V46 Pressure-Actuated Water-Regulating Valve Product Bulletin8
Mounting
Flush water lines to clear any foreign matter that may
interfere with valve operation. Mount valves vertically
on the inlet side of the condenser with spring housing
up. If it is necessary to keep the condenser flooded
with coolant, the valve can be mounted on the outlet
side. When mounting the valve in a position other than
vertical, follow the instructions of the equipment in
which the valve will be installed. Make refrigerant head
pressure connection to bellows. If additional capillary
tubing is required, use 1/4 in. O.D. tubing or larger.

CAUTION: Risk of Environmental and
Property Damage.
Coil and secure excess capillary tubing
away from contact with sharp or abrasive
objects or surfaces. Vibration or sharp or
abrasive objects in contact with capillary
tubes can cause damage that may result
in loss of element charge, which may
result in damage to the environment or
property.
!
CAUTION: Risk of Environmental and
Property Damage.
Avoid sharp bends in the capillary tubes.
Sharp bends can weaken or kink capillary
tubes, which may result in refrigerant
leaks or restrictions of flow.
