 A. Adjustment of the Water-Faucet Flow Time
 NOTE : Make sure that the water nozzle is clean and not calcified before
____
 you do this task|

 NOTE : The manufacturer has pre-adjusted the flow time of the
____
 water-faucet to 10 +2-2 s.

(1)
 Set the water-faucet temperature control to the central position before you adjust the water-faucet flow time.

 (2)
 Remove the placard (1) from the lever cap assembly (4).

 (3)
 Put a SCREWDRIVER - SMALL through the hole into the self-closing element (3) until it engages in the slot of the regulating needle (2).

 (4)
 Use the screwdriver to turn the regulating needle (2) clockwise until it stops.

 NOTE : Do not use to much force when you do the above step.
____
 (5)
 Push the water faucet:

 -no water will flow.

 (6)
 Turn the regulating needle (2) slowly counterclockwise to increase the flow time.

 (7)
 Push the water-faucet and measure the flow time.

 NOTE : The water pressure and temperature effect the flow time of the
____ water faucet; the colder the water, the longer the flow time.

 (8)
 Adjust the regulating needle again until the necessary flow time is reached.

 (9)
 Put the lever cap assembly (4) in the middle position and install the placard (1). Make sure that the red mark (warm) is on the left and the blue mark (cold) is on the right.

 (10) Make sure that the cap assembly (4) is in the middle position between the COLD and HOT range.

(1)
 Set the water-faucet temperature control to the central position before you adjust the water-faucet flow time.

 (2)
 Remove the knob (3)

 (a)
 Remove the cove (1).

 (b)
 Use a WRENCH - HEXAGONAL and loosen the screw (2).

 (3)
 Use a SCREWDRIVER - FLAT HEAD and adjust the water-flow time as follows:

 (4)
 Turn the adjusting screw in the water faucet (4) clockwise to decrease the flow time.

 (5)
 Turn the adjusting screw counterclockwise to increase the flow time.

 (6)
 Operate the water faucet (4).

 (7)
 Use a STOPWATCH and make sure that the water flows for between 10 and 18 seconds.

 NOTE : The water pressure and the temperature effect the flow time of
____ the water faucet; the colder the water, the longer the flow
 time. R The maximum flow time of the water should not be more than 16 R seconds.
 (8)
 Do the procedure again if the flow time is not satisfactorily.

 (9)
 Put the knob (3) in position and tighten the screw (2).

 (10) Install the cover (1).
