20. The ignition control and pilot burner must both be chassis grounded.
21. Handle the pilot-electrode assembly carefully. If damaged, replace entire assembly. The correct spark
gap should be 7/64" to 1/8".
22. The pilots must be securely mounted relative to the main burner in such a position that main burner
ignition will occur with minimum delay with a low pilot flame just sufficient to open the main gas valve.
23. If the pilot fails to light when the control circuits are closed it may require manual resetting. Always wait
at least 5 minutes before resetting the system. To reset turn the main switch to pump #1/only, then back
to burner #2. Repeat if needed.
OPERATING INSTRUCTIONS
Following delivery and installation of your Delco pressure washer, inspect the unit for shipping damage and
follow these directions.
1. Observe all danger, warning, and caution statements.
2. Squeeze the trigger. Turn the control switch to position one (cold water wash). Allow the air to purge
from the system. Check the system for leaks.
3. Point the wand toward the floor. Flush out the system.
4. Turn the machine to the "OFF" position.
5. Install the nozzle onto the wand.
6. Turn the control switch to position one to establish the water flow. Turn the control switch to position two
(hot water wash). The burner should automatically come on. The burner should light in approxmately
one to thirty seconds. If delay is longer adjust the pilot and check spark gap (7/64").
NOTE: When the trigger gun is released for more than 4.5 minutes the machine will shut off. You
must turn the control switch to the "OFF" position then "ON" to restart. The timer is to protect the
pump and is not intended to take the place of the main "ON-OFF" switch.
WARNING: If the water should stop flowing from the gun, turn the unit off immediately and contact an
authorized Delco service person.
7. Point the wand toward the object to be cleaned and proceed.
8. For chemically enhanced cleaning, place the chemical feed line in liquid detergent. Open the metering
valve. Dial the metering valve to obtain the desired chemical concentration. Close the metering valve
for rinsing.
DANGER:
The detergent level should never fall below the chemical line strainer. If you should
discover this condition, immediately turn the metering valve off. Air introduced into the
system will cause pump damage and create steam space if the burner is on which may
lead to a steam explosion.
