R1600V Series Medical Regulators Operating & Safety Instructions Issue No 1.4 Date Sept 2012

1. Introduction The Oxylitre R1600V Series Regulator has been designed specifically for medical use and are available for use with Oxygen, Air, Entonox, Nitrous Oxide, Carbon Dioxide and Helium. Conforms to BS EN ISO 10524-1.

2. Specifications Inlet Connection All gas connections comply with National and International Standards for safety and prevention of connecting an incorrect gas (BS 341-3 for Bull Nose; BS EN ISO 407 for Pin Index). Optional Outlet Connectors The R1600V Series Regulators are available with or without a 0 - 15, 0 - 12 or 0 - 3 LPM Flowmeter (depending on gas selection). Units are also available with a gas specific (Quick Release) Self Sealing Valve or a threaded outlet connection. Outlet Pressure The R1600 Series Regulators are preset to 4 Bar (400 kPa), except for MA-7 units that are set to 7 Bar. Filters (Please Note: Filters should only be replaced by authorised/trained Personnel). Each Regulator is fitted with two integral filters that will protect the patient and/or the user from any foreign matter. 1. The first Filter is placed in the inlet stem of the Regulator. 2. The second filter is placed at the Regulators’ output in the Self Sealing Valve/Flowmeter. Gauges Each Regulator is fitted with an easy to read, colour coded Contents Gauge. Safety Valve The Safety Valve System has been designed to release gas pressure for the safety of the user/patient and/or the equipment connected to the Regulator. This will operate only if the working pressure increases due to a malfunction in the Regulator (the Safety Valve System is not an adjustable device).

3. Instructions for use Fitting to a Cylinder (Note: Take great care with these operations): Before connecting a Regulator to a Cylinder, momentarily open and close the Cylinder Valve to blow out any accumulated dust or moisture. Inspect the inlet connector seal for signs of damage or contamination, if found replace immediately! These seals should be replaced at least once a year i.e. as part of a Standard Service (Note: NEVER use two seals together). Seal for Pin Index Inlet Connectors = Part No: OX010 (BODOK) Seal for Bull Nose Inlet Connectors = Part No: BS110 (‘O’ Ring) Connect the Regulator securely to the Cylinder. Open the Valve very slowly (approximately one full turn) to reduce the danger of explosion or fire arising from pressure shock. Check the contents of the Cylinder, if or when the Gauge Indicator Needle points in the red section on the Gauge (below ¼ full), replace the Cylinder. Using the Flowmeter (if fitted). Before use, ensure that the correct sized Mask/Nasal Cannula and Connecting Tube is used. Oxylitre Recommendations: Mask: IS1106/1140; Connecting Tube: IS1174; Nasal Cannula IS1161. Connect the Connecting Tube to the Mask/Nasal Cannula and connect the other end of the tube to the Multi-sized Tubing Outlet on the Flowmeter. The Mask or Nasal Cannula can now be placed on the patient.

Rotate the Flowmeter Control Knob anti-clockwise until the required Litre flow for therapy administration has been selected. The Litre Flow is indicated on the Flowmeter Inner Tube. Always check the contents of the Cylinder indicated by the Contents Gauge. When the user/patient has finished, rotate the Control Knob clockwise to shut off the gas. Removing from a Cylinder a. Turn OFF the cylinder valve. b. Bleed off the pressure, by opening a valve on the apparatus connected to the regulator (or if a Flow-metering Device is fitted, turn the Flow Control Knob to a Flow Selection). c. When the indicator on the Contents Gauge has fully dropped, disconnect from the Cylinder SLOWLY.

4. Safety Precautions for the prevention of Fire & Explosion The Regulator or patient MUST NOT be allowed near any source of ignition i.e.: Cigarette/cigar/pipe smokers Sparks Naked flame Open electrical appliances This precaution applies during and after patient use. Warning: This Regulator MUST NOT come into contact with any Oil or Grease, a reaction may cause an Explosion/Fire.

5. Maintenance A medical regulator forms part of an essential support system. Regulators must be treated with care and be serviced on a regular basis, (i.e. preventative maintenance) to ensure the unit’s reliability and quality for the purpose that it is used for. The units require cleaning on external surfaces only by using a solution of luke-warm water and “Dettol” or similar disinfectant fluid (read disinfectant instructions) and cleaning cloth. Inspection Recommended at least annually by a Service Engineer and consist of: a. Connect regulator to the cylinder (as in section 3) b. Check the contents of the cylinder that is indicated by the pressure gauge. c. Close the cylinder valve and observe the contents gauge for pressure drop. If the needle on the gauge drops, this indicates a leakage in the system. The device will require a service and/or repair. Service/Repair Servicing should be only carried out by fully qualified technicians. A Major Service is recommended every 5 years. For service enquiries and information, please contact our sales office. NEVER USE FAULTY EQUIPMENT. Preventative maintenance ensures safety for the patient and user.

6. Technical Data Specifications a. Maximum Inlet Pressure: 2000 psi (138 Bar). b. Minimum Inlet Pressure: 500 psi (34.5 Bar). c. Output Pressure: 58 psi (4 Bar). Tolerance: ± 3 psi. d. Flow Rates: See graph on the next page. e. Standard Discharge: 125 LPM. Please see Table 1 for the Regulators performance specifications. This indicates the performance of the device set at the standard output pressure and discharges at varied inlet pressures. Please see Table 2 for the Regulators’ Pressure characteristics when the Flowmeter is in operation. Page 2
