Initial Operation; Operation; Incremental Heating Test; Warranty - oventrop Multidis SF Einbau- Und Betriebsanleitung

The outlet ports of the distributor/collector are
closed with the caps G2 female thread (acces-
sories: item no. 1414493).
The ball valve DN 50 (accessories: item no. 1406586)
is mounted with the help of the collar nut (female
thread G 2 with flat seal). The risers are for instance
connected to the female threaded port of the ball
valves by using the Oventrop "Combi-System":
• Composition pipe "Copipe"
• Press fittings "Cofit P"
The pipes have to be insulated against heat loss
and for soundproofing according to the valid rules,
standards and regulations.
The surface heating/cooling circuits are connected
to the G1 compression connections of the flow dis-
tributor and return collector.
6.3. Floor construction
The object-related floor construction is specified
by the planner and the structural engineer.
6.4. Filling, bleeding, leak testing
The installation is filled up to the brass distributor/
collector "Multidis SFI" via the risers with the ball
valves being opened. The "Optiflex" ball valves (ac-
cessories: item no. 1033314) are used for bleeding
the system even under working conditions. They
are connected to the G
spective distributor module in the supply and re-
turn (illustr. 10.1).
The surface heating/cooling circuits are filled via
the "Optiflex" ball valves (accessories: item no.
1033314) with the ball valves being closed. The
surface heating/cooling circuits are flushed sepa-
rately so that the pipework is completely filled with
water.
ATTENTION
Carry out leak test according to DIN 1264. The
test results and the test pressure must be
recorded.

6.5. Incremental heating test

The earliest possible start of the incremental heat-
ing test depends on the thickness and quality of
the concrete floor. The incremental heating test is
carried out after consulting the concrete installer
and the structural engineer in accordance with their
specifications.
The incremental heating test must be carried out
manually or by a special controller programming.

6.6. Initial operation

ATTENTION
The flow temperature must be co-ordinated
with the surface heating/cooling system.
The maximum permissible screed temperatures
according to DIN must not be exceeded near the
heating pipes. In cooling systems, the temperature
near the cooling pipes must not reach the dew
point. The general instructions of the manufacturer
must be observed.

7. Operation

7.1. Regulation
Hydronic balance of the heating/cooling system
has to be carried out amongst the various risers.
Regulation of the surface heating/cooling circuits
is carried out at the brass distributor/collector
"Multidis SFI".
7.2. Setting of the regulating inserts (illustr. 7.1)
• Setting is carried out whilst the pump is in oper-
ation.
• Remove cap of the regulating insert.
• Close valve stem clockwise using an Allen key
(size 6).
• The presetting value is obtained from the design
chart (illustr. 9.1).
• Now open valve stem anticlockwise according
to the determined presetting value (example:
presetting 3.5 = 3.5 turns).
