BOX - Translation of the original instructions
4.9 Check valve
It is recommended that a check valve is installed on the discharge pipe connected to the sewer system to prevent backflow of the water column
into the lifting station.
Some versions of blueBox are equipped with a check valve installed directly on the coupling device.
If the model purchased is not fitted with a check valve, it is recommended that an external ball-type check valve is installed.
4.10 Shut-off valve
A shut-off valve must be installed on the discharge pipe to secure maintenance operations to ensure safety during maintenance operations.
It is recommended that a shut-off valve is also installed on the inlet pipe.
Gate valves or ball valves can be used for this purpose.
4.11 Float stroke limiter (for Zenit pumps, blue series)
A special accessory allows the stroke amplitude of the float switch to be changed if the pump start level is too close to
the alarm level.
Installation procedure (see Annex 7)
1. Pull the float switch cable out of the eyelet cable tie on the handle.
2. Introduce the stroke limiter into the eyelet cable tie of the handle.
3. Lock the float cable in the eyelet cable tie of the stroke limiter. Leave about 100 mm of free cable required for operation.
4. Secure the stroke limiter to the handle using the cable tie provided.
5. Secure the float cable to the stroke limiter using a cable tie placed in the slots provided.
4.12 Maximum level alarm float
The maximum level alarm float indicates if the level of the liquid is too high inside the tank as a result of pump failure
or if there is an excessive amount of effluent entering the tank.
The maximum level float is optional for blueBOX 60, 90, 150
standard
and is supplied as standard for 150
full optional
,
250 and 500 models.
It must be connected to an electrical control panel set up with an audible and/or visual alarm.
4.13 Level sensor 4-20 mA
An optional level sensor with a standard 4-20 mA output can be used for starting and stopping the pump instead of a
mechanical float switch.
The level sensor must be connected to a pre-arranged electrical control panel.
It is recommended that an electrical control panel equipped with a backup battery is used in order to ensure proper
operation of the level sensor even in the event of a power failure.
4.14 Cable glands
The blueBOX allows the application of 4 cable glands for models 60, 90, 150 and 250 and up to 8 cable glands for model 500 for the electrical
cables from the lifting station.
Installation procedure (see Annex 8)
1. Drill a hole in the tank at the pre-arranged point for the installation of the cable gland with a suitable size drill bit
according to the diameter of the cable gland.
2. Correctly place the cable gland in the hole and secure it with the nut.
3. Insert the gasket into the cable gland and screw on the ring nut without tightening it.
4. Once the cable exits on the outside, tighten the ring nut to secure the cable.
4.15 Electrical connection
Electrical connections must be made by qualified personnel.
Power outlets or the electrical control panel (where applicable) should be located in a dry place, at a safe height in case of flooding.
For the electrical connection of pumps and electrical control panels, follow the instructions in the relevant manuals.
caution!
If a three-phase pump is installed, the direction of rotation of the impeller should be checked before final installation,
following the procedure indicated in the pump manual.
