5 INSTALLATION
5.1 Positioning of cabinet
The cabinet should be installed in a room or outside in a rigid anti-
vandal cage, easily accessible, under normal ventilation conditions
and protected from impacts and freezing conditions.
5.2 Tank installation
Tank is designed to be installed at floor level.
The pit which should accommodate the tank must be sufficiently
deep that the water inlet pipe has a sufficiently high gradient once
the tank is built in.
If the inlet(s) is/are not deep enough, adjust by cutting one or more
rings from the upper part of the tank so that the part on which the
cover is placed is flush with ground level. If, on the contrary, the inlet is
too deep, use the supplied raiser: check levels horizontally and verti-
cally.
The tank must be placed in the pit on a bed of filler sand (size 0-32
mm): carry out ramming around the S.I.R. and finish with concrete if
necessary.
If the tank raiser has been used, orient the plastic tank so that the
upper part of the raiser accessory is flush with the natural terrain.
Maximum permissible difference of height between the upper part of
the tank and the natural terrain level: 700 mm (amount of raiser)
(Fig.7).
If raiser greater than 700 mm is used, the embed-
ding depth may result in more significant amount
CAUTION !
of excavated earth (depends on type of terrain).
5.3 Connection of collectors
- Saw the base of the most appropriate inlet sleeve and, in com-
pliance with industry standards, insert the inlet pipe (DN 150) into
the sleeve with a seal (see Fig. 5).
- Connect the discharge pipe (PE or PVC) to the discharge pipe
connector using the adapter. The discharge pipe must be protec-
ted from freezing conditions.
When the installation is completed, perform a pressure test on the
discharge pipe (DIN 4279, Section 1-9).
- Connection of the degassing pipe/cable feedthrough: saw the
base of the most appropriate inlet port (see Fig. 6) and connect the
degassing pipe/cable feedthrough (DN 100) using an insertable
sleeve.
Install piping so that degassing is induced by the slope with respect
to the tank. It is preferable to isolate the cable feedthrough vent
using expanding foam, to avoid gas leaking backwards (see Fig. 3).
Filling in the pit.
If the particle size of the earth excavated from the pit is not greater
than 32 mm, it may be used to fill in the pit. For larger and sharper fill-
in material, the tank wall should be protected by a 50-cm layer of
sand or gravel (max. size 32 mm). Fill in and pat down the earth even-
ly so that the tank is not deformed or compressed.
When underground water or high water reach highest levels, it is pos-
sible to reduce the risk of vertical loads on the tank by placing appro-
priate concrete pieces over the tank's fins (see Fig. 4). The concrete
weights must firmly rest on the fill-in material and not on the fins them-
selves. Place some sand between the fins and the concrete. Under
normal conditions, this protection is not required. To close the tank,
the high-strength plastic cover is equipped with a seal, designed for
terrain at risk of flooding. You can walk on the cover to close the tank.
On this cover (2 cases):
- Cover flush with ground level:
Prepare a concrete frame to allow the cover to be easily closed
and opened and such that no water is retained (incorporate a rain-
water drain).
- Cover higher than ground level:
Install a protection barrier so that walkers do not bump into the
cover.
- A tank raiser kit (see Fig. 7) is available as an option if the vent inlets
are installed very deep, or for safety reasons, to avoid freezing pro-
blems, extension, etc. Adjustment from 150 to 700 mm max.
- Before installing the tank raiser, connect the corresponding pipes
(vent and degassing inlets, discharge pipe) and fill in the pit to half
the height of the tank (stabilization fins).
- Insert the tank extension until its upper part is flush with ground level
(see Fig. 7, Item 1).
- Push the raiser sliding flat seal downwards to the upper part of the
tank and secure the tank extension in the desired position.
- Attach the raiser to the tank at the same level as the upper molding
of the tank using the screws supplied (see Fig. 7, Item 2).
- Slide the flat seal (Item 3) as shown in Fig. 7 in the upper groove on
the tank so that it is in contact with the largest possible surface area
with a small radius, without making any folds at the groove's surfa-
ce.
The surface between the seal and the groove must be clean.
- Finish filling in the pit.
We recommend that the installation engineer strictly com-
plies with health regulations relating to station aeration and
ventilation piping.
5.4 Pump installation
- Clean the tank.
- Secure the pump and the discharge pipe outside the tank using the
appropriate tools.
- The length of the cable between the control box and the pump
must be sufficient to allow the pump to be taken out of the tank for
future maintenance checks.
- Route the lines going to the control box (pump cable, control line
or IPA capillary) through the cable feedthrough. Keep a sufficient
line length at the side of the tank.
- Lower the pump with the discharge pipe into the tank using the
chain and secure it to the coupling. Secure the chain to the hook
incorporated in the tank.
- Attach the float support (Fig. 2, Item 8) in the appropriate notch in
the main cross-piece.
- Install the level control system, in compliance with the connection
and installation dimensions given in the supplied specifications
sheet (installation examples, Figs. 1 and 2).
- Bundle together the cables, capillary tubes, and all mobile lines
and secure them above the cleaning connector so that they will
not be pulled in by the pumped fluid or by the suction port close to
the blades. Do not compress or fold the cables.
5.5 Electrical connections
The electrical connections must be made by a qualified elec-
trician in compliance with local regulations.
Observe the instructions given in the installation manual and those
relating to starting the pump and the control box.
