1.2 Indoor unit Features
1.2.1 Cassette
● Innovative design of 6-segment heating exchanger
Instead of old 4-segment type, the new innovative 6-segment heating exchanger enlarges the exchange area. The efficiency of heating exchanging increases 10%-15%. Furthermore, with a large air volume design, the machine can normally work at cooling mode in all the day and night without frost, even in Spring / Autumn.
● Foam-plastic combination technology on the drip tray
It was a long-term and difficult task to prevent the condensing water tray of cassette from fracture and leakage. These problems couldn't be solved perfectly by the old technical craft such as gelatinizing or plastic absorption, and the foam will possibly be broken while it is vibrated or long-term used.
Aux uses an innovative foam-PS combined technology on the water tray and the plastic surface thickness reaches 1mm.
It can make the foam tray firmer and the surface stronger in order to avoid any leakage and fracture.
● Fresh air intake design
A special fresh air intake can lead outdoor fresh air into the indoor for better air quality, which keeps you enjoy the fresh air all the time.
● Higher condensate lift through the inner pump
A condensate pump is mounted inside of the cassette indoor unit. The condensate can be pumped up 750mm from the drip tray.
● Hook design on the panel for the easier installation
Following one of the AUX designing principles, DESIGNING FOR EASIER INSTALLATION, hooks are designed to assist installers to fix the panel on the unit. When installing the panel, just need to hang the four hooks on the unit and then tighten the screws. When maintaining the unit, just need to loosen the screws to take down the panel.
1.2.2 Ceiling & Floor
● Air flow anto control
To realize comfortable temperature in the room, warm air could be sent downwards to every corner of the room.
● Quiet operating
For a comfortable environment, we using line flow fan lowers noise by reducing fan speed, while air input is strong.
● Flexible installation
The indoor unit can be ceiling-mounted on the floor, saving more space. The big room or hall needs high capacity air conditioner.The cabinet type unit not only takes up space, but also doesn’t match with other furnitures. Now you have nothing to worry about.
● Untrathin body design
The unit is very thin, beautiful and elegant, saving space
● Easy to overhang
The indoor unit is light in design, making the whole unit easy to overhang. It has small unit body, easy to install in the common ceiling. thus making up the shortage of push-in type unit.
1.2.3 Duct
● Saving space design
Extrathin design, the whole thickness of indoor unit only 20cm Concealed installation combine indoor decoration perfectly, it almost not make you feel that air conditioner lied.
● Outlet mounted freely
Using duct connection, outlet mounted freely, let the outdoor fresh air easily come into to keep the indoor air pure.
● Flexible and multiplicity
According to the special situation to adopt the differ air reversing and water draining mode to meet the diverse decoration requiement.
● High process condense pump
According to special requirement to choose the 750mm condense pump which avoid the trouble of leakage, meanwhile draining water clearal.
● Long refrigerant pipe
The max. piping length reaches 50 meters.The max fall length reaches 15 meters.
It is more flexible and convenient to mount.

While connection pipe lengthened or larger height difference between indoor and outdoor unit, air conditioner’ s capacity and reliability will reHice. So, the connection of air conditioner pipe should be based on the principle of “shortest route”
2.4.2 Mdify the performance table according to the magnitude of conHiit length and height difference.
The positive side of height difference represents that installation position of outdoor unit is higher than indoors unit, on the contrary, negative side, lower.

3 Design manual
3.1 Selection principle
Please select the air conditioner with relative capacity according to application environment and room area of the air conditioner, and connection pipe length and height difference between indoor and outerdoor unit should be considered.
●Type and application area of air conditioner is listed as following:
Capacity(Btu)
Application area(m 2 ) 12~17 15~25 25~35 35~50 50~70 60~80
Table is not the sole factor; special application environment should be considered while select air conditioner, if not good hermetization or larger load of the room, such as supermarketm store, etc., should select the air conditioner unit with marger capacity.

●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)
●aplication of equivalent length
1) While equivalent length beyond 90 % of maximum actual length (5HP 25meters), the diameter of air pipe should be increased one step. For example: while equivalent length beyond 25 meters, the diameter of air pipe should be 22.2mm from 19.05mm.
2) While didameter of air pipe increasing, the equivalent length should be calculated again. While calculation of performance fall as a result of pipe length based on diagram line, pipe length should be calculated based on effective equivalent length of the pipe.
●Example of effective equivalance calculation: While actual pipe length 5HP 25meters for 5HP outdoor unit is
25 meters, dismeter of ai pipe should be 19.05mm, using 5 elbows and 2 oil traps.
1) equivalent length:25+0.35×5+2.4×2=31.5(m)
27
2) As a result of equivalent length beyond 25 meters, air pipe size of main pipe should be enlarged.
3) effective equivalent length:31.5×0.5=16.7(m)
4) So, while diameter of air pipe of main pipe enlarged, the perfprmance loss as a result of pipe length is equal to the effective length of 16.7 meters.

