3. Installation
3.1 Install into system
Note! This series is only for install indoors or in
a ventilated cabinet. Do not install outdoors directly.
If you need to install outdoors, please use ICUN series.
Model number CDT048~CDT125 can be selected
with optional plastic base plate, this base plate is designed
for installing compressor. Please use the bolts come
with product to fix compressor onto plastic base plate.
The condenser with base plate could be fastened onto your
system structure via 4mm or 3/16” self-tapping screws or
bolts.
For condensers without base plate, use 4mm or 3/16”
self-tapping screws or bolts to fix condenser via anchor
holes on each side of endplates. Each side is with 3
anchor holes. Be careful, do not damage headers or tube
bends while fixing condenser.
Before shipping, CDT300~CDT1000 have been
pressurized inside to block moisture. While releasing
gas via cutting connection tube before connection, do
watch out the gas blowout. After releasing pressure, do
piping as soon as possible to avoid moisture and dusts
invading.
CDT048~CDT250 have been purged by dry gas and
sealed with rubber caps. When caps are removed, please
do piping as soon as possible.
All the packing materials disposal must meet local
regulation.

3.2 Positioning condenser
In order to get the best performance of your
condenser, you must install the condenser in a correct
place. The following general rules must be followed
while selecting the position for condenser:
1. This series condenser must be installed indoors and
there must be no obstacle on both inlet and outlet air
side. This condenser is NOT designed for installing
air duct and NOT for outdoor application.
2. In order to get better air flow, please do consider air
tunnel in your system. Especially installed in a
cabinet. .
3. When install multi-condensers system, do avoid the
air flow interference between condensers. Must
avoid one’s discharged flow becomes another one’s
inlet air. Air inlet side must be kept at least 150mm
away from wall.
4. Please avoid the corrosive environment, if it has to be,
order anti-corrosion type and clean the condenser
more often.
Before installation, check the position and reserve
maintenance space.
3.2 冷凝器的安裝位置
為了確保冷凝器能發揮最大的效能，必須要將冷
凝器裝置在正確的位置。在選擇安裝位置時，必須要
遵守以下的通則：
1. 本系列冷凝器必須要安裝於室內，且進排風側必
須要無障礙物。本系列冷凝器
並非
為安裝風管所
設計且
非
設計於室外安裝。
2. 為獲得較佳的氣流，請考慮安裝於系統中之氣流
通道，特別是安裝於箱體中的情形時。
3. 在使用多組冷凝器系統時，要注意避免冷凝器之
間的氣流互相干擾，避免一個冷凝器的排風成為
另一個冷凝器的入風，如果必須要入風側對入風
側的安裝，兩個冷凝器間的距離至少要為一個葉
徑的距離。入風側與牆的距離至少要為 150mm的
距離。
4. 請儘可能避開安裝於腐蝕性的環境，如果必須如
此，請選購防蝕型機種並經常清洗冷凝器。
在安裝前務必確認位置，並預留維護空間。
Caution
！ 注意！
Sharp edge hazard!
小心銳利邊緣危害！
Must avoid one’s discharged flow becomes another one’s inlet air.
避免一個冷凝器的排風成為另一個冷凝器的入風。

Caution
！
Piping working must be executed
by professional technician!
3.3 Refrigerant Piping
* Refrigerant piping must be done by professional
technician and follow the national codes.
* Please follow ASHRAE guide line for refrigerant
piping.
* The liquid line should not be suddenly expanded in
refrigerant direction to avoid flash happening.
* Refrigerant line should be as short as possible to
reduce pressure drop.
a. In order to prevent moisture entering condenser, the
condenser is sealed with pressurized dry gas. Before
brazing the tube, cut the inlet or outlet tube for
exhausting sealed gas. Be careful for the ejected gas.
Take personal safety protecting equipment while
working.
b. When the condenser reaches to the zero pressure status,
deburr the tube ends and expand the tube for brazing.
For the good cleanness inside the system, use dry
nitrogen to purge the oxygen out. This will prevent
forming oxide inside during brazing.
c. When finish connecting all the components, perform
leak teat and vacuuming. Make sure there is no leak
and reach the vacuum level required. It’s important
for steady system operating.
3.4 Wiring
Wiring work must be
executed by professional
technician
and follow the
related electric codes!
a. Use the correct tool for wiring.
b. Please select the correct electrical wire based on the
rating current specified on the connection diagram.
(Connection diagram is on the back of terminal box
cover.)
c. Connect the fan motor to power source, check if the
rotation direction is correct.
d. For safety reason, be sure to ground condenser.
BE SURE TO GROUND
CONDENSER!
注意！
配管作業必須由專業人員執行！
3.3 冷媒配管
※配管必須符合國家相關法規與系統實際操作需求。
並由專業技術人員執行。
※請依照 ASHRAE 手冊的冷媒配管指導原則進行配
管。
※配液管時在冷媒的行進方向不可以有突然管徑變大
的情形，以免發生閃變。
※冷媒管路盡可能保持短，以降低管路壓損。
a. 為確保冷凝器管路內部保持乾燥，出廠前內部會充
填乾燥氣體。焊接前，請小心切開出入管，讓冷凝
器內部氣體排出。注意!釋氣時應注意噴出氣體，工
作時請穿戴個人安全防護裝備。
b. 當冷凝器達到零壓力後，開始進行銅管切口去毛邊
與擴口準備焊接。為維持管內的潔淨，焊接前請先
以氮氣掃除原管內的氧氣，焊接時請以微量氮氣充
入管內進行焊接，以避免管內氧化！
c. 當連接完成所有的管路後，進行測漏與抽真空。確
認系統無洩漏且達到所需要的真空度。此對於日後
系統穩定運轉是十分重要。
3.4電路接線
電路接線工作必須由專業
技術人員並依照國家電工
相關法規執行！
a. 請使用正確的工具進行接線。
b. 請依照接線圖上所標示的額定運轉電流選擇適當
的電線規格。(接線圖位於端子盒蓋背面。)
c. 將馬達與電源接妥，並測試馬達轉向是否正確。
d. 為了安全起見，務必將冷凝器接地。
務必將冷凝器接地！

