JOHNSON CONTROLS
If the cables of the solution pump, refrigerant pump, burner fan, and/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 changing the oil of the
purge pump, be sure to stop the purge operation.
In case of an accident such as death, serious injury, or damage to the machinery, turn OFF
the circuit breaker (MCB1) to stop the chiller-heater immediately.
LEAK TESTING
When leak testing, verify the area is properly ventilated. Failure to do so may result in
suffocation.
ELECTRICAL SHOCK CAUTIONS
Do not touch any switch in the control panel with wet hands; this can cause electric shock.
Do not touch the wiring in the control panel; this can cause electric shock.
Do not touch any part other than the control panel of the machine and the valves described
in the operating manual; this can cause a malfunction and injury.
Apply only the specified source voltage. Application of a different source voltage can cause
a fire and electric shock.
Welding should only be done in certain circumstances. 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 result in electrical shock, injury, and/or damage to the
chiller-heater.
Do not splash water over the machine and its control panel; this can cause an electric
shock.
A warning label for electric shock is pasted at the control panel, solution pump, refrigerant
pump, the terminal box of the vacuum pump motor, and the burner fan motor. Prior to
opening the terminal box, be sure to stop the chiller-heater and turn OFF the main circuit
breaker (MCB1). If not, electric shock may result.
USE OF GAS
Inspect the exhaust duct periodically to check for a gas leak.
Only use the fuel specified on the unit name plate.
Inspect the exhaust duct periodically to check for gas leaks.
If black and white smoke is produced, stop the machine and contact your local Johnson
Controls Service Office for assistance.
Do not block the outer cover suction port or exhaust port. This can cause oxygen
starvation.
WARNING: During service and maintenance work, be sure to turn OFF the main circuit
breaker (MCB1) and follow all required Lockout and/or Tagout procedures. Close the
main valve of the fuel gas line. Failure to close the gas line may cause electric shock or
injury.
WARNING: If you smell gas, do not operate the machine or manipulate the switches un-
til the gas smell vanishes.
