Adjustments

 

The H5X/H10X dispensers hold the water tempera-

ture at the threshold of boiling. It is not adjustable by 
the user.
 

The H5E dispenser is factory calibrated for the 

temperature specifi ed on the data plate. If adjustment 
is required, use the following procedure:

1.  Fill the dispenser according to the steps in the Initial 

Set-up.

2.  Take the temperature of the stream of water im-

mediately below the faucet as it fl ows from the 
dispenser with an accurate thermometer.  Do not 
take the temperature of water collected in a con-
tainer.

3.  If any adjustment is required, refer to LEVEL 1
