Checklist - Tylo VA 2,0 Instructions De Montage Et D'emploi

WARNING! SEVERAL SUPPLY CIRCUITS. CHECK
THAT THERE IS NO CHARGE IN THE MACHINE
BEFORE DOING ANY MAINTENANCE WORK!
Checking and fault-finding.
In the event of faulty operation, first check the following:
•
are the control panel and steam generator wired up in
accordance with the wiring diagram?
•
is the steam generator correctly installed in accordance
with these instructions?
•
does the drainage pipe slope down properly towards the
waste outlet?
•
is the filter clogged? The filter is located at the point
where incoming water is fed into the generator. To clean
the filter, disconnect the feed pipe, remove the filter and
rinse it free from particles of calcium carbonate and
other deposits.
•
are there any sags along the steam pipe or along the
ventilation duct leading from the steam room?
•
are there any sharp bends in the steam pipe? (the
minimum permitted radius of bends is 50 mm, 2")
•
If there is a tap on the water supply to the steam
generator, make sure this is not closed.
•
does the construction and ventilation of the steam room
comply with Tylö's instructions?

Checklist

with alternative causes of problems and suggested actions.
The steam room maintains the desired
temperature (40–50°C, 105–122°F), but no
steam is produced.
Cause: Insufficient ventilation in the steam room.
Solution: Increase ventilation. The ventilation is insufficient if
less than 10–20 cubic metres (13–28 cub. yd) of air per
person per hour is evacuated via the outlet vent. This
situation may occur if the outlet vent is not connected to
some form of mechanical extractor fan – or if the
ventilation duct is blocked by a water pocket.
Cause: The air coming into the steam room is too warm.
Solution: Reduce the intake air temperature to 35°C (95°F).
Cause: The ambient temperature is higher than 35°C
(95°F).
Solution: Ensure that the ambient temperature does not
exceed 35°C (95°F).
Cause: The thermometer is faulty or wrongly placed.
Solution: The thermometer should be placed
approximately 170 cm (67") above floor level and as far
away from the steam jet as possible.
The steam room requires an abnormally
long time to heat up.
Cause: The generator is not powerful enough. See table.
Solution: Replace the steam generator with one with a
higher heat output.
Cause: Excessive ventilation in the steam room.
Solution: Reduce the ventilation to evacuate 10–20 cubic
metres (13–26 cub. yd) of air per person per hour.
Cause: Blown fuse in the mains fuse box.
Solution: Replace the fuse.
Cause: The ambient temperature is lower than 15°C (59°F).
Solution: Increase the ambient temperature or replace the
steam generator with a more powerful one.
Cause: Heating element is broken.
Solution: Replace reservoir.
Cause: The thermostat sensor is too close to the steam
jet. See test 2.
Solution: Move the sensor or change the direction of the
steam jet.
Neither steam nor heat is generated in the
steam room.
Cause: Blown fuse in the mains fuse box.
Solution: Replace the fuse.
Cause: The water is not reaching the steam generator.
Solution: Open the tap(s) connected to the piping to allow
incoming water to flow into the steam generator.
Cause: The control panel is incorrectly set.
Solution: Check the time and temperature on the control
panel.
Cause: The filter is clogged.
Solution: Remove the filter which is placed in the
connection for incoming water. Clean off any metal filings
or other foreign bodies.
Cause: The solenoid valve for water supply has stuck.
Solution: Remove the solenoid valve and clean off any
metal filings or other foreign bodies.
Cause: Excessive calcium carbonate deposits in the
steam generator's water reservoir. See test 1.
Solution: Replace the entire water reservoir, including
heating elements and electrodes.
Cause: The steam generator is wired up for the wrong
voltage.
Solution: Check the voltage and the connection to the
generator – see diagram.
Cause: The temperature limit control has been triggered,
see test 4.
Solution: Check and remedy any faults on the steam pipe,
such as a blockage due to several sharp bends, water
pockets or greatly reduced internal diameter. The tank
may also be clogged with limescale; see above.
Cause: Flaw in the circuit board, control panel or magnetic
operated vent.
Solution: Replace the faulty component.
Hot water runs from the steam head. Little
or no steam in the steam room.
Cause: The solenoid valve for incoming water has stuck,
due to accumulated deposits of foreign bodies or an
electrical malfunction. See test 3.
Solution: Remove the valve and clean it, or rectify the
electrical malfunction.
Cause: The solenoid valve is broken.
Solution: Replace the valve.
Cause: Malfunction in the circuit board.
Solution: Replace the circuit board.
Hot water comes out of the steam head in
spurts or in a slight, even flow mixed with
steam.
Cause: Small water pocket along the steam pipe.
Solution: Eliminate the water pocket.
Cause: The steam pipe is uninsulated along too great a
portion of its length.
