2.1.2 Care should be used in loading and unloading this unit to prevent any
unnecessary shock to the components.
2.1.3 Caution:
When lifting, always use a four point lift to protect unit from
damage and/or turning upside down during lift.
2.2 Centrifuge Mounting
The 414 Centrifuge must be mounted above the ground to facilitate solids removal.
For recovery of weight material the solids discharge outlet should be located over a
well stirred area of the mixing pit. A slide attached from the solids outlet may be
necessary to route solids to the mixing pit. The slide should be set at a steep angle to
prevent a solids buildup.
The Centrifuge unit must be set level and on adequate supports. It may be necessary
to attach it to the support by tack welding.
2.3 Electrical Installation
2.3.1 The electrical installation should be made by a qualified electrician. Input
power fusing must be current limiting type. See Wiring Schematic, Diagram
12 for sizing.
2.3.2 Feed Pump - Control circuit power is taken from terminals TB1 and TB2 in
the main control box (Item 216, Diagram 11) for the feed pump starter. This
requires running a 14 gauge 2 conductor approved wire from the main control
box to the feed pump starter. For typical hookup see Diagram 15. Pump
starter holding coil must be 120 volts. Power for pump may come from any
source of sufficient amperage and proper voltage. If feed pump auto shut
down feature is not desired, starter may be used as wired and power cable
hooked to any source of proper voltage and sufficient amperage.
2.4 Feed Pump
2.4.1 Any pump capable of furnishing the feed rate desired at sufficient pressure to
overcome line loss may be used to feed the 414 Centrifuge.
2.4.2 A 5 Hp variable speed progressive cavity pump which furnishes 22 gallons
per 100 revolutions is available from Swaco and is ideal for feed between 40
and 80 gpm's. (Swaco Type II Pumping Unit)
