5.Installing the coupler heat insulation
After checking for gas leaks, insulate by wrapping insulation around the two parts (large and small) of the indoor unit
coupling, using the coupler heat insulation. After installling the coupler heat insulation, wrap both ends with vinyl tape so
that there is no gap. Secure both ends of the heat insulation material using nylon fasteners.