Solution: Insulate the steam pipe.
A continuous trickle of hot water from the
steam generator's drainage pipe.
Cause: The solenoid valve for automatic emptying has
stuck.
Solution: Switch off the steam generator. See what
happens again after an 80-minute pause. If the fault
persists, remove the solenoid valve for the automatic
emptying function and clean it.
Loud noises in the feed pipes when the
solenoid valve opens or closes.
Cause: The steam generator feed pipes are not sufficiently
secure.
Solution: Fix the pipes securely to the wall with pipe clips.
Cause: "Recoil" problems in the feed pipe (Pipe hammer).
Solution: Replace a metre-long length of piping nearest
the steam generator with flexible piping, for example,
reinforced rubber hosing, which will withstand the
pressure.
Safety valve opens or temperature cut-off is
activated.
Cause: The steam pipe is blocked; see test 4.
Solution: Remove the blockage.
Cause: The internal diameter of the steam pipe is
considerably reduced. See test 4.
Solution: Replace the pipe or the pipe joint which is
causing the reduction (Internal diameter must be at least
12 mm, ½").
Cause: Sharp bends ("elbows") along the steam pipe. See
test 4.
Solution: Get rid of "elbows" in the pipe. Bends are to be
gently rounded (minimum radius 50 mm, 2").
Cause: Large water pocket somewhere along the steam
pipe. See test 4.
Solution: Adjust the steam pipe to eliminate the water
pocket.
Cause: Excessive calcium carbonate deposits in the
steam generator's reservoir. See test 1.
Solution: Replace the entire reservoir, including elements
and electrodes.
Erratic steam production right from the
start.
Cause: The thermostat sensor is wrongly placed in
relation to the steam jet. See test 2.
Solution: Move the sensor or alter the direction of the
steam jet.
Cause: Calcium carbonate or other foreign bodies in the
filter.
Solution: Remove and clean the filter.
TEST 1.
Test for calcium deposits in the reservoir.
Unscrew the capping nut at the top of the steam
generator. Lower a torch bulb, wired up to a battery, into
the hole. Inspect the illuminated tank through the hole. If
there is a layer of calcium carbonate extending more than
three centimetres above the bottom of the tank, the
reservoir has not been serviced as prescribed with regular
applications of a de-scaling agent.
The problem may also be that the emptying and flushing
systems are no longer operative. If there is a switch along
the feed cable to the steam generator, check that this has
not been used as an OFF switch after steam bathing. A
switch in the feed cable must not be switched off until at
least 80 minutes after the control panel has turned off the
system.
Make sure that the automatic emptying function is
working, by placing a suitable vessel (capacity approx.
3 litres, 5 pints) under the drainage valve. Switch on the
steam generator and let it remain on for 15 minutes.
Switch off the generator in exactly the same way as you
always do when turning off the steam bath for the day.
Wait at least 80 minutes, and then check that the vessel is
full of water. If this is not the case, either the steam
generator has been incorrectly wired up, or the power to
the generator has been interrupted in some other way
along the cable from the electric supply to the generator,
or alternatively there is a fault in the drainage valve or the
circuit board.
TEST 2.
Temperature sensor test.
Soak a small towel in cold water. Hang the wet towel over
the thermostat sensor. If, within 20 minutes, the steam
generator has started to product steam continuously, the
equipment is not defective, but the thermostat sensor
(bulb) is located in an unsuitable position, or the
thermostat itself is set for too low a temperature. If steam
production does not begin, use the checklist to find out the
cause.
TEST 3.
Solenoid valve check.
Use the control panel to switch off the steam generator. If
water continues to trickle out of the steam head more than
10 minutes after the control panel has been switched off,
the cause is dirt in the solenoid valve. Remove and clean
the valve.
If the water stops running through the steam head within
10 minutes after the control panel has been switched off,
the cause is an electric fault (incorrect connection or circuit
board fault). Or, alternatively, excessive calcium carbonate
has accumulated in the reservoir. See test 1.
TEST 4.
Steam pipe test if the safety valve or the
temperature cut-off is activated.
Disconnect the steam pipe from the steam generator. Start
the generator and let it remain on for about 1 hour. If the
safety valve or the temperature cut-off is not activated
during this test, there is a blockage along the steam pipe
which is preventing the passage of steam. Take the
necessary steps according to the information in the
checklist.
If, during service, you wish to empty the tank,
disconnect the spade connector on the emptying valve
and connect the 230 volts' mains supply directly to the
solenoid valve.
IMPORTANT: This operation may only be carried out
by an authorised electrician.
