On generator fitted with a
push button
, the LED light in the button will blink rapidly when an error
is detected; e.g. steam was turned on while the water supply was isolated or for some other reason
water flow to the generator was restricted. This error will also be generated if the water flow is
interrupted during operation. Error message can be reset by pressing the button. Fix the problem or
call in service personnel.
Circuit card includes 24V DC max 50 mA output for external alarms. The output is activated when
E1 or E2 errors occur or when the pressure button's led blinks rapidly. Alarms can be reset using the
ON/OFF button.
HSS M and HST M STEAM GENERATOR SERVICING
HSS M and HST M generators include a pre-programmed, automatic function, which drains and
rinses the tank after each use. This requires the use of an optional electric flush valve, Drain Kit M.
A long service life is also achieved by emptying the steamer tank immediately after use in areas
where the water is known to be hard or contain contaminants.
Note!
Draining the tank does not
preclude the need for the regular removal of lime from the tank.
Testing water quality and de-scaling for HSS M and HST M generators
Test strips included in the test pack supplied with the generator are used as follows: Submerge the
test strip into the water for approximately one second, lift it up and shake excess water off.
Compare the test strip to the colour coded instructions provided in the packet after waiting one
minute.
Test result:
<
3
°
dH, Very soft water, de-scaling after 500 hours of use.
>
4
°
dH, Soft water, de-scaling after 100 hours of use.
>
7
°
dH, Medium hard water, de-scaling after 50 hours of use.
>
14
°
dH, Hard water, de-scaling after 30 hours of use. Installation of the limescale
removal treatment equipment is recommended.
>
21
°
dH, Extremely hard water. Install the limescale removal equipment and test
water hardness again.
These maintenance intervals are the maximum times as recommended by the manufacturer.
It may be worthwhile carrying out the removal of lime even more frequently, when necessary.
Warranty for the equipment is void, if the generator installation or use is not in accordance
with what has been stipulated in these instructions.
The warranty also excludes functional problems, if they are caused by so called hard or
otherwise impure water.
The steam generator must be serviced as instructed in the user manual.
