Charging procedure for T-Spectrum & UT units.
Prior to charging, it is necessary to make a rough estimate of the charge requirements of the unit. The correct quantity of
refrigerant required for an installation will depend on the type of unit, the type and number of remote evaporators used, and the
refrigerant line route between the condenser area and the remote evaporators.
The following table will help you to estimate the starting charge for the full system (step 3).
The following drawing refers to the combined length of refrigeration tube for adding refrigerant. This is for the combined total
for 1 metre of length for the three tubes not for each individual tube. Irrespective of suction line size the calculation is the
same.
For example:
In the case of one T-1000R Spectrum, micro-channel 2 zones with one S3 in each zone and a total length of 7
metres of combined refrigerant tubes the starting charge to consider will be:
2.60 + 1 + 1 + (0.130 x 7) = 5.51 kg
