○ Approvals

The metal face side should be placed tightly with the installation surface of the equipments to be controlled when the installation of contact temperature detection is adopted.

Don’t distort the shell cover in installation to avoid performance decrease.

Don’t let liquid go into the temperature controller to avoid the electric reliability.

Please connect the cable correctly in accordance with the instruction signs.

Keep the product in clean dry warehouse at good ventilation and free of corrosive gas and with relative humidity less than 90% and environment temperature under 40℃.
