(3)
NEVER switch off the main power source during operation of the absorption chiller
heater.
Besides, do NOT switch off even the machine is not operated except for a special case.
(4)
Do NOT touch the switches in the control panel with wet hands. It may cause an electric shock.
(5)
NEVER touch the combustion system. It may cause an oxygen
poor accident due to improper
combustion or a fire accident.
(6)
Do NOT touch the electrical wiring in the control panel. It may cause an electric shock.
(7)
Do NOT touch the high voltage wiring of the ignition transformer during operation. It may cause
an electric shock.
(8)
Do NOT touch the absorption chiller
heater as the control panel door is left open. It may cause
a trouble of the electrical instrument or an electric leakage.
(9)
Do NOT insert fingers or a stick into the rotating parts of the fan and pump. It may cause injury.
(10) Do NOT touch the portions where a wa
rming, “CAUTION: High Temperature” is labeled on the
absorption chiller
heater. If you touch the portion, you may burnt.
(11) The high pressure generator, the low pressure generator, the high and the low temperature heat
exchangers, and the high temperature pipes have high temperature. Be careful not to touch
those parts so as not to get burnt.
(12) NEVER stop the operation of the chilled water pump until dilution operation of the chiller
heater
is completed as per the operation sequence to eliminate a possibility of tube damages, etc.
NEVER stop the operation of the cooling water pump as well until it is completed as per the
operating sequence.
3. Cautions in Emergency
(1)
If the vicinity of the absorption chiller
heater should smell of gas or fuel leakage should be
observed while the machines is operating, stop the operation immediately and close the main
fuel supply valve. In such a case happens, contact our service agent to identify the portion of the
leakage and repair it as soon as possible.
(2)
When air
leak into the absorption chiller
heater is detected, check first if the manual service
valve is fully closed. If air
leak is still detected after the check, contact our service agent to
identify the portion of the leakage and repair it as soon as possible.
(3)
If black smoke should generate from the chiller
heater, stop the operation of the absorption
chiller
heater to contact our service agent. If the chiller
heater continues to operate. It may
cause a fire due to improper combustion.
(4)
When there is any danger of a fire, an earthquake and falling of a thunder, stop the operation of
the absorption chiller
heater right away. If you continue to operate the machine, it may case a
fire or an electric chock.
(5)
When the safely devices or the protective devices actuate, remove the cause of their actuation
first and then re
start the absorption chiller
heater. If the machine is kept operating and repeats
start-stop operation without removing the cause, it may cause a fire.
