Tylo VA 2,0 Instructions De Montage Et D'emploi page 5

IMPORTANT!
• Do not make sharp bends or "elbows" along the steam pipe.
• Do not direct the steam jet at a wall, seating or any other
object. There should be a free space of at least 70 cm (28")
in front of the steam nozzle.
• Do not allow sags or "water pockets" along the steam pipe
and/or the ventilation duct. IMPORTANT! There must not be
any type of obstruction along the steam line, such as a stop-
off valve or tap. The internal diameter of the steam pipe
must not be reduced.
• Ensure that steam rooms that are used continuously for
more than two hours at a time are ventilated by 10–20 cubic
metres of air per person and hour.
• The power supply to the steam generator via the feeder
cable must not be broken. For that reason, avoid switches,
etc., along the feeder cable.
• Make sure that the drainage pipe slopes all the way down to
the waste outlet.
• The ambient temperature outside the steam room and around
the steam generator must not exceed 35°C.
• Place the thermostat sensor as far away from the steam jet
as possible.
• De-scale the steam generator at regular intervals as
instructed. (Please read the section 'De-scaling' for further
details). In hard-water areas, where calcium levels exceed
5-dH, we recommend the installation of a water softener or a
Tylö automatic de-calcifier.
• Clean the steam room regularly. See the section on
"Cleaning the steam room" under Operating instructions.
• CAUTION! Stay at least 12" (30 cm) away from hot steam
escaping from steam outlet.
•
IMPORTANT. The steam generator's wastepipe must always
discharge into a drain outside the steam room itself. The
water is very hot.
General Information.
Fig. 1.
Examples of ventilation, electrical and plumbing
installation.
X = feeder cable from mains to steam generator. Do not fit
a switch along this cable. Where local regulations
require a switch to be fitted, this switch must always
be in the ON position. If the electrical supply is
interrupted before the automatic emptying and
flushing functions have occurred (approx. 80 min
after completion of bathing) these functions are
terminated without the reservoir being emptied. This
reduces the life expectancy of the steam generator.
Y = control cable from mains supply via control panel to
steam generator.
V = thermistor cable.
Z = cable to external on/off switch (if any).
D = steam pipe.
E = drainage pipe.
F = incoming water.
G = air inlet.
H = air outlet, leading out via a ventilation duct into the
open air.
The steam room.
The steam room should not have any other source of heat
than the steam generator. The ambient tempera-
ture around the steamroom and the steamgenerator
generator should not exceed 35°C (95°F). If there is a
sauna next to the steam room, the sauna must be well
insulated, and placed so as to give at least 10 cm (4") free
space between the outside walls of the sauna and the
steam room.
Location of the steam generator.
The steam generator must be installed by an authorised
electrician/plumber. The steam generator must be
permanently installed. It is to be located outside the steam
room itself, but as close to it as possible – no more than
15 m (50 ft) away.
The steam generator must be placed in a dry and
ventilated space with a waste outlet, above, below or on
the same floor as the steam room, and concealed in a
cupboard, wardrobe, etc. (Never directly above a waste
outlet or in an aggressive environment).
The steam generator must be mounted horizontally, at a
suitable height above the floor to permit the drainage pipe
to slope towards the waste outlet. To achieve this, it may
sometimes be necessary to place the steam generator on
wall brackets, or a floorstand.
CC control panels.
Instructions: included with the control panel.
To be installed outside the steamroom, at any distance
from the steam room.
CC panels are electronically operated and are available in
the following models:
CC 10-3. Manual and automatic on/off. Maximum
3- hour running time, 10 hour pre-set.
CC 10-10. Manual and automatic on/off. Maximum
10- hour running time, 10 hour pre-set.
CC 50. Manual and automatic on/off. Maximum
3 or 12 hour running time, 10 hour pre-set.
CC 100. Manual and automatic on/off. Maximum
3 or 12 hour running time, 24 hour pre-set. Built-in weekly
timer.
CC 300. Manual and automatic on/off. Maximum
24 hour´s running time, 24 hour pre-set. Built-in weekly
timer.
Thermometer.
The thermometer in the steam room should be placed at a
height so that the temperature corresponds exactly to the
numbers in the names CC 50/ CC 100/ CC 100.
Temperature limit control.
Tylö steam generators are equipped with a built-in
temperature limit control. If the control is triggered off, consult
the checking and fault-finding list in this manual to find the
causes and a solution to the problem.
Main power switch.
On the bottom of the smaller steam generators is a power
switch, which should only be used if the unit is to be
disconnected for a long time. The automatic emptying
function ceases any time the power is cut off.
Floors and drainage.
There must be a drain in the steam room, and the steam
room floor must slope towards the drain. The floor may be
covered with seamless vinyl flooring, quarry tiles, etc. The
requirements for sub-floor work, joining, etc., are the same
as for an ordinary shower.
PLEASE NOTE. Contact with steam and hot water may
cause plastic wallcovering/flooring close to the steam
head to become slightly discoloured.
