nstallation and Initial Adjustment
Note:
If available, follow the mounting instructions of
the equipment onto which the V43 will be
installed. For new installation, a companion
flange and gasket kit (refer to Table 3) is
required to mount the V43 to the water lines.
1. Flush the lines to remove any foreign matter before
connecting the lines to the valve. Refer to the
Servicing section.
2. Screw each companion flange and gasket onto the
inlet and outlet water lines as indicated in Figure 6.
The inside of the companion flange is threaded.
(Refer to Table 3 for flange and gasket kit
information.)
3. Mount the V43 so that the water flow follows in
the direction indicated by the arrow on the
V43 casting.
The V43 is not position sensitive for operation.
However, if the V43 is to be drained during
shutdown, mount the V43 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 with a hex
bolt and nut.

(V43AV Shown)
5. Connect a 1/4 in. copper (or Ecosafe®) tube from
the bellows of the V43 to the refrigerant line as
indicated in Figure 7. If possible, make the
connection on the inlet side of the condenser.
6. Manually flush the valve to remove debris.
(Refer to Servicing section.)
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 indicated at the high side pressure
service gauge.
9. If necessary, adjust the operating head pressure
as instructed in the Valve Adjustment section.
C
heckout Procedure
Note:
Before leaving the installation site, observe at least
three complete operating cycles (bellows open and
close) to verify that all components are functioning
properly. The V43 should be regulating the water flow
at the correct pressure. To adjust the operating head
pressure and water flow, refer to the Valve Adjustment
section.

(V43AV Shown)
Before operating equipment, always manually
flush the valve. Refer to the Servicing section.
