1 HydroMixer direct distribution unit for heating systems 6 series REDITED LEI ISO 900 M 6 ISO 900 No / N unction The 6 series HydroMixer TM provides high temperature flow direct to secondary heating circuits, complete with onboard three-speed or variable-speed pump, supply and return temperature gauges, secondary circuit shut-off ball valves and pre-formed insulation shell. Versions are available with either the three-speed Grundfos UPS -8 pump or the variable-speed lpha -U pump. The unit can be ordered with supply flow and pump on the right or left side, and the unit is field reversible to accommodate changing installation requirements. The adjustable differential pressure by-pass valve, code 9600 and wall bracket code 600 are optional. The unit comes with male union connections which require separately purchased, inch sweat or HPT, top outlet or bottom inlet fitting kits.

If not acceptable, or field installation plans have changed, the position of the direction of flow can be switched. ollow the instructons below to switch sides as needed:. Remove insulation; front and rear shells. With UPS -8 pump the electronic housing of the pump must be removed by unscrewing the four screws indicated by the arrows and turning the body 90 counterclockwise and reinstalling. Without performing this task, it is not possible to push the group into the insulation. The LPH -U pump will fit inside the insulation without any modifications..reassemble the unit shown in the figure, tightening all union nut connections completely ensuring all seals are retained.. Reverse the position of temperature gauges as shown.. Unscrew the connecting pipes and shut-off ball valve/spacer assembly and remove the pump. 6. Move the spacer/insert square on the right. Note: you can use the recess channel in the center of the insulation for electrical cords.. Rotate the connecting pipe 80 relative to its axis. 7. Reassemble the insulation.
