ADJUSTMENT AND CONTROLS
– To avoid leakage of the sealings and damage to the
components in and on the boiler, NEVER clean the boiler
with vinegar, a descaling agent or other chemicals.
– The boiler doesn’t contain serviceable parts
Never disassemble the boiler body and /or components on
and in the boiler.
– ALWAYS REPLACE THE BOILER ( 36) WHEN:
*
the mechanical safety valve ( 105 ) has been activated.
*
the pressostat ( 106 ) doesn’t function properly.
*
the thermo fuse ( 107 ), boiler thermostat ( 108 ) or
hand - resettable safety thermostat ( 109 ) are open,
because the boiler has been subjected to too high
temperatures.
*
the sensor ( 110 ) doesn’t function properly
*
the electrovalve ( 111 ) fails or the sieve is soiled with
scale.
–
After the product has been repaired, it should function
properly and has to meet the safety requirements as laid
down and officially established at this moment.

FUNCTIONAL DESCRIPTION OF THE HI 994 MASTER VAPOR
Description of the water supply.
Apin(1)inthebottom of the housing activates the valve in
•
the watertank.
The microswitch(2)makes sure that the electric circuit is
•
closed, provided the tank has been fit properly.
The reed contact(3)makes sure that the system switches
•
off when there is no sufficient water in the tank.
The floater in the tank(4)drops when water is
pumped to the boiler.
Once the floater is at the bottom, the magnet in the
floater activates the reed contact, so the reed contact
is openend and the circuit is interupted.
The light goes on.
Sensor(5)intheboiler activates the pump, when the
•
water level reaches the lowest specified water level.
The sensor detects the resistance between the sensor
and the water level.
When the water level is low, the resistance will be
rather high and the pump is activated.
When the water level is high, the resistance is low and
the pump stops.
The HI994 consists of an iron and a stand.
Cold water is pumped from the detachable tank to the boiler,
where steam is generated.
After operating the steam valve, steam flows into the iron.
The stand consists of:
I ) A detachable tank :
There is a floater in the tank, which activates the reed
contact.
II ) A pump :
The pump is protected against overheating by an
automatically resettable cut-out.
III) A boiler :
On the boiler the following controls are fitted
-
hand-resettable safety thermostat
-
boiler thermostat
-
fuse
-
pressostat
-
mechanical safety valve
-
sensor
-
electro valve + sieve
IV) An electronic control / steering unt, which consists of :
a PCB, located below the pump
a sensor, located in the boiler
Functioning of the system
– The water tank is filled with water and fitted on the stand.
– Switch is operated, light goes on, indicating that water
is being heated.
– Water is pumped from the tank to the boiler. This can be
clearly heared.
– Once enough water is in the boiler, the pump stops.
– When the pressure is within the limites 2 ± 0.3 bar, there is
sufficient steam to start ironing and the the pressostat comes
into operation and switches off the element.
–
Switch can be operated to start ironing.
Pilot light switch goes on.
–
Once the water level reaches the lowest specified level, the
sensor activates the pump.
–
The whole process starts again.
The pump is a vibration pump which makes noise during pumping.
This is normal. The pump doesn’t pump water continuously.
It pumps at the start and during ironing after finishing steaming.

POSSIBLE FAILURE CAUSES
COMPLAINT : WATER RUNS OUT OF THE SOLEPLATE
Check if temperature dial ( 21 ) is set to the highest position.
•
If steam dial ( 13 ) is set to the highest pos. and the temp. dial to medium or low position the
soleplate doesn’t become hot enough and the steam condenses.
Steam from former use condensed in the hose.
•
This is normal.
The water disappears when the iron heats up.
COMPLAINT : IT DOESN’T STEAM
operate the steam command lever ( 14 )
•
no click is heared
<
the electrovalve ( 111 ) is broken.
→
replace the complete boiler ( 36 ).
*
the microswitch of the steam activator is broken.
→
replace the component.
*
a “click” is heared clearly
<
the water supply is OK
<
GENERAL TEST :
connect the system to the mains, switch the boiler and iron on, set the temp. dial to the
•
highest pos.
when measuring : 800 Watts
<

“NUISANCE CALL” :
The pump has been provided with an automatical cut-out.
This cut out is activated when the pump becomes to hot.
This is caused by a not properly functioning of the water supply ( clogged with scale or dirt ) or
internal failure in the pump.
This happens after a relative long period of use.
After a cooling-down period the cut-out is reset automatically so it may function properly at the
repair shop.
When such a situation arises, check the water supply and/or pump as described before.
one-way valve is soiled
→
replace the valve.