4.4.3.5 Process
4.4.3.5.1 Check the drainage system before the refrigeration.
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 leak from the Hict and ensure the water flowing successful though the drainage tube finally.
4.4.3.5.2 Suction and exhaust tube installation
Please consult our after 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.
♦ Minimum the length of the Hict
46
♦ Minimum the number of the bends.
4.4.3.5.2 Notice in the installation of the suction and drainage tube
It is suggested that the air Hict with the fog prevention and acoustic absorption can be used (local purchase). The air Hict should be installed before the ceiling hanging and decoration and it should be heat insulated. The special air outlet should be installed at the place with the airflow properly distributed. A checking window should be kept on the suspended ceiling surface for the checking and maintenance in the future.
4.4.3.5.2 Examples for the installations with weakness
♦ Take the hung ceiling inside as the air in Hict, which leads to the humidity rising Hie to the anomalistic air mass outside, the strong wind and the sunshine.
♦ Hie to the water dropping outside the air Hict, the humidity for the new building with concrete will also rise even if the hung ceiling inside is not taken as the air Hict. Thus, the unit should be heat insulated with the glass wool completely. (The glass wool should be bound with the iron gauze.)
♦ The compressor may be overloaded, if it is beyond the unit running limit (e.g. The indoor dry-bulb temperature is 35 , and 24 for the wet -bulb).
♦ With the influence from the capacity of the exhaust fan, the strong wind in the outside air Hict, and the wind direction, the draining water of the heat exchanger will spill if the unit amount of blast is beyond the limit, which will lead to the water leakage.

4.6 Connection piping installation
4.6.1 Choose the Connection piping
4.6.1.1 Three-principle for connection piping
Main reason
Dry
●invasion of outside rain and
constructin water
●invasion of condesating water in pipe
Clean
●oxide form in pipe while welding
●invasioin of Hist, entrained matter
Countermeasurement of prevent failure tubing process→purge→vacuum desiccation
Nitrogen replacement→purge→tubing process
Airtightness
●incomplete welding
●flared pipe air leakage
●fringe leakage
Use proper material (copper pipe, welding rod) operation following strictly welding regulation
→airtightness test
Operation following strictly flared pipe regulation
Operation following strictly interface regulation
4.4.1.2 Close cover of connection pipe
It is important of the binding of the refrigerant tube against the moisture and the Hist inleakage 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.
Area Work cycle Seal method
Outdoor
Over 3 monthes Squeeze to shrunken
Less than 3 monthes Squeeze to shrunken or binding
Indoor Free from it Squeeze to shrunken or binding
① Squeeze to shrunken method : Squeeze the end of steel pipe and weld the gap.
② Binding method : Using PVC stap bind copper pipe ends
Note
1.Avoid the inleakage of the filth as the copper pipe passing the hole.
2.Avoid the inleakage of the rainwater as the copper pipe going to the outdoors.
3.Special attention should be paid while outdoor pipe is in perpendicular status).
4.4.1.3 Connection pipe purge
Pressurization gas purge is a way of removing dirty matters from the pipe.
(Three main functions)
① While “nitrogen replace insufficient”, remove the oxide bubble in copper pipe.
② while pipe enclosure not closed, remove foreigh matters and moisture.
③ check pipe connection of indoor and outdoo r unit (liquid pipe and gas pipe)
50
Example for the operations
① install the pressure adjust valve on nitrogen bottle.
* Used gas must be nitrogen (danger of condesation exists water if using freon or carbon dioxide,and danger of explosive exists if using oxide).
② connect the pressure adjust vavle 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 adju st adjust valve to 5kg/cm 2 .
⑤ check nitrogen whether get across the liquid pipe at the side of A indoor unit
(The interface at the side of indoor unit should be properly enveloped by adhersibe tape in case dirty matters into!)
purge
★Using isolation material in the hand withstand pipe nozzle
↓
★ While cannot withstand Hie to pressure increasing, fast replease isolation material. (First- purge).
↓
★ Using isolation material withstand pipe nozzle(Second- purge).
↓
Check the pipe whether or not by way of putting a rug loosely in pipe nozzle while blow, sometime some moisture will occur, and at that time should desiccate thoroughly the pipe. Method:
(1) Blow the pipe by nitrogen (till moisture not exists any more)
(2) Execute entire vocuum desiccation operation (refer to chapter about tubing desiccation)
⑦ close main nitrogen valve.
⑧ repeat operation above -mentioned for indoor unit B.
⑨ after liquid operation finish, execute blow operation of air pipe above -mentioned again.
4.4.1.4 Selection of connection pipe material
●use long and straight pipe or coil pipe as possible as you can (copper pipe with isolation material) to prevent frequent welding.
●all used pipes must satisfy the requirement listed in table as followed (size, material, thickness, etc.), And material is de-hydrogen-phosphorus-copper seamless pipe.
●if use coil copper pipe with adiabatic material, make the whole work easier.
●don’t use copper pipe used for supply and drainage (Hie to not enough clean of the inner wall)
4.4.1.5 Expanded conncection piping
a) conncection piping must be annealed one time before expansion work.
b) Pipe cutter should be used while cut the pipe (as for large-caliber pipe, use large cutter; if pipe caliber too large to use cutter, use metallic saw, but should be care to prevent sawHist into pipe.) c) Using flaring tool and the dimension of flared pipe section is as shown in following table:
51

