minal posts as shown in Figure E-5. Remove any
adhesive from gasketed surfaces.
All air pockets, voids or gaps in the sili­
cone sealant must be removed to en­
sure a water‐tight seal in the terminal
housing. Otherwise, moisture entering
the terminal housing could cause a
short circuit, resulting in pump damage
and possible serious injury or death to
personnel.
Allow the adhesive to cure for at least one hour be­
fore securing the terminal housing to the motor
housing.

Sealing Terminal Plate Connections
With Potting Compound
(Figure E-2)
Potting compound and silicone adhesive have the
same electrical properties when correctly applied.
Silicone adhesive is used at the factory to facilitate
production. A commercially available potting kit
(Products Research Corp., part number
PR‐1201‐Q Class 1 potting compound, Chemseal
potting compound, part number GS3100, or equiv­
alent) may also be used to seal the connections.
Clean and assemble all terminal components as
indicated in Sealing Terminal Plate With Silicone
Adhesive. Use medium grit sandpaper to prepare
the surface of the terminal plate in the area where
the potting mold will be installed.
NOTE
Clean the cable lead and terminal plate in the areas
to be potted with cleaning solvent before potting.
Potting compound will not adhere properly to oil or
grease coated surfaces.
Trim the potting mold so it is just long enough to
cover the terminal collars (or use the adhesive res­
ervoir). Slide the potting mold up over the leads of
the power cable and control cable.
Secure each cable lead as described in the pre­
vious section. Slide the potting mold down over the
terminal collars and onto the terminal plate. Hang
the cable in a vertical position with the terminal
plate horizontal. The cable leads and terminals
should be centered in the potting mold. Use quick‐
setting cement, such as `3‐M Weather Seal' to se­
cure the potting mold to the terminal plate.
Most potting base compounds contain
toluene; use adequate ventilation and
avoid prolonged breathing of vapors.
Most potting accelerators contain lead;
