Page 2 O&M Supplement Variable Frequency Drive Lock‐out Notification SAFETY PRECAUTIONS: Qualified personnel should use proper care, procedures and tools when maintaining the Fan/Drive System in order to prevent personal injury and/or property damage. Identify and Lock‐out Harmful Resonant Frequencies A Variable Frequency Drive (VFD) fan system, unlike traditional fixed‐speed systems, is designed to operate between 25% (15Hz) and 100% (60Hz) speeds, which creates an opportunity for operation where resonant frequencies exist. Sustained operation at resonant frequencies may lead to excessive vibration, fatigue of structural components, and/or drive system noise and failure. Owners and operators must anticipate the existence of resonant frequencies and lock out frequencies during start‐up and commissioning in order to prevent drive system operational problems and structural damage. As a part of the normal start‐up and commission processes, resonant frequencies should be identified and locked‐out in the VFD’s software. The unit’s supporting structure, external piping, and accessories contribute to the overall harmonic make‐up and stiffness of the system. The choice of VFD will also have a significant influence on how the system behaves. Consequently, not all resonant frequencies can be determined in advance at the manufacturer’s factory during final inspection and testing. Relevant resonant frequencies (if they occur) can only be identified accurately after the installation in the system. To check for resonant frequencies in the field, a run‐up and run‐down test must be performed. Additionally, VFD carrier frequencies should be adjusted to best align the VFD with the electrical system. Refer to your drive’s start‐up procedures for additional information and instruction. The procedure of checking for resonant frequencies requires stepping through the VFD’s operating range at (2) Hz intervals from the lowest operating frequency to full speed. At each step, pause long enough for the fan to reach steady‐state. Note changes in unit vibration during this time. Repeat from full speed to minimum speed. Should vibration‐inducing frequencies exist, the run‐ up and run‐down test will isolate the resonant frequencies which then must then be locked‐out in the VFD programming. Page 1 of 1 ...

This includes piping, ductwork, conduit, and electrical connections. These items must be flexibly attached to the Evapco unit so as not to transmit additional loads to the equipment as a result of seismic or wind forces.
Page 8 Operation and Maintenance Instructions 10. Visually inspect the fan blades. Blade clearance should be approximately 3/8” (1/4” minimum) from tip of blade to the fan cowl. The fan blades should be securely tightened to the fan hub. 11. If any stagnant water remains in the system including “dead legs” in the piping, the unit must be disinfected prior to the fans being energized.

Page 12: Fan System
Feed grease slowly into the bearings or the seals may be damaged. A hand grease gun is recommended for this process. When introducing new grease, all grease should be purged from the bearings. Most EVAPCO units are supplied with extended grease lines to allow easy lubrication of the fan shaft bearings as shown in Table 1.
Page 13: Fan Shaft Sleeve Bearings - (4ʼ Wide Ls Units Only)
------------------ Table 2 – Sleeve Bearing Lubricants All bearings used on EVAPCO equipment are factory adjusted and self aligning. Do not disturb bearing alignment by tightening the sleeve bearing caps. Oil drippage may result from over-oiling or from using too light of an oil. Should this condition persist with correct oiling, it is recommended that a heavier weight oil be used.
Page 14 Operation and Maintenance Instructions On induced draft belt driven units provided with externally mounted motors (3, 4, 8, 8.5 and 17 foot wide units) and LS and PM Style forced draft units, both J-type adjustment bolts on the adjustable motor base should have an equal amount of exposed thread for proper sheave and belt alignment.
Page 15: Gear Drives
Operation and Maintenance Instructions Gear Drives Induced draft units with gear drive systems require special maintenance. Please refer to the gear manufacturers recommended maintenance instructions. These will be enclosed and shipped with the unit. Air Inlet Inspect the air inlet louvers (induced draft units) or fan screens (forced draft units) monthly to remove any paper, leaves or other debris that may be blocking airflow into the unit.

Applications using a VFD for capacity control must also use an inverter duty motor built in compliance with NEMA standard MG-1. This is an available option from EVAPCO.

Operation and Maintenance Instructions Recirculated Water System – Routine Maintenance Suction Strainer in Cold Water Basin The pan strainer as shown in Figures 8, 9, 10 and 11 should be removed and cleaned monthly or as often as necessary. The suction strainer is the first line of defense in keeping debris out of the system.
