See also 1.1.1.2Method of TestThis test is combined with that of 2.3.2.3 Leakage and DrippageThere shall be no

14、 leakage from the unit during a dispensing cycle nor a continuous drippage fromthe dispensing nozzle following a dispensing cycle or during any standby period. This latterrequirement is waived during the heating of the tank from a cold start.Method of TestThe test unit shall be set up according to t

15、he manufacturers instructions and be connected to anadequate water and electric supply. A thermocouple shall be installed just inside the dispensingnozzle within the water stream. The electric supply must be capable of maintaining the voltage andamperage, or wattage, shown on the name plate. Previou

16、s to energizing the heater, open thesupply valve and hold the dispensing valve open until water runs freely from the dispensing nozzle.Energize the heater. When the thermostat opens at the tank service water temperature, open thedispensing valve and check the maximum temperature of the discharging w

17、ater. Allow the waterto flow until the thermostat closes and immediately close the dispensing valve. Allow the tank toheat until the thermostat again opens. Observe for any drippage from the nozzle. Repeat the abovetest. Following this, run 10 dispensing cycles drawing 6 oz. of water for each cycle

18、allowing a periodof two minutes between the draws. Observe for any drippage from the nozzle.2.4 Product RejectionFailure to comply with any requirement of this standard shall be cause for the rejection of the modelof the device tested.4 Hot Water Dispensers Household Storage Type ElectricalASSE #1023 1979American Society of Sanitary EngineeringFOR PLUMBING AND SANITARY RESEARCH901 Canterbury Road, Suite A Westlake, Ohio 44145-1480 USATEL: (440) 835-3040 FAX: (440) 835-3488E-mail: general.infoasse-plumbing.org Web: http:/www.asse-plumbing.org
