Trap 16 Leakage test and Evacuation Air and moisture remaining in the refrigerant system have undesirable effects as indicated below. 1. Pressure in the system rises. 2. Operating current rises. 3. Cooling(or heating) efficiency drops. 4. Moisture in the refrigerant circuit may freeze and block capillary tubing. 5. Water may lead to corrosion of parts in the refrigeration system. Therefore, the indoor/outdoor unit and connecting tube must be checked for leak tight, and vacuumed to remove incondensible gas and moisture in the system. Preparation • Check that each tube(both liquid and gas side tubes) between the indoor and outdoor units have been properly connected and all wiring for the test run has been completed. Remove the service valve caps from both the gas and the liquid side on the outdoor unit. Check that both the liquid and the gas side service valves on the outdoor unit are kept closed at this stage. Leakage test • Connect the manifold valve(with pressure gauges) and dry nitrogen gas cylinder to this service port with charge hoses. CAUTION: Be sure to use a manifold valve for leakage test. If it is not available, use a stop valve for this purpose. The "Hi" knob of the manifold valve must always be kept close. • Pressurize the system to no more than 3.8 Mpa with dry nitrogen gas and close the cylinder valve when the gauge reading reached 3.8 MPa Next, test for leaks with liquid soap. CAUTION: To avoid nitrogen entering the refrigerant system in a liquid state, the top of the cylinder must be higher than its bottom when you pressurize the system. Usually, the cylinder is used in a vertical standing position. 1. Do a leakage test of all joints of the tubing(both Indoor unit and outdoor unit) and both gas and liquid side service valves. Bubbles indicate a leak. Be sure to wipe off the soap with a clean cloth. 2. After the system is found to be free of leaks, relieve the nitrogen pressure by loosening the charge hose connector at the nitrogen cylinder. When the system pressure is reduced to normal, disconnect the hose from the cylinder.

Connect the charge hose end described in the preceding steps to the vacuum pump to evacuate the tubing and indoor unit. Confirm the "Lo and Hi" knob of the manifold valve is open. Then, run the vacuum pump. The operation time for evacuation varies with tubing length and capacity of the pump. The following table shows the time required for evacuation. Indoor unit Outdoor unit Required time for evacuation when 30 gal/h vacuum pump is used If tubing length is longer If tubing length is less than 10 m(33 ft) than 10 m(33 ft) Gas pipe 30 min. or more 60 min. or more 0.07 kPa or less 2. When the desired vacuum is reached, close the "Lo and Hi" knob of the manifold valve and stop the vacuum pump. Manifold valve Finishing the job 1. With a service valve wrench, turn the valve stem of liquid side valve counter-clockwise to fully open the valve. 2. Turn the valve stem of gas side valve counterclockwise to fully open the valve. 3. Loosen the charge hose connected to the gas side service port slightly to release the pressure, then remove the hose. 4. Replace the flare nut and its bonnet on the gas side service port and fasten the flare nut securely with an adjustable wrench. This process is very important to prevent leakage from the system. 5. Replace the valve caps at both gas and liquid side service valves and fasten them tight. This completes air purging with a vacuum pump. The air conditioner is now ready to test run. 18 Lo Pressure gauge Hi Open Vacuum pump Open Test running ENGLISH Test running 1. PRECAUTIONS IN TEST RUNNING • The initial power supply must provide at least 90% of the rated voltage. Otherwise, the air conditioner should not be operated. CAUTION ① For test run, carry out the cooling operation firstly even during heating season. If heating operation is carried out firstly, it leads to the trouble of compressor. Then attention must be paid. ② Carry out the test run more than 5 minutes without fail. (Test run will be cancelled 18 minutes later automatically) • The test run is started by pressing the room temperature checking button and down timer button for 3 seconds at the same time. • To cancel the test run, press any button. CHECK THE FOLLOWING ITEMS WHEN INSTALLATION IS COMPLETE • After completing work, be sure to measure and record trial run properties, and store measured data, etc. • Measuring items are room temperature, outside temperature, suction temperature, blow out temperature, wind velocity, wind volume, voltage, current, presence of abnormal vibration and noise, operating pressure, piping temperature, compressive pressure. • As to the structure and appearance, check following items. □Is the circulation of air adequate? □Is the draining smooth? □Is the heat insulation complete (refrigerant and drain piping)? □Is there any leakage of refrigerant? □Is the remote controller switch operated? □Is there any faulty wiring? □Are not terminal screws loosened?

Air conditioners should not be installed in areas where corrosive gases, such as acid or alkaline gas, are produced. 2. Do not install the product where it could be exposed to sea wind (salty wind) directly. It can result corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient performance. 3. If outdoor unit is installed close to the seaside, it should avoid direct exposure to the sea wind. Otherwise it needs additional anticorrosion treatment on the heat exchanger. Selecting the location(Outdoor Unit) 1) If the outdoor unit is to be installed close to the seaside, direct exposure to the sea wind should be avoided. Install the outdoor unit on the opposite side of the sea wind direction. Sea wind Sea wind 2) In case, to install the outdoor unit on the seaside, set up a windbreak not to be exposed to the sea wind. Windbreak • It should be strong enough like concrete to prevent the sea wind from the sea. • The height and width should be more than 150% of the outdoor unit. Sea wind • It should be keep more than 70 cm of space between outdoor unit and the windbreak for easy air flow. 3) Place with fluent water draining • Install at a place with fluent water draining to prevent damage from localized heavy rain and avoid frequent flooded area. • Periodic ( more than once/year ) cleaning of the dust or salt particles stuck on the heat exchanger by using water Installation Manual 23 ENGLISH Installation Guide at the Seaside Installation Guide at the Seaside Model Designation U U 24 W U 4 2 Serial Number Chassis name Indoor / Outdoor Detailed product type W : Inverter outdoor WH : High COP Inverter outdoor H : High COP indoor units L : Low static Nominal Capacity EX) 9,000 Btu/h Class ➝ '09' 24,000 Btu/h Class ➝ '24' Type U : Outdoor units T : Cassette B : Duct V : Floor-ceiling Q : Console P : Floor standing Model Type U : Universal model C : Common Indoor unit for Universal and Multi Airborne Noise Emission The A-weighted sound pressure emitted by this product is below 70 dB. ** The noise level can vary depending on the site. The figures quoted are emission level and are not necessarily safe working levels. Whilst there is a correlation between the emission and exposure levels, this cannot be used reliably to determine whether or not further precautions are required. Factor that influence the actual level of exposure of the workforce include the characteristics of the work room and the other sources of noise, i.e. the number of equipment and other adjacent processes and the length of time for which an operator exposed to the noise. Also, the permissible exposure level can vary from country to country. This information, however, will enable the user of the equipment to make a better evaluation of the hazard and risk.
