Operation
Install properly and DO NOT use this product outside the recommended
operating pressure, temperature and other specification ranges.
Improper use may result in such hazards as damage to the product or
malfunctions which may lead to serious accidents. Local regulations
may restrict the use of this product to below the conditions quoted.
CAUTION
Take measures to prevent people from coming into direct contact with
product outlets. Failure to do so may result in burns or other injury from the
discharge of fluids.
CAUTION
Operate valve slowly and carefully. Opening or closing valves too quickly
may cause water hammer to occur, the impact of which could cause
damage to equipment.
CAUTION
To be performed after installation and before initial operation
Make sure to flush the piping to remove welding slag, metal powder and filings.
Make sure that flange bolts etc. are securely tightened before passing steam/
water through the SR-B.
When conducting the test operation, start with a low water flow rate and gradually
increase the load to normal operating conditions. If you start with a normal operating
load at the outset and there is a leak somewhere in the piping, there is a risk of high-
temp. water, boiler feed water or hot water blowing out.
Startup
Make sure that the boiler feed water/cold water inlet valve (A) and boiler feed
water/hot water outlet valve (B) are open before supplying blowdown/high-
temperature water to the SR-B.
If blowdown/high-temperature water is supplied while the boiler feed water/cold water
inlet valve (A) and boiler feed water/hot water outlet valve (B) are closed, the
pressure inside the coil will increase due to volume expansion, which could damage
the boiler feed water/cold water inlet valve (A) and boiler feed water/hot water outlet
valve (B).
1. Make sure that the body blowdown valve
(D) in the base of the SR-B is closed.
2. Open the boiler feed water/cold water
inlet valve (A) and boiler feed water/hot
water outlet valve (B), allowing
boiler feed water or cold water
to pass through the SR-B. In
cases where either TIC
(temperature control of heated
water) or FIC (flow control of
heated water) is used, start up
the controls.
3. Open any valves downstream
from the blowdown/high-temp.
water outlet valve (C), if any.
4. Open the blowdown/high-
temp. water inlet valve, if any.
A Boiler feed water/cold water inlet valve
B Boiler feed water/hot water outlet valve
