4. MANAGEMENT
4.1 Storage
All the pumps must be stored in a dry covered place, with possible constant air humidity, free from vibrations and dust.
They are supplied in their original pack in which they must remain until the time of installation.
4.2 Transport
Avoid subjecting the products to needless impacts and collisions.
4.3 Weight and dimensions
The adhesive plate on the packaging indicates the total weight of the pump and its dimensions.
5. WARNINGS
-
The pumps must never be carried, lifted or allowed to operate suspended from the power cable; use the handle and cord
provided.
- The pump which does not stand on a base cannot support the weight of the pipes, which must be supported in some
other way.
The pump must never be allowed to run when dry.
•
The sealing device contains lubricant which is non-toxic but which may alter the characteristics of the water, in the case of pure water, if the
•
pump were to have any leaks.
6. INSTALLATION
Screw on the nipple with coupling supplied in the packaging, which is suitable for pipes with dimensions ¾'' and 1''; if you want to use a pipe with
a larger diameter, change the coupling. Use a pipe tightening clamp to secure the pipe to the fitting Fig.1
• It is advisable to use pipes having a minimum internal diameter of ¾'' mm, to avoid the decrease of pump performance.
To avoid obstruction of the suction passages, it is recommended to check periodically that no dirt has accumulated in the collection cistern
•
(leaves, sand, etc.). It is advisable to leave a minimum distance of 20 cm to avoid clogging of the suction grid (Fig.2).
• Insert the plug in a socket, main power must to be 230V.
the pump must be activated only if immersed in water. Consider a minimum submersion of 12 cm. If the water is finished the pump must be
•
stopped immediately, taking the plug out of the socket.
• The pump must be placed in a stable position inside a collection cistern or in the lowest part of the place where it is installed.
Ensure that the minimum dimensions of the collection cistern in which it is housed are as follows:
•
Min. base dimensions (mm) 150x150 / Min. height (mm) 800 Fig 2
• The dimensions of the cistern must always be in relation to the quantity of water arriving and to the flow of the pump, so as not to subject the
motor to excessive starts/hour; it is strongly recommended not to exceed 20 starts/hour.
The pump must be installed in vertical position!
7. ELECTRICAL CONNECTION
The length of the power cable on the pump limits the maximum depth of immersion in use of the pump. Follow the indications
on the technical data plate and in this manual, table 3.
8. START-UP
The electronics automatically control starting and stopping (ON/OFF) of the pump depending on the request for water by the user.
The electronics protects the pump against dry running conditions:
Priming cycle: When started, the pump will perform the following operation until it is primed: four priming trials of 30" (motor ON) with pauses of 3"
•
(motor OFF). If there is no water, i.e. if the priming trials fail, the pump will stop for an hour before trying to prime again. If also this trial fails, there will
be a 5 hours pause. Afterwards, if the lack of water persists, the pump will try to prime every 24 hours until it has picked up a prime.
• Normal Operation: If, during the pumps operation, the water supply is inferior to the minimum delivery for more than 40", the pump will go into
alarm, and start a priming cycle. In this case the priming trials are made after 1, 5, and 24 hours until the pump picks up a prime.
The electronic unit also protects the pump from damages that could be caused by the blocking of the Not Return Valve (NRV). Such blockings
are generally due to dirt deposits, or sand and they cause the pump to operate also if there is no water demand from the end-user. The protection
function stops the pump automatically every hour; if no damage is detected the pump re-starts immediately. If the VNR is blocked the pump goes
into alarm and stops. In this case the pump can be re-started only after unplugging the pump and removing the obstruction to the VNR.
Flow control:
The flow control deactivates the pump if no water is drawn. If there are leaks on the pressure side (e.g. water tap or hose not watertight), the pump
starts and stops at short intervals. If the pump starts and stops more than 7 times in 2 minutes (in case of a leak < 6 l /h), it will switch off completely.
Once the leak on the pressure side has been eliminated, switch the pump off and on so that it can be used again.
The best working condition is with the pump be completely submersed in water.
Anyway the motor's cooling system allows the use at the minimum suction height for very short periods.
The pump is equipped with a stainless steel anti-deposit filter.
