Ambient Pressure
0.8 to 1.2 Bar (11.8 psia to 17.6 psia)
Ventilation

Cleaning
With unit OFF and unplugged, exterior surfaces
may be wiped clean using a damp cloth.
Attaching 230V (European style) plugs
(see diagram):
NOTE: Use plug appropriate for local area and codes.
Only qualified personnel should perform wiring.
Overcurrent protection should be provided external
to the heater unit within plug type shown or similar fusing.
Protective Earthing
The yellow and green ground wire in the power cable is attached directly to the aluminum
base plate inside the heater via a dedicated screw terminal. Additional protective earthing
can be attached to the aluminum base plate if desired.
Basic Operation
1. Turn SKORPION air heater ON using two switches:
1.1. Switch S1 (blower) sends power to the blower and to heater switch S2.
1.2. Switch S2 (heater) sends power to the heater control circuit.
1.3. Note, for heater safety, S2 (heater) cannot turn ON without S1 (blower) ON.
2. Adjust airflow via a rotational air damper at the blower inlet.
3. Adjust temperature set point with the UP/DOWN arrows on the temperature controller.
Heater will ramp to temperature.
3.1. The process temperature is measured with an internal type “K” thermocouple located at
the end of an element inside the stainless housing.
4. When turning the heater off the heater power (S2) may be turned off and the blower (S1)
left on to cool the heater housing assembly. This is suggested to prevent burn injury of
personnel around the heater but is not necessary for safety of the heater element.

Detailed Operation
•
•
Heater Voltage is regulated by a Solid State Relay (SSR), which is turned ON and OFF
rapidly according to the temperature controller DC OUT signal. A “zero cross” type SSR
is used to minimize electrical noise.
Heater Element is protected with a resistive photo detector and a thermal resistor
(thermistor) mounted at the heater inlet. These sensors are connected in parallel with the
DC input signal going to the SSR.
o
o
o
If the element overheats (bright orange color) the photo detector resistance
decreases which reduces the control signal which, in turn, limits power to the
heater.
If the air temperature in the housing reaches an unsafe level, the thermistor
resistance decreases which reduces the control signal, which in turn, limits power
to the heater.
A small fixed resistor in series with the control signal sets element and air
temperature limits.
•
The large black dots on the wiring diagram represent connections that are made on the
internal terminal strip. The terminal strip allows the customer easy access to remove and
replace the heater element and blower if necessary.

* FOR SKORPION models without Blower (external air source):
A) The maximum temperature capability of heater will depend entirely on the airflow rate
produced by external air source. Higher airflow rates than those produced by the standard
SKORPION blower will yield lower maximum temperatures.
B) External air supply must be turned ON prior to turning heater ON
C) For best flow conditions, use min. ꢀ” NPT size incoming air line.
D) Do not exceed 5 psi (.34 BAR) or air leaks will be noticeable in the heater.

Replacement Procedures
I. Replacing the Heating Element
1. Turn heater/blower switches OFF, and disconnect from power source.
2. Use a flat screwdriver to remove (pry open) the wiring cover under the stainless nozzle
tube.
3. Remove the stainless nozzle by removing the two mounting screws, and the thru-bolt
which passes through the plastic support tower and threads into the nozzle flange.
4. Disconnect the KTC+ (Yellow), KTC- (Red), HTR1, HTR2 connections from the wiring
terminal as shown. Total of four wires.
5. Remove the old element, pulling the KTC and HTR wires through the plastic support
tower.
6. Install new element by reversing steps 2-5.
II. Replacing the Temperature Controller
1. Turn heater/blower switches OFF, and disconnect from power source.
2. Remove the four screws which secure the black plastic top cover plate.
3. Remove the four screws which attach the aluminum base plate to the main heater plastic
structure.
4. With the top cover plate and the aluminum plate removed, you now have access to the
top and bottom mounting tabs on the temperature controller.
5. While lifting the top and bottom white plastic mounting tabs, gently push the temperature
controller halfway out of the faceplate.
6. Using masking tape or other method, mark each wire going to the back of the controller
with a number 1-9, corresponding to its terminal location. This is CRITICAL to ensure
proper wiring to the new controller.
7. Using a small screwdriver, loosen and remove the wires from the terminals at the rear of
the temperature controller.
8. Remove temperature controller completely from the faceplate.
9. Install new temperature controller halfway into faceplate.
10. Reconnect the wires according to the terminal number and ID marking from step #4.
11. Press controller into faceplate while engaging the white mounting tab securely.
12. Replace the black plastic top cover plate and reattach mounting screws.
