Teleflex Teleflex X45 Reference manual

X45 AIR COMPRESSOR
PRESSURE MEASURING &
SETTING PROCEDURE
Test Procedure
Proheat has an improved Air compressor pressure settings
procedure based on supply voltage to the heater.
1. Run heater until warm to the touch. This ensures the heater
components are up to normal operating temperature.
2. Switch heater off.
3.
Install the calibrated Pressure Gauge Tool PK0060 in-line as
shown in Figure A.
Calibrate gauge before each use see
www.proheat.com/PDFs/990614.pdf
NOTICE
Altitude Correction is needed above
3000 Feet (see inset on charts).
DO NOT adjust air pressure when
above 6000 Feet.
NOTICE
Remove Pressure Gauge when finished
with measuring & setting procedure.

4. Locate the rubber boot on the positive end of the ignition coil
and peel it back to expose the positive terminal.
5. Select the DC Volts range of a multimeter and connect as per
Figure B. The positive lead of the multimeter should be
attached to the positive coil lead. The negative lead of the
multimeter should be attached to the heater chassis at the
PROHEAT ground boss.
6. With the heater running in full output (flame on and ignition is
off) read the voltage and refer to the 12 or 24 volt chart
(Figure C and D) for the correct Air Pressure Reading.
7. The reading must be within the range of the shaded area as
shown in Figures C and D.

Compressor Adjustment After performing the above checks and the Air Pressure is still
outside the range for the measured voltage Adjust the air pressure
by turning the screw as shown in Figure E. Altitude Correction is
needed above 3000 Feet (see inset on charts).
DO NOT adjust air pressure when above 6000 Feet.
If the air compressor pressure cannot
be adjusted back into normal range,
replace air compressor.

Air Pressure Checks
If Air Pressure is outside the range for the measured voltage please
perform the following checks before adjusting the compressor:
Low Pressure Reading – Check:
i) Inspect air line from compressor outlet to fan end inlet for
leaks, kinks or other restrictions.
ii) Check condition of air compressor filter. Retest with the filter
removed.
High Pressure Reading – Check:
i) Nozzle and cavity for blockage. Refer to Step 5 on page 5-10
of the X45 service manual.
ii) Compressor is out of adjustment.
