8. DECOMMISSIONING
STORAGE
Long-Term Storage - If you will not be using the unit for an extended period of time (more
than a few weeks) it is best to clean the unit and dry it out completely. Please store the
unit per the following steps:
1.
Unplug the unit and remove exhaust hose and window kit store with the unit.
2.
Drain the remaining water from the unit.
3.
Clean the filter and let the filter dry completely in a shaded area.
4.
Re-install the filter at its position.
5.
The unit must be kept in upright position when in storage.
6.
Preserving the machine in ventilating, dry, non- corrosive gas and safe place indoor.
ATTENTION:
The evaporator inside the machine has to be dried out before the unit is packed to avoid
component damage and molds. Unplug the unit and place it in a dry open area for days to
dry it out. Another way to dry the unit is turn on the machine, adjust it to low-wind ventila-
tion mode, and maintain this state until the drainage pipe becomes dry, so as to keep the
inside of the body in a dry state and prevent it from mildewing.
WARNING!
Releasing refrigerant into atmosphere is strictly forbidden!
