Installation - FLOWTECH flowpac compact 1F.BD Operation And Maintenance Manual

Check, in the case of a preinstalled control box and of a single phase pump that the value of
the capacitor is according to the one stamped on the nameplate.
In case of anomalies or any doubt please immediately contact your supplier or service point signaling the
facts.
Never use the pump in case of doubts about its safety or its use.
Conditions of use
The following conditions must be observed when using the water pump:
•
Temperature of pumping liquid between: Min. +0°C – Max. +35°C
•
Max. depth: 70 mt
•
Voltage variation allowed: +/- 5%
•
Starts for hour: Max. 40
•
Minimum positive head level: 150mm
•
The pump is not suitable for pumping inflammable liquids or for operating in places with danger of
•
explosion.
The pump cannot be used in swimming pools or garden Ponds.
•

Installation

The installation is safety relevant, therefore it must be carried out by an expert and authorized installer.
CAUTION: during installation apply all the safety regulations issued by the competent authorities and
dictated by experience and common sense.
Make sure that the well is free from sand and other dirt, and that its dimensions are sufficient to fit the
•
pump.
Install a non-return valve on the delivery pipe to avoid the backflow of water.
•
Install an anti dry rotation system, (or check an already installed one)
•
The pump may be installed with either a metallic pipe (which can be used for sustaining the pump) or
•
with a flexible pipe. In the latter case use a stainless steel cable to sustain the pump. The cable should be
anchored in the hole on the discharge head of the pump.
• For no reason whatsoever lift or support the pump with the electric cable.
The pump should not touch the well bottom, keep it suspended (with the help of a support) at a height of at
least 150 mm.
Fasten the electric cable to the delivery pipe to prevent it from getting damaged. Do not pull the cable too
•
tight, so that the possible heat expansion of the pipe is compensated for.
Make the eventual extension or the cable exclusively with a suitable cable and with a rating according to
•
the necessary length as per our table in paragraph 10.
Extension junctions should only be made with a safe and waterproof system.
•
The ground cable connection must be physically separated from the power cable junction.
•
The pump (both single phase or three phase) should be installed with an electric switchboard
•
guaranteeing the following functions: overload protection, short circuit protection, anti dry rotation
protection.
We strongly request the installation of a around fault interrupter / RCCD-protector, whose current
•
differential operation must not exceed 30mA
For the connection of the single phase pump follow the wiring diagram shown in paragraph 9.
•
In case of a three phase pump check also the right sense of rotation. It should be clockwise for DIVER
•
and counterclockwise for DIVER HF looking the arrow on nameplate.
For no reason, even for only a few seconds, the pump can run dry (without water)
•
Be sure, before connecting the power, of the good insulation of the installation (min. 100 Mohm) and of a
•
correct ground connection.
The pumps DIVER and DIVER HF single phase versions equipped with a build in thermal overload
•
protector. It disconnects the pump when overheated and automatically starts it again once the
temperature has gone down to normal.
