INSTALLATION
.
Install DGFIT on the wall by using the indicated holes.
DGFIT must be installed:
-
In a
ventilated room, protected from the elements and
from exposure to the sun
-
Vertically, as close as possible to the pump that controls
-
Must have minimum space (upper and lower) indicated in
DIMENSIONS and WEIGHTS, for access and cooling
-
It should not receive harmful vibrations
-
It should not work in dusty or high relative humidity
environments
SURGE TANK
-
accumulates water under pressure to minimize the start-up of the pumps
-
it is essential in the presence of small system leakages
-
absorbs overpressures from the system
-
the minimum tank volume, in liters (for diaphragm models) is approx. equal to 10% of the
maximum capacity of the single pump, expressed in l/min; example in a standard application:
Qmax = 80 l/min
V = 80 x 10% = 8 liters
rounded up to commercial size
-
pre-charge: a. 50% of the working pressure: e.g.:
Pset = 4 bar
Ppre-charge = 2 bar
