* E – Electronic / Remote control Type.
* M –Electro Mechanical control.
The split type units consists indoor and outdoor unit, interconnected by a flexible hose.
The mobiles indoor units are equipped with four castors for easy mobility.
The electronic models are equipped with a Microprocessor control system, giving the
user a choice of local or remote control operation, as well as precise temperature
setting and control,
1.2 Main Features
The Mobile series benefits from the most advanced technological innovations, namely:
•Easy mobility.
•Easy installation, (no spacial installation is Required).
•R410A .
• Microprocessor control (Electronic model only).
•High COP.
•Automatic vertical treated air sweep (Electronic only).
•Pre charged refrigerant system.
•High reliability quick connectors for split models which enables temporary separation
between indoor and outdoor units for a fix installation type (optional).
•Compact dimensions.
1.3 Filtration
The Mobile series presents several types of air filters:
•Easily accessible, and re-usable pre-filters (mesh)
•Carbon and electrostatic filter (optional)
