spread in uniform layers in such a manner as to fill the trench completely so that there will be no unfilled spaces under or about rocks or lumps of earth in the back-fill. Large or sharp rocks, frozen clods and other debris greater than 3 in. (76,2 mm) in diameter should be removed. Rolling equipment or heavy tampers should only be used to consolidate the final back-fill.
Outdoor Installations
TYCO CPVC Pipe and Fittings are not listed for outdoor applications other than underground.
FACTORY MUTUAL (FM) 2
TYCO CPVC Pipe and Fittings are FM Approved for use in:
• Miscellaneous non-manufacturing occupancies as described in FM Loss Prevention Data Sheet 3-26, “Fire Protection Water Demand for Non- storage Sprinklered Properties”, Table 2, Section L.
• Residential occupancies as described in FM Loss Prevention Data Sheet 3-26, “Installation of Sprinkler Systems”.
TYCO Fire Sprinkler Systems shall be employed in wet pipe systems only. (A wet pipe system contains water or water and glycerin [anti-freeze solution] and is connected to a water supply so that the water or water and glycerin [anti-freeze solution] will discharge immediately when the sprinkler is opened.)
Concealed Installations (FM)
In accordance with the FM Approval, protection shall be provided for TYCO CPVC Pipe and Fittings as follows:
• The minimum protection shall consist of either a permanently installed noncombustible barrier from any area protected by the system.
Note: A permanently installed barrier is one that cannot be removed without substantial cosmetic damage. Drop ceiling tiles, as used in sus- pended ceilings are specifically considered not be permanently installed for the purposes of this definition. Noncombustible is defined as having a minimum finish fire rating of 15 minutes when tested per ASTM E119.
• As an alternative to the protection of a permanently installed noncombustible barrier, FM has approved the use of TYCO CPVC with the SOFFI-STEELTM covering system manufactured by Grice Engineering.
• FM Approved quick response, standard or extended coverage, or FM Approved residential sprinklers installed in accordance with their approval limitations may be used.
• Solvent cement joints shall be made with TFP-500 or TFP-600 One Step Solvent Cement.
Exposed Installations - Smooth, Flat, Horizontal Ceilings (FM)
