Connections; Pipes And Draining Off Condensation - Ferroli FCM 400 Manual De Instalación

CONNECTIONS

The selection and sizing of the hydraulic lines is delegated responsibility
for the designer who must operate under the rules of good practice and
legislation .
- Position the hydraulic lines
- Tighten the connections using the "key against key" (Fig 1)
- Check for leakage
- Coat the connections with insulating material
The hydraulic lines and joints must be thermally insulated . Avoid partial
insulation of pipes .
Do not over tighten to avoid damaging the insulation .

PIPES AND DRAINING OFF CONDENSATION

For the production of the condensate discharge
pipe it is preferable to use a rigid PVC ø 32 mm
inner tube .
Mod . 400 400-4T
- The units are equipped with a
pump which is able to guarantee a
rise in condensation water from the
bottom of the unit (as shown in the
figure) not exceeding 500 mm for
the 400 and 400-4T models; and
750 mm for other models (Fig .3-A) .
- To drain the water to a higher level
of the unit, install an auxiliary con-
densate drain pump with collector
tray and level regulator
-For a regular discharge of con-
densation it is necessary that the
drain hose has an inclination of 1%
downwards without bottlenecks or
ascending tracts (Fig .3-B) .
-In addition, have a deep siphon
of at least 50 mm to prevent bad
smells in the environment (Fig .3-
C) .
-For more than one unit installed in
a room, the condensate drainage pipe must be as in (Fig.3-D). The main manifold must be dimensioned to drain
all the units at the same time .
-The pipes must be covered with anti-condensate materials, eg polyurethane, polypropylene, neoprene or expan-
ded foils of 5-10 mm thick.
