Manage off cycle migration
Charge limits are defined in the table below :
***Pump-down cycle
By decreasing pressure in the sump, pump down
system:
• evacuates refrigerant from oil
• set the sump saturating pressure much
lower than ambiance temperature and due
to that, avoid refrigerant condensation in the
compressor.
Pump-down must be set higher than 1.7bar(g)
(25 psig).
For more details on pump-down cycle see
section “Control Logic”.
**** External non-return valve is only for
DSH090-105-120-140-161-184.
DSH240-295-381-485 have integrated internal
non-return valve
