Installation
always use lock-out, tag-out procedures!
Ensure the electrical power is off and the disconnect is locked and tagged
prior to working on the Hydro Kit.
Verify the piping system has been properly evacuated
(<500 ppm), and the system's refrigerant charge is correct
before commissioning and after any repair is made.
Improper system evacuated and/or an improper refrigerant charge may
cause product malfunction.
Do not install the units outside.
There is risk of fire, electric shock, explosion, and physical injury or death.
Do not change the settings of the protection devices.
If the pressure switch, thermal switch, or other protection device is
shorted and forced to operate improperly, or parts other than those
specified by LG are used, there is risk of fire, electric shock, explosion,
and physical injury or death.
Do not store or use flammable gas or combustibles near the
unit.
There is risk of product failure, fire, explosion, and physical injury or death.
replace all control box and panel covers.
If cover panels are not installed securely, dust, water and animals may
enter the outdoor unit, causing fire, electric shock, and physical injury or
death.
always check for system refrigerant leaks after the unit has
been installed or serviced.
Low refrigerant levels may cause product failure, and exposure to high
concentration levels of refrigerant gas may lead to illness or death.
Due to our policy of continuous product innovation, some specifications may change without notification.
