SR 700
USER INSTRUCTIONS

Particle filter fan unit SR 700

General information

The use of a respirator must be part of a respiratory protection program. For advice see EN 529:2005 or S/NZS 1715:2009. The guidance contained in these standards highlights important aspects of a respiratory protective device program but does not replace national or local regulations. If you feel uncertain about the selection and care of the equipment, consult your work supervisor or get in touch with the sales outlet. You are also welcome to get in touch with the Technical Service Department at Sundström Safety AB.

1.1 System description
The SR 700 is a battery-powered particle filter fan unit that, together with particle filter and head top – hood, visor, welding shield, helmet with visor, half-mask or a full-face mask – is included in the Sundström fan-assisted respiratory protective device systems conforming to EN 12941 or EN 12942 and to Sundström Powered Air Purifying Respirator (PAPR)system conforming to AS/NZS 1716:2012. The fan unit is to be equipped with filters, and the filtered air is supplied through a breathing hose to the head top. The above-atmospheric pressure then generated prevents pollutants from the surroundings from penetrating into the head top.  Before use, both these user instructions and those or the filter and head top must be carefully studied.

1.2 Applications
The SR 700 can be used as an alternative to filterrespirators in all situations for which these are recommended. This applies particularly to work that is hard, warm or of long- duration. When selecting filters and head top, the following are  some of the factors that must be taken into account:

• Types of pollutants
•  The possible occurrence of an explosive atmosphere
•  Concentrations
• Work intensity
•  Protection requirements in addition to respiratory protective device

The risk analysis should be carried by a person who has suitable training and experience in the area.

1.3 Warnings/limitations
Note that there can be national differences in the regulations for use of respiratory protective equipment.

Warnings
The equipment must not be used

• In the power-off state. In this abnormal situation, a rapid build-up of carbon dioxide and depletion of oxygen may occur in the head top and no protection is given.
•  If the surrounding air does not have a normal oxygen content.
•  If the pollutants are unknown.
• In environments that are immediately dangerous to life and health (IDLH).
•  With oxygen or oxygen-enriched air.
• If you find it difficult to breathe.
•  If you can smell or taste the pollutants.
• If you experience dizziness, nausea, or other discomforts.

Limitations

• The SR 700 must always be used with two-particle filters.
•  If the user is exposed to very high work intensity, negative pressure may occur in the head top during the inhalation phase, which may involve the risk of leakage into the head top.
• The protection factor may be reduced if the equipment is used in surroundings in which high wind speeds occur.
•  Be aware that the breathing hose might make a loop and get caught up by something in your surrounding.
•  Never lift or carry the equipment by the breathing hose.
• The filters must not be fitted directly to the head top.
•  Only use Sundström filters.
• The user should take care not to confuse the markings on a filter to standards other than

EN 12941 and EN 12942 with the classification of the SR 700 fan unit when used with this filter.

Warning system/alarm signals

• In the event of airflow obstructions
•  A pulsating sound signal will be heard.
•  The red warning triangle of the display will flash.

Action:
Immediately interrupt the work, leave the area, and inspect the equipment.

•  If the particle filters are clogged
•  A continuous sound signal will be heard for five seconds.
• The red warning triangle in the display will flash.

The warning triangle will flash continuously, whereas the sound signal will be repeated at intervals of 80 seconds.
Action: Immediately interrupt the work, leave the area and change the filter.

•  If the battery capacity is lower than 5 %
• A sound signal will be repeated twice at intervals of two seconds.
• The yellow battery symbol of the display will flash.

The battery symbol will flash continuously, whereas the other signals are repeated at intervals of 30seconds until about one minute remains before the battery would be fully discharged. The sound signal then changes to an intermittent signal.
Action: Immediately interrupt the work, leave the area, and change/charge the battery.

Start/Switch off

•  Start the fan by pressing the control button once. Fig. 23.
  The symbols on the display will light up and the sound signal will sound. The fan starts in normal operating status. Fig. 24.
•  Switch between normal and boosted operating status with the control button.
•  To switch off the fan unit, keep the control button depressed for about two seconds.

3.4 Performance check
The performance check should be checked on every occasion before the fan unit is used.

Check of the minimum flow – MMDF

• Check that the fan unit is complete, correctly mounted, thoroughly cleaned, and undamaged.
• Start the fan unit.
•  Place the head top in the flow meter.
• Grip the lower part of the bag to seal around the upper attachment of the breathing hose. Fig. 26.
  Note! You must not grip around the breathing hose itself as this would either obstruct the airflow or cause failure to achieve a proper seal. Fig 25.
• Grip the flow meter tube with the other hand so that the tube points vertically upwards from the bag. Fig. 26.
• Read the position of the ball in the tube. This should hover at a level with or slightly above the upper marking on the tube, (175 l/min). Fig. 27.

If the minimum flow is not achieved, check that – the flow meter is held upright, – the ball moves freely, – the bag seals well around the hose.

Checking the alarms
The equipment is designed to provide a warning if the airflow is obstructed.

•  Provoke an airflow stoppage by gripping the top part of the bag or by shutting off the flow meter outlet. Fig. 28.
•  The fan unit should then initiate alarms by sound and light signals.
•  If the air is again allowed to flow, the alarm signals will automatically cease after 10-15 seconds.

3.5 Donning

•  Take the fan unit on and adjust the belt so that the fan unit is firmly and comfortably secured at the back of your waist. Fig. 29.
•  Start the fan.
