probe, tank or tank heater

for excessive lime deposits. Delime

 

 

 

 

as required.

 

 

2. Temperature Probe

Remove the probe from the grom-

 

 

 

 

met and submerge in a water bath

 

 

 

 

of approximately 70°F(21°C). Con-

 

 

 

 

nect an ohmmeter to pins 3 and 4 of

 

 

 

 

the J3 connector. At 60°F(16°C) the

 

 

 

 

reading should be 15.3k ±2k OHMS,

 

 

 

 

at 70°F(21°C) the reading should

 

 

 

 

be 11.8k ± 2k OHMS, and at

 

 

 

 

80°F(27°C) the reading should be

 

 

 

 

9.3k ± 2k OHMS. If the probe is

 

 

 

 

within these parameters, reconnect

 

 

 

 

the J3 plug to the control board.

 

 

3. Control Board

Set the temperature to 200°F(93°C).

 

 

 

 

Let tank temperature stabilize. If

 

 

 

 

temperature in tank is above tem-

 

 

 

 

perature setting by more than 7°F,

 

 

 

 

replace the control board. (See page
