SATA top air | 4
Prior to putting the unit/spray gun into operation, read the oper-
ating instructions completely and thoroughly. The stipulations
contained therein are to be respected in any case. After that, the
operating instructions are to be stored in a safe place, accessible
for every user of the equipment. The unit/spray gun may only be
put into operation by persons familiar with its use (professionals).
Inappropriate use of the unit/spray gun, modification of any kind
or combination with inappropriate other parts may cause material
damage, serious hazard to the user‘s, other person‘s or animal‘s
health or even death. SATA shall not take any responsibility for
such damages (e.g. failure to respect the stipulations laid out in
the operating instructions). The applicable safety, workplace and
worker health protection regulations of the respective country or
area/district in which the system/the spray gun is used are to be
respected in any case (e.g. the German Rules for the Prevention
of Accidents BGR 500 (BGV D25) and BGV D24 issued by the
Central Office of the Professional Trade Associations, etc.).
2. Functional Description
The breathing air purified in advance filters or, additionally, in the
belt unit is fed into the humidifier by the compressed air supply
hose (1). Upon streaming through the humidifier's diaphragm
module (3), the air becomes automatically saturated with mois-
ture. The purified and humidified breathing air is ready to be sup-
plied to a full face or half mask respirator, by the outlet coupling
(11). While air is passing through the SATA breathing air humidi-
fier top air, there is no pressure drop, resp. no remarkable air
loss. The water contained in the water storage (4) automatically
penetrates the diaphragm threads of the humidifier module (3),
always in a precisely sufficient quantity for optimum saturation
of the air. If there is no air stream through the humidifier, water
flow from outside to inside is interrupted, and therefore droplet
formation is prevented.
3. Putting into Operation
When putting the unit into operation for the first time, or after long
breaks (several days), the water storage (4) must be filled while
being in a vertical position until the maximum filling level (5), after
removing the closing screw of the filling opening. After this, wait
for 20 minutes to allow the diaphragm threads to become satu-
rated with water and reach their maximum mechanical stability.
In case the unit is put into operation too early, without waiting
time, the diaphragm threads may be damaged, and water may
penetrate in an uncontrolled way into the air passages. Always
fill the SATA top air humidifier while the unit is in vertical position.
Upon reaching the maximum filling level (5), insert and tighten
again closing screw of the filling opening. After the 20 minutes'
waiting time, connect the unit to the belt unit by the air supply
hose (1), while the respirator is already coupled.
Attention:
The outlet coupling for respirator connection is
no self-shut coupling, to avoid non-permissible pressure rise
inside the humidifier when the respirator is disconnected. This
means that in case the respirator is disconnected, the entire air
is freely released at the coupling. Therefore always disconnect
the humidifier from the belt unit and air supply hose (1) first, and
then, if necessary, the respirator from the humidifier (the belt unit
features a self-shut coupling which automatically interrupts the
air stream).
Attention:
All couplings are safety couplings. Therefore the nip-
ple must be pressed tight into the coupling for disconnection.
Simultaneously the sleeve must be shifted back. Since the outlet
coupling of the SATA top air is not self-shutting, for reasons
described above, always connect respirator first to the humidi-
fier, when putting the unit into operation, before the appliance
is connected to the regulation valve / belt unit. After this adjust,
as usual, the required air volume at the belt unit resp. regulation
valve. No further steps need to be taken at the humidifier itself.
4. Water Quality
To ensure sufficient life time of the humidifier module and to obtain
sufficient humidifying performance, use distilled water exclusively.
Attention:
In no case anesthetic or similar materials may be
filled into the humidifier. This also applies for distilled oils etc.,
since their effects in the breathing air may harm the equipment
wearer.
5. Safety Valve
The handle (8) features a built-in safety valve in order to prevent
destruction of the humidifier module by non-permissible pressure
rise. The safety valve in particular helps to prevent uncontrolled
pressure rise when the breathing air hose leading to the respira-
tor becomes kinked. It is set to maximum 3 bars (43 psi) which
is never exceeded. This pressure is sufficient for the operation
of all SATA respirators, and therefore for ensuring maximum air
supply.
Note:
If the safety valve is activated, check the air pressure in
the hose feeding the respirator, or the air hose leading to the res-
pirator for possible kinking. If necessary, remove kinks, replace
breathing air hose or reduce air feed pressure.
5. Pressure Release
As the threads of the humidifier module can be penetrated by
water, a small amount of air from the diaphragm inside will also
get into the water storage. In order to ensure this area is always
devoid of pressure when the humidifier has been disconnected,
the handle also features a built-in pressure release (11) which
helps to ventilate the water storage and to shift all air pressure
into the humidifier diaphragm area. Make sure the hose between
pressure release and nipple is never kinked.
Attention:
Always make sure the humidifier is in a vertical posi-
tion when being disconnected, to prevent water from the storage
from penetrating, by means of the pressure release function, into
the air passages of the system.
7. Changing the Water
Depending on the air flow, the water is usually used up after 3
hours of work. If warm water is filled in, the breathing air temper-
ature may be raised. However, never fill water with a temperature
of more than 60° C into the unit in order to avoid scalding or
similar problems, resp. damage to the unit. When the unit is not
in use for a long period of time (several days, etc.), it must be
emptied in order to prevent germ infestation, fouling of water, etc.
Make sure the different parts (humidifier module, etc.) can dry off
completely. If necessary blow-dry the pressure release unit from
the inside of the handle (8) by means of compressed air.
8. Changing the Humidifier Module
The humidifier module is to be changed every six months
in order to prevent germ infestation. It may be necessary to
change the humidifier module earlier if no distilled water is used,
or if the diaphragm threads are damaged. This damage can
be recognized by non-permissible water penetration into the
air hose leading to the respirator. For changing the humidifier
module unscrew the receptacle (7) from the handle (8) after the
appliance has been emptied completely, and pull the humidifier
