How to connect, air, electrical and breathing circuit to the Mallard 2800

The Mallard 2800 is a highly advanced machine used for medical purposes, specifically for providing oxygen and other gases to the patient. It is crucial that the air hose, electrical, and breathing circuit connections are made properly for the machine to function optimally. In this guide, we will take a detailed look at the steps involved in making these connections and provide you with all the information you need to get started.

Step 1: Before connecting the hose to the ventilator, it is very important to make sure that the house gas or tank gas pressure is regulated down to about 80 PSI. You are now ready to connect the Mallard 2800 to the incoming air supply. The air hose is approximately 20 feet long and must be close enough to your source of oxygen or gas that you plan to use. To make the connection, you will need a 5/8” open end wrench and an 11/16th-inch open end wrench. Once you have the air hose connected to your air source, you can then proceed to the next step.

Step 2: Once the air hose is connected to the cart, you can adjust the pressure settings on the machine. The Mallard 2800 comes with a gage on the back of the cart frame where you can check the gas pressure coming into the system. The minimum recommended pressure coming into the machine is 60 PSI. Once connected to the supply air or gas, you can regulate the pressure you want to work with by turning the black flow control knob on the front of the control box. Caution: Once the needle on the gage next to the black knob stops moving, do not keep turning the knob or it could damage the black flow control regulator. If you need more pressure, you will have to first raise the incoming gas to the cart.

Step 3: Electrical Connection: The next step is to connect the electrical cord. The cord is located on the back of the machine and is wrapped onto the cart for storage. To connect it, simply unwrap the cord and plug it into a 120-volt line. The control box on the Mallard 2800 can handle either 120 or 220 volts and will automatically switch over for you. In some geographic locations you may need an adapter for the 220-volt power source.

Step 4: Breathing Circuit Connection: The breathing circuit consists of two hoses that connect to the absorber inspiratory and expiratory pipes. You will need to do an up and down motion while pushing the hoses onto the two stainless pipes. The hoses should be pushed on about an inch and a half and you will feel when they are in place because the pipes will click. It is advised to back off slightly so that the pipes don’t touch. If you have a newer machine, it may require more force to make the connection.

Conclusion: In conclusion, connecting the air hose, electrical, and breathing circuit to the Mallard 2800 is a crucial step in ensuring that the machine functions optimally. By following these simple steps, you can make these connections quickly and efficiently. If you encounter any difficulties or have any questions, consult the user manual, or reach out to a qualified technician for assistance. With this comprehensive guide, you are well on your way to making the most of your Mallard 2800 machine.
