for lavatories. The assembly shall be a standard manufactured unit and may
have a rubber-gasketed swivel joint.

GREASE INTERCEPTORS
**************************************************************************
NOTE: Concrete pit must be detailed on structural
drawings.
**************************************************************************
[Grease interceptors of the sizes indicated shall be constructed of
reinforced concrete, [or of precast concrete construction] [or equivalent
capacity commercially available steel grease interceptor] with removable
three-section, 9.5 mm 3/8 inch checker-plate cover, and shall be installed
outside the building.] [Steel grease interceptor shall be installed in a
concrete pit and shall be epoxy-coated to resist corrosion as recommended
by the manufacturer.] Interceptors shall be tested and rated in accordance
with PDI G 101. Concrete shall have 21 MPa 3000 psi minimum compressive
strength at 28 days.
2.11
GARBAGE CAN WASHER
Garbage can washer shall be capable of cleaning cans up to 635 mm 25 inches
in outside diameter. Garbage can washer basin shall be fabricated of
corrosion resisting steel, and the basin supports shall be of [galvanized]
[malleable iron] [carbon steel].
2.12
DISHWASHING MACHINES
[Commercial dishwashing machines shall conform to NSF 3, NSF 5, and UL 921.]
[Household dishwashing machines shall conform to UL 749 and ASSE 1006,
sized as indicated.]

WATER HEATERS
**************************************************************************
NOTE: Coordinate with the HVAC engineer the
availability of heating source and control air in
order to make proper selection of bracketed choices.
The option for phenolic resin coating for heaters
with service water in the shell and steam or hot
water in the coil should be used only at locations
where scaling on coil surfaces due to water hardness
is severe or where corrosion-induced leaks are a
severe problem.
Location of water heaters should be shown on the
drawings.
Also, the type, capacity, etc. of each unit should
be scheduled on the drawings.
Except for gas-fired water heaters, water
temperatures in excess of 60 degrees C (140 degrees
F) should be obtained by using a booster heater in
series with a primary heater. Hot water systems
utilizing recirculation systems should be tied into
building off-hour controls. When using a gas-fired
