Sundstrom SR 700 Instrucciones De Uso página 6

• 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.
WARNING - Immediately interrupt the work, leave
the area, and inspect the equipment. Do not
remove the SR 700 respiratory inlet covering while
you are in contaminated atmosphere.
If the battery capacity is low - the battery capacity has
dropped to about 5 % of the original charge, this is
indicated as follows:
• A sound signal will be repeated twice at intervals of
two seconds.
• The red battery symbol of the display will flash.
• The battery symbol will flash continuously, whereas
the sound signal is repeated at intervals of 30
seconds until about one minute remains before the
battery would be fully discharged. The sound signal
then changes to an intermittent signal.
WARNING - Immediately interrupt the work, leave
the area, and inspect the equipment. Do not
remove/doff the SR 700 respiratory inlet covering
while you are in contaminated atmosphere.
4.2 Belt
There are four (4) belt assemblies that can be used with
the SR 700 Fan Unit based on the material used in the
construction of the belt: rubber (SR 503), leather
(SR 504), PVC and nylon (SR 508). The belt consists of
two halves that can be fitted to the rear of the fan unit
without tools. To assemble proceed as follows:
• Place the fan upside down. Fig 4.
• Insert the three tongues of the belt half into the slot
in the fan. The folded end of the strap should face
upwards. Study the illustration carefully to ensure
that the belt will not end up upside down or back to
front. Fig 4.
• Press down the three lips locking the belt half. Fig.
• Proceed in the same way with other half of the belt.
• The length of the belt can easily be adjusted by
pulling in or slackening the strap ends.
4.3 Battery
There are one lithium-ion (Li-ion) battery 3.5 Ah
availiable for the SR 700 and are good for at least 500
charging cycles. One battery is required to operate the
SR 700 Fan Unit. The charging time is 3 hours. The
fan operating time is up to 8 hours.
New batteries must be charged before they are used
for the first time. The battery need not be discharged
before it is charged. Remove the battery from the fan
unit and remove the protective tape. Charge the battery
indoors at room temperature. To charge the battery
proceed as follows:
• The battery cover locks the battery. Press down the
cover and and withdraw the battery. Fig. 3.
• Check that the mains voltage is between 100 V and
240 V.
• Connect the battery to the battery charger. Fig. 2.
The charger carries out charging automatically in three
stages:
6
1. Yellow LED - The battery is being charged at
constant, maximum charging current up to
approximately 80% of battery capacity.
2. Yellow flash LED - The battery is being charged to
full capacity at constant voltage and gradually
decreasing charging current.
3. Green LED - The battery is fully charged and the
charging current is switched off.
• When charging has been completed, pull the plug
out of the socket before separating the battery from
the charger.
• Push the battery back into the battery
compart¬ment. Check that the battery has been
pushed in as far as it will go and that its lock is
operative.
Storage
After cleaning, store the equipment in a dry and clean
place at room temperature. Avoid exposing it to direct
sunlight. A cool well-ventilated area in the temperature
range of 50 to 77ºF (10 to 25ºC) [at a relatively humidity
less than 70%] is ideal to minimize degradation while in
storage. Batteries in storage do not retain their full
charge indefinitely. Sundström recommends that
batteries not in use be charged at least every 6 months.
When not in use do not store the SR 700 Fun Unit with
the battery installed. Leave the battery connected to
the Sundström charger. Store the battery separated
from the SR 700 Fan Unit.
WARNING: If the battery shorts or overheats it can
cause a fire, venting of gas or fumes, or leakage of
electrolyte that can cause personal injury.
Performance & Conditioning (charging and
recharging)
The SR 700 Fan Unit can provide up to 8 hours of
operating time.
The NIOSH laboratory performance service life
(breathing machine operating at a rate of 24 respira-
tions per minute, minute volume of 40 l/m for a period
of 4 hours) is not guaranteed in real situations. The
5.
actual service life of a PAPR will depend on the charge
of the battery, condition of the battery (batteries
degrade over their lifetime), battery operating
temperature, workload of the user (breathing rate of
variable speed PAPR) or resistance to air flow
associated with clogging of the filtering components,
prolonged periods of operation, etc.
For best performance of the SR 700 Fan Unit charge
the battery immediately after each use. The Li-ion
rechargeable battery should not be completely
discharged. Batteries in poor condition could cause the
"low battery warning" time to be reduced or the PAPR
air flow to decrease rapidly.
WARNING: There is no field maintenance on Li-ion
batteries. Do not attempt to disassemble or repair
a damaged battery. This may result in serious
bodily injury or death.
Shelf Life & Disposal
The SR 700 system has a shelf life of 5 years from the
date of manufacture. However, note that the battery
must be charged at least every 6 months.
The battery should be removed from the fan unit and
sorted as battery waste.
