• 2006/42/EC machine Directive - Safety prescriptions• 2006/95/EC low voltage Directive - Electricity• EMC 2004/108/EC Directive - Electromagnetic

compatibility

• 2009/142/EC directive• EN 1886 - Air treatment box mechanical performances• EN 60204-1 - Electrical appliances

Moreover, each unit is delivered with an EC standard conformity certifi cate and respects standards below listed:

The ETT packaged unit, delivered ready to operate, is made of aluminium frame & casing, giving an extremely high resistance to the elements (20-year warranty against corrosion). The ETT unit can be installed at ground level (plantroom) or on a roof. GREEN DESIGN involves DECONSTRUCTION: ETT units are 98% recyclable (re-use and recycling rates based on CH 99 RR HPE+).

Each unit, prior to shipment, is checked and tested at the factory, with issue of a test certifi cate.ETT Quality organization is certifi ed ISO 9001 (AFNOR Certifi cate 1994/2016f).

We placed ease of operation at the heart of our units design: • a separated technical section facilitates service and control of the unit and allows measurement and

adjustment during operation.• the BEST controller specifi cally designed for this application, allows great fl exibility of operation and therefore

optimum performance of the ETT unit, it being user-friendly whether it is with local or remote (with remote display, PC or BMS) communication.

• Law: European directive 2008/98/EC of 19th November 2008: - The 26th point: "The polluter-pays principle is a guiding principle at European and international levels.The waste producer and the waste holder should manage the waste in a way that guarantees a high level of protection of the environment and human health".• Energy: ETT, innovator in Heat Transfer solutions.• Aluminium: a good choice for the planet!- aluminium is 100% recyclable and endlessly.- recycling gives 30% of aluminium needs.• Low polluting ETT manufacturing process:- sorting done by job. All wastes are recycled. No paint, no use of water.- ISO 14001 Certifi cation (Environmental Management System).- ETT has been recognized able to manipulate refrigerant fl uid as stipulated by the F-gas Regulation European Directive, and more particularly, the fi fth Article "minimum requirements and the conditions for mutual recognition shall be established in accordance with the procedure referred to in Article 12(2) in respect of training programmes and certifi cation for both the companies and the relevant personnel involved in installation, maintenance or servicing of the equipment and systems covered by Article 3(1)" which are "refrigeration, air conditioning and heat pump equipment".

• An effi cient waste management:- fi ltration: ETT includes "green-designed" air fi lters (sorting frame - grille - media).

Our technical choices have several impacts on the environment:

General description

6 CTA CH HPE+ CEE - 10/2014 - 0.1.0.2.3


Operating modes can be:> Heating> Air conditioner> "Free cooling": cooling with external air, without

thermodynamics

The unit can operate:> In all recycling mode> In all fresh air mode> In mixing mode

The ETT package comprises 2 different sections:1/ a separated technical section including hydraulic components, electric board and regulating

elements.2/ an internal section for air change and handling.

Aluminium frame and casing assembly designed with:- a rigid, compact, lightweight and weather-resistant casing that includes a 20-year corrosion-resistant warranty on

frame & casing.- a watertight fl oor with drainage outlets located at the border of the unit and linked to rubber siphons. - vertical AG3-type aluminium panels and roof. - access through large "easy to remove" panels. Access to components is made through large "easy to remove"

lockable aluminium panels. Doors tightness is ensured by fl exible gasket under compression, providing an ideal elasticity day after day.

- inside acoustic and thermal insulation made by M0 glass wool, 50 mm thickness. The insulation is reinforced in the ventilation section.- fl oor acoustic and thermal insulation made by double skin M0 rock wool, 100 mm thickness. - 2-damper mixing box with motorized fresh air damper with bird proof grid and return air damper ensuring the

desired proportions and optimizing "free cooling" economizer phases. Dampers have class 3 extruded aluminium blades with low pressure drop. The damper frame is made of aluminium.

Principle of operation

7CTA CH HPE+ CEE - 10/2014 - 0.1.0.2.3


Air assembly designed with:- easy-to-remove green-designed fi lters - 98 mm, folded, 95% ASHRAE gravimetric (G4) effi ciency, fouling controlled

by pressure-switch. - free wheeling supply air fan. This technology avoids losses due to pulley-belt transmissions.- motor with:

• reduced kickback during the starting for textile ducts (soft start mode).• maximum rotation speed regulation according to pressure drops on site.• reduced speed operation in free-cooling mode to save energy.

