Warranty i | 5 Note: The operator is responsible for ensuring that personnel are instructed and have understood the contents of the operating instructions. If something is unclear, please contact Systemair or its representative. 2.1 Personnel The fan may only be used by qualified, instructed and trained personnel. The persons must know the relevant safety directives in order to recognize and to avoid risks.
| IV-50 EC Warning Suspended loads. ◊ Wear protective equipment during all work in the vicinity of the fan, details see 2.2 Personal protective equipment, page 5. ◊ Do not walk under suspended loads. ◊ Make sure that there is nobody under a suspended load. 4.2 Delivery Each fan leaves Systemair in proper mechanical and electrical condition. The fan should remain in the original packaging until the final delivery to the installation site. 4.2.
IV-50 EC | 7 ◊ Do not stack the fans on top of one another after uncrating. ◊ Use hoisting and/or lifting equipment that is suitable for the weight to be vertically moved. Preconditions: ◊ Store the devices in a clean, dry and vibration-free environment. ◊ Storage temperature should be between –20°C and 60°C. Storage for more than 3 months: ◊ Turn the impeller at least 10 revolutions, once per month. o Please ensure that the impeller is at a different position afterward.

IV-50 EC | 7 Installation 7.1 Safety information Warning Danger from falling fan or fan parts. ◊ Check the surface before installation for load-bearing capacity. ◊ Consider all static and dynamic loads when selecting hoisting equipment and fastening components. ◊ Installation may only be carried out by adequately qualified persons, see Table 1: Qualifications ◊ Wear protective equipment during all work in the vicinity of the fan, see 2.2 Personal protective equipment.
| IV-50 EC o If using Post-Installed Mechanical Anchors (Adhesive), anchors must be tested and evaluated to ACI 355.4 requirements. ◊ If you are mounting to steel or wood frames, you must use vibration isolators. Anchoring: ◊ Contractor to anchor suspended unit to concrete with (1) 3/8-inch diameter concrete anchor capable of resisting 40 lbs (Safety Factor of 4 equals 160 lbs) of tension load with minimum embedment of 2-inch at each of the (4) support points.
IV-50 EC 8 Electrical connection 8.1 Safety information Warning Danger from electrical voltage. ◊ Observe the 5 rules of electrical safety, see 2.3 Five rules of electrical safety. ◊ Prevent the ingress of water into the connection box. ◊ The electrical connection must be carried out by qualified persons, see Table 1: Qualifications. ◊ Wear protective equipment during all work in the vicinity of the fan, see 2.2 Personal protective equipment.
| IV-50 EC 8.4 Motor Controls ◊ The product fan speed can be either: ◊ Option 1: On / off, set to run at maximum speed when powered OR ◊ Option 2: Variable speed, adjusted by an external control signal ◊ See 8.5.1 Connection Diagram - Control voltage for external speed adjust options ◊ Option 1 is the factory setting ◊ Contact Systemair if you wish to use a lower maximum fan speed than factory default without variable speed control.

| IV-50 EC ◊ Operation may only be carried out by adequately qualified persons, see Table 1: Qualifications. ◊ The device may only be operated by people who understand the function and risks and can act accordingly. ◊ Abide by the system-related conditions and requirements of the system manufacturer or plant constructor. 10.2 Preconditions ◊ Ensure access only to persons who can safely handle the device.
IV-50 EC | ◊ WECM / Emerald eZA products have an LED that indicates the motor status and aids in troubleshooting. The opening is located on the rear of the IV fan unit next to the electrical box, under the gasketed screw cap.
| IV-50 EC 11.3 Maintenance Warranty claims can only be made if maintenance work is carried out correctly and written evidence thereof is provided. We recommend regular maintenance intervals to ensure continuous fan operation. These maintenance intervals are specified in the “Activities” table below. In addition, the operator must carry out follow-up activities such as cleaning, replacing defective components or other corrective measures.
IV-50 EC 11.4 | Variable speed fans Important Varying speeds may lead to increased vibrations dependent on the support structure. ◊ Pay particular attention to damage from vibrations. ◊ After commissioning, start with shorter maintenance intervals. ◊ If no damage occurs, adjust the maintenance intervals up to those stated in the operating instructions. ◊ Responsibility for gradual adaptation is with the system operator/installer. 11.
