INSTALLATION
Connection of water.
If the oven is fitted with a built-in steam generator this
must be connected to cold water.
Connection is made to the solenoid valves (figs. 25,
26) on the rear of the oven.
Water pressure should be 4-6 bar (60-85 psi). Lower
water pressure gives lower steam capacity.
To avoid malfunction, it is important that the pipe is
flushed carefully, so that any rubbish left inside does
not block valves and nozzles.
If the water contains dirt particles, e.g. rust, a filter
should be installed upstream of the valves. This
reduces the risk of malfunctions.
If the water is very hard, a water softener should be
installed upstream of the valves to prevent lime
deposits from forming in the valves and nozzles. A
suitable water softener can be obtained from Sveba
Dahlen or one of our retailers.
The nozzle pipe seals to the steam generator with a
conical seal, and therefore no thread tape is needed
between the inlet pipe and the hexagonal cap.
Connection of drain.
Under the pipe there is a pipe which on delivery is fitted
with a 3/8" hexagonal cap. This pipe is a drain pipe from
the steam generator, and is used to empty the steam
generator of surplus water.
We recommend that the drain pipe should be connected
to a steam trap, so that the steam generator is
automatically drained after every steam cycle (Fig. 25).
The valves can also be drained manually.
A ball valve with drain pipe is fitted to each steam
generator. At least once a week the impurities in the
steam generator should be flushed out.
To do this open the ball valve and press the steam control
on the instrument panel. The impurities will then be flushed
out, which increases the service-life of the steam generator
and its elements. After this close the ball valve again.
The steam generator must be heated before it can be
flushed.
WARNING! Steam and hot water sprays out from
the drain pipe when flushing. This can cause
severe burns if you are careless.
