 The Liquid Reservoir
To be kept in liquid form, the oxygen must stay very cold. Therefore, the liquid oxygen is stored in well insulated canisters, similar to a large thermos bottle. As the liquid oxygen warms, it increases the pressure inside the container. Since the contents are under pressure and constantly warming, the reservoir will need to vent some of its contents as the pressure inside increases. This natural venting prevents the unit from splitting and you may occasionally hear a hissing sound coming from the unit as it releases oxygen into the air. When the liquid oxygen leaves the container, it warms to room temperature and becomes a gas. One cubic inch of liquid oxygen will expand to 860 cubic inches of gas at normal atmospheric pressure. Never store oxygen equipment in a confined area such as a closet, cupboard or trunk of a car. This could cause an excess build-up of oxygen within the area and create a fire hazard. Never cover your liquid stationary unit or store anything on your reservoir.
Placement of a Stationary Reservoir
Work with your delivery technician to assess the residence and determine what will be the best location for the unit to be placed, based on your situation and lifestyle. The best location will be central to your primary living space and at least 10 feet away from all heat sources, as mentioned in the previous section. Also, keep in mind that your canister will need to be accessible for filling or exchange purposes as necessary.
Spillage
Keep the liquid unit upright at all times. If the unit falls on its side, it is possible that a stream of liquid oxygen could spill out of the unit. If a spill occurs, open the doors and windows, to vent the excess oxygen and call Wright & Filippis immediately at (800) 482-0222. Do not attempt to clean it up! Never move your liquid reservoir without consulting Wright & Filippis.
 Level Indicators
All models and sizes of liquid reservoirs have a contents indicator that shows how much liquid oxygen is in the container. To read your content level, simply press the indicator button on the top of the stationary unit and the lighted display will show the amount left in the container. On some units, there may be a content level gauge that will tell you how much is left in the reservoir. On these units, the pointer on the gauge will drop as the amount of liquid remaining in the tank decreases.
Call Wright & Filippis at (800) 482-0222 to order liquid oxygen before your reservoir is empty. Call to order liquid oxygen 48 hours before you need a delivery. Liquid oxygen deliveries are available Monday through Friday. A good rule is to call Wright & Filippis when your reservoir has 3 lights worth of liquid remaining.
