c) at least one of the modes shall comply with the requirements specified in Clauses 5.12.2.2.2,
5.12.3, and 5.12.4 for high efficiency. The manufacturer shall indicate which mode is to be tested
for high efficiency.
4.11.2.2
See Clause 6.4 for additional marking requirements for high-efficiency showerheads and hand-held
showers.
4.12 Cross-flow
4.12.1
Except as otherwise allowed by Clause 4.12.2, a flow-control device shall not completely shut off the
flow of water downstream of the primary shut-off valve when
a) fit
ted to a faucet or fitting; or
b) fit
ted to, or integral with, a showerhead or hand-held shower.
4.12.2
Faucets or fittings that have integral flow-control devices downstream of the primary shut-off valves
that completely shut off the flow of water or that have devices upstream of the primary shut-off valves
that might allow cross-flow shall have check valves installed in the faucet or fitting to prevent cross-
flow. These check valves shall comply with Clause 5.3.3.
4.13 Fittings incorporating electrical features
4.13.1 General
4.13.1.1
Electrical power to low-voltage circuits involving a peak open-circuit potential of not more than 42.2 V
shall be supplied by a
a) primary
battery supply;
b) suitable
Class 2 low-voltage transformer complying with the applicable CSA or UL
electrical
Standards;
or
c) combination
of a transformer and fixed impedance that, as a unit, complies with the
requirements
for
a Class 2 transformer specified in Item b).
4.13.1.2
Fittings incorporating electrical features other than low-voltage circuits shall comply with the applicable
CSA or UL electrical Standards.
Note: These standards include the following:
a) For
lighting products, CSA C22.2 No. 250.0 and CSA C22.2 No. 250.13 for Canada and UL 1598 or UL 8750
for
the
US.
b)
For
audio or video products, CSA C22.2 No. 60065 for Canada and UL 60065 for the US.
c) For
controls, CSA C22.2 No. 24 or the applicable CSA E60730 series standard for Canada and UL 873 or
the
applicable
UL 60730 series standard for the US.
d) For electric plumbing products and accessories, CSA C22.2 No. 14 or CSA C22.2 No. 68 for Canada and
UL 1951 for the US.
e) For
parts intended for installation in wet locations, CSA C22.2 No. 94.2 for Canada or UL 50 for the US, for
the
appropriate
degree of protection from ingress of moisture if applicable.
