PREVENTATIVE MAINTENANCE
Check to see that water pump is properly lubricated.
• Follow winterizing instructions to prevent freeze
damage to pump and coils.
• Always neutralize and flush detergent from system
after use.
• If water is known to be high in mineral content, use
a water softener on your water system, or de-scale
as needed.
• Do not allow acidic, caustic or abrasive fluids to
be pumped through system.
•
Always use high grade quality cleaning products.
•
Never run pump dry for extended periods of time.
• Use clean diesel fuel. Clean or replace fuel filter
every 100 hours of operation. Avoid water con-
taminated fuel as it will damage the fuel pump.
• If machine is operated with smoky or eye burning
exhaust, coils soot up and prevent water from
reaching maximum operating temperature. (See
section on Burner Adjustments.)
• Never allow water to be sprayed on or near the
engine or burner assembly or any electrical com-
ponent.
• Periodically delime coils per instructions.
• Check to see that engine is properly lubricated.
It is advisable, periodically, to visually inspect the
burner. Check air inlet to make sure it is not clogged
or blocked. Wipe off any oil spills and keep this equip-
ment clean and dry.
The flow of combustion and ventilating air to the burner
must not be blocked or obstructed in any manner.
The area around the pressure washer should be kept
clean and free of combustible materials, gasoline and
other flammable vapors and liquids.
Unloader Valves
Unloader valves are preset and tested at the factory
before shipping. Tampering with the factory setting
may cause personal injury and/or property damage,
and will void the manufacturer's warranty.
Winterizing Procedure
Damage due to freezing is not covered by warranty.
Adhere to the following cold weather procedures when-
ever the washer must be stored or operated outdoors
under freezing conditions.
Trailer Winterization
To protect your machine from severe damage
caused by water freezing inside the components, it
is important to winterize it whenever it is subjected
to freezing temperatures.
The best way to protect the system is to keep it out
of the cold. Barring that, the next best way is to
flush the system with antifreeze. To do so, follow
these steps to properly operate the anti-freeze pro-
tection system. This system is designed to protect
your equipment during cold weather conditions
of 32°F or below. Your ECOS trailer comes with a
factory installed winterization system.
Be sure to wear safety glasses and gloves when
winterizing system.
Inner And Outer Water Tanks
•
After operation, turn engine off, drain all yellow
tanks by removing debris filter cap located behind
control panel and turn both tank valves to the open
position. If there is still water in the tank, lower the
front end of the trailer with the jack to completely
drain the tanks. Use a wet-dry vacuum to suck
the remaining water from the drain ports at the
bottom of the tanks.
•
Once tanks are drained, replace debris filter cap
and turn both tank valves to the off position.
Coil, Heat Exchanger, Inlet Feed Pump, and
High Pressure Hose
•
Relieve any pressure in wand and hose. Close
both tank valves located in the control cabinet.
Keep gun and wand attached to high pressure
hose and remove high pressure nozzle.
•
Pour a minimum of a 5 gallons of environmentally
safe antifreeze mixture into two 5 gallon buckets.
(Determine what is the best mix ratio for your
environment).
•
Remove the plug on the antifreeze inlet line lo-
cated in the control panel cabinet. Place open
line into antifreeze mixture. Have a second 5
gallon bucket ready to collect antifreeze recycling
through system.
•
While holding open the gun trigger, start the
engine to draw the antifreeze solution into the
system. Keep the gun open. Once antifreeze can
be seen coming out of the wand, release the gun
trigger and allow the system to run in bypass for
15 seconds. While in bypass, switch the bypass
valve on the control panel to the other tank and
continue to run in bypass for another 15 seconds.
Turn the key to the OFF position.
•
Remove the inlet feed line from the antifreeze
mixture and replace the plug.
