Blow-off line
-
Size the blow-off line for a fully opened safety valve. The blow-
off aperture of the safety valve must remain open towards the
atmosphere.
-
Install the safety valve blow-off line with a constant slope.
Safety equipment
C E All safety components must be installed into the cold water
supply (Os. 35, 37, 38, 40). The order of the individual fittings must be in
accordance to local regulations.
The pressure regulator (40) has to be set to 150 PSI (10 bar). It can only
be installed into the cold water supply. The supply has to be thoroughly
inspected prior to installation. Installation of dirt filters or any other
narrowing of the supply line to the pressure relief valve is forbidden.The
pressure relief valve (13) has to be easily accessible. Expansion water
generated during the heating has to flow visibly to a drain.
The drainage pipe must be large enough to accommodate water
drainage with a fully opened T & P valve (32). The drainage pipe must
be protected from freezing and must not lead outdoors.
The pressure regulator (40) has to be set so no water drips from the T &
P valve (32).
Heavy dripping of the T & P valve (32) can be caused by dirt in the valve
seat or water pressure. Water pressure needs to reregulated below 150
PSI.
Prior to filling all screws must be tight.
Drainage of the hot water tank is via the drain valve (37).
»
Install dirt strainers or other restrictions in the safety valve supply
line.
»
Only fill the device with water by opening the DHW fitting and flush
thoroughly.
»
Carry out a leak test.
A re-circulator can be attached to a separate socket across the
thermometer. Drill the outer casing with a hole saw Ø 50 where marked
and remove insulation from the socket in that area.
For energy conservation, use of a circulator is not recommended.

2.5 Connection to the Solar Unit
C The installation of the solar loop is shown in picture C. The solar
loop must include temp/pressure relief, an air-vent (21), a check valve
(32) and an expansion tank (28). Refer to the separate operation and
installation instructions for the solar collector SOL 25 plus.
Test operation after installation. Start up must follow the
!
approval of the installer (refer operation and use).
2.6 Hot water temperature probe
A
F The hot water temperature probe is to be installed into the
upper immersions sleeve (Pos. 3).
For this, place the spacer at the temperature sensor and push it into the
sensor well
F
2.7 Solar Storage Tank – Temperature Probe
A The solar storage tank temperature probe to lower immersion sleeve
(6) of the hot water storage tank.
The temperature probe must be completely inserted into the probe
sleeve.
