Connect the delivery pipe/hose directly to the pump outlet. If the pump is used in fixed installations, it is advisable to connect it to the
piping by means of a coupling to facilitate disassembly and reinstallation. If a hose is used, fit a threaded hosetail to the pump outlet.
Wrap the thread with a suitable material to ensure an effective seal (Teflon tape or similar).
For fixed installations we recommend the use of the DSD lifting device (available on request - Fig.3) to facilitate maintenance operations
on the electric pump. Inserted between the delivery outlet of the electric pump and the piping, it avoids the disassembly of the delivery
pipe during maintenance operations. The DSD device consists of 7 parts, plus one not supplied (3/4" pipes):

The support foot should be placed on the bottom of the tank and secured with expansion screws to be sized appropriately.
The pipe guide bracket should be placed on the top of the trap and inserted at the end of two 3/4" pipes (not supplied), which act as a
chute. The two pipes connect the bracket to the support foot.
6. ELECTRICAL CONNECTION
Attention: always respect the safety regulations!
The single-phase motors are equipped with built-in thermal overload protection and can be connected directly to the mains.
N.B.: if the motor is overloaded it stops automatically. Once it has cooled it starts again automatically without requiring any
manual intervention.
Three-phase pumps must be protected with suitable motor protectors which are appropriately rated according to the data plate values
of the pump to be installed. The plug of the pump must be connected to an EC socket complete with isolating switch and fuses.
Do not damage or cut the power supply cable. If this should occur, have the repair or replacement carried out by specialised, qualified
personnel.
