Page 10: Basic Description Of The Device
Basic description of the device The CoolOut condensing unit is basically an air / refrigerant heat exchanger that removes the heat load (thermal energy) that is taken from the indoor unit as efficiently as possible. The CoolOut unit is optimized for placement on the wall or roof of a building.
Page 11: Correct Usage
3.2 Correct usage CoolOut units are designed to be connected to the Conteg indoor unit. The assembly of these units provides cooling of cabinets with technological equipment (especially IT). CoolOut units must not be used beyond the safety limits. Operating limits: Standard design of CoolOut units.
Page 12: Unpacking And Inspection On Receipt Of The Product
In accordance with the company's terms of delivery, the deliverer is the sole person responsible for damage caused during the transportation of the goods. CONTEG is not liable for any damage caused by the deliverer; however, CONTEG does its best to help its customers in such a situation.
Page 13: Lifting And Transportation
4.2 Lifting and transportation Danger of heavy load falling The capacity of the lifting device must be adapted to the weight of the condensing unit. The load must be placed evenly to prevent tilting. Avoid negligent and dangerous handling. Do not place any other objects on the air-conditioning unit. Check the dimensions of the unit.
Page 14: Installation
• Select a location that allows easy wiring and access to the ductwork. • Avoid locations where flammable gases may escape, produce, flow or accumulate. • Unit must be secured with anchor bolts. • Maintain minimum clearances from walls. 5.2 Basic dimensions Figure 5.1 - CoolOut7 unit...

Page 18: Coolout Unit Installation Procedure
Authorised refrigerant handling personnel will fill R410A refrigerant. Personnel with electrical authorization will install the power and communication cable, see chapter 5.9. Check the cooling function Figure 5.6 – CoolOut7 connection pipe We recommend installing the CoolOut unit with at least 2 people.
Page 19: Refrigerant Piping Between Indoor Unit And Outdoor Unit Coolout7
5.7 Refrigerant piping between indoor unit and outdoor unit CoolOut7 To connect the CoolSeven unit, use a refrigerant pipe with an outside diameter of: Liquid – 1/2“ diameter, wall thickness min. 1 mm. 12 mm wall thickness min. 1 mm.
Page 20: Connecting The Refrigerant Piping And Filling With Refrigerant
5.8 Connecting the refrigerant piping and filling with refrigerant CoolOut outdoor units are ready to be connected to Conteg indoor units. The connection pipe on the outdoor CoolOut unit is brazed to eliminate refrigerant leaks. The brazed joint is not limited by ambient temperature and the tightness of the joint is guaranteed even for very low outdoor temperatures.
Page 21: Disassembly Of Covers Before Brazing
Disassembly of covers before brazing 5.8.1 • Front cover – 7x screw M5x10, head with 3 mm Allen. Figure 5.7 –CoolOut7 front cover • Rear cover – 2x screw M5x10, head with 3 mm Allen. Figure 5.8 –CoolOut7 rear cover...
Page 22: Brazing
Brazing 5.8.2 After removing the covers, the connection points are accessible. Insert the prepared piping into the connection points on the indoor and outdoor unit. Start soldering on the indoor unit to prevent any flue gases from entering the data room through the piping. Cover the ball valves with a wet cloth, this will cool them during the brazing process.
Page 23: Refrigerant Circuit Tightness Checks
Figure 5.9 – CoolOut7 pipe connection points Refrigerant circuit tightness checks 5.8.3 After all components are completely connected and before filling the circuit with refrigerant, two leak tests must be performed on the system. These are a pressure test and a vacuum test.
Page 24 • Pressurise the entire circuit to 15 bar via the pressure reducing valve. • Wait 5 minutes; if the pressure does not drop, continue with further testing; if the pressure drops, find one or more leaks using the bubble method, fix them and repeat the procedure •...

Page 26: Vacuum Test
Vacuum test 5.8.5 Before the CoolOut condensing unit can be started up, it is necessary to ensure that unwanted moisture is removed from the refrigeration circuit, which could cause compressor failure in the long term. The evaporation process takes time, it is not sufficient to simply achieve a given vacuum pressure, but it is important that it continues for a certain period of time.
Page 27: Refrigerant Filling
The remaining amount of refrigerant can be replenished during operation. During operation, add refrigerant only to valve no.2. Type Refrigerant quantity * CoolOut7 4,2 kg * refrigerant quantity up to 30 m of pipes For each additional metre, 0.035 kg is added Maximum pipe length between indoor and outdoor unit is 75 m.
