Operating Instructions
OPERATING INSTRUCTIONS eMASTER PRO HEATER
1. The heater will not operate without a fan blowing air
through the heater.
2. Plug in the number of heating elements for which you
have electricity.
3. Each heating elements pulls 7 amps of electricity. If you
have a 20 amp plug, you can plug two heating elements
into it. Once you have done this, turn on the red power
button.
4. Turn on the fan and make sure it is blowing through the
heater. The fan can be placed right behind the heater, or
it can be placed up to three feet away as long as it is
blowing air through the heater.
5. Press the black power button and all of the heating
elements you have plugged in should be operating. The
lights signaling power should also be displaying power by
lighting up.

THERMOSTAT OPERATING INSTRUCTIONS
1. If you wish to change the thermostat, take the following steps.
2. Hold the “S” set button until F1 shows on the screen.
3. Release the “S” set button.
4. Press the “S” set button and hold it. While holding it, use the
arrow keys to increase or decrease the temperature setting.
5. Then release the “S” button and press the “P” power button.
6. The recommended temperature setting is 77C. This is 170F.
As the fan pushes air through the heater, energy will be added
which we call heat. If you are using GreenTech Heat’s 4000
cfm fan, each minute 4,000 cubic feet of air will pass through
the heater and each time it passes through, the heater will add
heat/energy to the air until it reaches 170F/77C. Then the
heater will automatically shut off. It may take several hours to
reach the desired temperature, depending on the beginning
ambient temperature in the treatment area.
