Filling And Emptying; Service Water Connection (Pressure-Proof) - Austria Email SISS 350/100 Instrucciones De Uso

FILLING AND EMPTYING

Filling
It is bindingly necessary to fill resp. apply pressure to the inner service water tank first and then the buffer tank
(hot water area).
Emptying
When emptying the system, the buffer tank (hot water area) must be depressurised in the first step and then the
service water tank in the second step.
The enamelled service water tank may be destroyed in the case of a non-compliance with the filling or emptying
procedure!

SERVICE WATER CONNECTION (PRESSURE-PROOF)

Any warranty for our water heaters shall be rejected in case of use of unsuitable or inoperative storage connector
fittings as well as an exceedance of the specified operating pressure. To avoid damage, it is necessary to construct
the connection of the storage tank with a detachable connection (union).
Leaks from the storage tank as a result of an improper connection and damage and consequential damage caused
by this are excluded from the guarantee and product liability.
All water heaters provided with a rating plate bearing the designation 'nominal pressure 10 bar' (atmospheric
excess pressure kp/cm²) are pressure-proof storage tanks and can be connected on a pressure-proof basis using
a line pressure up to 5.5 bar.
A pressure reducing valve must be installed in the cold water supply line should the line pressure be higher!
The water plumbing must be performed by means of a certified diaphragm safety valve or a diaphragm safety
valve combination (connector fitting for pressure-proof storage tanks) only!
A safety valve combination consists of a shutoff, test, swing check, drain and safety valve with an expansion water
drip and is installed between the cold water supply line and the cold water supply of the storage tank in the order
as drawn.
Principally, the following must be observed:
In order to ensure a flawless function of the connector fitting, the same must be mounted in frost-protected
rooms only. The drain of the safety valve must be open and observable and the outlet pipe from the drop collector
(expansion water funnel) must lead into the sewer, so that neither frost nor clogging by dirt and similar can cause
any malfunction.
No shutoff valve or other throttling must be installed between the safety valve and the cold water supply of the
storage tank.
The safety valve must be set to a response pressure that is lower than the nominal pressure (10 bar) of the storage
tank. The cold water supply line must be rinsed out before the storage tank is connected finally. The discharge
