ADJUSTING PUMP PRESSURE:
This machine is equipped with a pressure regulator (see
#6 on page 7), that allows the operator to adjust the pres-
sure between 100PSI and 1100PSI. The pressure required
for different textiles and surfaces will vary. Verify max
pressure for the specific surface you are cleaning to avoid
damage.
Do not adjust the pressure while spraying, as
the gauge will not display an accurate reading.
Do not
exceed 1100PSI. Verify max operating requirements and
limits of attachments to avoid damaging your ENDEAV-
OR or equipment. For example, a carpet wand should
not be run above 500PSI, if it does not have the correct
spray tips for that pressure. This could cause the pump
motor to overheat.
To adjust pressure:
1. Turn Pump switch to on position. Position “l”. Do
not spray.
2. Check current pressure on pressure gauge. (#5 on
page 7)
3. To increase pressure, turn the regulator in a
clockwise motion. Watch the gauge and stop
rotating the regulator when the desired pres-
sure has been reached. Max pressure is 1100PSI.

4. To decrease pressure, turn the regulator in a
counter-clockwise motion. Watch the gauge
and stop rotating the regulator when the de-
sired pressure has been reached. Minimum pres-
sure is 100PSI. Take care when reducing the
pressure below 100PSI as the regulator adjuster
nut may come off the threaded regulator shaft.

OPERATING THE HEATER FOR CARPET
AND UPHOLSTERY CLEANING:
The 9000I-HSH is equipped with a 2000watt heater. The
heater will only operate under the following conditions:
• When both power cords are plugged into two sepa-
rate circuits
• When the pressure on the machine has been reduced
to below 500PSI.
To use the heater:
1. Connect Solution line to #7 on page 7. Connect vac-
uum hose to #8 on page 7.
2. Connect your accessory wand or upholstery attach-
ment.
3. Place water in the solution tank using the Auto-Fill
feature or by using a bucket or hose to fill from
the solution tank access point (see #5 on page 6)
4. Turn Pump switch to on position. Position “l”.
5. Prime if necessary. See priming section on page 9.
6. Spray for 15-30 seconds or until you have a steady
stream. This will fill the heater tank with water and
prevent air pockets that could cause overheating.
7. Turn on heater switch to position “l”. If you are above
500PSI, the heater may not turn on until you reduce
the pressure to around 400-450PSI. Slowly reduce the
presure until the heater switch lights up green. If you
would like to increase the pressure to 500PSi, you may
do so. You may use the heater at pressures of 100-500PSI.
8. Once the heater switch light comes on, wait up
to 3 minutes for the heater switch light to turn off.
9. Once the light turns off, the heater is ready to pro-
vide hot water for carpet cleaning and upholstery
applications.
10. Use wet pass/dry pass spray patterns to allow the
heater sufficient time to heat the liquid passing
through the tank.
11. The light on the heater switch may stay on through-
out the rest of the job.
Note: The heater will not provide maximum heat for
accesories that require continuous spray. Because of the
current required to power the heater, the heater is dis-
abled while the pump is pressures above 500PSI. Do not
shut off the heater by increasing pressure as it may not
immediately turn off. Turn heater off using the switch.
