Check periodically in accordance with National or Local regulations, or at least once per year:
• Check impeller, motor, guards for dirt, dust, debris and clean as required.
• Check impeller, motor, guards for damage and repair / replace as required.
• Check free rotation of impeller, motor, bearings without vibration or undue noise.
• Check operating current in accordance with Fan label / nameplate.
• Check motor winding resistance is acceptable.
• Ensure there is no build-up of dirt or debris on motor and impeller which could impede cooling or cause imbalance.
Some S&P fans are supplied with sourced / sub-supplier motors, the motor O + M Instructions will be included with the fan for
extra assistance to Installer. Refer these for further motor guidance.
