|115 VAC heater jacket is not heating||Check the resistance between the black and white wires (tied together) and the blue wire. A 200 watt heater @ 115 VAC will draw about 2 amps so the resistance is around 61 ohms.||If the measure is open for heater resistance the fusible link has blown and the jacket should be replaced.|
|230 VAC heater jacket is not heating||Check the resistance between the black and white power wires using an ohmmeter. A 200 watt heater @ 230 VAC will draw about 1 amp so the resistance is around 245 ohms.||If the measure is open for heater resistance, the fusible link has blown and the jacket should be replaced.|
|Filter plug cannot be removed from filter housing||Check “O” rings for damage High particulate loading||Replace “O” rings |
Clean the “O” ring sealing surfaces with a clean towel prior to reassembly.
|Air from blowback tank keeps leaking onto sample when not activated||Voltage going to solenoid is 15VAC or less||Disassemble solenoid valve and clean flapper, if still leaking replace valve|
|Heater clamps not getting hot||Check for 110VAC going into the Clamps||Replace clamp|
