Wall Installation; Maintenance; Accessory Tool; Emptying The System - DAB E.Sybox mini 3 Instrucciones Para La Instalación Y El Mantenimiento

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 ap-
pears as in Fig.19.

9. MAINTENANCE

Disconnect the power supply before starting any work on the sys-
tem.
The system requires no routine maintenance operations.
However, below are the instructions for performing the special mainte-
nance 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 inter-
face 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:
Figure 19
1. disconnect the power supply;
2. turn on the delivery tap closes to the system so as to remove pres-
sure from the system and empty it as much as possible;
3. f there is a check valve immediately downstream from the system (al-
ways recommended), 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 al-
ways recommended 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 horizontal 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).
