DO NOT connect directly to AC power. Doing so
will cause permanent damage to Nafion dryer.
WARNING!
Filter Heater Thermocouple Connection (Optional)
If sample condensate is expected, an automatic drain assembly is used, a second
therm couple is mounted on the filter section. This thermocouple must be wired to
an additional temperature controller provided by customer.
1. Locate thermocouple mounted through outer insulation on filter section
(labeled “Filter Heater Thermocouple”).
2. Connect Type J thermocouple extension wire from connector provided to an
additional temperature controller. This controller will be used to control
filter heater’s power instead of internal pre-set thermostat.
Automatic Filter Drain Valve Connection (Optional)
Optional solenoid valve can be connected to filter section if automatic draining of
sample condensate is desired.
1. Locate Automatic Filter Drain Valve two pole connection.
2. Connect to customer’s control system.
B. Dryer Section
Dryer Heater Connection
1. Locate 3 pole connector (labeled “Dryer Heater”).
2. Connect wires to customer supplied PID type temperature
controller.
Dryer Heater Thermocouple Connection
1. Locate thermocouple mounted in tee fitting of purge outlet port
(labeled “Dryer Thermocouple Type J”).
2. Connect Type J thermocouple extension wire provided to customer
supplied temperature controller to control dryer heater power.
C. Ground Wire Connection
1. Locate green wire separate from any other wiring harnesses.
2. This is the grounding wire for the GASS Module.
3. Connect grounding wire to appropriate earth ground.
