Periodic Inspection Procedure for the Outdoor Unit
When periodically inspecting the outdoor unit, follow the safety precautions given below.
Also, make the customer aware that the outdoor unit is under periodic inspection, using "Under
Periodic Inspection" notices attached to the indoor remote control units and power breakers.
[Basics]
Safety precautions
Warning
• Turn off the power to the outdoor unit.
Otherwise you may get an electric shock or be caught or jammed in rotating parts when the
unit is inadvertently operated from a remote control unit.
When inspecting the outdoor unit with the power ON is unavoidable, everyone must be
warned and made aware that the outdoor unit is under inspection.
• After turning off the power to the outdoor unit, make sure that none of the LEDs on the
outdoor unit's circuit boards are lit.
Even though the main power has been turned OFF, attempting to access the circuit boards
with any LED lit could result in an electrical shock due to electricity remaining in the circuit.
• Close the fuel gas cock.
Otherwise a gas leak may occur when you replace fuel system parts.
• The cooling water remains hot for some time after the engine is stopped. Do not attempt to
open the radiator cap until the cooling water temperature is low enough.
Otherwise the cooling water may spout out, possibly resulting in a burn.
Caution
• The outdoor unit has various fluids that remain hot for some time after it stops operation, such
as the cooling water and engine oil. Take care when draining such fluids.
• Take care not to touch parts that remain hot for some time after the unit is stopped.
Safety precautions for inspection
• After replacing a part, any parts (such as harnesses/cables and hoses) that were connected
with the old part must be connected to the new part by exactly restoring the original path,
clamping method, position, and so on. They must not contact edges or vibrating areas.
• Take care not to spill engine oil, cooling water, and so on.