4. Test running and adjustment
4.1 Before start up
Before setting system into working, the following
check list must be examined very carefully:
Check fan support(s) is/are fastened firmly. All the
screws are fixed. There is no loose part before
running.
Check the level of condenser is correct.
Check all the electric wirings are correctly connected
and fastened tightly.
Check the power source is correct. And the fan is in
right rotation direction.
Check the refrigerant piping is connected and all
valves are in their positions. System is filled up
suitable refrigerant quantity.
4.2 Check and adjust while running
In order to keep system in steady running, must adjust
well in test running, the following check list must be
examined and adjusted with patience.
* Check for fans rotating direction, make sure all the
fans run in correction direction. Check the current if
it is correct.
* Check if there is any short circuit in air side.
* Check oil level, if too low add adequate oil to standard
oil level. If system is equipped with high pressure
side oil separator, there is no oil return at high
temperature but oil returns at low temperature. Do
check the capacity of oil separator if it is too small.
* Check if condensing temperature is at the design point.
Be sure to consider the outdoor air temperature while
checking condensing temperature.
* Check sight glass of liquid line. The liquid must be
full at the rating operation.
Caution
！
Keep hands away from fan
blades! Fan might operate
unpredictable!
4. 試車與調整
4.1 啟動前檢查
在啟動系統之前，請仔細確認以下相關事項：
確認風車支架是否被牢固鎖定，所有的螺絲已被
旋緊。運轉前確認無其他鬆動零件。
檢查冷凝器的水平是否正確。.
檢查所有電線是否正確連接且已鎖緊。
檢查供電電源是否正常，確認風扇轉向正確。
確認冷媒管路已連接妥當，所有的閥都在正確的
位置。系統已充填適當的冷媒量。
4.2 運轉時的檢查與調整
為確保系統能穩定運轉，試車時必須要仔細調校，
以下的檢查項目在試車過程中必須要耐心觀察與調
整。
*檢查風扇運轉方向，確保所有的風扇向正確。檢查運
轉電流。
*檢查空氣是否有短循環。
*檢查油位，如果油位過低加入適量的冷凍油至標準
油位。如果系統裝有高壓側油分離器，在高溫段不回
油低溫段才回油的情形，請檢查油分離器的能力是
否過小。
*檢查冷凝溫度是否在設計點。檢查冷凝溫度時請同
時考慮當時的外氣溫度。
*檢查液管的視窗，在額定運轉時視窗必須呈現滿溢
情形。
注意！
將手遠離扇葉避免受傷! 風扇
可能無預期運轉！

5. Maintenance
In order to keep condenser in a good condition, you
have to check the condenser periodically. The following
items must be done for check.
a. Clean the fins periodically for retaining performance.
Use clean water to wash fins. Water pressure must
be lower than 4 bars. Be careful not to damage the
fins, otherwise it will block air flow. Use fin comb
to straighten the damaged fin. If needed, use neutral
detergent to clean the coil. Must rinse the coil till
no residence left.
**If condenser is coated with EnergyGuard, please
follow instruction of EnergyGuard!**
b. Clean fan blades and air streamer fan guard. If fan
blades are damaged or bent, replace with new ones.
c. Check every electrical connection is fastened. Also
check if there is any current leakage, find out the
problem and fix it.
d. Check fan motor if there is any noise. If so, fix it or
replace it.
e. Check every screw and bolt, if there is any loose part,
fasten it.
f. Check tubes and brazed parts of condenser if there is
any stain or spot. If there is any corrosion happened,
do remove the aggressive material(s), and check if
there is any leak.
Caution
！
Be sure to disconnect the power
line before any maintenance or
repairing!
5. 保養
為確保冷凝器維持良好的運轉狀態，請定期檢查
並保養冷凝器。
a. 定期清潔鰭片確保熱傳效能的維持。使用清水清
潔鰭片，水的壓力必須要低於 4 bar。清潔時要注
意不可以損壞鳍片，以免阻擋氣流通道。使用鰭
片梳將傾倒的鰭片梳直。必要時使用中性清潔劑
清洗盤管，清洗後務必潤洗乾淨至無殘留物留在
熱交換器上。
＊＊如果冷凝器已進行衛能防蝕處理，請依照衛能
保養說明進行清潔！＊＊
b. 清潔扇葉與導風罩。如果扇葉受損或彎曲請更換
新的扇葉。
c. 檢查電氣接點是否鬆脫，鎖緊鬆脫的部分。同時
檢查是否有漏電的情形，如有請找出原因並予以
修復。
d. 檢查風扇馬達是否有異音，如有請修復或是更換
馬達。
e. 檢查所有的螺絲與螺栓，如果有鬆脫的部分請鎖
緊。
f. 檢查冷凝器的管路與焊接點是否有銹點與污斑。
如果發生鏽蝕情形，請將腐蝕性物質移離，並檢
查系統是否洩漏。
注意！
在從事任何保養維修前，請注意將
冷凝器斷電以免受傷！
