cloth. Do not use aggressive or abrasive cleaning agents or
solvents.

all electric current to the outdoor unit. The isolator switch
will be located near the outdoor unit. (see §8.2 and §8.8.1).

► Dry nitrogen is the only substance permitted for tracking
leaks and pressure testing.
► Cleaning the outdoor unit with flammable or combustible
substances is not permitted as it can pose a possible fire
hazard.
