Prior to putting the unit/spray gun into operation, read the
operating instructions completely and thoroughly. The stipula-
tions 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, modifi-
cation 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
DGUV-R 100-500 and DGUV-R 109-002 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 dia-
phragm module (3), the air becomes automatically saturated
with moisture. The purified and humidified breathing air is
ready to be supplied to a full face or half mask respirator, by
the outlet coupling (11). While air is passing through the SATA
breathing air humidifier top air, there is no pressure drop, resp.
no remarkable air loss. The water contained in the water stor-
age (4) automatically penetrates the diaphragm threads of the
humidifier module (3), always in a precisely sufficient quan-
tity 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
Before using the PPE breathing protection equipment, every
user is obliged to check the capacity of the air supply system,
possibly also in terms of the impact on other users of the sys-
tem.
The code "H" indicates that the compressed air feed tube is
heat-resistant. The code "S" indicates that the compressed air
feed tube is antistatic.
Before operation, the user must proceed with a risk assess-
ment regarding possible harmful components in the workplace,
e.g. nitrogen.
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
3 bar
(5), after removing the closing screw of the filling opening.
60° C
After this, wait for 20 minutes to allow the diaphragm threads
+4° C
to become saturated with water and reach their maximum
mechanical stability. In case the unit is put into operation too
130 ccm
early, without waiting time, the diaphragm threads may be
378 g
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 fill-
ing 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 discon-
nect 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
nipple must be pressed tight into the coupling for disconnec-
tion. 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 humidifier, 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 pre-
vent 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 respirator 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 ensur-
ing 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 respirator 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 dis-
connected, 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
position when being disconnected, to prevent water from the
storage from penetrating, by means of the pressure release
