2.3.4 Expansion vessel connection
Connect the permeate pipe (white, 6-mm dia. pipe) to the T-shaped
connector (both included in the standard supply). Then, connect them to
booster BV1 valve of the expansion vessel (Fig. 2.g, 2.h).

Caution : it is advisable to install the expansion vessel close to the
WTS Compact, within a range of 3-5 metres. The distance of the user
depends on the diametre of the pipe used for the permeate and on the
pressure required to the feed water. With a permeate pipe having 10 mm
diameter and with a feed pressure request ≈ 1 bar, the recommended
distance should not exceed 20 metres.
2.3.5 Precharge of the expansion vessel
Precharge the expansion vessel using compressed air until reaching a
pressure lower or equal to the min. pressure of the permeate pressure
switch (~1.5 ÷ 1.8 bar). Charge the vessel through the valve located at the
bottom (see arrow, fi g. 2.e).
Caution
:
precharge the
expansion vessel at 1.5...1.8 bar

2.3.6 Storage tank connection
WTS Compact can also be installed with a storage tank equipped with
pump. In this case, the authorisation to operation does not depend on
pressure anymore (as it happened with the expansion vessel), rather it is
determined by the high/low level signal sent by the fl oat inside the tank.
In case of installation of WTS compact with storage tank, comply with the
following instructions:
•
open the case of the electronic controller.
•
disconnect the cables of the pressure switches from terminals 22-23
and 33-34 (factory fi t wiring).
•
connect the high level signal to terminals 22-23 and the low level
signal to terminals 33-34 (Fig. 2.g).
•
enable the high level signal from menu "5 HIGH LEVEL - LIVELLO ALTO"
(see paragraph 3.6).
•
enable the low level signal from menu "4 LOW LEVEL - LIVELLO BASSO"
(see paragraph 3.6).
•
In these menus you can set the logic of the contact (N.C. or N.O.) and
the delay of the signal (DEFAULT 00 sec.)
2.1 Electrical connections
Connect the system to the single phase line 230 V (50 / 60 Hz) single phase
through the supplied socket. The user should not install any other wiring,
unless for connecting an alarm output (to be connected to terminals 19
[N.O.]-20 [C]-21 [N.C.]) or an external remote consent (to be connected
to terminals 37 [common] - 38 [input]). For completeness purposes, the
diagram of all internal connections and available terminals follows:
