3 ft (0.9 m).
2.3.5 FOG disposal systems and covers for installation in traffic areas shall be designed to withstand an AASHT() H20-44 wheel load, an additional 3 ft (0.9 m) earth load with an assumed soil weight of l0() psf (4.tt kPa). and 30 psI (1.4 kPa) fluid equivalent sidewall pressure.
2.3.6 Internal construction shall be designed to withstand the maximum expected conditions that include, but are not limited to, chemical, thermal, electrostatic and hydrostatic pressure.
3 SPECIAL REQUIREMENTS
3.1 Separation/Retention Efficiency
Rx disposal systenvs shall have a minimum separation/retention efficiency in accordance with ASME Al 12.14.3 or PDI-G1O1,
3.2 Application Documentation
Each FOG disposal system shall be provided with complete application instructions including, but not timited to, the following:
a) flow control and/or vent requirements (1’) any separate trapping requirements
fc) elevation and accessibility requirements (dl safety and health-related structkwis
fr) wiring instructions to reference national or local codes
(f) clean-out locations
(gi tnstructions that show the clearances required fur maintenance, cleaning, and prevention of hazards
3.3 Maintenance and Operation Documentation
Each FOG disposal system shall be provided with maintenance and operation documentation, which include a troubleshooting guide as well as instructions for performing necessary servicing or obtaining outside servicing. Units shall be provided with complete maintenance and operating instructions.
3.4.1 Installation shall be in accordance with the manufacturer’s recommendations and thc applicable plumbing codes.
3.4.2 Each unit shall be packaged with illustrated directions detailing correct installation procedures.
3.4.3 In buried applications of FOG disposal systems. access to each system shall be provided. There shall be access for each 10 ft (3-03 m) of length for FOG disposal systems over 21) It (6.1 m) long. Each access opening shall have a leak-resistant closure (i.e., lid) that cannot slide, rotate, or flip exposing the opening. and which does not require the use of mechanical fasteners and be of a vandal-resistant type.
3.4.4 Manholes, if applicable, shall extend to grade; have a minimum diameter size of 20 in. (510 mm) diame. tcr or 20 in. X 20 In, (510 mm X 510 mm); and shall be provided with a fitted, water-tight cover. Manholes shall be capable of withstanding all anticipated loads and comply with IAPMO PS-I, para. 4.7.1, which requires that all manholes have a leak-resistant closure that, when properly installed, cannot slide, rotate, or flip exposing the opening.. and which does not require the use of nwchanical fasteners.
