WARNING
Do not reset this device from a remote location. Because it is difficult to make a safety check
when far from the equipment, there is an increased risk of explosion.
This device is equipped with functions that are extremely important for the safe operation of
combustion equipment. Be sure to follow the instructions stated in this user’s manual.
Check the model number carefully and check that the sequence timing is as specified by the
combustion equipment manufacturer. Installing the wrong model can result in an explosion
hazard.
Connect the load (ignition transformer, solenoid valve, etc.) directly to the output terminals of
this device. If it is not directly connected, combustion safety cannot be ensured.
Before mounting, removing, or wiring, be sure to turn off the power to this device and all
connected devices. Failure to do so may result in electric shock.
Never short-circuit the start contact in order to start and stop this device by switching the
power on and off. This is very important for reliable activation of the self-check circuit at
device startup. Failure to observe this warning could lead to an explosion.
Do not extend the lead wires of the contact reset for more than the allowable length of
10 meters. If the device is reset from a location where it is difficult to check the safety of
combustion, there is a risk of explosion.
CAUTION
For mounting and wiring, follow the instructions in this user’s manual or in manuals provided
by the combustion equipment manufacturer.
All wiring and installation must comply with applicable local electrical codes, ordinances and
regulations.
Do not use unused terminals on the device as relay terminals.
Use this product correctly within the range of the rated specifications stated in the user’s
manual. Not doing so may cause device failure or malfunction.
Always supply electricity at the voltage and frequency stated on the model label of this
device.
Make sure the burner frame is properly grounded in compliance with applicable local
electrical codes, ordinances, and regulations.
Run the high-voltage ignition transformer cable separately and keep it at least 30 cm away
from this device.
Keep power wires and the ignition transformer high voltage cable separate from the flame
detector wiring.
Make sure that ignition transformer high-voltage cables are properly connected to prevent
faulty contact. Faulty contact may generate high-frequency radio waves, causing malfunction.
