NOTE: If longer refrigerant pipe is required for the installation, the diameters need to be bigger as shown above with *.

3.1.2 Equivalent length Equivalent length means the conversion length that the pipe pressure loss was considered on the parts of elbow. Etc. Equivalent length: actual pipe length + elbow number × each equivalent length +oil trap number × equivalent length of each oil trap Type Pipe Dia. 9．52 12．70 15．88 19．05 22．02 25．40 28．58 31．80

● While calculation sample of equivalent length: Actual length of 5HP outdoor unit is 25 meters, diameter of air pipe 19.05mm, using 5 elbows and 2 oil traps, the equivalence length is: 25+0.35×5+2.4×2=31.5(m) ● Application of equivalent length 1) While equivalent length is beyond 90 % of maximum actual length (5HP 25meters), the diameter of gas pipe should be increased one level. For example: while equivalent length is beyond 25 meters, the diameter of gas pipe should be changed from 19.05mm into 22.2mm.

2) While diameter of gas pipe increases, the equivalent length should be calculated again. ● Example of effective equivalence calculation: While actual pipe length of 5HP outdoor unit is 25 meters, diameter of gas pipe is 19.05 mm, 5 elbows and 2 oil traps are required.

1) 2) 3) 4)

16

Equivalent length:25+0.35×5+2.4×2=31.5(m) As a result of equivalent length is beyond 25 meters, gas pipe size should be enlarged.

Effective equivalent length:31.5×0.5=16.7(m) So, while diameter of gas pipe is enlarged, the performance because of longer pipe is equal to the effective length of 16.7 meters.

4.2.3 Duct indoor unit installation 4.2.3.1 Select the suspension foundationďźš The suspension foundation must be firm and reliable, and can support the wooden frame and reinforced concrete structure that weigh is more than 200kg. It is necessary to select the structure that is able to resist against certain vibration and keep firmness and supporting capacity in the long run.

4.2.3.2 Fixing of suspension boltďźš Fix the suspension bolts in following methods or install the suspension bolts on iron bracket or wooden bracket.

27

4.2.3.3 The indoor unit hanging 4.2.3.3.1 Adjust the hanger position on the hanging bolt to ensure the unit level in every direction. Keep the unit installed horizontally with the leveling instrument checking after its installation.

4.2.3.3.2 Screw down the nut and ensure the good contact among the hanger, the nut and the gasket.

4.2.3.3.3 Make sure the unit does not sway after its installation.

4.2.3.4 Installation of drainage pipeďźš Heat insulation is necessary for the indoor unit drainage pipe otherwise condensate water will accumulate on the pipe. The pipe root must be well preserved .There should be a gradient/tilting of at least 1% degree without bending.

4.2.3.5 Process 4.2.3.5.1 Check the drainage system before running the unit.

Install a protruding connection fitting on the drainage tube to provide a water inlet before the electrical works finished. Then, check the connection if there is water leaking from the duct and ensure the water flowing successfully going though the drainage tube.

4.2.3.5.2 Suction and exhaust tube installation Please consult our after-sales service staff for the selection and installation of the suction inlet, suction tube, air outlet, and the drainage tube. Calculate the outer static pressure and select the exhaust tube with the proper length and shape.

♌ Minimize the length of the duct. ♌ Minimize the number of the bends.

4.2.3.5.3 Notice in the installation of the suction and drainage tube It is suggested that the air duct with the frost prevention and acoustic absorption can be used (local purchase). The air duct should be installed before the ceiling hanging and decoration and it should be with heat insulation. The special air outlet should be installed where the airflow can be properly distributed. A checking window should be kept on the suspended ceiling surface for the checking and maintenance in the future.

28

4.2.3.5.4 Negative examples for the installations.

♦ Take the space between the ceiling as the air intake duct, which leads to the humidity rising due to the anomalistic air mass outside, the strong wind and the sunshine.

♦ Due to the water dropping outside the air duct, the humidity for the new concrete building will also rise even if the space between ceiling is not taken as the air duct. Thus, the unit should be heat insulated with the glass wool completely. (The glass wool should be bounded with the wire mesh.)

♦ The compressor may be overloaded, if it is beyond the unit running limit (e.g. The indoor dry-ball temperature is 35℃, and 24℃ for the wet-ball).

