HOW TO PREPARE THE MACHINE FOR OPERATION
NOTE: Following delivery of your Delco pressure washer, inspect the unit for shipping damage.
Assembly:
1. Uncrate machine. Remove cleaner, parts package, gun and hose from shipping carton.
2. Assemble cleaner, gun, and hose. Do not install the pressure nozzle at this time.
3. Install the draft divertor.
4. Refer to the machine drawing in the service section for specific locations of parts you assemble.
Installation:
1. Do not install the machine in small confined areas, near exhaust fans or in a wash bay where the unit
could be subjected to overspray and cleaning chemicals. Install only in well ventilated areas where
adequate flow of air is available. Adequate oxygen is needed for combustion or dangerous carbon
monoxide will result. Stationary units should be installed in accordance with local plumbing and electri-
cal codes.
2. In all installations, this machine must be vented to the outside with a draft divertor and rain protection.
3. This machine is designed to be installed indoors and must be protected from direct spray or overspray of
water.
WARNING: Adequate oxygen is needed for proper combustion or dangerous carbon monoxide can
result.
Gas Fired Units:
Natural gas units operate on 31⁄2" of water column pressure at the solenoid valve, and it must have from 7"
to 8" water column pressure supplied to the unit at the inlet. The water column check points are as follows:
Check the 31⁄2" water column pressure from the plug on the bottom of the solenoid valve with the burner
operating. The water column pressure is checked with a manometer. A gas shut-off valve should be in-
stalled on the gas line, with a union between the shut-off and the unit. Also a sediment trap should be
installed after the shut-off valve.
Standard butane or propane gas fired units operate on 11" W.C. Use a gas Manometer when checking gas
pressure or when making adjustments to the regulator. Do not use less than 1/2" I.D. hose or pipe in mak-
ing the gas connection. For top efficiency, a 100 lb. or larger gas bottle should be used.
Minimum gas line iron pipe size required for gas supply per length of gas line from the meter (Natural Gas).
(Based on a pressure drop of 0.3" water column pressure and 0.6 specific gravity.)
NOTE: Do not use flexible gas lines. Check total BTU consumption of facility to be assured of proper
gas supply to operate pressure washer.
