AH Hose Assemblies Operating & Safety Instructions Issue 5.6 July 2015

1. Introduction

4. Servicing & Preventative Maintenance

The Oxylitre AH Series of Hose Assemblies have been designed specifically for most types of Medical Gas supply services and comply with BS EN 5359:2014 and European Directive 93/42/EEC.

Hose assemblies should be regularly inspected, cleaned and stored. It is important to inspect the condition of the hose tubing itself for any damage, as well as for any damage to probes, ferrules, outlets and terminal units. A regular inspection is recommended as part of a maintenance programme. However, if the hose assembly is attached to a mobile device such as a ventilator, where it could be dragged around, then it is recommended it be checked prior to use.

All hoses are colour coded according to British Standard and have gas specific fittings crimped to each end. Where the fitting are probes, NIST, DISS or terminals, the products comply with BS 5682:2015, BS EN 15908:2010, CGA V-5:2008 and BS EN ISO 9170-1: 2008 respectively. Colour coding: White Blue Black* Yellow Blue/White*† Grey

It is recommended that the hose assembly should be inspected and pressure tested by a Service Engineer on an annual basis as part of a maintenance programme. Fully qualified technicians/engineers only should carry out servicing. For service enquiries and information, please contact our sales office. NEVER USE FAULTY EQUIPMENT. If in doubt do not use assembly, and obtain a replacement.

Preventative maintenance ensures the safely of the patient and user . Note: Each assembly carries a 5 year manufacturers’ warranty.

†Longitudinal coloured stripes.

It is recommended that the full hose section of an assembly be replaced after 5 years service (in line with MDA/2003/007); this has the potential to extend operating life of the full assembly up to 10 years with regular servicing.

Hose assemblies are marked with manufacturing details of actual hose and carry details of date of assembly, serial number and additional product information.

5. Cleaning

*Assemblies also have white sleeving (other sleeves match hose colour).

2. Safety Warning: Safety precaution for prevention of fire & explosion Ensure that hoses are not allowed near any heat or ignition source, this is especially important where the product supplies Oxygen. Hose assemblies MUST NOT come into contact with any oil or grease for the same reason. When not in use, hose assemblies should be stored in a clean and dry environment within a temperature range of -10 to 40°C.

The hose assemblies require cleaning on external surfaces only by using a solution of luke-warm water and a mild detergent/disinfectant (read manufacturers instructions) and cleaning cloth. DO NOT autoclave. Dry immediately with a dry cloth. It is recommended that the assemblies are cleaned on a regular basis as part of a PPM programme. Avoid cleaning fluid from entering into any assembly orifices i.e. probes, outlets etc. DO NOT use any oil based cleaning fluids (note: soaps can be oil based).

3. Instructions for use On removal from packaging ensure that there is no damage to the assembly. Connect the hose fitting to the appropriate device or gas outlet/inlet. As indicated the fittings are gas specific and should only be connected to the correct source. It is the responsibility of the end user to ensure that the correct assembly is used for the purpose intended. Only persons with adequate training should use the hose assemblies, noting the large number of possible variants of hose and fittings available.
