EXECUTION
EXAMINATION
Do not begin installation until the substrates have been properly constructed and prepared.
If substrate preparation is the responsibility of another installer, notify Architect in writing of unsatisfactory preparation before proceeding.
PREPARATION
Clean surfaces thoroughly prior to installation.
Cleaning of Medical Gas Tubing: If manufacturer-cleaned and -capped fittings or tubing is not available or if precleaned fittings or tubing must be recleaned because of exposure, have supplier or separate agency acceptable to authorities having jurisdiction perform the following procedures:
Clean medical gas tube and fittings, valves, gauges, and other components of oil, grease, and other readily oxidizable materials as required for oxygen service in accordance with CGA G-4.1.
Wash medical gas tubing and components in hot, alkaline-cleaner-water solution of sodium carbonate or trisodium phosphate in proportion of 1 lbs (0.453 kg) of chemical to 3 gal. (11.3 L) of water.
Scrub to ensure complete cleaning.
Rinse with clean, hot water to remove cleaning solution.
Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
INSTALLATION

Install flexible, corrugated medical tubing with polyethylene jacket in accordance with manufacturer's written instructions.
Corrugated medical tubing is allowed to be installed below grade or in slab when encased in a non-metallic watertight conduit with long sweep bends.
Install tubing using only components manufactured by tubing manufacturer.
Make tubing joints using only tools and fittings specified by tubing manufacturer.
Maintain caps and plugs at tubing ends until ready to apply fittings to make joints.
Do not bend tubing to a radius smaller than the minimum bend radius specified.
Support tubing in accordance with manufacturer's written instructions, with maximum support spacing as specified in PART 2.
Comply with requirements for seismic-restraint devices specified in Section 22 05 48 - Vibration and Seismic Controls for Plumbing Piping and Equipment.

The Contractor is to perform tests and inspections.
Engage a factory-authorized service representative to test and inspect components, assemblies, and equipment installations, including connections.
Tests and Inspections:
Piping Leak Tests for Specialty Gas Piping: Test new and modified parts of existing piping.
Cap and fill specialty gas piping with oil-free, dry nitrogen to pressure of 50 psig (345 kPa) above system operating pressure, but not less than 150 psig (1035 kPa).
Isolate test source and let stand for four hours to equalize temperature.
Refill system, if required, to test pressure; hold for two hours with no drop in pressure.
Repair leaks and retest until no leaks exist.
Inspect specialty gas regulators for proper operation.
** NOTE TO SPECIFIER ** See Section 014000 'Quality Requirements' for retesting and reinspecting requirements and Section 017300 'Execution' for requirements for correcting the Work.
Piping will be considered defective if it does not pass tests and inspections.
Prepare test and inspection reports.
CLEANING AND PROTECTION
Protect tubing from damage.
Retain sealing plugs in tubing, fittings, and specialties until installation.
Clean tubing not properly sealed, and where sealing is damaged, in accordance with "Preparation" Article.
Touch-up, repair or replace damaged products before Substantial Completion.
