Vent Pipeline; Check Valve; Stop Valve; Positioning The Pumps - Zenit blueBOX Manuel D'utilisation Et D'entretien

blueBOX - Translation of the original instructions
is not subject to flooding.
Once the water system and electric connections have been made, the lifting station should be complete surrounded with clean sand to prevent it
from shifting during operation.
Once the lifting station has been installed in the ground, the cover can be walked over but will not support vehicles.
For greater safety, a manhole can be installed over the cover of the blueBOX; its weight must not rest on the lifting station itself. In all events,
enough room must be provided for any maintenance work.

4.3 VENT PIPELINE

The vent pipeline is installed to prevent the formation of explosive or toxic mixtures of gases and to prevent pressure build-ups when liquid enters
the tank, or vacuums during pumping.
Local regulations may require different vent pipeline diameters.
Zenit recommends a vent pipeline of at least 75 mm, installed using the gasket provided, in one of the connections provided in the top of the blue-
BOX. The tank is supplied complete with a through-wall fitting to which a vent pipeline with minimum inside diameter of 38mm (1"½) can be fitted;
however, whether this is used will depend on the installation type and pipeline length.
The vent pipeline must be perfectly sealed to the tank intake and the other end must be installed outdoors, at a suitable height and with a flame
prevention filter if necessary.

4.4 CHECK VALVE

A check valve should be installed on the outlet pipeline connected to the sewer system to prevent flow-back into the lifting station.

Zenit is able to supply the blueBOX fitted with a bottom coupling device with integral check valve and a patented system to vent any air which forms
in the pump body during a lengthy period out of use.

4.5 STOP VALVE

Stop valves must be installed on both the intake and the outlet pipelines to allow maintenance to be carried out in safety. Gate valves or ball valves
can be used for this purpose.

4.6 POSITIONING THE PUMPS

The cover, or covers in the case of a double station, are fixed to the tank by means of screws; unscrew the covers with the aid of a spanner and
remove it/them.
For three phase electric pumps it is fundamental to check that the rotation is direct before fixing the pump in position (procedure explained in the
electric pump operator's manual). The pump installation mode depends on the type of blueBOX, depending on whether a bottom coupling device
or direct coupling is used. When installing with direct coupling, place the pump on the bottom of the tank in the position indicated by the mounts
provided on the bottom (raised projections which will hold the pump stable during operation).
Fit the pipe into the outlet hole in the top of the tank, fitting the cable clamp gasket and the plastic ring-nut onto the pipe.
Now screw the outlet pipe onto the pump outlet port. Next, tighten the ring-nut.
If the blueBOX 60, 90 and 150 are being used, the pump is fitted with a PVC pipe with connection which allows the pump to be separated from the
outlet pipe without dismantling the pipe from the system.
For electric pumps with horizontal outlet, the lifting station can be fitted with a bottom coupling device already installed together with the outlet pipe.
Ensure that the pipe clamp is firmly tightened to prevent unpleasant smells from escaping. Connect the sliding flange to the pump outlet port and
then fit the pump-flange assemble on the coupling feet with the aid of the guide pipes.

4.7 EXTRACTING PUMPS FROM A blueBOX

To extract vertical outlet pumps from the blueBOX 60, 90-150 proceed as follows: (FIG. 1/A-B-C-D)
1 Unscrew the cover fixing screws
2 Remove the cover
3 Disconnect the outlet ring-nut and release the rubber cable glands
4 Move the pump towards the opening at the top
5 Extract the pump through the opening left by the cover
To extract vertical outlet pumps from the blueBOX 250-400 proceed as follows: (FIG. 2/A-B-C-D-E)
1 Unscrew the cover fixing screws
2 Remove the cover
3 Disconnect the outlet ring-nut and release the rubber cable glands
4 Remove the outlet gasket
5 Unscrew the pump outlet pipe
6 Extract the pump through the opening left by the cover
To extract horizontal outlet pumps installed with coupling foot, proceed as follows: (FIG. 3/A-B-C)
1 Unscrew the cover fixing screws
2 Remove the cover
3 Lift the pump by means of the handle until it is free of the guide pipes

4.8 HYDRAULIC CONNECTIONS

The water system connections must be made by a qualified installation engineer.
blueBOX lifting stations offer a variety of pipeline intake and outlet options. For the outlet, Zenit can supply the station complete with a length of
pipe connected to the electric pump or coupling device to simplify connection to the rest of the system.
At the sides, the station has a variety of fittings for the intake pipes. One or more holes should be made in the best position for the user's instal-
lation (FIG.4).
To install the intake pipes, a hole must be made in the tank with a drill fitted with a flared grinding tool of the appropriate diameter for the pipe.
The rubber gasket guarantees a perfect seal with no need to use additional sealants.
