DANGER Hazardous voltage can cause electrical shock and death. High speed rotating equipment can cause severe personal injury. Lock out/Tag out to prevent personal injury BEFORE starting ANY service or inspection. Avoid injury. NEVER operate without ALL required safety guards in place. Avoid injury. You MUST read and understand all instructions in this manual BEFORE installing. TABLE OF CONTENTS I. GENERAL A. Unpacking and Handling .............................2 B. Safety Accessories & Instructions...
3. Air Pressure and Suction: In addition to the normal dangers of rotating machinery, the blower can present additional hazards from the suction or pressure created at the blower inlet or discharge. Suction at the blower inlet can draw materials into the blower where they become high velocity projectiles at the discharge and cause severe personal injury or death.
B. Mounting Methods: An Arrangement 4HM blower is an Arrangement 4, direct driven blower without the bottom base under the motor. If the motor being supplied is a foot mounted motor, an angle base must be used to connect the blower to the motor. A C-Face motor can be bolted directly to the housing without using an angle bracket. Most Arrangement 4HM blowers are supplied with an inlet or discharge flange for mounting the blower to some type of equipment.
F. Set Screw and Taper-lock Bushing Torque Values: All blower wheel set screws are tightened to the proper torque prior to shipment. Some wheels may have taper-lock hubs and split, taper-lock bushings to secure the wheel to the motor shaft. NOTE: Check all set screw or taper-lock bushing torques. Forces encountered during shipment, handling, rigging and temperature can affect factory settings. For correct torque values, see Tables 1 and 2 below.
5. Wiring Connections: All wiring connections should be made for the proper voltage and phase as shown on the motor nameplate. Connections should follow the motor manufacturers recommendations as shown on the wiring schematic. This wiring diagram will be located on the outside of the motor, inside of the motor conduit box or on the motor nameplate. Reversing some wires might be necessary to get the correct blower rotation. 6.
IV. INITIAL UNIT STARTUP NOTICE: Failure to complete and document all the following pre-startup and both post-startup checks, listed in sections A (below) and B on page 8, could void all warranties. A. Pre-Startup & Post-Startup Checks: (Check blocks as each step is completed. Retain this for your records.) DATE: ___________________ A1. Pre-Startup Checks Completed By: ___________________________________ A2. 8 Hour, Post-Startup Checks Completed By: _______________________ DATE: ___________________ A3.
B. Vibration: The blower was balanced at the factory to comply with ANSI/AMCA Standard 204-05, Category BV-2. However, rough handling in shipment and/or erection, weak and/or non-rigid foundations, and misalignment may cause a vibration problem after installation. After installation, the vibration levels should be checked by personnel experienced with vibration analysis and vibration analysis equipment. NOTE: The blower SHOULD NOT be operated if the vibration velocity of the fan exceeds 0.
Fig. 3 Vibration Severity Chart V. ROUTINE INSPECTION & MAINTENANCE Periodic inspection of all the blower parts is the key to good maintenance and trouble-free operation. The frequency of inspections must be determined by the user and is dependent upon the severity of the application. BUT, it should NEVER exceed a 12 month period. The user should prepare an inspection and maintenance schedule and make sure it is adhered to.
A. Hardware: All blower and foundation hardware should be checked to make sure it is tight. Wheel set screws or taper-lock bushings should be tightened to the torque values shown in Tables 1 and 2 on page 5. NOTE: If any set screws have come loose, they must be thrown away and replaced. NEVER use set screws more than once. Replace with knurled, cup-point set screws with a nylon locking patch. B. Motor Bearing Lubrication: 1.
Any accessories used in conjunction with the blower should also be inspected to make sure they are functioning within their intended limits and design specifications. The manufacturers maintenance manuals should be referred to for correct maintenance procedures.
VIII. LONG TERM STORAGE INSTRUCTIONS: (Storage exceeding 30 days after receipt of equipment) NOTE: Failure to adhere to these instructions voids all warranties in their entirety. 1. Storage site selection: a. Level, well-drained, firm surface, in clean, dry and warm location. Minimum temperature of 50°F (10°C). b. Isolated from possibility of physical damage from construction vehicles, erection equipment, etc. c. Accessible for periodical inspection and maintenance. 2.
5. General Motor Procedure: If the motor is not put into service immediately, the motor must be stored in a clean, dry, warm location. Minimum temperature of 50°F. (10°C,). Several precautionary steps must be performed to avoid motor damage during storage. a. Use a “Megger” each month to ensure that integrity of the winding insulation has been maintained. Record the Megger readings. Immediately investigate any significant drop in insulation resistance. b. DO NOT lubricate the motor bearings during storage.
IX. LIMITED WARRANTY: Cincinnati Fan & Ventilator Company (Seller) warrants products of its own manufacture, against defects of material and workmanship under normal use and service for a period of eighteen (18) months from date of shipment or twelve (12) months from date of installation, whichever occurs first.
X. PARTS DRAWING: PLEASE NOTE Cincinnati Fan manufactures many models and arrangements with special variations. For that reason, the maintenance manuals contained on our website do not include a parts drawing nor the completed blower or fan specifications on page 1.
