CONTENTS PAGE Follow these installation instructions strictly. Incorrect installation may cause water leaks or electrical fires. PRECAUTIONS........................................................................................1 When installing the unit in a small room, keep the refrigerant concentration from exceeding allowable safety limits in case it leaks. Contact the place of purchase for more information. Excessive refrigerant in a closed ambient environment can lead to oxygen deficiency.

Table.4-3 4.5 Base structures Outdoor unit base structure design should take account of the following considerations: Unit: mm HP 8,10, 12 SIZE A solid base prevents excess vibration and noise. Outdoor unit bases should be constructed on solid ground or on structures of sufficient strength to support the units’ weight. Bases should be at least 200mm high to provide sufficient access for installation of piping. Either steel or concrete bases may be suitable.
If obstacles are around the outdoor unit, they must be 800mm below the top of the outdoor unit. Otherwise, an mechanical exhaust device must be added. 8 ST3.9 self-threading screws A B C D E A A D A C B B B θ Side view Front view (one outdoor unit) (one outdoor unit) A >45° B >300 mm Front view (two outdoor units combined) C Front view (three outdoor units combined) >1000 mm A≥300 B≥250 C≤3000 731≤D≤770 E=A+731 θ≤15° Remove the steel mesh first D Airflow deflector Fig.4-18 Fig.

Outdoor connection pipes g1 isΦ25.4 / Φ12.7, g2 is Φ31.8 / Φ15.9 and g3 is Φ38.1 / Φ19.1. Outdoor connection pipe G1 is Φ41.3 / Φ22.2. There are three outdoor units in the system. Refer to Table 5-7. Outdoor branch joints L and M are FQZHW-03N1E. Table.5-7 Outdoor connection pipes and branch joints selection Outdoor unit Qty.
√ Correct Fig.5-7 Fig.5-11 × Incorrect Fig.5-12 Fig.5-8 5.5 Piping connections between outdoor units 5.6 Piping flushing The piping connecting the outdoor units should be horizontal and must not be higher than the refrigerant outlets. If necessary, to avoid obstacles the piping may be vertically offset below the outlets. When inserting a vertical offset to avoid an obstacle, the whole outdoor piping should be offset, rather than just the section adjacent to the obstacle. Refer to Figure 5-9 to 5-12.
6. Allow time for nitrogen to flow as far as the opening at indoor unit A. 4. If there are no small leakages, charge the piping with nitrogen at 4MPa and leave for at least 24 hours to check for micro leakages. Micro leakages are difficult to detect. To check for micro leakages, allow for any change in ambient temperature over the test period by adjusting the reference pressure by 0.01MPa per 1°C of temperature difference.
5.9 Charging refrigerant CAUTION CAUTION Before performing vacuum drying, make sure that all the outdoor unit stop valves are firmly closed. Only charge refrigerant after performing a gastightness test and vacuum drying. Once the vacuum drying is complete and the vacuum pump is stopped, the low pressure in the piping could suck vacuum pump lubricant into the air conditioning system. The same could happen if the vacuum pump stops unexpectedly during the vacuum drying procedure.
EN/IEC 61000-3-12 = European/International Technical Standard sets the limits for harmonic currents produced by equipment connected to public low-voltage systems with input current > 16A and ≤ 75A per phase. 5.Open the valve where the yellow hose meets the pressure gauge, and open the refrigerant tank slightly to let the refrigerant eliminate the air. Caution: open the tank slowly to avoid freezing your hand.

7.3 Pre-commissioning checks Menu function mode flowchart Before turning on the power to the indoor and outdoor units, ensure the following: 1. All indoor and outdoor refrigeration piping and communication wiring has been connected to the correct refrigeration system and the system to which each indoor and outdoor unit belongs is clearly marked on each unit or recorded in some other suitable place. Start Press “menu” Long press “menu” 5 seconds 2.
The test run procedure is as follows: 1. Open the outdoor unit liquid, gas and oil balance valves. Countermeasure against overhigh thickness: 1. Install a mechanical ventilator to reduce the refrigerant thickness under a critical level. (ventilate regularly) 2. Turn on the power to the outdoor units. 2. Install the leak detector alarm device related to mechanical ventilator if you cannot regularly ventilate. 3. If manual addressing is being used, set the addresses of each indoor unit. b.