♦ Because the affection from the capacity of the exhaust fan, the strong wind in the outer air duct, and the wind direction, the draining water of the heat exchanger will spill if the air volume is beyond the limit, which will lead to the water leakage.

●Incomplete welding ●Flared pipe air leakage ●Fringe leakage

Use proper material (copper pipe, welding rod) operation following strictly welding regulation →air tightness test Operate following strictly flared pipe regulation Operate following strictly interface regulation

Seal of connection pipe

It is important of the binding of the connection pipe against the moisture and leakage which is the potential risk in the future.

The end of each tube should be sealed by swathe. In fact, the “extrusion” is the most effective way for sealing, and the “binding” is just a simple replacement in certain conditions.

Extrusion or binding

① Extrusion method：Squeeze the end of steel pipe and weld the gap. ② Binding method：Using PVC strap to bind copper pipe ends

Be careful when 1. The copper pipe going through the hole(The dirt may go into the pipe).

2. Putting the copper pipe outside the room.(The rain water may go into the pipe, Special attention should be paid while outdoor pipe is in vertical position).

34

4.4.1.3 Connection pipe cleaning Compressed air cleaning is a way of removing dirt from the pipe.

(Three main functions) ①

While “nitrogen replace insufficient”, remove the oxide bubble inside copper pipe.

②

While pipe sealing is not good, this can help remove the dirt and moisture.

③

Check pipe connection of indoor and outdoor unit (liquid pipe and gas pipe)

Example for the operations ① Install the pressure adjust valve on nitrogen bottle. * The gas must be nitrogen (condensate may be generated if using freon or carbon dioxide, and the oxygen may cause explosion). ② Connect the pressure adjust valve and inlet at the side of outdoor unit liquid pipe by aeration pipe. ③ Block all copper joints (including B joint) plug except a side of indoor unit by blind plug. ④ Open nitrogen valve and turn adjust valve to the position of 5kg／cm2. ⑤ Check whether the nitrogen go through the liquid pipe to the indoor unit in room A. (The connection port of the indoor unit should be properly covered by the tape belt) ⑥ Cleaning ★ Using isolation material to stop the gas from the pipe ↓ ★ While the pressure is too strong to be held, fast release isolation material. (First clean). ↓ ★ Using isolation material to stop the gas again, then release for the second cleaning. ↓ You can check the moisture by putting a piece of cloth loosely at the outlet of the pipe, if you see any moisture on the cloth, then you should dry the pipe thoroughly.

(1) Blow the pipe by nitrogen (till moisture disappears) (2) Execute entire vacuum drying operation (refer to chapter about tubing drying) ⑦ Close main nitrogen valve.

35

⑧ Repeat operation above-mentioned for indoor unit B. ⑨ After finishing the operation of liquid pipe, execute blow operation of gas pipe above-mentioned again.

4.4.1.4 Selection the material of connection pipe ● Use long and straight pipe or coil pipe as much as you can (copper pipe with isolation material) to avoid frequent welding. ● All pipes must satisfy the requirement listed in table as followed (size, material, thickness, etc.), And material is de-hydrogen-phosphorus-copper seamless pipe. ● It would be easier if you use the copper pipe with insulation. ● Don’t use copper pipe for water supply and drainage (Because it can not be very clean on the inner wall) 4.4.1.5 Expanded pipe connection a) Connection pipe must be annealed one time before expansion work. b) Pipe cutter should be used while cutting the pipe (as for large-caliber pipe, use large cutter; if pipe caliber is too large to use cutter, use metallic saw, but should be care to prevent sawdust from going into pipe.) c) Using expanding tool and the dimension of expanded pipe section is as shown in following table: Piping size

4.4.1.6 Installation of oil trap In order to facilitate oil return, may install oil trap on standpipe.

While height difference between indoor and outdoor unit beyond 8 meters, the distance between oil traps is 10cm as ben conHiit of the following drawing.

4.4.2 Duct insulation 4.4.2.1 Procedure of insulation work condensing pipe work→ insulation (except tubing joint)→ air tightness test →insulation (except pipe joint) 4.4.2.2 Material Insulation material applied should withstand the heat of the pipe.

For example: heat pump; heat resistance transpired polythene (more than 120℃) cooling only type: transpired polythene (more than 100℃) 4.4.2.3 Key points of insulation Insulation area, for example welding area, expansion area or flange area, should be installed after air tightness test finishes. Pay attention to unit model and necessary running condition because some gas pipe and liquid pipe need insulation.

