Installation Note

1.Read the instructions thoroughly.Failure to complywill causevalve failure,systemdamage, orpersonal injury.

2.When soldering or brazing,direct the flame away from the body,and wet rags must be used to prevent damaging the moisture indicator.

3.The sight glassmaybe installedanywhere in the liquid line and inany position.It is normally installed downstream fromthe filter-drier, wherethe sight glass indicationmeans:

Green:Therefrigerantdoes not have dangerous moisture;

Yellow:Therefrigerantahead of the expansion valvehas too high Moisture content.

Bubbles:

1) Pressure drop across the filter drier too high.
2) No sub-cooling.
3)Refrigerantinsufficientinthewholesystem.

4.Ifthesightglassinstalledahead of thefilter drier,the indicationmeans:

Green:The refrigerant does not have dangerous moisture;
Yellow:Moisture content too high in the whole refrigerationsystem.

Bubbles:

1) No sub-cooling.
2)Refrigerant insufficient in the whole system.

Note:If the bubbles occur in the sight glasses,do not replenish refrigerant,firstto find out the cause ofthebubbles!

5.If need to indicate both total moisture content inthesystemandrefrigerantconditionahead of expansion valve,thena sight glass must be installed to both sides of the filter drier.

Note:The moisture indicator may belightyellow on installation because ofitsabsorbance of ambient air.When installittorefrigerationsystem,theindicatorchangestogreenonconditionthatrefrigerant moisturewithinthepermissiblerange,andthisbalance timeisaround10 hours.Iftheindicatordoes notchange to green more than 10 hours,the user need tofindthe root cause ormay need to change filterdrier.

Thevibration absorbersare designed to installoncommercialrefrigerating systemsand on civil and industrialair conditioning systems,and can be installed both on suction and discharge lines.

Its function is to avoid the transmission of compressor's vibrations to therefrigerating system pipes, reducingtheriskof damageandnoise level.

The vibration absorbersare constructed ofa deep pitch corrugated hose covered with a stainless steelbraid.The hoseand braid are reinforcedbyferrulesat each end and connected to copper tube endsbyahightemperaturebrazealloy.

PKR避震管是由深度褶皱的不锈钢制作而成，用以增加管子的灵活度和吸收震动的效果，外部是不锈钢网编织层，编织层有助于增加耐压等级。波纹管与外部的不锈钢网套在两端处加固，连接到内螺纹的紫铜管由高温黄铜焊接而成。

Main Features

Installation Note

1.The vibration absorber should be installed as close as possible to the compressorand must be installed inastraight line. Note:vibration absorbers are not designed to compensate for pipe work misalignment.
2.Note:Leave sufficient space for the vibration absorber to avoid static compression ortension when welding itto the pipes.Vibration absorbers are not designed to absorb axial torsional stress.
3.Fit thevibrationabsorbers perpendicular to thevibration direction. Two vibration absorbers should be used when vibration exists in two planes.
4.Inordertogetoptimum vibration absorption,therefrigerantlineshould beanchoredatthe end of the vibration absorber furthest from the vibration source.
5.Vibration absorbers should be fited horizontally when used in suction lines or where working temperaturesare below freezing point. If installed vertically,condensation may formon the outside of the unitand the absorption effect will be reduced.Insubsequent freezing maydeformand destroy theunit. If vertical installation is theonlyoption,orcondensation is possible indeed with horizontal mounting, therefore the entire flexible section,ferrules and braided hose,must be coveredwith awatertight synthetic materiale.g.a heatshrinkable PVC sleeve.
6.When installing the vibrationabsorber,the ferrule and startof braid must be wet-ragged forbrazing

to prevent overheatingand subsequent damage.

Applications

PK distributorsare designed to distribute liquid refrigerants fromthe thermostatic expansionvalve toindividualevaporatorsectionsuniformly.

Fails to distribute uniformly willmake some shunt refrigerant too much,thus the evaporator will be frostingand evaporate incomplete;ormake shuntrefrigeranttoo less,thus theevaporator's heat transferareacan'tbefullyutilized.

The general performance is therefrigeration capacity decreased,the liquid may accompanied by suction,which willseriously impactthe performance and reliability of the refrigeration system.

Application

Themuffler is installed to the discharge line of thecompressor;its function istoreduce pressure pulsations downstreamof the Compressor.

Mufflers have internal baffles which are designed to dampen and gentle low and high frequency compressorgassoundwaves.Anditreduces noise due to gas pulsations,byallowing the gas toexpandinsidemufflerchambers.

Itisa good choice for high noisyunit.

消音器的作用在于排除压缩机在运转时所产生的压缩振动和噪音，直接安装到压缩机后面。内部设有几道隔板，以降低压缩机运转时所产生的谐振噪音频率。消音器对于噪音较高的机种是很好的选择。选择消音器的时候选择等于或大于排气管路的接口，大型消音器因为较大的内部容积，易于消除更多的振动。

4.兼容HFCs和HCFCs制冷剂及对应的油
5.消音器只能消除排气脉动产生的噪音，如是振动产生的噪音，则应加装避震管到排气管路或者吸气管路；
6.单个消音器可以安装在普通排气管道，也可以为并联机组的每一个压缩机配备一个消音器。

Recommend to select mufflerwitha connection size that matches or exceeds thedischarge line size.
Largermufflercan remove more pulsations due to the larger internalvolume.
1、消音器安装到尽可能靠近压缩机的位置，并在油分离器之前；在压缩机和消音器之间安装一个避震管以防止传输振动；
2、水平或者倾斜安装时，贴标一侧必须位于顶部中心位置，以防止油沉积在消音器内。消声器内有油会降低消音器性能，同时导致压缩机曲轴箱中的油流失。安装消声器的时候稍稍倾斜，使出口比进口低，也有助于防止油沉积。垂直安装的消声器不会存储油；
3、消音器只能消除排气脉动产生的噪音，如是振动产生的噪音，则应加装避震管到排气管路或者吸气管路；
4、单个消音器可以安装在普通排气管道，也可以为并联机组的每一个压缩机配备一个消音器。

Installation Notes

1.The Muffler should be installedas close as possible to the compressorand before the oil separator.

2.·The muffler fittedin a horizontalorangled position,the side with label must be top centerto help prevent oil collection inside the Muffler.The oil inside the mufflerwillreduce the performance andcauseoilloss inthecompressorcrankcase. ·The mufler fixed ata slightangle makes the outlet port below the inlet also helps prevent oil collection. * Mufflers that fitted vertically will not collect oil.
3.A Vibration absorber should be installed between the compressor and muffler to prevent transmitted vibration.
4.Mufflers willonly remove noise due to discharge gas pulsations.If the noiseis due to vibration, Vibration absorber should be added to the discharge line and possibly the suction line.
5.Asingle Mufler may be installed ona common discharge line.However,itis also acceptable to install one Mufflerpercompressoron parallel racks.
