FLUSHING AND RINSE
The generator should be emptied after each use. Since chalk and scale will naturally adhere to the
internal components, it is important to drain the tank while the water is still hot. This ensures that
no chalk builds up on the elements, tank or sensors. Install an 18/16mm copper or heat resistant
silicone pipe from the flushing valve into the floor drain. The pipe's internal diameter should be
approx. 14-16mm. NOTE: draining the tank does not preclude the requirement for regular removal
of lime from the tank.
As an
additional extra
, the generator can be fitted with an electrically operated Drain Kit M,
(automatic flushing and rinsing function). After 15 minutes from the shutdown of the generator, the
electric flushing valve will open. When the tank is empty, the generator will refill with cold water
and flush again (rinse). This function is in both control module and pressure button versions.
In the pressure button version, when the generator has stopped, the LED by the button will flash
every second during the 15 minute waiting time before the flush and rinse. After the cycle has run,
the generator will await a new start-up command.
ELECTRIC FLUSHING VENT Drain Kit M (Optional extra)
HSS M and HST M generators flushing vent installation
- Use PTFE pipe tape to seal the thread in the electric valve connection.
- Connect the cable provided into the electric valve and lock it in place with the lock nut. The other
end of the cable is connected directly to the AMP terminals on the circuit card. (see connection
diagram.)
NOTE!
Electrical connections can only be made by a qualified electricia
- Install a pipe from the flushing valve into the floor drain.
NOTE!
Drainage of water from the tank
relies on gravity so the generator must be installed higher than the floor drain.
ALARMS
Control module
E1
At start-up or while the steam generator is running, indicates interruption in water supply to the
generator. Check that the stop valve is fully open and that the filter in the water feed connection is
clean. If the problem is in the generator, it might require service.
E2
Indicates failure in the circuit between the control module and the generator. Service is
necessary
The generator will stop when an error is detected. Fix the problem or call in service personnel.
Control module can be reset using the ON/OFF button.
