OPERATING INSTRUCTIONS FOR AIR
PRESSURE WAX INJECTOR
1. Remove top cover plate by loosening two black knobs located on top of
aluminum cover.
2. Put in approximately 1 -2 pounds of wax and replace cover, tightening
the knobs evenly.
3. Connect the air line from your compressor to the input nozzle, located to
the right of the regulator assembly. A hose clamp should be used to
prevent any leaks.
4. Plug the unit into a standard, grounded 110v outlet. (if you have a 220v
unit, you would need a 220v outlet.) turn unit on using the O /OFF toggle
switch located on the units body.
5. Put a stainless steel thermometer into the wax chamber through the hole
in the cover. Adjust thermostat on the side of the unit to normal operating
temperature approximately 1600F/710C. The Temperature on the
thermometer should approximately be equal to that of the dial setting. If
the set temperature differs with that of the thermometer by 150or more the
thermostat should be readjusted.
The air pressure required will vary from 4-5 psi for simple and heavy designs
to 9-12 psi for thin and complicated designs. Air pressure is adjusted by
turning the regulator knob counter clockwise to decrease pressure and
clockwise to increase pressure, after the desired pressure is obtained the
regulator can be locked by pushing the regulator knob inward towards
regulator body. By locking the regulator at desired pressure it offers hours of
operation with out having to constantly readjust regulator.
The air pressure wax injector has a safety air escape valve (located to the
left of the regulator assembly) which automatically releases excessive
pressure from pot. There is also a spigot on the side of the pot which enables
you to drain the pot of molten wax whenever.

PRECAUTIONS
Rejected patterns may be reused. Melt and pour through layers of fine cloth
to remove all impurities. For best results however, use at lest 50% fresh wax

As with all electrical equipment, certain precautions should be taken when
operating your wax injector:
- Keep work area clean and well light.
- Avoid dangerous work environments - do not use in damp or wet
locations, or near chemicals and or corrosives. EVER SUBSTITUTE OXYGE
I STEAD OF COMPRESSED AIR FOR THE OPERATIO OF THE WAX I JECTOR.
THERMOSTAT ADJUSTME T PROCEDURE
Remove the white temperature dial by pulling it straight off of the unit. Turn
the slotted head screw located within the thermostats shaft way until the light
goes on and off at the desired temperature. Replace the dial. The
thermostat is now recalibrated.
The Manufacturer reserves the right to void any and all
warranties which may apply to the purchase of a new unit,