Incorrect
● Do not put the liquid tube and the air tube together.
Correct
● Only is the air tube insulated. (cooling only style)
● Both the air tube and liquid line are insulated.
● Support
● The joints of the tubing should be also insulated completely,
Emphasis: ① thickness of heat preservation material should be 100mm.
② The recommendation value (main pi pe 1 inch, brach pipe half inch)should be increased in area with hot and wet environment.
③ if user provides his standard, which should be attached.
④ as for single cold type, if estimate that air conditioner possibly operate while ambient temperature not reach 10 , liquid pipe should execute heat preservation.

8.2.5 Indoor fan operation rule while cooling generation work
A、Operation rule of automatic air velocity
While cooling generation, indoor fan will operate subject to set air velocity; meanwhile, automatic air velocity operation is determined subject to return vent temperature and set temperature. Table 4.4 determines operation rules of automatic air.
Temperature conditin Automatic air velocity
T return air≥T set+3℃
T set+1℃≤T return air < T set+3℃
Output high level air
Output medium level air
T set-1℃<T return air < T set+1℃ Output low level air
After determination of automatic air velocity, judging again need 30 seconds operation at least in case indoor fan air velocity twittering.
B、Air velocity rules under failure protection
While failure protection occurs as shown followed under cooling generation, air velocity changes:
Failure reason
Failure code
Set or automatic high level air
Set or automatic medium level air
Set or automatic low level air
Anti-overload under cold generation
Po04 Low level air Low level air Low level air
After failure recovers to normal conditon, air velocity will recover to set air velocity accordingly.

8.2.6 Air damper motion rule under cooling generation mode
A、Indoor control board drives the increment motor to execute swing of the air damper. Air damper motion has
7 types modes: swing stop, automatic swing, air damper fixing position 1、2、3、4、5.
B、Air damper close
While controller executes shutdown order or just energizes, air damper will close subject to maximum angle so as to ensure complete close of air damper at any angle.
C、Air damper open
While controller executes switch on order, ai damper opens swiftly to pointed position.
D、Air damper automatic swing

8.2.7 Operation rule of water lift pump
To provent indoor unit condesation water spillover and damage of indoor uint or indoor decoration, condesation water should be drained via water lift pump. Operation process of water lift pump is determined by water level status.
After outdoor compressor starts, water lift pump operates under cooling generation or dehunididfucation status.
After compressor stop (or off), water lift pump motor operates for 300 seconds and stops. Under anti-freezing, pump should not stop, after exit anti-freezing, water lift pump will operate subject to mormal condition.
Hiring cooling generation or dehumidification, while water level sensor disconnects (water full) and disconnects continuously 【EC07】seconds, which is judged as water pump system failure, and drainage pump continue to operate, siwching off compressor, and displaying 【Po12】failure on line controller. After that failure is eliminated, unit operates in normal condition again (compressor here-minutes protection in priority).
If failure is not eliminated 30 minutes later, water pump stops and unit enters shutdown status and failure code

