Procedure

  1. Flush the lines to remove any foreign matter before you connect the lines to the valve. See Servicing.
  2. Screw each companion flange and gasket onto the inlet and outlet water lines. See Figure 1. The inside of the companion flange is threaded. For flange and gasket kit information, see Table 1.
  3. Mount the V43/V243 valves so that the water flow follows in the direction indicated by the arrow on the V43/V243 casting.
    Note: Mount the V43/V243 valves onto a horizontal water line, with the bellows up.
  4. Secure the inlet and outlet water lines with companion flange and gasket to the inlet and outlet flange connections on the V43/V243 valves with hex bolts and nuts.

  5. Connect a 1/4-inch copper (or UltraCap) tube from the bellows of the V43/V243 valves to the refrigerant line. See Figure 2. In reciprocating compressor applications, make the refrigerant connection as far from the compressor discharge as possible. If possible, make the connection on the outlet side of the condenser.
  6. Manually flush the valve to remove debris. See Servicing.
  7. Put the system into operation under normal operating conditions.
  8. Determine the correct refrigerant operating head pressure for the system. Observe the refrigerant pressure that the high side pressure service gauge indicates.
  9. If necessary, adjust the operating head pressure. See Adjusting the valve.
