1.4 Electrohydraulic Water Closet
An electrohydraulic water closet is a siphonic or wash-down water closet as described in ASME Al l2.19.2M with a nonmeehanical trap seal. The water closet incorporates electrical motor(s). pump(s). and controllers to facilitate the flushing action.
In this Standard, the term water closet means an electrohydraulic water closet unless otherwise indicated.
2.1 General
2.1.1 Water Closet. The water closet shall conform to the requirements contained in ASME Al l2.19.2M or ANSI Z124.4. as appropriate. It shall also meet the requirements of ASME Al 12. 19.6.
2.1.2 Electronic and Electrical Components. The electronic and electrical components utilized in the water closet shall comply with the appropriate Underwriters Laboratories (UL) standard or portions thereof as may be indicated in this Standard.
2.2 Pump System
The pump systems of an electrohydraulic water closet shall be tested as a waler pump in accordance with UL 778. The applicable sections of UL 778 for compliance are:
(a) Construction. sections 1 through 8 and 10 through 28;
(b) Performance. sections 29 through 35 and 37 through 47;
(C) Manufacturing and Production Tests. sections 49 and 50:
(d) Rating. section 51;
(e) Markings. sections 48. 52. and 53:
(f) Instruction. sections 54 and 55.
2.3 Pump Motor and Impeller
The pump motor to the pump impeller couphng shall he nonmechanical and seamless. To minimize electrical haiards. the design shall provide a completely sealed chamber for the motor and electronics without the useof seals or O-rings.
2.4 Pump Housing
Electric motors or pump enclosures shall complywith UL 746C and be plastic rated 94-5v or better asspecified in UL 746C.
2.5 Jet Hose
The pump jet hose,if provided,shall withstand apressure of 25 ± 1 psi (172 ± 6.9 kPa) for 60 min.
2.6 Printed Wiring Boards
Wiring boards shall comply with UL 244A-1994,sections 14.1 and 14.2,and UL 796.
2.7 Switches
Switches shall be located in class 2 circuits only.
NOTE: A class 2 circuir is a circuit with an open potential of nomore than 30 v rms (42.2 V peak) supplied by either an inherentlylimited class 2 transformer or by a transformer and fixed impedancethat together comply with all the requirements for inherently limitedclass 2 transformers in UL 1585.
2.8 Electrical Supply Cord
Electrical supply cords shall be provided with 3 ft(0.9 m) minimum, 6 ft (1.8 m) maximum of permanently
attached cord and an attachment plug for connection
to the branch-circuit supply. The cord shall conformto UL 62 or UL817. Tshall be marked “WaterResistant” and include an equipment-grounding conduc-
tor. Where the electrical supply cord exits the fixture,the surface shall be smooth,with rounded surfaces orprovided with a grommet.Seals and gaskets shallconform to UL 157.
