3.3顶装

按照开孔图开孔, 再锁紧制冷机底部内置的螺丝孔保证制冷机与控制柜的固定与密封。

4．安全与注意

安全提示

?制冷机为精密电气，搬运务必轻放，严禁倒置，倾斜存放。

?安装制冷机前，应该先取开外壳，（松开制冷机顶部的螺丝，由下向上垂直推卸外壳），把制冷机安装上控制柜后再把外壳装上制冷机（靠紧制冷机四周边框，由上向下卡入钩环，再拧紧制冷机顶部的两粒螺钉）

?因制冷机为无冷凝水设计，制冷机的出水管只为安全备份使用，正常使用时无水导出，不必考虑冷凝水的处理。

注意事项

?制冷机在灰尘大，或油性，毛绒的环境务必及时清理过滤网，否则会影响制冷机性能。

?制冷机入风口需安装到控制柜体的上部。

?控制柜外的温度不能超过55摄氏度，但短暂的高温并不影响制冷机运作。

?包装应完好，如果发现制冷机有油渍，极有可能是泄漏制冷剂，包装的任何损坏都有可能引起制冷机的故障。

?控制柜必须达到IP54，如果控制柜有漏洞或缝隙，冷凝水可能会发生。

?制冷机之间或制冷机与墙壁距离至少不小于200mm

?在控制柜内部，制冷机入风和出风口不可有障碍物阻塞。

?制冷机需水平安装、使用，最大倾斜角度不大于2°

?维护及送电必须由专业人员操作。

?为避免冷凝物的形成，建议采用门位开关，保证当控制柜门打开时，制冷机必须关闭。

?控制柜内部的电气元件的热释放不能超过制冷机可用制冷功率，否则会出现制冷机长期运作。

?不可用任何方式修改制冷机。

5．电气联接

电压与频率必须与制冷机的铭牌相匹配，在制冷机电气联接前端不可有其他的温度控制，制冷机上回路电保护元件应与制冷机额定功率相吻合，在安装时参考相关说明。

三相制冷机建议采用马达保护器。

特殊电压请参照相关手册安装使用。

6．常规操作

在联接电源后，打开总开关，蒸发风机会一直运转，保证控制柜内部的空气流动，避免热积累。制冷机温控器出厂已经设定为35度，（建议使用出厂设定），制冷机根据设定温度自动开闭制冷压缩机运作。

当制冷机有故障时，信号12，13点提供开关量的输出，制冷机停止工作，维修完毕后手动复位热继电器开始工作，（出厂设定热继电器为自动复位），此一功能为可选功能。

制冷机过滤网有金属过滤网及PU 高分子过滤网两种（标准供货为金属过滤网）

由于外循环风机足够的风量和风压，细微尘粒被直接吹过，不影响制冷机运作。

金属过滤网用于抵御大颗粒灰尘，及油污和毛绒性环境，

7．工作原理

制冷机采用相变制冷原理，从压缩机内排出的高温高压气态制冷剂进入冷凝器，被强制冷却为高压中温的液态制冷剂，经毛细管或膨胀阀节流后变成低温低压的液态制冷剂，进入到蒸发器，通过相变吸收控制柜内的热量后变成气态再进入压缩机，往复循环保证控制柜的可靠工作环境。

According to production model, the unit can be vertical-mounted, top-mounted, horizontal-mounted, there into vertical-mounted, top-mounted units also can be external installed, or partially installed to chioce. Cut out the sections and drill according to mounting diagram as below.

3.1 partially installed

Simple square sections cutting. Cut the enclosed deals to the required length according to the mounting diagram and attach to the unit with enclosure pitched by two stopper blocks. Screw the bolt into the blind nuts around the unit. The unit is then to be secured fastness and airproof.

3.2 external installed

First of all, an additional frame matched with the relevant units should install on the unit to fill in the area concave between unit with enclosure. Cut the enclosed seals to the required length and attach to the unit in accordance with mounting diagram, Screw the bolt into the blind nuts on the rear of the unit.

3.3 top-mounted

Cut the enclosed deals to the required length according to the mounting diagram, Screw the bolt into the blind nuts on the bottom of the unit.

4. Safety and Attentions

Safety Notices

The following safety notices are to be observed in their entirety for the correct use of equipment.

?To prevent the enclosure with the climate control unit fitted tipping over. It is essential that this be bolted to the floor.

?The outing shell should be uninstalled previously (loosen the two bolts on the top of the unit, shift off the outing shell upright and upwards), fit the shell on the main unit before attaching the main unit into the enclosure according to instructions ( lean and hook on to the main unit and drive the outing shell to integration basipetally, screw the bolts just like before)

?Thanks to the condensate drainage free design of the units, the water pipe is backup for the safety, do not take into account the condensate drainage allocation.

