System Explanation
In this installation, fluid is drawn from the
supply container into one of the manifold in-
lets. With the fluid needle valve (N) closed,
that fluid is pumped through side B and out
to the tray . Opening the air side needle
TRAY
valve (P) draws air into the fluid return line
so less fluid is returned to the pump (side A)
than is supplied to the tray.
IN FLUID LINE
To circulate the fluid, close Valves P and N.
To lower the fluid level in the tray , close
Valve P and open Valve N.
To raise the fluid level in the tray
Valve N and open Valve P.
This is a basic system. Additional equip-
ment such as solenoids and float valves
can be used for automated systems. See
your distributor for details.
1:1 MIX RATIO (approximate) INSTALLA-
Uses dual inlet and single outlet manifold
See Fig 2 for air line accessories
System Explanation
Mixes two fluids, such as antifreeze and water in an ap-
proximate 1:1 ratio. Minimum fluid output should be in incre-
ments of 3 quarts to ensure an approximate 1:1 mix ratio.
Lower output quantities may result in unequal mix ratio.
