HUMIDIFIER INSTALLATION
1. Mount Humidifier Unit in convenient location using
Mounting Bracket (not shown).
2. Connect air supply to HF-1/4” Air Inlet Valve.
3. Connect water supply to HF-1/4” Water Inlet Valve.
4. Open air inlet valve and water supply valve
under air
supply valve
check for leaks. Tighten connections if
required.
5.
Turn humidistat control dial on item #1 counter-
clockwise to off position before plugging cord into
grounded outlet
.
6. Reduce water flow by turning U-3670 needle stop
adjustment knob at back of spray gun.
Do not use to
shut off spray. If tightened too much needle can be
pushed through tip.
7. Set Regulator item #2, between 45 & 60. Start at 45 PSI
and increase until you get a nice atomization. Shop air
must be 80 PSI or higher.
8. Plug unit into properly grounded Outlet (115V., 60cy).
9. Turn Humidistat control dial to on position and desired
humidity. You will hear a “click” when activated.
10. Water flow rate may be adjusted using Item #13 for
Fluid Adjusting on back of each Spray Gun. Mist
should always be absorbed into the surrounding
air without settling out onto the floor under the unit.
CAUTION:
DO NOT AIM DIRECTLY AT CEILING,
WALL, MERCHANDISE OR MACHINERY.
SAFETY NOTE:
Do Not allow water vapor to
condense or leaks to drip onto floor or unit, if this
condition exists, check for:
a. Water leaks from connections or Spray Gun nozzles.
b. Insufficient atomization. Correct by increasing air
pressure and/or decreasing fluid flow.
c. Humidistat setting too high. Lower setting if necessary.
d.
Open drain valve on R-76 Regulator/Condenser
item #2
periodically to drain airline moisture buildup.
CAUTION:
Guard Face and Eyes so escaping air and
moisture do not cause injury.
WARNING:
Humidifier must never be used to create
a fog condition in which water may collect on the unit
and produce an electrical hazard.
