Instructions for assembly:
Remove the tank cover, releasing the 6 clips(229). The maximum level reached in the tank with the
standard float is 285 mm from the tank bottom. If it is necessary to maintain a lower maximum level,
the standard float must be replaced with the float type B (standard supply) (fig. page 12 ). With this
float it is possible to limit the maximum level of water in the tank to 110 mm. A typical application is
for a shower drain. To change the float, slacken the screw (26) and extract the standard float from the
horizontal pin onto which it is keyed, fit the float type B, performing the same operations in inverse
order, and secure it with the same screw..
Insert the pump between the two anchoring points on the bottom of the tank and make the following
hydraulic connections:
INPUT:
(for the input references, see the example of installation on page 41)
2 on sides A and B: to use these inputs a hole must be made in the box on the marks and the
adapters (119) must be fitted for PVC pipes with external diam. = 40 mm, or internal diam. = 50
mm, to be glued on with adhesive type “TANGIT” (HENKEL). The gaskets (64a) must be
applied on the outside of the tank.
1 on side C: to use this inputs a hole must be made in the box on the mark and the ¾” hosetail
(119a) must be fitted for rubber pipes with external diam. = 25 mm. The gasket (64b) must be
applied on the outside of the tank. It is recommended to secure the pipe to the sleeve with two
hose-clamps. When used for a washing machine drain, install a siphon (not supplied) between the
machine and the collecting tank, so as to avoid the overflow of liquid when it is not in use.
1 on the cover D: for pipes with external diam = 30 or 40 mm. To use this input, make a hole in
the cover in the place provided, without damaging the seat of the rubber sleeve. Use one of the
clamps (84) or (84a) supplied in the accessories kit to ensure the seal between the input pipe and
the cover.
DELIVERY:
Fit the no return valve (137) supplied in the accessories kit, screwing it onto the output mouth, after
fitting the sealing gasket (64a) between the tank and the valve. Tighten it to ensure the seal of the
gasket. Directly connect the delivery pipe with internal thread 1¼” or fit the connecting union (161)
to use a rubber delivery pipe with internal diam. = 32 mm, to be secured with a hose-clamp.
Before replacing the cover on the tank, test the connection with clean water, after having connected
the pump to the mains.
VENTILATION:
The ventilation duct E may be made using a PVC pipe with external diam = 30 or 40 mm, to be
connected to the cover of the tank with a rubber clamp (84) or (84a) supplied as standard in the
accessories kit. Avoid horizontal stretches. If it is not possible to make a pipe, the seat for pipe
connection may be fitted with a valve with filter. To fit the valve, refer to the diagram on page 12 and
insert all its components in the valve housing, proceeding in this order: float ball (49), seal ring (16a),
safety valve support disc (180), O-Ring (95), rubber clamp diam. 490 mm (84a), breather cap (26).
6. IMPORTANT
6.1
Install the tank in a position protected against frost.
6.2
The tank may stand on the floor or be placed in a masonry pit. In any case the surface on
which it rests must be perfectly horizontal and the whole of the bottom of the tank must rest
on the surface..
6.3
Ensure that the difference in level between the pump and the sewage mains is compatible
with the pump performance.
6.4
The tank should be ventilated in any case.
