ELECTRICAL INSTALLATION
ALL ELECTRICAL WORK MUST BE PERFORMED BY A QUALIFIED LICENSED ELECTRICIAN
AND CONFORM WITH ALL APPLICABLE ELECTRICAL SAFETY CODES
Toustravaux électriques doivent êtreeffectués par un électricienprofessionnel qualifié
et conforme àtous les codes applicables sécurité électrique
ALWAYS SWITCH OFF/DISCONNECT ALL EQUIPMENT IN THE WATER
BEFORE SERVICING OR PERFORMING ANY MAINTENANCE
Toujours éteindre l'équipement dans l'eau avant entretien ou de tout entretien
CAUTION: GFCI PROTECTION REQUIRED
If GFCI protection is not used, serious or FATAL electrical shock may occur
ATTENTION: GFCI/RCD de protection est nécessaire
Graves ou mortelles choc électrique peut se produire s'il n'est pas utilisé
WARNING: RISK OF ELECTRIC SHOCK
The AirFlo 3 must be connected to a grounded, metallic, permanent wiring system
Ground the compressor cabinet to the ground wire lead provided back to the service
using a copper conductor at least the size of the circuit conductors supplying the cabinet.
A. Branch Circuit Sizing (All valves must be in the open position before initial operation)
1. The branch circuit feeding the Otterbine AirFlo 3 must be sized in accordance with all applicable codes and must
provide GFCI (Ground Fault Circuit Interruption)/RCD (Residual Current Device) and short circuit protection. Refer to
the nameplate label on the compressor cabinet above the electrical connection box for voltage and current requirements.
The on/off switch provided with the AirFlo 3 does not provide personal (GFCI / RCD) electrical shock protection.
B. Electrical Connection
1. The AirFlo 3 is not considered to be portable
equipment and therefore flexible cord shall
not be used to connect the cabinet to the
power source. The electrical connection must
be considered permanent and suitable for a
NEMA 3R / IP34 environment.
2. A 1/2" (22mm) trade size conduit entry is
located at the bottom rear of the cabinet. If
using PVC conduit it is important to provide an
expansion coupling at the entry to the
compressor cabinet.
3. To make the conduit and wiring connections
remove the electrical compartment cover
shown on right. Pull the exposed field wiring
connection leads inside the electrical
compartment before making the conduit
connection.
4. When the field conduit and wiring is installed
connect the field wiring to the wiring leads
provided in the electrical compartment. Refer
to electrical schematic provided with the
Otterbine AirFlo 3 System. Replace the
electrical compartment cover when complete.

TUBING CONNECTIONS
A. Trenching
1. Determine the location where the air tubing will enter the water and dig a trench back to the compressor cabinet deep
enough to bury the Poly Unweighted Tubing.
B. Tubing Connections
1. Measure the distance between the compressor cabinet and the water’s edge, prepare a length of Poly Unweighted
Tubing for each diffuser manifold provided.
2. Use the couplings and clamps provided in PN: 12-0019 to couple each length of poly tubing to the heater hose
protruding from the rear of the compressor cabinet as shown.
3. Determine the distance between each Diffuser Manifold Base (PN: 10-0301 or PN: 10-0302) location and where the
Unweighted Poly Tubing ends. Prepare a length of the Weighted Tubing for each Diffuser Manifold.
4. Use couplings and clamps provided to connect the Weighted Tubing to the Poly Unweighted Tubing as shown below.
5. Using the hose clamps provided to fasten each Diffuser Manifold Base to the Weighted Tubing as shown.

DISC DIFFUSER BASE INSTALLATION
.
A. Ballast with Gravel
1. Fill the two (2) gravel compartments of
each Diffuser Manifold Base with 10-12
pounds of all-purpose gravel or until full.
Install the plugs provided (PN: 41-0276).
B. Place Diffuser Manifold Base
1. To place the Diffuser Manifold Base from the shore take an appropriate length of 1/8” nylon rope and from the bottom of
the base thread each end up through the two (2) holes opposite the weighted tubing as shown.
2. When power is available to the Compressor Cabinet, FULLY OPEN (TURN COUNTER-CLOCKWISE) ALL VALVES
ON ALL MANIFOLDS (See Page 6) and turn the switch inside to ON. Operating the compressor/s while placing the
Diffuser Manifold Base will help keep them right side up.
3. While holding both ends of the rope pull the pad into the desired position.
4. To remove the rope, pull one (1) end. If tying two (2) lengths of rope together be certain to pull the correct end with
respect to the knot.
5. Use the same method placing the Diffuser Base from a boat except two (2) ropes may be used on each end of the pad.
THREAD ROPE THROUGH DIFFUSER BASE PULL DIFFUSER BASE INTO POSITION
AIRFLO 3 SYSTEM OPERATION
A. CAUTION: The AirFlo 3 May Re-start Automatically
1. In the event of a compressor motor fault the internal motor thermal protection switch may trip shutting off the AirFlo 3
compressor. When cooled sufficiently the thermal switch will reset automatically which may cause the compressor to start
suddenly. If this re-occurs, turn the main switch down to OFF and contact an authorized service center.
B. Cabinet Ventilation
IMPORTANT: For proper Compressor Cabinet ventilation the cover must be kept closed and latched during operation.
1. There are two (2) cabinet ventilation fans. The right rear fan is thermostatically controlled and will start only when
internal cabinet temperature is above 30°C (86°F).
2. The fan on the left rear will operate continuously under normal conditions. If this fan is not operating when the main
switch is ON it must be replaced.

COMPRESSOR CABINET INTERIOR
B. Balancing Diffusers
1. ALL VALVES MUST BE IN OPEN (VERTICAL) POSITION BEFORE STARTING. (See below)
2. Turn the Main Switch up to ON.
3. The Air Pressure Gauge reading is at the minimum at this point.
4. Beginning with the Diffuser Manifold Bases in the shallowest depths, start turning clockwise (closing) the valves until
air begins to rise from the deeper bases. Continue slowly adjusting the valves from the shallowest bases to the deepest
until the diffused air pattern rising from each base appears to be equal. This will take some trial and error.
The valve supplying the Diffuser Manifold Base deepest in the water will remain fully open.
5. IMPORTANT: While balancing the diffused air patterns in the water attempt to maintain the lowest possible reading
on the air pressure gauge. Keeping the air pressure reading low as possible translates to the highest possible volume
(CFM) of air being distributed to the Diffuser Manifold Bases.
MANIFOLD VALVES SHOWN FULLY OPEN IN THE VERTICAL POSITION
IMPORTANT START-UP WARNING: RISK OF FISH KILL
When the oxygen level is less than 1PPM at the depth of the Diffuser Base, avoid the rapid release of noxious gas having
the potential to kill fish by adhering to the Otterbine recommended operation guideline below.
