Safety precautions
SEVERE WARNING SIGNS
Installation must be performed by a qualified installer .
f
If the user installs a product improperly on their own, it may cause refrigerant leakage and lead to electric shock or fire .
Install the unit in a place where it is strong enough to hold the product weight .
f
When installed in place where it is not strong enough to withhold the product weight, the unit could fall and cause injury .
Do not put any product or object under the DVM Hydro unit / Hydro unit HT .
f
Water from the DVM Hydro unit / Hydro unit HT may fall and cause fire or loss of property .
Electric work must be done by qualified persons, complying the national wiring regulations and installed according to the
instruction stated in the installation manual with leased circuit .
f
Insufficient capacity or improper installation of the power circuit may result in electric shock or fire hazard .
Use the specified wires for wiring . Make sure that the wires are firmly connected and firmly fixed to the terminal connections
so that no external is applied to the wires .
f
Improper connection or fixation may cause fire .
Neatly arrange the wires in the electrical parts to make sure that electrical cover is closed securely without any gap .
f
If the cover is not properly closed, heat may generate on the electrical terminal and cause electric shock or fire .
Make sure to use the provided or specified parts with the specified tools for installation .
f
Failing to do so may cause product failure, refrigerant leakage, fire or electric shock .
In any case of refrigerant leakage, make sure to ventilate .
f
If the refrigerant gas comes in contact with fire, harmful gas will be generated .
f
Make sure that the refrigerant gas does not leak after completing the installation . If the refrigerant gas of the indoor unit
leaks and comes into contact with the fan heater, space heater or stove, harmful gas will be generated .
Make sure to perform grounding work .
f
Do not connect the ground wire to a gas pipe, water pipe, lightning rod or telephone grounding . Improper grounding
could cause electric shock .
Do not install the product in a place where it is or might be exposed to inflammable gas leakage .
f
When the gas leaks and gets accumulated around the product, it may cause fire .
Installation work must be done according to the instruction in this installation manual .
f
Improper installation may cause water leakage, electric shock or fire .
When connecting the power supply, make sure the connection is tight and the connection does not have any dust, blockage,
or loose parts .
f
If there are dusts, blockage or loosened part on the power supply connection, it can cause electric shock or fire . Also,
replace the connection if it is loose .
When installation is in progress, check the following before operating the product .
f
Make sure pipes are properly connected without any leakage .
f
When there is leakage on the connected part, air may get in and cause abnormally high pressure state which may lead to
pipe explosion and personal injury .
Do not assemble the power cord on your own, use two cables together to extend the cable length or connect the power to a
multi consent connected with other products .
f
Bad connection, isolation and over voltage may cause fire or electric shock .
Cut-off the main power supply before electrical installation of DVM Hydro unit / Hydro unit HT .
f
Potential risk or electric shock .
