Generator Sizing; Operation - Craftsman 390.2655 Owner's Manual

Grounding Outlet
If your outlet is not grounded, install a copper wire, at least
14 gauge (2mmZ), from the outlet box, as shown in Figure
B, to a metal cold water pipe. Use ground clamp on pipe.
IMPORTANT: The cold water pipe you use as a ground
must have metal continuity to electrical ground. If continuity
is interrupted by plastic, rubber, or other electrical insula-
tors; such as hoses, fittings, washers or gaskets (including
water meter or pump), a metal bypass must be used. Any
electrically insulated connector should be jumped (as shown
in Figure C), with a length of No. 4 wire clamped securely
at both ends.
Automatic Thermal Overload Protection
This pump motor has a built-'m automatic thermal overload
protector. If the motor overheats, the protector wiU open
and cut off power to the motor before the heat damages it
internally. The overload will reset automatically and the
pump will restart after the pump cools down below the dan-
ger point.
[ AWARNING ]DO NOT attempt to work on the pump or
motor if the overload seems to have tripped. The
motor may restart without warning at any time. You
could be injured and the pump damaged ff it starts
when you are working on it.
DO NOT attempt to repair a non-operational pump. Take it
to Sears for service by a qualified technician.
Generator Sizing
Below is the minimum Engine-Generator Watt rating re-
quired to power this pump motor. Any additional loads,
such as lights, must be added to the listed load and the gen-
erator sized accordingly.

OPERATION
[a_'WARNINGJRJsk of electric
shock. Do not handle
pump or pump motor with wet hands or when stand-
hag on wet or damp surface, or in water.
NOTICE: Do not use this pump in ponds containing plants
or fish.
1. Shaft seal depends on water for lubrication. Do not oper-
ate pump unless it is in at ]east 3/16" (4.75mm) of water
as seal may be damaged if allowed to run dry.
2. Motor is equipped with automatic reset thermal pro-
tector. If temperautre in motor should rise unduly, switch
v_tll cut off all power before damage can be done to
motor. When motor has cooled sufficiently, switch will
reset automatically and restart motor. If protector trips re-
peatedly, pump should be checked as to cause of diffi-
culty. Low voltage, long extension cords, clogged
impeller, very low head or liR, etc., could cause cycling.
3. Pump w'dl pump water down to 3/16" (4.75mm); this
means that it v_ill not remove all water. If unit has been
operating and suddenly no water comes out of discharge
hose, shut off unit immediately. Water level is probably
very low and unit has broken prime. Use mop or
squeegee to remove remaining water.
[AWARNING 1 Risk of electric shock. Before attempt-
ing to check why unit has stopped operating, dis-
connect power fi'om unit. Do not handle pump with
wet hands or when standing on wet or damp sur-
faces, or in water. Failure to follow precaution can
result in personal injury and/or property damage.
Airlocks
When a pump airlocks, it rims but does not move any water.
An airlock wiU cause the pump to overheat and fail. This
pump has an anti-airlock hole in the bottom of the pump
body" (see Page 7). If you suspect an airlock, unplug the
pump, clean out the anti-aiflock hole with a paper clip or
piece of wire, and restart pump.
IMPORTANT: This hole allows the pump to start priming
wir21in 15 seconds in as little as 1/2" of water. NEWER restart
pump in less than 1/2" of water. Leakage from the anti-air-
lock hole is normal.
