Disassembly
When disassembling or removing the product, wait until the internal
pressure equals atmospheric pressure and the surface of the product
has cooled to room temperature. Disassembling or removing the
product when it is hot or under pressure may lead to discharge of fluids,
causing burns, other injuries or damage.
CAUTION
It is a recommended practice to dismantle and inspect the DR8 once a year for
preventive maintenance purposes. It is especially important to perform an
inspection immediately after the initial run of a new line or before or after
equipment such as a heater is out of service for a long period of time.
(Installation, inspection, maintenance, repairs, disassembly, adjustment and valve
opening/closing should be carried out only by trained maintenance personnel.)
Remove all steam from the piping (both upstream and downstream).
Wait for the body to cool before attempting to remove the DR8 from the line.
Then remove the
DR8
from the piping, and secure it in a vise to perform the
inspection.
Disassembling the Adjustment Section
Loosen the cap and the locknut first. Loosen the adjustment screw completely
and remove the body clamp.
