- 1 1.1 Notes for installers boxes contain important information which may primarily be of use during field installation, rather than during desk-based system design. 1.2 1.
2 2.1 2.1.1 Placement of outdoor units should take account of the following considerations: Air conditioners should not be exposed to direct radiation from a high-temperature heat source. Air conditioners should not be installed in positions where dust or dirt may affect heat exchangers. nditioners should not be installed in locations where exposure to oil or to corrosive or harmful gases, such as acidic or alkaline gases, may occur.
- 2.1.3 Outdoor unit base structure design should take account of the following considerations: prevents Outdoor unit bases should be constructed on solid ground or on structures weight. Bases should be at least 200mm high to provide sufficient access for installation of piping. - typical concrete specification is 1 part cement, 2 parts sand and 6 parts crushed stone . To ensure that all contact points are equally secure, bases should be completely level.
2.1.5 When units are delivered check whether any damage occurred during shipment. If there is damage to the surface or outside of a unit, submit a written report to the shipping company. Check that the model, specifications and quantity of the units delivered are as ordered. Check that all accessories ordered have been included. Retain the Owner's Manual for future reference. 2.1.6 Do not remove any packaging before hoisting.
2.2 2.2.1 Placement of indoor units should take account of the following considerations: Sufficient space for drain piping and for access during servicing and maintenance should be allowed. To ensure a good cooling/heating effect, short-circuit ventilation (where outlet air returns quickly to a unit s air inlet) should be avoided. To prevent excessive noise or vibration during operation, suspension rods or other weight-bearing fixings should typically be able to bear twice the unit s weight.
3 3.1 Refrigerant piping design should take account of the following considerations: The amount of brazing required should be kept to a minimum. On the two inside sides of the first indoor branch joint ( A in Figures 3-3.4 and - ) the system should, as far as possible, be equal in terms of number of units, total capacities and total piping lengths. 3.2 Only seamless phosphorus-deoxidized copper piping that complies with all applicable legislation should be used.

4 4.1 4.1.1 Pipe flushing should be performed once the brazed connections have been completed with the exception of the final connections to the indoor units. That is, flushing should be performed once the outdoor unit have been connected but before the indoor units are connected. 4.1.2 Vacuum drying4 Pipe manipulation5 techniques Gas tightness test6 1. 2. 3. 4. 5. 6.
4.2 4.2.1 Ensure that piping does not get bent or deformed during delivery or whilst stored. On construction sites store piping in a designated location. To prevent dust or moisture entering, piping should be kept sealed whilst in storage and until it is about to be connected. If piping is to be used soon, seal the openings with plugs or adhesive tape. If piping is to be stored for a long time, charge the piping with nitrogen at 0.2-0.5MPa and seal the openings by brazing.
4.3.3 Insert the expanding head of the pipe expander into the pipe. After completing pipe expansion, rotate the copper pipe a few degrees to rectify the straight line mark left by the expanding head. Ensure that the section of piping is smooth and even. Remove any burrs that remain after cutting. - 4.3.4 Flared joints should be used where a screw thread connection is required. Before flaring 1/2H (half hard) piping, anneal the end of the pipe to be flared.
4.3.5 - - - - 4.4 When the air conditioner is running, the refrigerant piping will deform (shrink, expand, droop). To avoid damage to piping, hangers or supports should be spaced as per the criteria in the Table 3-4.2. In general, the gas and liquid pipes should be suspended in parallel and the interval between support points should be selected according to the diameter of the gas pipe. Table 3-4.
4.5 Warning Never flow oxygen through piping as doing so aids oxidation and could easily lead to explosion and as such is extremely dangerous. Take appropriate safety precautions such as having a fire extinguisher to hand whilst brazing. Flowing nitrogen during brazing Use a pressure reducing valve to flow nitrogen through copper piping at 0.02-0.03MPa during brazing.

4.9.2 During vacuum drying, a vacuum pump is used to lower the pressure in the piping to the extent that any moisture present evaporates. At 5mmHg (755mmHg below typical atmospheric pressure) the boiling point of water is 0°C. Therefore a vacuum pump capable of maintaining a pressure of -756mmHg or lower should be used. Using a vacuum pump with a discharge in excess of 4L/s and a precision level of 0.02mmHg is recommended.
5 5.1 Drain piping design should take account of the following considerations: Indoor unit condensate drain piping needs to be of sufficient diameter to carry the volume of condensate produced at the indoor units and installed at a slope sufficient to allow drainage. Discharge as close as possible to the indoor units is usually preferable.
installed too close to indoor unit lift pumps. - Air conditioner drain piping should be installed separately from waste, rainwater and other drain piping and should not come into direct contact with the ground. Drain piping diameter should ing connection. To allow inspection and maintenance, the piping clamps shipped with units should be used to attach drain piping to indoor units adhesive should not be used. Thermal insulation should be added to drain piping to prevent condensation forming.

Refer to Figure 3-5.7.
5.6 Once installation of a drainage piping system is compete, water tightness and water flow tests should be performed. Water tightness test Fill the piping with water and test for leakages over a 24-hour period. Water flow test (natural drainage test) Slowly fill the drainage pan of each indoor unit with at least 600ml of water through the inspection port and check that the water is discharged through the outlet of the drain piping.
6 6.1 6.1.1 During operation, the temperature of the refrigerant piping varies. Insulation is required to ensure unit performance and compressor lifespan. During cooling, the gas pipe temperature can be very low. Insulation prevents condensation forming on the piping. During heating, the gas pipe temperature can rise to as high as 100°C. Insulation serves as necessary protection from burns. 6.1.
Figure 3-6.1: Installation of joint insulation (unit: mm) 6.2 Use rubber/plastic insulating tube with a B1 fire resistance rating. The insulation should typically be in excess of 10mm thick. For drain piping installed inside a wall, insulation is not required. Use suitable adhesive to seal seams and joints in the insulation and then bind with cloth reinforced tape of width not less than 50mm. Ensure tape is fixed firmly to avoid condensation.
7 7.1 - - 6.35 9.53 12.7 15.9 7.2 Only charge refrigerant after performing a gas tightness test and vacuum drying. Never charge more refrigerant than required as doing so can lead to liquid hammering. Only use refrigerant R410A - charging with an unsuitable substance may cause explosions or accidents. Use tools and equipment designed for use with R410A to ensure required pressure resistance and to prevent foreign materials from entering the system.