- supply air fan compliant with EuP 2013 / ErP 2015 directives.- internal exchanger: Water change over coil made with copper pipes and aluminium fi ns and frame. This coil can

be supplied with hot or chilled water to ensure a heating or cooling operation.

Electrical assembly designed with:an electrical board that complies with European standards EN 15-100 and EN 60204-01, and includes: - ETT controller with display.- disconnector with lockable external handle to cut in full load.- 400-230-24 volts transformer for control circuits.- fault synthesis with pending dry contact on terminal.- numbered terminal blocks with disconnecting terminals for remote controls or transfers.- internal wiring numbered at both extremities using numbered ferrules.- Ik3 breaking capacity of basis 10 kA.- components protection using circuit breakers.

Control assembly designed with:- one or more BEST-type controllers (Building Energy Saving Technology) especially developed by ETT for this range

of units. Programs update is done once a year in order to add functions requested for some applications and to optimize units electricity consumption. The microprocessor, memory and controllers size are adapted to the chosen applications and options by integrating a program set-up in the factory out of 160 possible confi gurations. The controller is in a plastic box which guarantees a high mechanical protection and reduces electrostatic shocks threats.

- CTN type temperature sensors. Their accuracy and liability have been tested and validated at the factory and on site.

The controller has the following functions:- on / off with remote contact or unoccupancy contact.- on / off according to operating hours (2 slots per day).- fault synthesis with dry contact for transfer on customer system.- 2 setpoints (cooling and heating) according to European directive 2002/91/EC.- security management (fi re thermostat, smoke detector...) and faults management.- "free-cooling" economizer management by analysing internal temperature and comparing return and outside

air temperatures.- out-of-frost restart.- written faults history (no code needed) displaying hour and outside temperature.- unit and auxiliaries operating hours counting.- air quality control with CO2 sensor to optimize the quantity of fresh air to introduce, therefore limiting energy

consumption.

The roof curb provides interfacing between the roof and the rooftop unit. It has been designed for easy assembly on the roof and simplifi ed unit laying.

Adjustable packaged connection roof curb- Compliant with P 84-206-1 French standard (watertight ribbed sheet metal implement).- the packaged AG3 aluminium roof curb is lighter than galvanized steel constructions.- adjustable angles to compensate roof slope. You can ask for other slope percentages (optional). In this case,

please confi rm percentage and slope direction during execution.- sealing string reinforcing tightness and insulation up to 100 mm maximum (as stipulated by the directive 2002/91/

EC).- roof curbs with a 145 mm steel tank and a 200 mm insulation maximum height (i.e. maxi H = 345 mm).

Adjustable packaged ventilated roof curb- Compliant with P 84-206-1 French standard (watertight ribbed sheet metal implement).- the packaged AG3 aluminium roof curb is lighter than galvanized steel constructions.- adjustable angles to compensate roof slope. You can ask for other slope percentages (optional). In this case,

please confi rm percentage and slope direction during execution.- 200 mm ventilated air space conforming to French standards for public buildings. 4 (or 6) feet fi xed by bolting and

tightness guaranteed with foam gasket on supply air and return air ducts frames.- sound insulation is ensured by an air space which considerably limits the noise below the unit.- 200 mm length double skin insulated supply and return air ducts connections, with an aluminium external

mechanical protection.- cable pipes below the unit for power supply and hot water coils pipework. - the insulation below the roof curb is ensured with a 25 mm thickness glass wool with a protection veil. The insulation

is fi xed by aluminium clips welded on the sheet metal for a better fastening than other gluing methods. The insulation limits waste and avoids an under-surface condensation.

- sealing string reinforcing tightness and insulation up to 100 mm maximum (as stipulated by the directive 2002/91/EC).

- roof curbs with a 145 mm steel tank and a 200 mm insulation maximum height (i.e. maxi H = 345 mm).- lifting lugs to make the cranage easier.

Adapter interface on existing roof curbBespoke roof curb to be adapted on any type of existing roof curbs or headers according to dimensions sent by the installer (see our particular clauses for this equipment).

Probes connection principle

Nota: - Please note that depending on where you install the probe, the value indicated can change.For that reason, in order to have the most accurate results representing the room air, do not install them:> Close to heat sources (spotlight, cooking appliances, glass wall, chimney)> In drafts zones (close to entrance, stockrooms, openings)> In dead zones (behind shelvings, building angle)> Close to crowded areas (checkout, fi tting rooms)

- Those conditions can disturb measures:

> Probes must not be in the axis of the duct used for their wiring to avoid false air fl ow> Holes for control cables must be different from those for power cables (risk of electromagnetic

interference)
