Rotating the terminal box
To rotate the terminal box, follow these steps:
WARNING
If the pump is already installed in the
system, the system must be drained
or the isolation valves on both sides
of the pump must be closed before
the hex socket head screws are
removed as the pumped liquid may be
scalding hot and/or under pressure.
Do not start the pump until the system
has been filled with liquid and vented.
1. Remove the four hex socket head screws
holding the pump head onto the pump
housing.
2. Carefully lift the pump head and rotate it so
the terminal box is in the desired position.
DO NOT locate the terminal box beneath the
pump. Make sure the O-ring is properly
seated in the pump housing.
3. Replace the pump head onto the pump
housing.
4. Tighten the hex socket head screws evenly.
Torque to:
8 mm............15 ft lbs
10 mm..........25 ft lbs.
5. Check to make sure the rotor turns freely.
Do this by removing the vent plug in the
middle of the pump nameplate. Insert a
medium size flat-blade screwdriver into the
slot at the exposed end of the shaft.
Gently turn the shaft. If it does not turn
easily, repeat steps 1 to 4 above.
6. The position of the nameplate can be
changed by easing the outer edge of the
plate at the cutout with a screwdriver.
Turn the nameplate to the required position
and push into place.
7. Refer to pages 11 and 12 for additional
instructions.
4.2 Piping considerations
Thoroughly clean and flush all dirt and sediment
from the system before attempting to install the
pump.
Location in the piping line
The pump should never be located at the lowest
point of the piping system, where dirt and
sediment collect. Nor should it be located at the
highest point of the piping system, where air
accumulates.
Mounting positions
The arrows on the flanges of the pump indicate
the direction of water flow. Although the
UP Series 200 may be installed in either vertical
or horizontal piping, the motor shaft must always
remain horizontal, as shown in figures
Fig. 2
Direction of water flow through the
pump
Pumps installed outdoors must be
protected by a ventilated, watertight
Note
cover to keep out moisture and dirt.
WARNING
The pump must be positioned so that
no one can accidentally come into
contact with the hot surfaces of the
pump.
4.3 Connect the pump
Install the pump into the piping system.
Grundfos recommends that pressure gauges be
installed in the inlet and discharge flanges or
pipes to check pump and system performance.
