Installation guide 2. Product handling Problem analysis Dropping the product, due to rough or careless handling of the product during unloading process. Consequence It will cause the product damage/deformation and may also cause motor fixation kit to fall off. Such consequences will interrupt normal operation of the product and lead to noise generation. Furthermore, severe damages to the electrical parts may cause performance decrease and even serious accident which may involve personal injury.
2. Preparation for installation Problem analysis A chassis of outdoor unit is bent and a heat exchanger of the condenser is damaged due to inappropriate transportation method. Consequence When moving the product, you must lift up and down the product gently. When the product is scratched, product will corrode or get rust. If the heat exchanger of the condenser gets damaged, it will cause deteriorating performance and even make a leakage from the pipe.
Installation guide Problem analysis Product is left alone in the open site. If the ground gets wet with water after rain or due to other reasons, it will cause bad effect on the product. Consequence If the indoor unit products gets soaked, water will damage the packaging first and then it may get into the indoor unit and damage the electrical parts. Such damage may cause critical safety trouble. Standard procedure When leaving the product in the site, you must store them properly.
2. Preparation for installation Problem analysis Pile of indoor units in the site is too high and some of the products are even piled up vertically. Consequence Pile may fall down and cause personal injury. Indoor units lying on the bottom of the pile may get damaged due to pressure. Standard procedure Pile cannot be over 6rows and exceed 2m(6.5ft) in height. You cannot pile them vertically either. Proper method 1. Do not pile the indoor units too high.
Installation guide Problem analysis Indoor units are stored vertically. Not only that, it is left on the ground and the ground is wet with large amount of water. Consequence Pile may fall down and cause personal injury. Indoor units lying on the bottom of the pile may get damaged due to pressure. If the indoor units get soaked, water will damage the packaging first and then it may get into the indoor unit and damage the electrical parts Standard procedure Store the indoor units horizontally.
2. Preparation for installation Problem analysis Products are stored messily in the site and there is no manager in charge. Consequence Products are bumped into each other and pressed by one another which cause structural deformation. Internal parts of the product may get damaged or even lost. Standard procedure When storing the indoor unit : 1. Do not mix different models. 2. Do not leave them upside down. 3. Do not leave them vertically. 4. Do not tilt the indoor units. 5.
Installation guide Problem analysis Inappropriate product management caused outer packaging damage. Consequence After damage to the outer packaging of indoor unit, dust and other foreign substances entered to the product. Furthermore, you may lose , , drainpipe or other parts needed for installation. Standard procedure Strictly regulate the package removal before installing the indoor units. Manage and keep all the related parts and manuals thoroughly.
2. Preparation for installation Problem analysis Indoor unit installation is put on hold, and it was left with all the packaging removed. Dust, foreign substances, rain water, industrial water and dew got inside of the indoor unit. Because it was left with all the packaging removed while installation was put on hold. Consequence Dust and other foreign substances will get inside and cause pipe blockage or other malfunctions.
Installation guide Problem analysis Indoor unit, which is still in the middle of the installation process, is hanging on the ceiling without any protection. Consequence Indoor unit was hanging on the ceiling without any Protection which allows dust and other foreign substances to enter and cause malfunction.
2. Preparation for installation Problem analysis Safety net is not installed on 4-way cassette indoor unit. Consequence Safety of client and service agent can be at risk. Standard procedure Install the safety net for safety reasons. Proper method Make sure safety net is installed and let the customer know that they must not remove them for their own safety.
Installation guide 3. Materials and Tools Problem analysis R410a refrigerant system has relatively high pressure. If material does not meet the pressure-proof standards, then it may cause copper pipe explosion. Consequence Intensity and material specification doesn’t meet factory requirement and this could lead to explosion while using the product which could even bring personal injury.
2. Preparation for installation Problem analysis Layer of carbon, rust and dirty foreign substances were found on the outer surface of the copper pipe. Pipes must not have any scratches, indents or stains etc. Consequence Such defects decrease the strength of the pipe which may result in explosion, decrease in performance or leakage. Standard procedure You must select clean and dry copper pipe. Check inside of the pipe for any dust, water, indents or any signs of damage.
Installation guide Problem analysis Due to inappropriate protection management of the internal/external surface of the copper, large amount of oxidation, dust and foreign substances were seen. Consequence R410a refrigerant is very sensitively react with foreign substances : Mineral oil and compress oil will not solve with each other due to different chemical characteristics. Therefore, wax type materials may clog the hole of EEV or oil filters. Standard procedure Check if it is clean enough.
2. Preparation for installation Problem analysis After purchasing the pipe, it was not kept properly so dust, foreign substances, water and industrial water got inside of the pipe. Also pipe was left on the ground and people just walked on them. Consequence Water or foreign substances within the pipe will cause blockage that can lead to product malfunction or performance decrease.
Installation guide Problem analysis Thickness of the pipe does not meet the standards. Consequence Strength and the duration of the pipe will decrease which may cause breakup. Especially, R410a is a high pressure gas. Pipe with less thickness will have less strength, which may cause the pipe breakup. Standard procedure Required thickness – Soft type Outer diameter(mm) Min. Thickness(mm) Ø6.35 0.8 Ø9.52 0.8 Ø12.70 0.8 Ø15.88 1.0 Required thickness – Semi hard type Outer diameter(mm) Min.
2. Preparation for installation Problem analysis Selecting ø22.23 copper pipe, and 10mm insulation as shown in the picture. Consequence Low insulation effect cause large energy consumption and decrease in system performance. Condensation will easily form and leakage may occur when performing heating operation in regions with high temperature and humidity. Standard procedure Insulation material and quality must meet the minimum standard thickness requirements.
Installation guide Problem analysis Regular vacuum pump was used in vacuum operation. Consequence If the power of the vacuum pump cuts off unexpectedly then the oil gets back to the refrigerant system due to pressure difference. Standard procedure Use the vacuum pump which is 100% dedicated for R410a system with stop valve. Proper method Purchase and use the vacuum pump with the stop valve.
2. Preparation for installation Problem analysis R22 gauge was used in R410a system. Consequence If you use R22 gauge, remaining oil inside can generate wax type material which definitely badly affect POE oil of R410a system, possibly clogging refrigerant passage or causing compressor failure. Standard procedure Never utilize R22 gauge for R410a system to prevent the mineral oil from flowing in to the R410a system. Use the measuring instruments that meets the standard requirement.
3. Guideline for each installation process Installation guide 1. Sleeve work 1-1. Positioning of the pipe holes 1) The through holes for the drain piping should be positioned such that the pipes have a downward gradient. (The gradient must be at least 1/100.
