Building up the pump
unit
APP pump instruction APP 0.6-1.0, APP 1.5-2.5 and APP 3.0-3.5
Automatic pressure equalization between tank
and surroundings must be ensured.
Inlet from the water supply and inlet to the
pump should be placed in opposite ends of the
tank to calm and deaerate the water, and to
ensure optimum opportunity for particles to
settle.
Pump suction line should be placed relatively
high above the tank bottom in order to prevent
settled particles from being led into the pump.
We recommend a separation ("wall") to separate
the inlet from the outlet end of the tank.
Monitoring
It is recommended to continuously monitor the
following conditions:
•
Water level in the tank
•
Filter contamination
•
Pressure (inlet- and outlet side of the
pump)
3.1 Mounting
(Please also see hints in "Right and Wrong")
If alternative mounting is desired, please contact
the Danfoss Sales Organization.
Choose proper tolerances to ensure an easy
mounting of the elastic coupling without use of
tools.
Please take care to observe the recommended
length tolerances of the chosen coupling, as an
axial force on the pump will damage the pump.
3.2 Direction of rotation
Is indicated by means of an arrow at the inlet side
of the pump.
