"Camel" Liquid Ring Medical Vacuum Medical Systems 1. Installation 1.1 Uncrating Upon delivery, the condition of the LifeLine "Camel" Medical Vacuum System should be carefully inspected. Any indication of damage by the carrier should be noted on the delivery receipt, especially if the system will not be immediately uncrated and installed. -
Page 5: Locations Above Sea Level
"Camel" Liquid Ring Medical Vacuum Medical Systems 1.3 Locations Above Sea Level The safety relief valves and vacuum control switches on the Lifeline “Camel” Vacuum systems are factory set for an altitude less than or equal to 2000 ft. However, if the altitude is greater than 2000 ft, certain adjustments may be necessary to compensate for a lower barometric pressure. -
Page 6: Piping
"Camel" Liquid Ring Medical Vacuum Medical Systems 1.5 Piping Connect piping to the system so that no strain is applied at the point of connection. Pipe strain on vacuum pump castings may cause hard-to-trace troubles after the system is in operation. Support inlet and discharge piping near the system. - Page 7 "Camel" Liquid Ring Medical Vacuum Medical Systems 1.5.4 Exhaust Piping Connect pipe to the air discharge connection on the Camel reservoir. This exhaust line must be piped outside of the building in accordance with NFPA 99. To ensure that no restriction of airflow will occur, size the piping according to the following chart.

Page 12: General Operation
"Camel" Liquid Ring Medical Vacuum Medical Systems 3. General Operation 3.1 How the Vacuum System Works (See Figures 3-1-1 & 3-1-2) The BeaconMedæs "Camel" Liquid Ring Medical Vacuum System works basically like other vacuum systems with the air from the system piping (vacuum system inlet) being drawn through the vacuum control tank, then through the inlet check valve, and finally into the inlet of the vacuum pump. - Page 13 "Camel" Liquid Ring Medical Vacuum Medical Systems 3.1.4 Camel Reservoir Tank The Camel reservoir has three specific functions. It separates the air and water discharge from the vacuum pumps by means of a specially designed muffler/baffle system. It reclaims discharge water and holds it for use as re- circulated seal water.
-
Page 14: Relief Valve
"Camel" Liquid Ring Medical Vacuum Medical Systems Minimum Run Timer(s) All LifeLine "Camel" vacuum systems incorporate minimum run timers to minimize the starts and stops on the vacuum pumps. For multiplex systems, there is a minimum run timer built into the PLC for each pump, but they all have the same time value. -
Page 15: Vacuum Check Valve
"Camel" Liquid Ring Medical Vacuum Medical Systems 3.6 Vacuum Check Valve Vacuum check valves are designed and engineered for the unique problems of the vacuum field. Featuring extremely low pressure drop, they open on less than 1/10” W.C. Special design permits a lightweight, stamped stainless steel disc to open fully, providing full flow with minimum resistance. -

Page 46: Disassembly And Re-Assembly
"Camel" Liquid Ring Medical Vacuum Medical Systems B.6 Disassembly and Re-Assembly B.6.1 Before Disassembling The vacuum pump operates most efficiently when the rotor-to-head clearance is the same as that set by the factory. Continued use over a long period of time may cause this internal clearance to change. If pump operation indicates that trouble has developed, it may be necessary to dismantle the pump to inspect for readjustment of this clearance. - Page 47 "Camel" Liquid Ring Medical Vacuum Medical Systems Before disassembling the pump the following must be done: 1. Isolate, lock, and tag-out all sources of electrical input. 2. Isolate, drain and bleed the pump and piping. 3. Disconnect the suction, discharge, and service liquid lines. B.6.2.1 Disassembly Procedure To disassemble the vacuum pump: Disconnect piping from air inlet and discharge and the liquid compressant inlet ports.
