  • Page 51: Vibration Switch

    Cooling Towers A.10.2 VIBRATION SWITCH Vibration switches provided by REYMSA are shock sensitive mechanisms for shutdown of the Cooling Tower fan motors. These switches use a magnetic latch to ensure reliable operation whenever shutdown protection from damaging shock/vibration is desired. As the level of vibration or shock increases an inertia mass exerts force against the latch arm and forces it away from the magnetic latch causing the latch arm to operate the contacts.
  • Page 52: Figure A-107: Vibration Switch Detail

    1/4 turn clockwise (less sensitive). Restart the motor to verify that the vibration switch will not trip on start-up. ▪ At this setting, you should expect the vibration switch will trip when abnormal shock or vibration exist. ▪ Verify the vibration switch sensibility annually to prevent any malfunction.

  • Page 57: Tower Set-Up

    A.11 TOWER SET-UP A.11.1 LEVELING AND TOWER SUPPORTS REYMSA Cooling Towers should always be installed on a level surface and adequately supported. REYMSA recommends supporting Cooling Towers on an isolation pad and a structural base; care must be taken to ensure that the basin sump (the lowest portion of the Tower basin) is completely supported (see Figure A-116).
  • Page 58: Figure A-117: Pipe Connections For A Single Fan Tower

    Also, in case your area experiences extreme cold weather, care must be taken to protect all piping located on the exterior of the building from freezing (refer to section “C.4.1 COLD WEATHER OPERATION”). See Figure A-117, Figure A-118 and Figure A-119 for general scheme of the different connections in REYMSA Cooling Towers.
  • Page 59: Figure A-119: Pipe Connections For A Quadruple Fan Tower (Rt-D)

    Make-up water needs to compensate the water losses due to evaporation, drift and purge. To control make- up water flow, a mechanical float valve is included by REYMSA as a standard feature. A NPT connection is provided and marked as Make-up Water. Electric automatic fill valve with control is available as an optional (refer to section “A.10.4 ELECTRIC WATER LEVEL CONTROL SYSTEM”).
  • Page 60: Wiring

    The equalization connection is used to maintain equal water levels when the system consists on more than one basin (see Figure A-120). REYMSA recommends installing a valve (supplied by others) at the Equalization line to regulate flow and allow Tower isolation. Also see section “A.8 EQUALIZER LINE INSTALLATION”.
  • Page 61: Procedure To Wire The Fan Motor

    Cooling Towers A.11.3.1 PROCEDURE TO WIRE THE FAN MOTOR REYMSA suggest that after extended shut down, the model should be checked with insulations tester prior to restarting motor. 1. To gain access to the motor, remove the fan guard on top of the fan duct.

    If inlet pressure to the mechanical float valve exceeds 50 psi. REYMSA Cooling Towers provides a mechanical float valve as standard (see Figure B-1 or refer to “APPENDIX B: WATER MAKE-UP FLOAT VALVE”); an electric valve for automatic flow control is offered as optional. Use the following instructions to adjust the make-up water mechanical float valve on the basin section of the Tower to produce the highest water level without overflowing the Tower.

    Corrosion is a process of metal dissolution usually by oxidation; this process provokes degradation on the metal surface, creating pits or even holes on it. Corrosion of system components shortens its life, reducing operational reliability. However, since REYMSA Cooling Towers are constructed of FRP, corrosion is not an issue for the tower.
