FAN SYSTEM
FAN WON’T RUN AND MAKES NO SOUND
Check power cord, extension cord, switches, circuit
breaker
•Reconnect power or extension cord; Reset breaker
FAN WON’T RUN MAKES HUMMING SOUND
Blade in contact with shroud
Re-center blade hub
Motor stalled (will not turn by hand)
Replace motor
BREAKER TRIPS OR FUSE BLOWS WHEN FAN IS
STARTED
Motor stall
Replace motor
Check power source for min. 120 volt/10 amp
Upgrade power supply
Extension cord gauge too small
Replace with heavier cord
MOTOR OVERHEATS, SHUTS OFF AND RESTARTS
SEVERAL MINUTES LATER
Extension cord gauge too small
Replace with heavier cord
Inlet air obstructed or too close to wall
Provide minimum 3 feet inlet clearance
Faulty motor
Replace motor
FAN MOTOR WON’T RUN SWITCH MAKES SOFT
CLICKING SOUND
Ensure that switch is making good contact
Replace switch if needed
FAN BLADE DOESN’T TURN UNIT MAKES
SQUEALING SOUND
Motor stall (will not turn by hand)
Replace motor
FAN WILL NOT REACH SPEED BUT TURNS AND
MAKES HUMMING SOUND
Check Capacitor (where visible) and motor electrical
connections
Replace capacitor or motor
Extension cord gauge too small
Replace with heavier cord
WATER SYSTEM
The water distribution system consists of two (2)
assemblies:
1. The Water Inlet Assembly
•Brass bulkhead tting
•Float valve assembly
2. The Hose and Valve Assembly
•Spray Bar Assembly
•Valve Assembly
•Connection Hose
FLOOR AT SIDE OF UNIT IS WET
Water inlet hose is loose at supply hose or inlet hose is
loose at bulkhead tting.
Tighten connections and/or replace hose washers.
UNIT OVERFLOWS FROM RESERVOIR OR IS
SPITTING WATER THROUGH FAN
Float valve hose is loose at bulkhead tting or at oat
valve.
Tighten connections and/or replace hose washers
Water pressure is too high to allow oat valve to
shuto (120psi max)
Reduce water pressure by adding an inline reducer
Float valve not properly seated
Check all hoses for leaks
WATER SPITTING FROM THE UNIT
Check The Hose and Valve Assembly
•Reduce ow control setting
•Replace cracked hose and valve assembly
•Tighten hose connections
•Adjust spray bar
•Ensure pads were installed correctly
WATER LEAKING FROM DRAIN VALVE
Check for worn washer, stem or open drain valve
•Replace washer
•Replace drain valve
TOO MANY DRY STREAKS ON THE PADS
Check for blocked holes in the spray bar or adjust
water ow
•Remove spray bar, remove plug and clean tube and
holes
•Open water ow control valve
PUMP
PUMP MOTOR WILL NOT RUN WHEN SWITCH IS
TURNED ON
Turn fan on to check for power
•If fan doesn’t start check breaker and cord plug-in
•If fan does start; check for power to and through
pump switch (when turned on)
Ensure water level is high enough to make the low-
water cut-o circuit
Fill water reservoir
PUMP MOTOR HUMS WHEN SWITCH IS TURNED
ON, BUT DOES NOT PUMP WATER
Obstruction in impellor
Remove object(s)
Pump motor failure
Replace pump
BREAKER TRIPS OR FUSE BLOWS WHEN SWITCH IS
TURNED ON
Check power cord length and breaker rating
Refer to page (2) for unit amperage draw and to
determine required cord gauge
Check for locked-up pump
Replace pump
PUMP RUNS BUT DOES NOT PUMP WATER
Air lock in outlet side of pump
Turn o and on to bleed
Ensure the impellor is turning in pump
If not, replace pump
INTUITIVE CONTROL PANEL ERROR CODES
E1 OVER CURRENT PROTECTION
Current draw too high
•Check extension cord size
•Check motor spins freely
•Check airow not obstructed
•Replace motor
E2 OVER VOLTAGE PROTECTION
Supply voltage too high ≥ 132V
•Try dierent circuit
•Install Voltage Regulator
E3 LOW VOLTAGE PROTECTION
Supply voltage too low ≤ 108V
•Try dierent circuit
•Install voltage regulator
E4 LOSS OF PHASE PROTECTION
Motor phase imbalance
Loose or disconnected motor wire, Replace motor
E7 OVERLOAD PROTECTION
Motor running too hot
Check extension cord size, Check motor spins freely,
Check airow not obstructed, Replace motor
F6 COMMUNICATION FAILURE
Failure of communication between control panel and
control board
Check connection of control cable, Check control cable
not broken
