GENERAL SAFETY INFORMATION
(FOR 12 VDC UNITS ONLY)
1. General connection information to a 12 VDC battery:
a.
Connect POSITIVE or PLUS(+) lead from the pump to battery first.
POSITIVE lead of pump is red.
b. Connect NEGATIVE or MINUS(-) lead last. NEGATIVE lead of pump
is black.
c. When DISCONNECTING – Disconnect NEGATIVE (-) lead first,
then disconnect the POSITIVE (+) lead from the battery.
2.
Specific connection information
:
a. If pump is installed in car or truck and the installed car or truck
battery is being used:
(1) Connect POSITIVE or PLUS (+) lead from the pump to battery
first. POSITIVE lead of pump is red.
(2) Then connect NEGATIVE or MINUS (-) lead to a ground away
from the battery, such as the metal of the car. Always connect
NEGATIVE (-) last. NEGATIVE lead of pump is black.
(3) When DISCONNECTING – Disconnect the NEGATIVE (-) lead
from the grounded location, then disconnect the POSITIVE (+)
lead from the battery.
b. Pump is installed in recreational vehicle (RV), boat, motor home, etc.
(1) Follow general connection information.
(2) If possible, connect NEGATIVE (-) lead of the pump to negative
wiring terminal strip or other negative common point of the
battery (away from the battery) if so equipped.
3. When attaching pump leads to battery terminals, be sure that the area
(bilge of a boat, for instance) is adequately ventilated to prevent an
explosion or fire from explosive or flammable vapors that may be present.
Batteries emit hydrogen gas which is explosive. Avoid smoking, sparks
or open flame anywhere in the vicinity of the battery.
Explosion from battery can cause blindness. Shield eyes when working
near
any battery.
Batteries contain sulfuric acid. In case of contact with eyes, skin or
clothing,
flush immediately with large amount of water, get medical
attention.
4. When using leads longer than those supplied, be sure the wire is
adequately sized.
Do not add acid or electrolyte to battery being used – add only water.
Consult the battery manufacturers for any additional safety instructions.
INSTALLATION (FOR 12 VDC UNITS ONLY)
WIRING & ROTATION
Connect black wire to NEGATIVE (-) terminal of battery. The orange wire with
the fuse holder should run to an overload protected switch or circuit breaker,
with a wire from switch or breaker to POSITIVE (+) terminal of battery. Electrical
circuit must be independent of all other accessories. To prolong motor life,
install pump so normal motor rotation is clockwise (See Figure 1). Use proper
wire size as determined by Wire Table (See Figure 1). The proper fuse has
been included in the fuse holder. Should this fuse blow, replace with the same
size fuse after determining reason for blown fuse.
NOTE:
No warranty consideration will be given to pumps that are returned
without the properly sized fuse and fuse holder supplied with the pump.
DESCRIPTION
This compact utility pump is designed for a wide range of dewatering and liquid transfer applications including marine and aquaculture. Handles liquids from 40° F
to 180° F (4º to 82º C). This is a manual unit, no controls are supplied. For use with nonflammable, non-abrasive liquids compatible with pump component ma
-
terials.
These pumps self-prime (to 4-1/2 ft. lift with pump filled) and can be used as a bilge pump for small boats or a water system pump in campers and trailers. The
pump can be mounted up to a 45° angle or on a thru-hull fitting and seacock for applications requiring water aboard to be pumped overboard.
