INSTALLATION
MOUNTING
Mount upright in a dry location (above highest bilge
water level) on a solid surface. Selection of a dry, cool,
ventilated location will generally extend pump life. Locate
Pumpgard strainer in accessible spot in suction hose.
PLUMBING
For intake and discharge use 3/4” ID non-collapsible
hose. Keep intake and discharge line free of kinks and
restrictions. To protect pump from debris, use the 3/4” in-line
strainer, Model 36200-0000 in the intake line from the bilge.
WIRING
Wire pump in a circuit independent of all other electrical
fixtures. Use stranded copper wire. Install fuse in posi-
tive circuit. See table for recommended wire and fuse
size. See diagram for wiring instructions. Use a 10 amp-
rated switch (44960-Series). After installation, it is rec-
ommended that voltage be checked at the motor termi-
nals with motor operating under full load. Voltage should
not be less than 90% of rated motor voitage.

WINTER STORAGE
When possible it is preferred that the complete pump be
removed and stored in a warm dry place. If this is not
possible the pump must be completely drained, hoses
removed and pump run until all water is expelled.
