and thermal shock. Carbon steel plate and cast iron shall be lined and
protected from direct contact with the washing solution by corrosion-resistant
metal (see 3.4.1).
3.5.2.3.2 Side loading machines. Side loading machines shall have one
sliding shell door for each longitudinal compartment, in the cylinder. The
doors shall be of the same material as the shell, shall be rigid, and shall
slide in continuous guides the full length of the door track. Doors shall fit
tight so as to prevent washing solution being splashed from the washer and shall
have latching means, lifting handles, and close fitting guides of corrosion-
resistant metal. The guides or tracks may be lined with polymerized tetra-
fluoroethylene (PTFE) to facilitate sliding of the doors. Interlocks on door,
or doors, shall not be bypassed and permit cylinder to operate because of
excessive amount of clearance at door guides, tracks, clips, or safety lugs.
These requirements shall be verified when the equipment is tested as specified
in 4.6.2. Renewable wearing strips may be fitted as roller tracks for safety
switches where they bear on the shell door.
3.5.2.3.3 Door openings. The shell door opening for end loading machines
shall be no more than 40 inches high for the 100-pound capacity machine; not
more than 42 inches high for the 200-pound capacity machine; and not more than
44 inches high for the 300-, 400-, 600-, and 800-pound capacity machines. The
shell door opening for side loading machines shall be not more than 41 inches
high with the shell door in a closed position. The measurement shall be from
the bottom of the door opening to the laundry floor surface without recessing
the machine into the floor.
3.5.2.4 Shell apron (side loading machines only). A hinged apron of the same
material as the shell shall be provided at each shell door of side loading
machines for bridging the space between the shell and cylinder.
3.5.2.5 Discharge outlet. A discharge outlet(s) with a quick-opening valve
or valves, shall be fitted at the bottom of the shell of all machines so as to
drain all water from the shell. The quick opening valves shall be of the open
design type. In the event of electrical or pneumatic failure, the quick opening
valves shall open automatically. These requirements shall be verified when the
equipment is tested as specified in 4.6.2. Working metallic parts of the valve
that come in contact with waste materials shall be of brass or corrosion-
resistant metal (see 3.4.1) and shall have a replaceable seat, diaphragm, or
gasket. In addition, the discharge outlet shall be non-splashing type or shall
be equipped with a splash guard which shall extend from the bottom of the shell
to within 2 inches of the bottom of the base mounting.
3.5.2.5.1 Drain valve sizes. The minimum drain valve sizes shall be as
follows: 2 inches for 25-pound capacity machine; 3 inches for the 50- and
100-pound capacity machines; 5 inches for the 200-pound capacity machine; 8
inches for the 400- and 600-pound capacity machines; and two 8 inch or one 10
inch for the 800-pound capacity machines. The pipe sizes and connections shall
be compatible with the drain valve sizes for the capacity specified.
