Danger

Direct contact with refrigerant can be harmful to
skin.

■

Only work on the refrigerant circuit whilst
wearing safety goggles and safety gloves.

Note

Work on the

refrigerant circuit

must only be

carried out by a qualified

refrigeration engi-

neer

■

Wear suitable protective clothing.

Work on the casing

Danger

Breaking through the knockouts on the back
panel leaves behind sharp edges from the metal
retaining tabs that can lead to life threatening
injuries.

■

Finish and seal the edges appropriately before
installation.

Note

Damage to the surfaces of the casing can lead to cor-
rosion.
