Wall Installation; Maintenance; Accessory Tool; Emptying The System - DAB E.SYBOX MINI 3 Instructions Pour L'installation Et L'entretien

8.2 - Wall installation

This product is already set up for installation hanging on the wall with the DAB accessory
kit, to be purchased separately. The wall installation appears as in Fig.19.

9. MAINTENANCE

Disconnect the power supply before starting any work on the system.
The system requires no routine maintenance operations.
However, below are the instructions for performing the special maintenance operations
that may be necessary in particular cases (e.g. emptying the system to put it away during
a period of inactivity).

9.1 - Accessory tool

With the product, DAB supplies a metal key with a hexagonal section (Fig.20 – 1) useful
for performing some special maintenance operations on the system, or during installation.
In particular, use the key for the orientation of the interface panel described in par. 2.2.2
or for opening the door of the compartment next to the interface panel. If the key is lost or
damaged, the operation can be done using a standard 2mm allen wrench.

9.2 - Emptying the system

If you want to drain the water out of the system, proceed as follows:
1. disconnect the power supply;
2. turn on the delivery tap closes to the system so as to remove pressure from the
system and empty it as much as possible;
Figure 19
3. f there is a check valve immediately downstream from the system (always recom-
mended), close it so as not to let out the water that is in the plant between the system
and the first turned on tap;
4. interrupt the suction pipe in the point closest to the system (it is always recommend-
ed to have a check valve immediately upstream from the system) so as not to drain
the whole suction system;
5. remove the drainage cap (fig.1 face E if vertical configuration; fig.1 Face C if horizon-
tal configuration) and let out the water inside (about 1.5 litres);
6. the water that is trapped in the delivery system downstream from the non-return
valve integrated in the system can flow out at the time of disconnecting the system,
or on removing the cap of the second delivery (if not used).
Though essentially drained, the system is unable to expel all the water that it
contains.
During handling of the system after emptying it, some small amounts of water
may probably leak out from the system.
