Technical Data
General Description
The Super Slim Hydronic Cassette makes each served area an independent controlled temperature zone to suit
diverse requirements.
Construction
Casing is constructed of durable flame resistant acrylonitrile-butadiene-styrene (ABS) plastic. RAL9010 fascia is
constructed of high-impact polystyrene.
Chilled water coil
Coils are constructed with seamless copper tubes and headers. The tubes are mechanically expanded into
corrugated aluminum fin material for a permanent primary to secondary surface bond. Coils are tested under
water at 25 Bar and recommended for operation at 8 Bar. Coils include manual air vent and water purge.
Blower and Motor
The unit incorporates only specially designed and tested EC motors, allowing the blower wheel to provide
optimum performance in airflow-efficiency and quiet operation.
Filters
Washable, easy-to-remove, fine mesh air filters are standard to all high-wall models. Tabs located on the front of
the unit can be unsnapped, allowing the filter to be easily slid downward and removed. No tools are required,
nor any dismantling of the equipment.
Air Grille Distribution
The unit is equipped with both deflector blades and independent directional vanes, enabling supply air to be
automatically distributed, and air flow and direction to be customized.
Condensate pump
A condensate pump is fitted to carry water out of the unit. The pump is fixed to a mounting bracket. The pump
can be withdrawn from the bottom after removing the front panel. A float switch is fitted to stop the cooling
action when the pump become blocked or failed.
Microprocessor controls (EC-TOTAL type)
The PCB (printed circuit board) microprocessor control board relays control the operation of the indoor-fan motor,
water valves (ON/OFF or modulating) and electric heater, to maintain room conditions at a user-defined set point.
Temperature settings, fan speeds and other control functions can be changed by the infrared handset or wired
wall pad.
Electro-mechanical controls (EC-FLEXI type)
A 230VAC signal from the thermostat which working power is from L and N or from indoor room to terminal
H/M/L supplies power to the blower motor. When H (H/M/L) is powered ON, the stepping motor is working and
open the louver at maximum position. When H (H/M/L) is powered OFF, the stepping motor will close the louver.
The condensate pump will run continuously, as long as coil temperature is less than 15°C. Alarm interlock relay is
for unit failure notification. Normally open or normally closed contacts are available for field connection.
