PIPES AND PIPE FITTINGS
I F. Refrigeration System Piping: If, for any reason, sanitized and sealed -at- the -mill tubing is not used,
clean the tubing as follows:
1. Wipe each tube internally with a dry, lintless cloth followed with a clean lintless cloth
I
saturated with recommended refrigerant.
2. Repeat until the saturated cloth is not discolored by dirt.
3. Wipe with a clean cloth saturated with compressor oil and squeezed dry.
4. Wipe with a dry, lintless cloth.
1 3.09 TEST
A. General:
I 1. Minimum duration of two hours or longer, as directed for all tests. Furnish report of test
observation signed by qualified inspector. Make all tests before applying insulation,
backfilling, or otherwise concealing piping or connecting fixtures or equipment. Where
part of the system must be tested to avoid concealment before the entire system is
I complete, test that portion separately, same as for entire system.
2. Provide all necessary temporary equipment for testing, including pump and gauges.
Remove control devices before testing and do not use piping system valves to isolate
sections where test pressure exceeds valve pressure rating. Fill each section with water
I 3. and pressurize for the indicated pressure and time.
Observe each test section for leakage at end of test period. Test fails if leakage is
observed or if pressure drop exceeds 5% of test pressure.
I B. Repair: .
1. Repair piping system sections which fail the required piping test by disassembly and re-
installation, using new materials to the extent required to overcome leakage. Do not use
chemical stop -leak compounds, solder, mastics, or other temporary repair methods.
2. Drain test water from piping systems after testing and repair work has been completed.
I C. Sewer: Furnish all facilities and personnel for conducting the test. Test in accord with the
requirements of the State Plumbing Inspector and local authorities.
D. Plumbing Waste and Vent Piping: Hydrostatic test by filling to highest point, but not less than 10'
water column on major horizontal portion.
E. Water Piping: Hydrostatic pressure of 100 psig without loss for four hours.
I F. Natural Gas Piping: One half hour minimum air at 60 psig for 2 psig gas, and 15 minutes at 10
psig for 7" water gauge natural gas or as approved and certified by serving utility.
I G. Heating Water Piping: 75 psig hydrostatic for 30 psig systems without loss for four hours.
H. Tanks and Equipment: Hydrostatic pressure to 1.5 times operating pressure.
I. Refrigerant System:
1. When the refrigerant connections have been completed, close the compressor suction and
discharge valves (or receiver outlet valve in the case of condensing unit) and test the
balance of the system to near operating pressure with a dry nitrogen.
I 2. Carefully test all joints, using soap and water or other sudsing solution. After all joints
are tested, discharge the gas and repair all leaks, then repeat the test with a mixture of
nitrogen and HCFC -22 and a halide torch or an electronic leak detector.
3. Evacuate the system to remove moisture and non - condensables. Lower the absolute
I pressure with a vacuum pump to 1000 microns of mercury. Apply external heat as
required to vaporize moisture.
4. Dehydrate each refrigerant circuit by satisfactory use of a vacuum pump before charging
with refrigerant. Furnish all necessary refrigerant and oil for complete operating charge
I of the system. Upon completion of the work of construction, test all refrigeration
equipment under normal operating conditions and leave in operating order. Adjust
automatic temperature controls.
5. After the first 24 hours of operation, measure the pressure drop across the suction filter.
I If the pressure drop exceeds 5 pounds per square inch, replace the cartridge with a new
one, retesting and replacing the cartridge and/or adjusting the system as necessary to
achieve a pressure drop of less than 5 pounds per square inch in 24 hours.
