Installation

Unpack and inspect contents. Ensure mounting surface is stable and can support unit weight.

  1. Select Location: Choose a well-ventilated area with clear intake/exhaust paths.
  2. Mount Unit: Use provided brackets and hardware. Secure to wall, ceiling, or duct flange.
  3. Electrical Connection: Connect to dedicated circuit with proper grounding. Follow local codes.
  4. Duct Connection: Attach ducting to intake/exhaust flanges using appropriate clamps.
  5. Final Check: Ensure all fasteners are tight and no obstructions are near the impeller.

WARNING! Unit is heavy; use proper lifting equipment or two-person lift. Disconnect power before installation.

First-Time Setup

After installation, perform initial setup before first use.

  1. Power Check: Ensure voltage matches nameplate (230V).
  2. Direction Check: Verify desired airflow direction (intake/exhaust).
  3. Test Run: Turn speed control to minimum. Power on. Gradually increase speed.
  4. Inspect: Listen for unusual noises or vibrations. Ensure smooth operation.
  5. System Integration: Connect to control system if applicable (e.g., thermostat, timer).

CAUTION! Do not operate without proper ducting or with blocked airways. Ensure electrical connections are secure.

Specifications

Controls and Settings

Unit features a front-mounted control panel and optional remote control capability.

Local Controls: POWER switch, SPEED control dial, DIRECTION switch (optional models), RESET button (overload).

Remote Control (Optional): Can be connected to external 0-10V signal or dry contact for start/stop.

Settings: Speed is adjusted via rotary dial. Airflow direction is set via internal DIP switch (requires cover removal). Overload protection resets automatically after cooldown; manual reset via button if triggered.

Connecting to Systems

Can be integrated into ventilation, exhaust, or material handling systems.

  1. Ducting: Use rigid or flexible duct of appropriate diameter. Secure with clamps.
  2. Electrical: Hardwire to approved disconnect switch or plug into dedicated outlet.
  3. Control Systems: For automated operation, connect control wires to terminal block (see wiring diagram).
  4. Filters: Install intake filter if required for application (not included).

Tip: Ensure duct runs are as straight and short as possible to maximize performance.

Operation Modes

Designed for continuous or intermittent duty in various environments.

  1. Startup: Set speed to minimum. Turn POWER on.
  2. Normal Operation: Adjust speed dial to desired airflow. Monitor sound and vibration.
  3. Reversing (if equipped): Turn power OFF. Switch direction. Wait 30 seconds before restarting.
  4. Shutdown: Turn speed to minimum. Turn POWER off.
  5. Standby: Unit can be left powered with speed at zero. For long periods, disconnect power.

WARNING! Do not change direction while motor is running. Allow motor to stop completely first.

Safety Features

Thermal Protection: Motor cuts off if overheated; auto-resets after cooling. Overload Protection: Internal circuit breaker protects against electrical overload. Housing Design: Prevents accidental contact with moving parts. Grounding: Mandatory protective earth connection.

Care & Maintenance

Disconnect power before any maintenance. Regular maintenance ensures longevity.

  1. Monthly: Inspect for dust/debris buildup. Clean intake grille and housing exterior with dry cloth.
  2. Quarterly: Check mounting hardware tightness. Inspect impeller for damage (requires cover removal).
  3. Annually: Lubricate motor bearings if not sealed (see motor plate). Check electrical connections.
  4. As Needed: Replace air filter if used. Clean impeller blades if contaminated.

CAUTION! Do not use water, solvents, or compressed air to clean electrical components. Use only dry, lint-free cloth.

Troubleshooting

SymptomPossible CauseCorrective Action
Unit does not startNo power / Tripped breakerCheck power supply and circuit breaker. Ensure POWER switch is ON.
Reduced airflowClogged filter / Duct obstructionClean or replace intake filter. Inspect and clear ductwork.
Unusual noise/vibrationLoose parts / Damaged impellerTighten all fasteners. Inspect impeller for damage or imbalance.
Motor overheats/cuts outBlocked airflow / High ambient tempEnsure intake/exhaust are clear. Reduce speed or improve ventilation.
Speed control not workingFaulty dial / Wiring issueCheck control dial connection. Consult wiring diagram.

Reset: If overload trips, reduce load, allow cooling, press RESET button.
