/or other pipes to avoid burning.
7. The power plug must be strictly grounded. Securely connect the GND pin of the
power plug to the power plug grounded hole, Do not attempt to defeat the GND plug
of the pump.
8. The striking security caution markings must be set up during pump working to
avoid any accident.
9. The power supply must be firstly disconnected before adjusting pump localita-
tion or before any action that may touch the pump during the pump is working to
avoid any accident.
10. Regularly check the pump and timely replace in case of and damage.
11. Regularly check the insulating resistor of the pump, the insulating resistor in
cooled sate can not be lower than 50MΩ; and the insulating resistor can not be
lower than 2MΩ when it closes to working temperature.
12. The power cable can only be replaced with correponding cords or the dedicating
components.
13. In winter, when the environment temperature is below 0ºC, the water within the
pipes must be exhausted thoroughly if ht pump ceases working to avoid pump frost
crack.
14. The heat supply pipes can not be always compensated with non-soft water to
avoid the calcareous that water contained increasing even jam the impeller.
