• All AHU additional refrigerant calculations must be completed by BDT. The calculation is based
on the AHU coil volume (BDT has this data).
• Additional refrigerant can be charged into the system while under a vacuum. In some situations
the system will equalise to the bottle pressure before all of the additional refrigerant is in the
system. The remaining refrigerant can be charged in to the low side of the system while it is
running on either heating or cooling during the initial commissioning process.
• Any additional refrigerant must be liquid charged into the system.
• Additional refrigerant levels should be noted on each outdoor unit.
