3. Installation
3.1 Foundation
Place concrete to build up the fl oor and discharge elbow foundations to the values shown in
installation drawing. The discharge elbow foundation must have suffi cient size and strength to
support the weight of the pump body, submersible motor and accessories plugs the weights of
the discharge pipe, and to absorb vibrations and impacts resulting from operation. Usually, it
should weigh more than seven times the pump weight.
3.2 Floor Frame (Fig. 1, 2 and 3)
Install a cable lead-out elbow and a fl oor frame on the fl oor over the pump pit. Attach a guide
pipe holder securely to the fl oor frame with bolts. As the guide pipe must be installed vertically
(with a tolerance of 1mm or less per 1m), carefully check the positional relationship between
the fl oor frame location and the discharge elbow foundation. (See Fig. 1 * )
If the guide pipe holder is attached directly to the concrete, use hole-in anchor bolt as shown
in Fig. 3.
CAUTION: IF THE CABLE LEAD-OUT ELBOW IS TOO SMALL IN DIAMETER, THE CABLE
MAY BE HEATED WHERE IT RUNS THROUGH THE ELBOW.
