Crane WEINMAN WE411, Installation And Operation Manual

Stainless Rail Package (Not Shown)-

 The package system

comes complete and ready to place into the ground as outlined
in the project specifications. The moveable portion of the Slide
Away Fitting (SAF), check valve, piping and guide bracket
comes assembled on the pump along with the lifting cable.
Insert pump bracket and moveable portion of SAF into the
guide channel and lower pump into basin 

(DO NOT DROP).

Now connect power and control cables to the junction box or
control panel depending on system design. 

C-3)  Liquid Level Controls

Figure 2 shows a typical installation for any submersible pump
using a level control mounted to the discharge piping with a
piggy-back plug.

General Comments:

1) Never work in the sump with the power on.

2) Level controls are factory set for a pumping differential of 9
inches. If that is the cycle desired, simply circle the discharge
pipe with the pipe mounting strap, feed the end through the
worm drive, and tighten with a screwdriver. Be certain that the
level control cannot hang up or foul in it’s swing. Also, make
certain the pump impeller is still submerged when the level
control is in the ’off’ mode.

3) If a higher pump differential is needed, grip the cord near the
neck of the float, then using the other hand, exert a steady force
on the lower edge of the cable clamp. The cable clamp should
slide up to the new pivot point. Attach the level control to the
discharge hose in the manner described above.

4) Plug the level control plug into the receptacle, then plug the
pump into the piggyback plug. One cycle of operation should
be observed , so that any potential problems can be corrected.

5) It is recommended that the float should be set to insure that
the sump well liquid level never drops below the top of the motor
housing or a minimum level of 6" above the pump bottom.

6.) Figure 3 shows a typical connection for pumps with the wide
angle float and piggy-back plug. for manual and automatic
operations.

Automatic- 

Plug float cord into outlet, then plug
pump cord into float cord.

Manual- 

Plug pump cord directly into outlet.

C-4) Electrical Connections:

WARNING ! - All model pumps and control panels
must be properly grounded per THE NATIONAL

ELECTRIC CODE and YOUR LOCAL ELECTRIC CODE.
Improper grounding voids warranty.

C-4.1) Power Cable:

The cord assembly mounted to the pump must not be modified
in any way except for shortening to a specific application. Any
splice between the pump and the control panel must be made
in accordance with the National Electric Code and all applicable
electric codes. It is recommended that a junction box, if used,
be mounted outside the sump or be of at least NEMA 4
construction if located within the wet well. 

Do not use the

power cable to lift pump.

NOTE:

 The white wire is 

NOT

 a

neutral or ground lead, but a power carrying conductor.