Attention Notices

?The location is free from excessive dirt and moisture, greasy environment. The filter net should be cleaned in time otherwise the performance of the unite will be lower.

?The cutout for air extraction is located in the upper area of the enclosure.

?The ambient temperature does not exceed +55°C, but the temporary high temperature is acceptable.

?The packaging shows no signs of damage. Traces of oil on damaged packaging are an indication of refrigerant loss and of leakage in the unit system. Any damage to the packaging may be the cause of subsequent malfunctions;

?the enclosure is sealed on all sides (IP 54). Condensation will occur if the enclosure is leaky.

?The separation of the units from one another and from the wall should not be less than 200 mm.

?Air inlet and outlet are not obstructed on the inside of the enclosure.

?Units are only fitted horizontally in the specified position. Max. deviation from the true horizontal: 2°.

?Electrical connection and repair are carried out only by authorized person. Use only original replacement parts!

?To avoid an increase in condensation, a door operated switch should be used which will switch the cooling unit off when the enclosure door is opened.

?losses from the components installed in the enclosure must not exceed the specific refrigeration capacity of the cooling unit itself, otherwise the units will working all the time.

?the customer must not modify the cooling unit in any way.

5. Electrical Connection

The connected voltage and frequency must correspond to the values stated on the rating plate. During commissioning, the data on the rating plate of the device shall apply. The unit must not have any additional temperature control connected up-stream at the supply end. Line protection should be provided by means of the pre-fuse specified on the rating plate. Observe the relevant regulations during installation!

The three phase supplies are to be connected via a motor safety switch to a TN grid with grounded star point.

Specially rated units, which are also fitted with a transformer, standard motor safety switches no longer suffice due to their switching characteristics. Therefore transformer safety switches must be installed on the customer side. These are to be set to the rated current given on the nameplate.

For units designed for three phase 400/460 V, the rotary field or the absence of a phase must be monitored. If the rotary field is incorrect or a phase is absent, the unit will not run.

6. Routine operation

After electrical connection, switch on the main breaker of the unit, the evaporator fan will run continuously to circulate the air inside the enclosure. The installed basic controller (setting the desired internal temperature, factory setting +35°C ) provides automatic control switch-off of the cooling unit by the set value of the fixed switching difference of 5 K..

Fault signal relay with changeover contact Terminal 12 and Terminal 13 NC (normally closed), this is function is Supplementary functions. As a result, the relay contacts change their state representing the normal operating status of the cooling unit. As soon as a system message occurs or the voltage supply is interrupted, the relay drops out. (see also circuit diagrams ).

The PU foam filter mat available as an accessory is coarse and filters large dust particles or fluff from the air. Metallic filter mats are used to trap oil condensate. These are also available as an accessory. Subject to the suction of the blower being high enough, fine dust is blown through the filter mat and the external circuit of the unit. This does not affect the unit's operation..

7. Working Theory

The compressor takes the gaseous refrigerant from the evaporator and compresses it to a higher pressure in the condenser. During this process the temperature of the refrigerant rises above the ambient temperature and heat can be dissipated to the environment via the surface of the condenser. Then the refrigerant is liquefied and by means of a thermostatically controlled expansion valve, returned to the evaporator, where it evaporates at low pressure. The heat required for complete evaporation is drawn from the enclosure interior causing it to cool down. The cooling cycle is thus completed, the aforementioned process of the heat transfer starts afresh.

8. Maintenance

As a maintenance-free, hermetically sealed system, the cooling circuit has been filled in the factory with the required amount of refrigerant, and tested for leaks and subjected to a function trial run. The installed maintenance-free fans use ball bearings; they are protected against moisture and dust, and are fitted with a temperature monitor. The life expectancy is at least 30,000 operating hours. The cooling unit is thus largely maintenance free. All that may be required from time to time is that the components of the external air circuit are cleaned by compressed air.

The use of a filter mat is recommended only if large particles of lint are present in the air, so that blockage of the condenser is prevented.

Prior to any maintenance work, the power to the cooling unit must be disconnected.

9. Quality Guarantee

This unit is covered by a 1-year guarantee from the date of supply, subject to correct usage (See also Safety notices ).Within this period, the returned unit will be repaired in the factory or replaced free of charge.

The cooling unit is to be used for the cooling of enclosures only. If it is connected or handled improperly the manufacturer’s guarantee does not apply and in this case we are not liable for any damage caused.
