KEY
The following symbols have been used in the discussion:
Situation of general danger. Failure to respect the instructions that follow may cause harm to persons and property.
1. WARNINGS
Check that no damage has been done during transport or storage. In particular, ensure that the external casing is perfectly entire and
in excellent condition; check the efficiency of all the tank components and, if necessary, replace any parts that are not in perfect working
order.
2. DIMENSIONS AND WEIGHTS
The adhesive label on the package indicates the total weight of the system. The dimensions are given on page 21
3. METHOD OF USE
NOVA BOX is a pre-assembled system, ready for installation, without any need of regulation, ideal for collecting and disposing of domestic
waste from basement premises, located below the level of the sewage network.
It is NOT suitable for conveying waste sewage and corrosive liquids.
Max. liquid temperature: 50°C continuous - up to 90°C for maximum 3 minutes.
In accordance with the accident-prevention regulations in force, the NOVA BOX may not be used for conveying inflammable or explosive liquids,
such as petrol, diesel fuel, fuel oil, solvents, etc.
4. INSTALLATION
The NOVA BOX is supplied with a NOVA 300 pump that is not connected to the tank couplings.
For the part references concerning assembly, see the assembly diagram on page 22
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 22 ). 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 25)
•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
