Overview
The Instruction Manual is used for JorVet J1550 ICU Unit. Installation, use, cleaning, maintenance
and repair of the ICU, as well as principles and functions of the product, caution and warnings,
common fault analysis and troubleshooting and after-sales services etc. are all in the Overview. Users
should operate the product in accordance with requirements as stated in the Instruction Manual. All
staff who use the equipment shall read the Instruction Manual carefully before turning on the
equipment. If you have difficulty in understanding the Manual, please contact a local JorVet product
distributor or the company for more detailed information.
JorVet ICU Unit is a newly developed pet ICU developed to serve an enormous need and fill a
vacancy in the domestic pet care industry. This moderately sized piece of pet medical equipment will
easily fit into most veterinarians’ practices and pet hospitals. Its characteristics and compact structural
design function perfectly to serve its purpose. The mechanism adopts "dual duct and double
circulation convective thermal regulation" to create an excellent and bacteria-free therapeutic
environment and young pet incubation environment similar to that provided by pet parent
(accompanied by purified air and proper temperature and humidity control).
The machine is equipped with an intelligent alarm device for five faults (sensor, extreme temperature,
excessive moisture, indoor oxygen concentration, lack-of-water in the tank and power supply
Interruption). This alarm system is tested and proven to be safe and reliable. Furthermore, it is
equipped with a unique cabinet structure and double-layer thermostat cover, which can prevent loss
of heat and radiant heat when nursing the pets. In addition, a temperature and humidity display device
is provided, measuring current temperature with the set temperature clearly visible. The heating
control adopts dual duct and double circulation convection heating technology. This prevents rapid
change in temperature minimizing the shock that can be caused. It ensures that temperature of the
ICU can rise evenly and gently. The Thermostat System adopts PID control technology, which can
solve the problem of inertia temperature error comprehensively, thus the temperature control is more
accurate and more energy efficient.

This External humidifier is helping the internal humidifier in our ICU to reach desired RH level more
easily, especially in extremely dry environment or under high temperature. The power plug should be
plugged into two flat pins receptacle at the rear left corner on the back of the ICU unit, it will be
regulated by the ICU motherboard with special programs installed. (Note: Do not confuse this socket
with another socket for nebulizer, which is next to this socket for humidifier.) Remove the lid of the air
inlet at the back of the ICU, expose the portal, and connect the flexible hose from this humidifier to
the ICU air inlet. The end with large diameter is to the back portal of ICU and the end with small
diameter it to the top portal of the humidifier.
After the unit is plugged into either ICU power supply outlet or wall mains, you can start the machine.
Rotate clockwise the controller to switch on the unit and the blue indicator lamp will be on.
The unit starts working. Rotate the controller knob to adjust the volume of the vapor. Fog can be seen
from the outlet port.
If a warm vapor is needed, press the button below the power button to switch between the default cool
mist mode and warm mist mode.
Remarks: the “warm mist mode” will be needed when the ICU unit is set at “high temperature + high
humidity”, like greater than 28℃+ 60%RH, the warm mist will definitely help humidifying more quickly.
Note：When LAC alarm can be seen on the humidity display panel, the external and internal
humidifiers will both stop working. Fill water in the internal water tank to the maximum level and both of
the humidifiers will start to work.
In certain cases, such as avian or other exotics, a desired environment of higher humidity and
temperature is preferred. In order to achieve these levels you must have increased temperature and
increased humidity. For instance, at 100F the humidity can not go beyond 50% relative humidity
without the external humidifier.
The external humidifier is not necessary when using the unit on standard mammalian patients like
canine and feline.

