Installation

Mechanical Equipment:

The fluid cooler is designed to operate at full speed and half speed. Warranty is void if the tower is operated at speeds which cause damaging vibrations to the tower and associated equipment. When utilizing a variable frequency drive, the tower must be tested across the full range of speeds and checked against CTI guidelines for ex- cessive vibration. Speed ranges not meeting these guidelines must be locked out in the VFD.

Always shut off electrical power to the tower fan motor prior to performing any maintenance on the tower. Any electrical switches should be locked out and tagged out to prevent others from turning the power back on.

1.If equipped, check oil level in accordance with the Geareducer User Manual for the Geareducer. (Although the Geareducer was filled to the proper level at the factory, tipping during shipment and hoisting may have caused some loss of oil.) If oil is required, fill Geareducer to the proper level with approved lubricant. (See Geareducer User Manual ) Check oil level at the Geareducer or dipstick (standpipe located on fan deck, if so equipped) to confirm that the proper level is indicated.

2.On double-flow models—MHF706 and MHF707—install fan cylinder and two-piece fan guard according to the installation drawing shipped with the fluid cooler.

Improper installation of the fan cylinder and fan guard will destroy the structural integrity of the fan guard. Failure of the fan guard could allow operating or maintenance personnel to fall into the rotating fan.

3.Spin the fan(s) manually to assure that all fan blades properly clear the inside of the fan cylinder. If equipped, observe the action of the coupling (or drive shaft couplings) to be sure that the motor and Geareducer are properly aligned. If necessary, correct the alignment in accordance with the included manual.

For belt drive equipped models observe the action of the sheaves and belts to be sure that the motor is properly aligned with the fan sheave. See Belt Tensioning and Sheave Alignment on pages 22 thru 24.