Ventilation.
As a general rule, steam rooms which are in use for less
than two hours at a time require no special ventilation. In
order to ensure proper hygiene and trouble-free operation,
steam rooms which are in continuous use for more than
two hours at a time should be ventilated with 10–20 cubic
metres of air per person and hour.
If there is a gap above the steam room, do not seal it. To
ventilate a cavity above the sauna, drill or cut at least one
ventilation hole (1000mm²) into the cavity through the wall
on which the sauna door is located.
The air inlet may be an opening placed low down on the
same wall as the door, or it may be a gap under the door.
The air outlet should be located high up on a wall or in
the ceiling, and as far away from the air inlet as possible.
However, the air outlet must not be located above the door
or directly above any of the seats. Connect the outlet to a
ventilation duct discharging into the open air. Use existing
ducting, if possible. The ventilation ducting must be 100%
steamtight and watertight, and made of materials which
will not deteriorate or corrode in the high humidity. Do not
allow the formation of "water pockets", caused by sags in
the ducting, where condensed steam may collect as water
and cause a blockage. If a water pocket is inevitable,
install a trap to drain the condensed water into the waste
outlet.
The air outlet vent must be of sufficient size to allow the
evacuation of 10–20 cubic metres of air per person and
hour.
Mechanical ventilation. If the unassisted through-flow of
air is insufficient, due possibly to negative pressure in the
room supplying air to the steam room, a mechanical
exhaust fan must be installed and adjusted to extract a
minimum of 10 and a maximum of 20 cubic metres of air
per person and hour.
Steam generator functions.
All Tylö Model VA/VB Steam Generators incorporate these
features: Stainless steel water reservoir
heating elements, resistant to rust and acid
emptying 1 hour after the steam bath has been switched
off Automatic flush function rinses 4 times after
emptying 3-part output Electronic water-level
regulator Electronic water level control
calcium-repellent electrodes Continuous steam
production Always the right output, regardless of
quantity and quality of water Built-in safety valve
in temperature cut-off Built-in filter
remote-control operation Adjustable steam head
Splashproof finish.
Automatic emptying.
This automatic function considerably reduces the build-up
of calcium carbonate and other deposits in the water
reservoir. Do not switch off any switches between the
mains supply and the steam generator until at least 80
minutes after the control panel timer has turned the
system off, because otherwise, the automatic emptying
and flushing of the water reservoir will not start.
WARNING! The water in the tank is hot
Automatic flushing with DIP
switch.
The steam generator is factory set to flush out part of the
water automatically after 4 hours. The steam generator
should, however, be emptied more frequently in areas
where the water is hard (5dH° or more than 100 ppm
calcium carbonate), or if it is used for more than four hours
per day. Set the required interval using the DIP switches
as shown (fig. 17).
WARNING. The water is very hot.
De-scaling.
Some of the limescale released from the water in the
steam generator is flushed out in the automatic emptying
and cleaning process; some, however, remains. The Tylö
Automatic De-calcifier (art no. 9090 7000) does not
remove limescale deposits as such, but modifies the ions
in such a way that more of the calcium is evacuated during
the flushing process. For this reason it is essential to
check that the automatic emptying function of the steam
generator has not been impaired by incorect wiring. The
reservoir must be emptied each time it has been used.
To maximise serviceable life and reduce the need for the
manual removal of limescale deposits, we recommend
that steam generators for use in public facilities should be
connected to a water softener which removes calcium
from the water. This is particularly important if the
hardness of the water is greater than 5 degrees German.
(5-dH, see table.)
The water softener must not generate any froth on the
water nor produce any harmful chemical reactions. If so,
the generator may indicate the wrong water level and
trigger the temperature cut-off. (Repeated activation may
result in the failure of the elements.)
The manual removal of limescale must be carried out at
regular intervals as specified in the table below.
For normal private use, there is little need for the manual
removal of limescale, unless the water is very hard. Even
so, it is advisable to de-scale the steam generator at least
once per year. This removes calcium and other deposits
that have become encrusted on the walls and elements of
the water reservoir.
Instructions for de-scaling Tylö Steam Generator
• Switch on the steam generator and let it run until the
water in the tank begins to boil.
• Switch the generator off and wait for approximately 5
minutes.
• Unscrew the capping nut from the 3-way connector on
top of the steam generator.
• Use a funnel to pour the de-scaling agent into the tank
via the 3-way connector.
• Screw the capping nut back in place on the 3-way
connector and leave the de-scaling agent to work.
• After approximately 1 hour the generator will
automatically empty and flush the tank. After this the
steam generator is once more ready for use.
Tylö Solvent is harmless, odourless, will not damage the
components in the steam generator and allows you to use
the steam generating function during the de-scaling
process. If you use any other type of de-scaling agent, do
not use the steam bath until after the de-scaling operation
has taken place.
As the table shows, how often manual de-scaling needs to
be done depends on the quality of the water, the output of
the steam generator and the total operating time.