m minus which could reach deep respiratory system like alveolus and fine bronchus. The medicine is
nebulized evenly, no diluted needed, so there is no residues left almost and could achieve very high
medicine utilization rate. This device is preciously made medical equipment with very low faulty rate
and very good durability, could serve for 1000 -1500 hours as minimum lifespan.
Operation Instructions:
The nebulizer is easy to operate, please follow the simple steps as follows.
1. Install the nebulizer on the left side of ICU. Insert the power plug into the socket on the ICU.
2. Screw off the cup lid and nozzle; pour medicine liquid into the nebulizer cup.
3. Screw on the cup lid and nozzle, and put the nebulizer back.
4. Insert the nozzle of Nebulizer into the port. Turn on the nebulizer by pressing the switch on the
nebulizer. And then press Nebulize button on control panel of ICU to switch on nebulization, the
medical fog will be sprayed through grid and get into the ICU chamber. There are two stages of
nebulization treatment timing, in which the basic time is 10 minutes. Once the nebulization process
started, it is 10 minutes countdown automatically; pressing the "-" button on the nebulize adjustment
button will turn it into 20 minutes mode, pressing the "+" will turn back to 10 minutes mode. Pressing
Nebulize button again on the main control panel when the nebulizing process is running will switch the
nebulizer off.
a) The treatment process should not exceed 20 minutes for every nebulizing, misuse would possibly
cause Pulmonary edema.
b) To prevent superinfection, please pay close attention to the sterilization of nebulizer, ambient air and
all the related equipment, also disinfect animal mouth, nose and throat.
Mechanism of action
Animal respiratory system is an open system, where alveolus is the main air-exchanging place. The
object sprayed out of the nebulizer is mainly the mixture of oxygen and medicine – oxygen-medicine
aerosol. This kind of aerosol could improve oxygen metabolism and anoxic metabolism significantly;
increase the oxygen reserve in organisms. The cavitation effect of compressed air could disperse the
liquid medicine into gas phase and turn the liquid into fog form. The suspended particles will get deep
into animal respiratory system and treat the focus of infection directly. The feature of air compressing

Without being heated, high-frequency oscillation technology is adopted to product mist. Compared to
heating atomization, it can save 90% of energy. During atomization, large amounts of negative ions are
released, and have static electricity reaction with smoke and dust in the air, and cause precipitation.
According to the data released by World Health Organization, negative-ion is called “air vitamin”, and
an animal needs about 10 billion ecological negative-Ions every day, while our living environment can
only provide about 0.1-2 billion ones; when the negative-ion concentration in the air is up to 400
ones/cm³, it can satisfy our basic needs for survival; when the negative-ion concentration in the air is
up to 1000-2000 ones/cm³', it can satisfy our basic needs of health; when the negative-ion concentra-
tion in the air is up to 5000-10,000 ones/cm³, it can Improve our immunity and antibacterial ability; and
when the negative-ion concentration in the air is up to 300,000-500,000 ones/cm³, it can Improve our
natural healing ability, and many diseases can be healed without medication. Negative-ion plays a
significant role in improving the air quality of treatment room and improving and maintaining the health
of animals.
JorVet ICU Unit provides a high concentration of negative-ion generator, and the following is the
negative-ion test report:
Heating control adopts dual duct and double circulation convection heating technology to
allow temperature rising quickly, and temperature shock is small to ensure the temperature of the
ICU can raise evenly.

Tips:
a) There is hissing noise when nebulization starts, that’s generated from the high speed air flow. The
patented low noise air compressing technology ensures no vibration and no electronic noise when
nebulizer runs. The noise is much lower than normal level of most air compressor nebulizer, which is
around 85 decibels normally.
b) When nebulization is ON, the ventilation fans will be turned off to ensure good nebulizing effects,
and humidity and temperature control will be turned off too. The humidity alarm will Not be triggered in
nebulization mode, which will reset in 3 minutes after nebulization function turned off.
1. Mechanism of ICU
The air circulation system as shown in Figure 5.1.1 is driven by the circulating air of After being filtered
by the purifier, the air from the outside enters into the ICU, and "dual duct and double circulation
convection heating technology” is adopted to create an excellent and bacteria-free ICU therapeutic
environment and young pet incuba-tion environment. It provides clean air and proper temperature
and humidity.

