Reservoir Overflow Device
The overflow device is designed to act as an automatic drain for the unit's
reservoir. The assembly is stainless steel with the exception of the drain fitting
®
which is Ryton . The unit can still be drained as normal, but if the level reaches
the middle of the tee it will begin to overflow out the bent tube.
•Drain the unit's reservoir.
•Remove and discard the stop screw from the
bottom of the unit's drain housing.
•Remove the unit's drain fitting.
•Thread the overflow assembly into the
drain housing. (You can remove the
vertical tube assembly from the
Swagelok ® fitting if there is a clearance
issue.)
•After threading the overflow assembly
in as far as it goes, loosen it back out
until the Swagelok ® fitting is at the
top.
•Install one of the two supplied
4-40 x ¼" phillips head screws into
the bottom of the drain housing where
the stop screw use to be. (Make sure this screw is tight so that the assembly
doesn't turn and drain the tank.)
•Reinstall the vertical tube assembly into the Swagelok
•Install the drain fitting into the end of the new assembly - finger tight.
•Install the other supplied 4-40 x ¼"phillips head screw into the bottom of the
overflow assembly. (This prevents the drain fitting from falling off the unit.)
