NOTE: GAS CONTENT
If the length of pipe in the heat pump unit generates a dif-
ference between the winter and summer gas content
greater than the quantities indicated in the table, include a
supplementary liquid receiver in the liquid pipe.
INTAKE PIPING
Flared couplings are used for all models.To connect, proceed
as follows:
1. Prepare the end of the pipe, creating the correctly shaped
flare.
2. Connect the prepared pipe to the intake pipe shut-off
valve using two spanners as shown in the figure below.
Liquid piping
Flared couplings are used for all models.To connect, proceed
as follows:
1. Prepare the end of the pipe, creating the correctly shaped
flare.
2. Connect the prepared pipe to the liquid pipe shut-off
valve using two spanners as shown in the figure below.
NB: The use of a flare connected directly to the piping lim-
its impurities inside the pipe. All pipes must be perfectly
clean (clean piping with nitrogen or dry air before con-
necting to the two units) and free from moisture to allow
efficient venting.
