SAMSUNG Electronics

2. When refill oil into the system.
Margin of Oil in the Comp
When refill oil into the system.
Model
■ The module of DVM Plus 2, DVM Plus 3, and
DVM Plus 3 HR outdoor unit
when more then 2 outdoor units are assembled
as one modular system
Reason
To enhance the reliability of the compressor at the severe heating condition
No problem

3. Additional amount of oil
Margin of Oil in the Comp
Compatibility of oil 1
MOBIL
EAL ARCTIC 22CC (Filed supply) 2
UNIQEMA
EMKARATE RL 32 CF (Field supply)
Additional amount of oil
More oil into the system
500 cc / each compressor
Example
EX) 34HP system (14HP+10HP+10HP)
All comps : 3 comps from 14HP+ 2comps from 10HP and 2comps from 10HP
It needs to be charged about cc (7 comps * 500CC) of oil into the system ADDITIONALLY
