SECTION 3 – HANDLING, STORAGE, INSTALLATION AND REASSEMBLY
Periodically inspect the strainer for the air purge blow-
er to prevent clogs and an incomplete air purge.
Wear protective gloves and goggles when operating the
chiller-heater.
Do not operate the machine with panel doors open or
removed. Exposure to rainwater or wind pressure can
damage the electrical parts of the unit or cause leakage.
During service and maintenance work, be
sure to turn OFF the main circuit breaker
(MCB1). Follow all required Lockout or
Tagout procedures.
If the cables of the solution pump, refrigerant pump,
air purge blower, or vacuum pump are disconnected
for service and maintenance work, be sure to check the
rotating direction of the pump motor. If not, the chiller-
heater may malfunction.
When you change the oil of the purge pump, be sure to
stop the purge operation.
LEAK TESTING
When leak testing, be sure the area is properly venti-
lated. Failure to do so may result in suffocation.
ELECTRICAL SHOCK CAUTIONS
Do not touch any switch in the control panel with wet
hands. A severe electric shock may result.
Do not touch the wiring in the control panel. Electric
shock may also result.
Do not touch any part other than the control panel of
the machine and the valves described in the operating
manual. If you do, problems or injuries may take place.
Apply only the specified source voltage. Application of
a different source voltage may cause a fire and electric
shock.
Welding should only be done under certain circum-
stances. Be careful not to compromise the integrity of
the vessel. Prior to welding, verify that the electrical
system is grounded properly. Failure to do this can re-
sult in electrical shock, injury, or damage to the chiller-
heater.
Do not splash water over the machine and its control
panel. Severe electric shock may result.
A warning label for electric shock is pasted at the con-
trol panel, solution pump, refrigerant pump, air purge
blower, and the terminal box of the vacuum pump mo-
tor. Prior to opening the terminal box, be sure to stop
the chiller-heater. Turn OFF the main circuit breaker
(MCB1). If not, electric shock may result.
USE OF GAS
If the smell of gas is present, do not operate the ma-
chine, touch the control panel or press any buttons until
the smell of gas is gone.
Inspect the exhaust duct periodically to check for gas
leaks.
Do not block the outer cover suction port or the ex-
haust port. This can cause oxygen starvation.
EXHAUST GAS DAMPER
Exhaust gas dampers are not installed before ship-
ment. They must be installed at the site. See
for information on where to install the
dampers.
EXHAUST GAS TEMPERATURE SENSOR
Exhaust gas temperature sensors are not installed be-
fore shipment. They must be installed at the site. See
for information on where to
install the sensors.
