2-System Safety
2.1 Safety Instructions
For safety, please pay attention to the following items:
Please read the user’s manual carefully.
Operating conditions of R419 Smart Veterinary Ventilator:
Temperature: 0℃～ +40℃, humidity:15%~95% (non-
condensing),atmospheric pressure: 70kPa ～ 110kPa
Storage conditions of R419 Smart Veterinary Ventilator:
Temperature: -20℃～ +45℃, relative humidity : ≤95%, atmospheric pressure:
70kPa ～ 110kPa
Warning:
When high pressure oxygen meets combustible materials (lubricating grease, motor oil,
alcohol, etc.), it may cause an explosion:
Keep the equipment and all connections absolutely free of oil and grease.
It is strictly forbidden to smoke near the ventilator and/or ignite an open flame.
When installing and replacing the oxygen cylinder, use your hand as much as possible
to tighten all the connections on the oxygen cylinder and pressure relief valve. If you
need to use tools, do not use excessive force, it may cause damage to the threads and
sealing materials and may result in gas leakage.
Take measures to prevent the oxygen cylinder from tipping over. If the oxygen
cylinder falls over, the pressure relief valve may be damaged and cause an explosion.
Important:
Always open the pressure relief valve on the oxygen cylinder slowly to prevent
the surge of pressure from impacting the valve fittings inside the ventilator.
Always check the pressure of the oxygen cylinder. Do not completely exhaust the
oxygen in it, humidity in the surrounding air may invade it and cause parts to rust.
Attention:
Animals and the ventilator must be continuously observed during use.
The breathing circuit interconnected with the anesthesia machine needs to be
remain unobstructed and easy to observe. Avoid operations that may result in
covering or affecting their function (e.g. improper location of the animal).
A large number of quality assurance measures have been taken in the
development of the equipment software, and the risk due to software defects is
minimal.
Take measures to protect the rubber components from ultraviolet light and
prolonged direct sunlight, to avoid embrittlement of these parts.
2.2 Cautions
Before operating this equipment, the operator should meticulously read this user’s manual
and fully understand its contents.
Before using this equipment, please carefully check all connectors to ensure adequate

5
gas-tightness and to avoid any leakage.
Equipment malfunctions caused by improper cleaning, maintenance or operation will
be considered the user’s responsibility.
If someone disassembles the equipment’s main body without authorization, RWD shall stop
providing any quality assurance or technical maintenance service to this equipment. If the
user has any technical questions, please contact the authorized person or the RWD for
support.
Risk of electric shock: Laypeople are prohibited from removing the cover or panel of the equipment and
removing the built-in rechargeable battery.
DANGER: The use of flammable or explosive gases as a gas source for the equipment is prohibited.
2.3 Safety Instructions
The use of this equipment is limited to persons with relevant expertise in respiration and
anaesthesia or persons trained by the manufacturer.
Keep the equipment away from water, with good ventilation and relatively consistent air pressure,
temperature and humidity. It should not be exposed to direct sunlight or places with gases or chemicals
that are corrosive, flammable or explosive. During placement or handling of the equipment, operators
should prevent the equipment from being inclined, vibrated or squeezed.. Pay attention to the voltage,
current and frequency of the connected power source, and make sure that the grounding terminal is
normal. Avoid overloading the equipment.
Warning！！！
The R419 Smart Veterinary Ventilator should self-calibrate when started. If self-calibration
cannot be done, it means there may be some kind of circuit breakdown or internal pipe leakage. In
that case the user should turn off the equipment power and make sure the gas source pressure is
between 41-87 psi, the breathing circuit connection is correct, and the flow rate of the anesthesia
machine is appropriate (note that the breathing circuit is connected to the breathing bag at this time,
and the evaporating tank of the anesthesia machine is closed). Then, turn on the equipment for self-
calibration after the folded bag in the bellows of the ventilator rises to the top of the bellows. If
self-calibration fails again, please contact your supplier or the RWD after-sales service department
for further support.
2.4 Warranty
The warranty of this equipment starts from the day it leaves the factory. If the equipment cannot
be used normally due to problems such as materials and/or process defects, the company
undertakes after-sales service such as maintenance and/or part replacement.
Warning!
It is forbidden to use the oxygen flush button on the anesthesia machine
during the inspiration phase of the breathing cycle. It may cause severe lung
rupture in the animal. During the inspiration phase, the drain valve in the control
unit is closed, so the oxygen flow is added to the breathing machine's air supply
flow, and the only direction of the airflow is to the lungs of the experimental
animal.

Any damage caused by improper use is not covered by the warranty. If repair or replacement
of parts is required, the cost will be borne by the user.
If the equipment that has been returned for repair has been dismantled without the
authorization of RWD before arriving at RWD, the company does not provide after-sales
service such as warranty, free maintenance or parts replacement.
The warranty statement (including its restrictions) is exclusively issued by RWD and covers
all other warranties.
