install a circulating pump is recommended with a horizontal shaft.If you install the pump with vertical shaft (ie, the motor up) possible accumulation of air in it, which will prevent the bearing lubrication.Installation of the pump can be made both on the return pipe and the supply pipe of heating homes.Eliminate during installation possible mechanical stress!
Pick a place where you will install the pump.It is necessary to choose it, given that in the future access to the pump was not difficult.Install the pump after all the work on the system, so installing it should be the final step in the installation of the heating system.If the
heating system has been used, it must be thoroughly rinsed.
Cut the pipe where you plan to install the pump and weld it to the connection valves.Before the circulating pump and after the shut-off valve must be installed - it is necessary for easy removal of the pump for cleaning or repair.Provide as bleeding, if you want the pump to work long and reliably.
Weld the pump in the following order: check valves - Pump - Valves.When mounting observe the flow of water or other coolant, and directional arrows on the pump.After completing welding work, check the tightness of seams and fill the heating system coolant.
Connect the power cord to the pump.Electrical connection of the pump should be carried out taking into account all applicable technical standards and regulations.The minimum distance between the axes of the electrical contacts of the cable should be 3 mm, and the cross section is not less than 0.75 mm square.The cable must be equipped with a switch or plug.Turn on the cable outlet.
