1. INTRODUCTION
1.1 General
The new FLO DCI INVERTER split wall mounted range has expanded, comprising the
following RC (heat pump) models:
● FLO 18
● FLO 21
●FLO 24
● FLO 30
The indoor FLO units are available as LED or LCD display types, featuring esthetic
design, compact dimensions, and low noise operation.
1.2 Main Features
The FLO DCI series benefits from the most advanced technological innovations,
namely:
● DC inverter technology.
● R410A.
● High COP.
● Pre-Charged units up to the max’ allowing tubing distance.
● Networking system connectivity.
● A dry contact for clock or power shedding functions (configurable).
● Base heater connection.
● Cooling operation at outdoor temperature down to -10°C.
● Heating operation at outdoor temperature down to -15°C.
● Supports Indoor Air Quality features, such as – Ionizer and Active Electrostatic Filter.
● Indoor large diameter cross flow fan, allowing low noise level operation.
● Bended indoor coil with treated aluminum fins and coating for improved efficiency.
● Easy access to the interconnecting tubing and wiring connections, so that removing
the front grill or casing is not necessary.
● Refrigerant pipes can be connected to the indoor unit from 5 different optional
directions.
● Automatic treated air sweep.
● Low indoor and outdoor noise levels.
● Easy installation and service.
