Breathable air
The breathable air shall conform to at least the following purity requirements:
• the pollutants shall be maintained at a minimum and must never exceed the hygienic limit value
• the content of mineral oil must be so low that the air has no oil smell (the threshold of smell is around 0.3
mg/m3)
• the air shall have a sufficiently low dew point to avoid internal freezing of the equipment.
In the event of uncertainty as to whether the above demands have been met, a filter such as the Sundström
type SR 99-1 compressed air filter should be connected.

1. Functional check
2020-06-04
OI03H-0318 SR 63 5
1.1 On every occasion before
the hood is used, check that
the air flow - measured in the
hood - is at least 150 l/min:
Connect the breathing hose
of the facepiece to the control
valve.
1.2 Connect the compressed
air supply tube to the control
valve.
Turn the control valve knob
anti-clockwise as far as it will
go, in order to throttle the air
flow rate to a minimum.
1.3 Place the hood in the bag
and grip the opening of the
bag so that it seals around
the breathing hose.
Grip the flow meter with the
other hand and hold it so that
it points vertically up from the
bag. Read the position of the
ball in the tube. It should float
level with or just above the
marking on the tube.
If the flow rate is below the
minimum value, check that
• The flow meter is vertical.
• The float can move freely.
• The air supply is not
restricted by kinks or other
restrictions in the hoses.

2. Donning
2020-06-04
OI03H-0318 SR 63 6
2.1 Put the belt on and adjust
the length.
Arrange the control valve in a
way that allows easy
adjustment of the flow rate
and a strict watch over the
breathing hose, i. e. it must
not be placed on the back of
the waist.
2.2 Connect the breathing
hose of the hood to the outlet
of the control valve.
Unroll the compressed air
tube and make sure that it is
not twisted.
Connect the tube to the
control valve inlet.
2.3 The hood is now being
supplied with air, and you can
put it on. If necessary, the
width and height of the head
harness can now be adjusted.
Adjust the neck width of the
hood by means of the elastic
neck strap.
2.4 Use the control valve knob
to set the air flow rate to suit
the work intensity. In the fully
closed position (turn anti-
clockwise), the flow is around
150 l/min, while in the fully
open position (turn clockwise),
it is around 240 l/min.

3. Head harness adjustment
2020-06-04
OI03H-0318 SR 63 7
3.1 The width and height can
be adjusted with the head
harness in place in the hood.
To adjust the width: use the
knob in the rear part of the
head harness to adjust the
width. Turn the knob
clockwise to reduce the width
and anti-clockwise to
increase it.
3.2 To adjust the height:
the head strap of the head
harness consists of two
halves. The upper half runs in
a groove in the lower half.
The position is determined by
means of a pin in the lower
half that engages in one of
the holes in the upper half

4. Doffing
2020-06-04
OI03H-0318 SR 63 8
4.1 Leave the work area
before taking the hood off.
Release the neck strap by
releasing the buckle. Grip the
top part of the hood with both
hands and pull the hood
upwards/forward.
4.2 In emergency situations,
the neck strap can be
released without releasing the
buckle:
Grip the neck strap with one
hand on each side of the
buckle and pull firmly.
4.3 Releasing the
compressed air tube /
breathing hose Both
couplings are of safety type
and are released in two
stages.
Push the coupling towards
the nipple.
4.4 Pull the locking ring back.

5. Change the visor/frame
2020-06-04
OI03H-0318 SR 63 9
5.1 Release the head
harness which is secured by
means of two socket-head
screws at the top corners of
the frame.
5.2 Pull off the 8 rubber studs
and remove the frame and
visor.
5.3 Straighten the frame or fit
a new frame and place it on a
flat surface with the short side
towards you. Fit 4 studs into
the two furthest holes on
each side.
5.4 Place the hood over the
frame and insert the 4 studs
into the corresponding holes
in the hood.

5. Change the visor/frame
2020-06-04
OI03H-0318 SR 63 10
5.5 Remove the protective
films from the visor and from
the double-sided adhesive
tape.
5.6 Fit the visor, with the tape
facing downwards, over the
rubber studs. Bear in mind
that the holes for the head
harness screws must be
oriented in the same direction
as the hood and frame.
Secure with the studs,
possibly using a pair of pliers.
5.7 Bend the frame to the
required shape.Align the
vacant holes for the studs in
the frame, hood and visor.
Insert the studs and secure
them by pulling the studs
from the inside of the hood.
The simplest procedure is to
fit one stud at a time.
5.8 Press the visor towards
the frame all round, so that
the tape will stick to the hood
material. Fit the head
harness. Make sure that the
beads in the mounting plate
of the head harness are
oriented into the guide holes
in the visor.

6.Change the breathing hose
2020-06-04
OI03H-0318 SR 63 11
6.1 Release the hose from
the control valve
6.2 Release the hose from
the hood by cutting off the
hose clip with a pair of
nippers
6.3 Thread the hose clip
supplied onto the new hose
and connect the hose to the
hose nipple of the hood.
Secure the hose clip by
means of the pincers.
6.4 By pulling the hose, check
that it is firmly secured to the
hood.
