WATER PIPING AND CONTROLS
STANDARD UNIT
- MANUAL SHUT OFF VALVE (WV) IS OPENED.
- MANUAL DRAIN VALVE (DV) IS CLOSED.
- FLOAT VALVE (FV) ALLOWS FRESH WAER TO ENTER RESERVOIR.
- WATER PUMP (WP) WILL START AS SOON AS FLOAT SWITCH (FL)
CLOSES. IF WATER IS TOO LOW PUMP WON'T RUN, WATER PUMP (WP) SHOULD BE WIRED SO THAT PUMP
CANNOT RUN WITHOUT BLOWER MOTOR IN OPERATION.
- BLEED-OFF (BO) TO PREVENT SCALE FORMATION, A BLEED-OFF AT
THE RATE OF 3-6% IS REQUIRED. THE EXACT AMOUNT WILL DEPEND ON THE pH AND HARDNESS OF THE
WATER, AND THE INTENSITY OF EVAPORATION.
- UNIT CAN BE USED WITH BLOWER ON AND EVAPORATIVE COOLER PUMP
OFF.
OPTIONAL AUTOMATIC DRAIN VALVE KIT
Adds water conservation solenoid valve, solenoid drain
valve and adjustable 24 hour timer. Replaces constant bleed-off sy stem to provide
periodic sediment and hard water deposit removal.
OPTIONAL AUTOMATIC DRAIN VALVE PLUS FREEZE
PROTECTOIN KIT
Adds motorized drain valve, adjustable 24 hour timer,
outdoor freeze protection thermostat and indoor solenoid 3-way fill valve. Replaces
constant bleed-off system and maintains an empty reservoir during freezing weather
preventing ice expansion damage to water system and pump.
