A. Operational Test of the Beverage Maker

WARNING: DO NOT TOUCH THE UNIT UNTIL IT IS SUFFICIENTLY COOL TO PREVENT BURNS WHEN YOU DO THE MAINTENANCE TASK(S).

WARNING: BE CAREFUL WHEN YOU OPERATE GALLEY EQUIPMENT WITH HOT WATER OR STEAM. HOT WATER AND STEAM ARE DANGEROUS AND CAN BURN YOU.

WARNING: OPEN THE WATER FAUCET OR THE WATER DRAIN CAREFULLY AND SLOWLY. THE TANK IS PRESSURIZED AND STEAM OR VERY HOT WATER CAN COME OUT OF THE NOZZLE. HOT WATER OR STEAM IS DANGEROUS (IT CAN BURN YOU).

(1) Use the CONTAINER 3 L(3/4 USGAL) to collect water from the water faucet during the test.

ACTION	RESULT
1.At the galley:
Close the potable-water shutoff valve.
2.At the beverage maker: Hold an empty server below the water faucet and open the water faucet.	At the beverage maker: Water flows from the water faucet into the server.
Hold the water faucet in the open position.	After a short time, the water flow stops.
Close the water faucet.
Push the POWER pushbutton switch.	The POWER and the LOW WATER indicators come on.
3.At the galley: Open the potable-water shutoff valve.
4.At the beverage maker:	At the beverage maker:
Hold an empty server below the water faucet. Open the water faucet to bleed the air from the tank until the water comes from the water faucet.	Water flows into the water tank.
Close the water faucet when the water starts to flow.	The water flow stops. After a short time, the LOW WATER indicator goes off.
Put an empty server in position and lock the brew handle in the down position.
Push the BREW and the WARMER pushbutton switches.	The BREW and the WARMER indicators come on. If the water has the set temperature, the hot water flows through the brew cup into the server.
Release the brew handle to the up position.	The BREW indicator goes off and the hot water flow through the brew cup stops.
Hold an empty server below the water faucet and open the water faucet.	Water flows from the water faucet into the server.
Close the water faucet.	The water flow stops.
5.At the beverage maker: Put an empty server in position and lock the brew handle in the down position.	At the beverage maker:
Push the BREW pushbutton switch.	The BREW indicator comes on.
	After a short time, the hot water flows through the brew cup into the server. After a short time, the water has the set level in the server and operates the level sensor. The water flow stops and the BREW indicator goes off.
Hold an empty server below the water faucet and open the water faucet.	Water flows from the water faucet into the server.
Close the water faucet.	The water flow stops.
6.At the beverage maker: Push the POWER and the WARMER pushbutton switches.	At the beverage maker: The POWER and the WARMER indicators go off.
