B-4.4) Direct Burial Cable with Conduit Coupling
(Combination Cover):
Backfill and compact to a convenient level to work around
top of basin. To install an
OPTIONAL
conduit coupling (see
Figure 10 & 11).
1. Feed the cables up through the appropriate holes on
the new insert.
•
The holes are labeled "DB" (Direct Burial Cable),
"PP" (Pump Power), "PC" (Pump Control - SGV Units Only)
and "LC" (Level Control).
•
Make sure at this point, that all of the cables will be long
enough to reach their connection points in the panel while
still having enough room to remove the insert from
the basin.
2. Looking at the color-coded diagram on the lable
attached to the panel, slide the appropriate color-coded
friction ring, color-coded gromment, second color-coded
friction ring and gland nut over the cable. Loosely thread
the gland nut into the gland molded into the insert so that
the cable will still move in the assembly.
3. Feed the cord through the appropriate cord grip on the
control panel making sure that the rubber grommet is
installed in the grip.
•
The cable jacket should be visible from inside the control
panel to insure that the grommet is not sealing on individual
wire strands.
•
Care should be taken to make sure there are no slits or
damage on the cable jacket where the cord grip is sealing.
4. Tighten the control panel grips to 1/4 turn past hand tight
using a pair of channel locks. After tightening the grip,
make sure the retaining nut for the grip on the inside of
the panel is tight.
5. Tighten the gland nuts per the instructions on the
control panel label (3 turns past finger tight).
6. Reference the Control Panel manual for panel wiring
details.
After the coupling has been installed, run the direct burial cable
through the coupling and into the grommet labeled "DB" in the
insert. Reference the lable on top of the control panel to locate
the correct grip in the control panel to put the wire into.
Leave
enough cable inside the panel to reach all connection
points. Tighten the grips leaving enough slack between
the basin wall and the insert to remove the insert completel
off the basin.
B-5) Backfill:
Finish backfill and compaction. (see Figure 12). Place at least
4 inches and preferably 6 inches of aggregate in layers around
the entire periphery of the basin in the ground, being careful
not to damage or loosen any connections.
CAUTION !
IN FREEZING CONDITIONS BACKFILL MUST BE DRY
AND FREE OF ICE.
DO NOT
use backfill materials other than those specified
above. In areas where specified materials are not available
contact Barnes Pumps, Inc. for information on approved
alternate materials.
The basin warranty is automatically voided if other than
approved bed and backfill materials are employed without
advance written approval.
B-6) PUMP INSTALLATION:
First attach lifting rope or chain to the pump (See Figure 13).
Remove basin cover or open access door. Record Pump
Model, Part and Serial numbers in Start-Up manual and on
User Guide. Rotate pump impeller by hand and then lower
pump and movable assembly, utilizing the lifting chain or rope,
down the rail slowly,
(DO NOT DROP)!
Observe OSHA
recommendations when installing and removing pump.
CAUTION !
RISK OF ELECTRICAL SHOCK. DO NOT LOWER PUMP
BY THE POWER CORD.