reaction chamber design is adopted. Compared with similar products from abroad, the sterilization
strength increases by 18% - 27%.
---- Generally, the bactericidal action of ultraviolet ray on bacteria and viruses can achieve sterilization
rate of 99% - 99.9% in one to two seconds.
---- The broad-spectrum of ultraviolet sterilization is the highest, and it can efficiently kill almost all
bacteria and viruses.
---- The ultraviolet sterilizer has no secondary pollution. No chemicals will be added in ultraviolet
sterilization, thus, water and its surrounding environment will not be polluted secondly. Furthermore, it
will not change any ingredients in the water.
---- The operation of ultraviolet sterilizer is safe and reliable: traditional disinfection technologies such
as chloride or ozone, the disinfectants themselves are highly toxic and flammable substances, while
there is no such potential safety hazard in ultraviolet sterilization system.
JorVet ICU Unit is equipped with an external silent medical atomizer, and biomedical engineering
research shows: when the atomized particles are about 10 microns, medicines can only deposit in
the mouth and throat, when the atomized particles are about 3-6 microns, medicines can enter into the
bronchus, and when the atomized particles are less than 2 microns, medicines can enter into the finest
bronchus and alveoli. The JorVet J1550 ICU Unit can produce 0.5-4 micron atomized particles of
medicine. Meanwhile, intelligent control quantity of atomization is provided for your selection,
and the maximum atomizing volume is up to 0.5ml/min. The atomization in the ICU is even,
and the inhalation effect of atomized medicines is obvious. The medical atomizer is
characterized by low noise, which complies with pet ICU noise standard.
An increase in carbon dioxide concentration is accompanied by a decrease in oxygen concentration. Being
anoxic under low oxygen and high concentration of carbon dioxide for a long time will cause pulmonary
edema, cerebral edema, metabolic acidosis, electrolyte imbalance, shock, hypoxic encephalopathy, etc.
When the carbon dioxide concentration reaches 1000PPM above, it will cause dizziness, drowsiness and
reduced resistance to pets; when the carbon dioxide concentration reaches 2000-5000PPM, it will cause
mild nausea, poor breathing, rapid heartbeat and electrolyte imbalance to pets, and seriously affect the
health of pets and their postoperative rehabilitation; and when the carbon dioxide concentration is over
5000PPM, it will cause severe hypoxia, coma and even death.

The negative ion generator boosts low voltage to negative high voltage DC through the voltage
booster circuit. DC high voltage from the tip of carbon brush is used to produce high corona and
lots of high-speed electrons are released. Since electronics cannot exist in the air for a long time
(the life of existing electrons is n S level), they will be captured by oxygen molecules (O2) in the air
immediately, and then negative ions are formed; the working principle of which is the same as
natural phenomenon (negative ions are produced when there is thunder and lightning).
Test equipment: KEC-990 air ion concentration tester, HG3830 high voltage test bench

Cleaning and Maintenance

3. Complete Cleaning and Maintenance: remove and clean parts and assemblies periodically. Desired
results are achieved only by cleaning after removal.
Steps for Disassembling Components:
Remove four screws from the master control rack on the right to take down the right master control
rack, (remove the left master control rack in the same way). See fig. 8.3.1.
Remove power connection plugs on power cords on one side of the master control rack one by one.
Note that plugs have different colors for each electrical component.
Warning: do not remove control racks or electrical components from control racks immediately after
shut down; give it some time to cool down. The heaters in control racks reach high temperature.
Remove control racks or contact heaters after a 30 minutes respite after shutdown.
Remove four screws in the fan box and take out the whole heater. Clean the fan. Try not to remove heat
sinks from the fan, especially PTC heater bands that cannot be removed from heat sinks. See fig.
8.3.2.
Remove and clean filters behind the square plastic section inside the chamber.
Take out the humidifier. If it is working normally, it is not necessary to clean the humidifier. For separate
cleaning of the humidifier, it is not necessary to remove control racks. See the chapter of separate
cleaning of the humidifier above. If the humidifier is definitely damaged or does not work after separate
cleaning, remove the humidifier for cleaning and maintenance. (See fig. 8.3.3):
