Mounting MASCONTROL pump controller (see Figure 1):
The MASCONTROL may be mounted directly on the booster pump's outlet.
MASCONTROL must be mounted on a vertical column with the
electronic box level, and the flow direction arrows pointing upward.
Use only Teflon tape for threaded connections.
Do not install any tap between the pump and the MASCONTROL.

INSTALLATION
ATTENTION: Apply all safety rules dictated by professional standards.
WARNING: Disconnect power before installing system.
Conduit Connections:
BEFORE MOUNTING THE MASCONTROL pump controller on
the booster pump, open the MASCONTROL's electronic box
cover by removing the six screws (refer to the MASCONTROL
manual packaged with the pump controller). Press the two rubber
grommets (supplied) into the 1/2" conduit connection holes located
on the side of MASCONTROL's electronic box. A flat blade screw-
driver may be needed to help insert the grommets. "Liquid-tight"
non-metallic conduit fittings rated "NEMA 12" or "UL type 12" can
be used (not supplied) to achieve NEMA type 12 enclosure rating.
Use of metallic conduit is not recommended.
