phase of the pump and motor before
connecting the power source. Do not
run the pump if the voltage is not within
the limits.
All electrical connections must be in ac
cordance with the National Electric
Code. If there is a conflict between the
instructions provided and N.E.C. speci
fications, N.E.C. specifications shall
take precedence. All electrical equip
ment supplied with this pump was in
conformance with N.E.C. requirements
in effect on the date of manufacture.
Failure to follow applicable specifica
tions, or substitution of electrical parts
not supplied or approved by the man
ufacturer, can result in severe injury or
death.
Never install a positive shut‐off valve in the
discharge line; discharge restrictions will
cause excessive friction loss resulting in
overloading and destruction of pump and
drive components. It is strongly recom
mended that unless absolutely necessary,
no positive shut‐off valve be installed in the
suction line; excessive restriction will
cause incomplete filling of the diaphragm
chamber and result in shortened dia
phragm life.