37

Incorrect ● Do not put the liquid pipe and the gas pipe together.

● Only is the gas pipe insulated. (cooling only style)

Correct ● Both the gas pipe and liquid pipe are insulated.

● Support

● The joints of the pipes should be also insulated completely,

Emphasis:

① Thickness of insulation material should be 100mm. ② The recommendation value (main pipe 1 inch, branch pipe half inch)should be increased in area with hot and wet environment. ③ If user provides his specification, it should be attached. ④ As for cooling only type, if you can forecast that air conditioner possibly operate where ambient temperature will be less than 10℃, liquid pipe should apply insulation.

4.4.3.2 Key points of test Strictly carry out the test following the below sequence. a) As various cold medium systems, air pipe and liquid pipe should be pressurized graHially. ● 1st stage 3.0 kg／cm2: Pressurize more than 3 minutes, ● 2nd stage15.0 kg／cm2: Pressurize more than 3 minutes,

→possibly find large leakage →possibly find large leakage

● 3rd stage 28.0 kg／cm2: Pressurize more than 24 hours

NOTE： Even pressurize to 28.0kg／cm2, small leakage cannot be found if time limited.

Thus hold 24 hours and observe after pressurize.

NOTE: Pressure can never be more than 28.0kg／cm2.

38

b) Observe pressure descends or not ● If no descends phenomenon, qualified. ● If descends, should find where the leakage is and refer to next page.

But, if the ambient temperature of pressurization and the ambient temperature of observation is different, there will be 0.1 pressure change for every 1℃, which should be modified. Modified value=( temperature while pressurization—temperature while observation)x0．1.

For example: Pressure 28 kg／cm2,temperature 25℃.24 hours later, if pressure is 27．5 kg／cm2 and temperature is 20℃, which should be taken as qualified.

4.4.3.3 Check air leakage Check 1(as described in last page, find pressure falls in three-stage check) ① Audition check: Find larger air leakage by ears; ② Touch check: Put hand at pipe joint to feel leak or not; ③ Soap water check: Could find bubbles from air leakage.

Check 2 (want to find small leakage, or cannot find leakage while pressure falls under pressurization test) ① Nitrogen to 3．0 kg／cm2 ② Fluorin air (R22) to 5.0 kg／cm2 (i.e. Admixture of nitrogen air and fluorin air) ③ Check by halogen lamp, alkyl gas (petroleum gas) detector, electric detector, etc. ④ If cannot find, continue to pressurize to 28 kg／cm2 and check again.

Maximum pressure not more than 28 kg／cm2

5.3.14 Lift pump operation regulation To prevent indoor unit or furniture being damaged by the condensate overflowed from the indoor unit, a lift pump is required to drain the condensate. The operation status of lift pump is depending on the status of the water level switch.

Only under cooling or dehumidification status, after outdoor compressor started, lift pump motor runs; when compressor is stopped (or powered off), lift pump motor still runs 300s before stop. When anti-freezing, water pump does not stop. After anti-freezing mode quitted, lift pump operates as normal program.

During cooling or dehumidification operation, when the water level sensor switches off (full of water) and keeps 3s, it is judged to be lift pump failure, drainage pump operates continuously, stop compressor, wired controller shows E4 failure code, if the full water failure is cleared, then units restore to normal operation (compressor has 3min protection in priority); if the failure is not cleared within 30min, then water pump stop working and units enter into OFF status, while the wired controller displays E4 failure code.

In case of initial electrifying, lift pump operates for 180s before judging the water level sensor status.

5.3.15 Main controller protection port input 1. The heating overheat protection switch、Water level switch、Remote control output tested by main controller are normally closed contact signal.

Water level switch: When water level is normal, switch is off, if water level goes beyond the normal scope, then Water level switch will switch off to enter into protecting status and alarm output signal.

Heating overheat protection switch: When heating overheat protection switch is off, controller enters into protecting status and alarm output signal.

2. The outdoor protection port tested by main controller adopts strong electricity live wire protection.

When protection switch is off, controller enters into protecting status and alarm output signal.

3. Main controller uses a 4-digit code dial switch to shield every protection port input signal. If some protection port is not used and is tested without stopping operating, this protection can be used.
