OPERATION
REVIEW AND UNDERSTAND ALL WARNINGS IN THIS MANUAL. THEY ARE
ESSENTIAL FOR SAFE USE OF THE HEATER. FOLLOW ALL LOCAL CODES.
To start heating:
1. Place the heater on a stable, level surface. Make sure that no explosive or combustible fumes
or dust are present. See that the heater is not exposed to water spray, rain, or dripping water.
Minimum clearances from combustible materials:
Outlet: 6 feet, Sides: 1 foot, Top: 2 feet, Rear: 2 feet
Floor: combustible
2. Connect heater to proper power source. The P600 requires a 240V, 60Hz single phase 25 Amp
power source. The P900 requires a 240V, 60Hz single phase, 40 Amp power source. The
P1800-1 requires a 240V, 60 Hz single phase, 75 Amp power source. The P1800-3 requires a
240V, 60 Hz three phase, 50 Amp power source. The P4000 requires a 480V, 60 Hz three
phase, 50 Amp power source. The P6000 requires a 480V three phase, 75 Amp power source.
Also,
ALL POWER SOURCES NEED TO BE EQUIPPED WITH A CIRCUIT BREAKER!
Note: When power is first applied to unit, the heater fan may blow
air out of heater INLET. If this condition occurs, (after first
removing power from cord) reverse the first two hot wires at heater
terminal inlet block. (3 Phase Models Only)
3. Set the remote thermostat to a temperature above the ambient room temperature by turning
the knob. NOTE: The heater will start only if the thermostat “calls for heat” meaning that it is
set to higher than prevailing ambient temperature.
4. Set the selector switch to the desired heating setting. For the P1800 series, the options are #1
for ventilation (fan only), #2 for low heat output of 12Kw (41,000 Btu’s), or #3 for high
output of 18Kw (65,000 Btu’s).
For the P4000, the switches are labeled S1 with a heat output of 16Kw (54,600 Btu’s), S1 and
S2 with a heat output of 32Kw (109,200 Btu’s) or S1, S2 and S3 with a heat output of 40Kw
(136,000 Btu’s).
For the P6000, the switches are labeled S1 with a heat output of 24Kw (81,900 Btu’s), S1 and
S2 with a heat output of 48Kw (163,800 Btu’s) or S1, S2 and S3 with a heat output of 60Kw
(204,700 Btu’s).
The heater will now operate automatically, controlled by the thermostat.
