Electrical Preparation
Terminal Box Position
At the bottom of the stator, closest to the pump housing, there are two drain holes to allow
condensed water to escape. The drain holes must point downwards. As they are opposite the
terminal box position, the terminal box must point upwards in one of the positions shown in
Fig.l. The following terminal box

Rotating the Terminal Box
To rotate the terminal box, follow these steps:
WARNING:
Ifthe pump is already installed in the system, the system must be drained

vented.
AVERTISSEMENT:
Si la pompe est deja installee, il faut drainer Ie systeme ou fermer les deux
robinets d'isolement lateraux de fa pompe avant d'enlever les vis a tete hexagonale, car Ie Iiquide
pompe pourrait etre brOlant et/ou sous pression. Ne pas faire fonctionner la pompe jusqu'a ce
que Ie systeme ait ete rempli de Iiquide et purge.
1.
Remove the four allen 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 a-ring
is properly seated in the pump housing.
3.
Replace the pump head onto the pump housing
4.
Tighten the allen head screws evenly. Torque to:
8mm
15
ft Ibs
lOmm
25 ft Ibs
S.
Check to make sure the rotor turns freely. Do this by removing the 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 1-4 above.
6.
The position of the nameplate can be changed by easing the outer edge of the plate
at the cut out with a screwdriver. Turn the nameplate to the required position and
push into place.
7.
Refer to page 15 for additional instructions.
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
sytem, where air accumulates.