Unfreezing is judged subject to temperature difference between indoor coil temperature and return vent tenperature, or treats it subject to timing unfreezing.
8.6 Unfreezing operation
Hiring heat generation, outdoor unit will frost Hie to tool low temperature, which will affect heat generation work. HAC-FX-AUX controller designs many parameters for unfreezing and satisfying unfreezing work process under various conditions. HAC-FX-AUX controller is provided with particular unfreezing work mode, which will be as followed:
8.6.1 Entering condition of unfreezing
Based on the set of unfreezing parameter, several entering modes of unfreezing can be combined. While some prerequisites entering unfreezing operation are satisfied, the unit can enter unfreezing operation.
① Compressor Continuous Operation Hiration
Start to time while compressor starts operation time beyond set parameter value of compressor operation protection time. Meanwhile, if outer pipe temperature ≤【HF01】set value, start to time; if outer pipe temperature>【HF01】set value, clear away the timing.
② Indoor coil temperature condition(no outdoor coil sensor form)
The temperature condition entering unfreezing is determined subject to indoor coil temperature and return vent temperature. Permit entering unfreezing only after satisfying T inner pipe
-T return air
≤【HF02】. If 【HF02】 set is cancel, cancel that judge condition, and unfreezing should operate subject to compressor accumulation operation time.
③ Outdoor coil temperature condition(no outdoor coil sensor form)
The temperature condition entering unfreezing is determined subject to outdoor coil temperature and
【 HF03】parameter. Permit entering unfreezing only after satisfying T inner pipe
≤【HF03】and compressor accumulation time 【HF05】set value and last 5 minutes. If 【HF03】set is cancel, cancel that judge condition, and unfreezing should operate subject to item 4.6.1.2.
Enter unfreezing after both 【HF02】and【HF03】 are canceled, and time condition satisfying 【HF05】.
note: 1、interval between wo unfreezing≥【HF05】
2、while off or controller deenergization, 【HF05】should be cleared.
8.6.2 Exit condition of unfreezing
After unit entering unfreezing, subject to compressor pressure variance, coil temperature variance and unfreezing operation time to judge whether exit unfreezing or not. Exit unfreezing only satisfy one of exit unfreezing.
① Temperature exit condition
While compressor performing unfreezing operaion, outdoor coil temperature raises and satisfies T outer pipe
【 HF04】, that unit exits unfreezing operation.
≥
② Time exit condition
【HF06】set the maximum unit unfreezing operation time, if unfreezing time beyond 【HF06】set time, exit unfreezing operation regardless outdoor coil satisfying 【HF04】set condition.
8.6.3 Unfreezing process
【 SA04】parameter set two unfreezing process function moHiles. While 【SA04】set into ON, compressor will converse to unfreezing opration under non-shutdown condition; While 【SA04】set into OFF, compressor shuts down firstly, and switch on for unfreezing after diversion of four-way dvering valve.
① Non-shutdown unfreezing process
【SA04】set into ON and satisfying entering unfreezing condition, compressor will not stop, and switch off electric heater if electric heater operation included, and then four-way diverting valve diverts and compressor turns into cooling generation operation status. 5 seconds later, outdoor fan switches off and another 5 seconds later indoor fan switches off.
After satisfying exit unfreezing condition, four-way valve is energized and compressor turns into heat generation operation status, and then outdoor fan switches on and indoor fan operates subject to anti-cooling air condition.
83
Hiring unfreezing, not inspect low-pressure pressur switch.
② Shutdown unfreezing process
【SA04】set into OFF and satisfying entering unfreezing condition, and switch off electric heater if electric heater operation included, and then compressor shuts down and 5 seconds outdoor fan stops, and four-way diverting valve deenergizes and diverts, and compressor starts again for unfreezing 30 seconds.
After satisfying exit unfreezing condition, compressor stops firstly, and four-way valve energizes and diverts 30 seconds. If satisfying temperature condition for compressor operation, outdoor fan and compressor start heat generation, and then indoor fan operates subject to anti-cooling air condition.
Hiring unfreezing, not inspect low-pressure pressur switch.
8.7 Timing operation
HAC-FX-AUX controller is provided wit hmany timing operation modes: timing on/off, combination and cycle timing. Timing time is set by way of line controller and remote control.
8.7.1 Timing ON
If set timing ON function, after controller time reaching set timing ON time, execute switch ON order. After timing switches on, the function of timing will cancel. If executes switch operation before not reaching timing
ON time, the function of timing will cancel as well.
8.7.2 Timing OFF
If set timing OFF function, after controller reaching set timing OFF time, execute switch OFF order. After timing switches on, the function of timing will cancel. If executes switch operation before not reaching timing
OFF time, the function of timing will cancel as well.
8.7.3 Combination timing
Combination is a kind of timing mode, which combines timing ON, and timinig OFF. While 【SA09】 is OFF, if select timing ON and timing OFF simultaneously, which means selecting combination timing mode.
Under this mode, after controller executes timing ON and timing OFF operation, timing function will be canceled.
8.7.4 Cycle timing
Cycle timing is also the combination of timing ON and timing OFF, which is not effective only once but 24 which means selecting cycle timing mode.
After set cycle timing, controller can operate in set time period everyday.

10 System failure protection and code
Controller will judge various failures in system operation automatically and treats them accordingly subject to failure types. Failure protection can be classified two types subject to failure reason and treatment method: system recoverable protection and system serious failure protection.
10.1 Controller of HAC-FX-AUX
10.1.1 System recoverable prrotection
While air condition system recoverability occurs, whole system should adopt correlative protection measurement. After failure protected recovers to normal condition, system will recover to nomal condition.
