In the case of recharge the refrigerant for service, calculate the proper amount of refrigerant depending on the piping length on
site.
Example : In the case that FDTN508HES-S with piping length of 15m is fully recharged in service.

Drain piping work
¡
Execute the drain piping by using field purchased parts of pipe, elbow, and grommets, if the drainage work is needed.
Drain elbow (1 pc.)
™
There are 3 holes (ø 20) on the bottom plate of Outdoor
unit for draining condensed water.
™
To guide the condensed water to the gutter it is necessary
to install the unit on the flat base or blocks.
™
Connect the drain elbow as shown in the illustration and
close other holes with grommets.
Drain grommet

Hard vinyl chloride pipe for
general purpose (VP-16)

Calculate the additional charge amount according to Table 1.
Example : In the case that FDTN508HES-S is newly installed with piping length of 40m.

(d) Refrigerant charge
1)
Outdoor unit is pre-charged R-22 refrigerant at a factory as shown in Table 1.
2)
Indoor unit is pre-charged only a small amount of nitrogen gas for prevention of the air entry.
3)
Additional charge on site is required when the pipe length is longer than that of restricted value (Which is varied wirh the
type of Indoor unit) as shown in Table 1.
