PRECAUTIONS
The following cautions shall be observed in order to ensure safe operations of the gas/oil direct-
fired absorption chiller
heater.
1.Cautions before Starting Operation.
(1)
Read this manual through before operating the absorption chiller
heater. Especially, understand
the operating procedures of the important operations well prior to their actual operations.
(2)
Do NOT use other fuels than designated in the nameplate of the absorption chiller
heater. The
use of other fuel than designated may cause a fire.
(3)
Do NOT use other power source than designated in the nameplate of the absorption
chiller
heater. The use of other power source than designated may cause a fire or an electric
shock accident.
(4)
Operate the absorption chiller
heater under the designated design working pressure for
chilled/hot water and cooling water. The use of higher pressure than designated may cause
water leakage or burst to result in a short circuit or a burn.
(5)
Do NOT put dangerous flammable liquid like gasoline, thinner, etc. and combustible materials
near the absorption chiller
heater, smoke, duct, chimney and oil tank. They may cause a fire.
(6)
Do NOT block the suction and discharge vents of the casing with obstructions, which may lead
to improper combustion to result in a fire or an oxygen
poor accident.
(7)
Be sure to ventilate the air in the machine room sufficiently. If the air required for combustion is
in short, it may cause an oxygen
poor accident.
(8)
Do NOT put heavy materials on the absorption chiller
heater and the control panel.
It may cause injury, if they fall off.
(9)
Check if the machine room smells of gas or if the fuel is not leaking or if the fuel feeding pipe is
correctly connected with the burner. When it smells of gas or the fuel leakage is observed, do
NOT operate the absorption chiller
heater. Besides, do NOT operate the switches until the smell
of gas goes off. The operation while it still smells of gas or the fuel is still leaking may cause a
fire.
(10) Be sure to indicate on a label or a board that only expert engineers are allowed to operate the
chiller
heater. If there is such a possibility as other persons than expert engineers reach the
absorption chiller
heater, provide a protect fence around the chiller
heater so that they can not
approach to the machine in order to eliminate any cause by which they may get injured.
2. Cautions During Operation
(1)
Do NOT touch any parts of the absorption chiller
heater except for the manual valves and the
control panel of which operation procedures are explained in this manual. If you perform
adjustment of the other parts than explained in this manual, it may cause a trouble of the
chiller
heater or injury.
(2)
Do NOT change the setting points set in advance at the factory for the safely advises and
protection devices. If the absorption chiller
heater is operated set at wrong setting points, it may
cause a machine trouble or a fire.
