Page 4: 1-Introduction
1-INTRODUCTION The new Water Cassette Series units BREZZA are designed for air conditioning in residential and commercial plants. The installation is indoor and not exposed to ice or extreme temperatures, dust-free environment and not explosive materials. The manufacturer is not responsible in case of incorrect use. The series BREZZA is proposed with traditional AC motors with three speeds and which EC motors with low consumption. -
Page 5: 4- Key Reading Codes
In case where the ceiling is higher than 3m, accordingly there is the need to channel down the air flow, Aertesi provides an accessory panel with adjustable flaps. So you can set manually, for each of the four turns, the orientation of the flow: horizontal (with Coanda effect), or in vertical position. -
Page 6: 5-Technical Details
5-TECHNICAL DETAILS STRUCTURE: made on galvanized steel sheet, thickness 1.00mm. The robust design prevents the vibration and it includes mounting brackets to the ceiling. FRONTAL PANEL: painted plate thickness 0.8mm. The conformation of the baffles ensures a Coanda Effect to the air flow output. As an accessory, you can have the adjustable deflectors to have the Coanda effect or vertical airflow (or intermediate positions). - Page 7 INSULATION: cassette body insulated with cross-linked polyethylene foam 10 mm thick, class B-BL-s2d0 s1d0 according to EN13501-1. Front panel insulated with polyethylene thickness 3mm. ELECTRICAL BOARD: made of galvanized steel plate and positioned on the same side of water connections. CONDENSATE DRAIN PUMP: centrifugal type, equipped with a double level float (on-off pump and alarm) and check valve (to avoid the return of odors from the plughole and reduce the noise power).

All codes kits include two valves, one for each battery in double cassette. The drain pan is supplied as standard with the cassette, without extra-price (ADPB) The cassette have two double 1200x600 kit valves, one for the right battery and one for the left battery. Both kits valves are connected in parallel, the aim is a kit consisting of hoses and TEE brass (see paragraph on accessory Flex2 - Flex4).

Page 19: Flange For Air Delivery Duct (Flma)
11.5- Flange for air delivery duct (FLMA) You can connect up to 3 throws ducted through D.160 collars. The available prevalence is a function of the number of collars connected and the air flow rate. Collars positions are represented in the figure below. 11.6- Flange for external air intake (FLAE-FLAE2) It is possible to connect an external air intake via a D.100 collar. -
