Operation
The SWAP Valve should be mounted to a suitable
surface using the two standard angle mounting brackets
that are mounted to the valve base.
Line mounting to rigid water pipe in lieu of
bracket mounting is discouraged.
Connect water supply to the 1 or 2-inch NPT(F) Water
Inlet.
Connect shop air to the 3/8-inch NPT(F) Air Inlet with
either a permanent or quick-connect fitting.
Connect the 1 or 2-inch NPT(F) Air-Water Outlet to the
cooling water Supply manifold.
Install the check valve (included) in the return water
line downstream from the Return water manifold
as shown in Figure 2. The check valve will prevent
water from back-flowing into the mold after purging.
Depending on your installation, it may be desirable to
add a check valve to the air inlet ahead of the SWAP
Valve.
In closed loop systems, air separator installation is
recommended to bleed off residual air introduced by the
SWAP Valve. See figure 2.
