Installation and AccessoryParts
Unpacking Your Ice-linedrefrigerator
1.Removeall packagingmaterial;thisincludesthefoambaseandalladhesive
tape holding the refrigerator accessoriesinside and outside.
2.Inspectandremoveanyremainsofpacking,tape orprintedmaterialsbefore
powering on the refrigerator
Adjusting Your Refrigerator
1.Your refrigerator isdesignedforfreestandinginstallation only.Itshouldnotbe
recessed or built-in.
2.Placethe refrigerator on afloor strong enough tosupport it fullyloaded.
3.When moving therefrigerator,never tiltitmore than a45-degreeangle.This
coulddamage the compressor and the sealed system.
4.Ifthe refrigerator istiltedletitstandinan uprightposition foratleast24hours
prior toplugging.Thisistoallowthe refrigerant tosettle.
·ProperAirCirculation
l Toassureyour refrigeratorworksatthemaximumefficiencyitwasdesigned
for, you shouldinstall it inalocation where there isproper aircirculation,
l Plumbing and electricalconnections.
l The following are recommended clearancesaround the refrigerator:
Sides ..2”(50mm)Top. 2”(50mm)

MAINTENANCESERVICEAND TROUBLESHOOTING
12.1SystemTroubleshooting
12.1.1Servicing refrigerator
(1)Check thewholecircuitofrefrigerator, iftherearewire
connectionscameoff, anywires broken, or ashortcircuit.
(2) Check theinsulation ofthewholerefrigerator.Atnormal
situation, theresistance isgreaterthan2mebohms;ifitisless
than2mebohms, please make afurthercheck oftherefrigerator
resistance. Set thevoltmetertoR1Ohm position, putthetwo
voltmeterleadspencilsintoLand Nterminalsrespectively, watch
theindication ofodometer. Thenormal valueisseveral Ohm to
tensofohm. Iftheresistance iszero, meansthat thereisashort
intherefrigerator circuitor thereisashortcausedbyabad
compressor or fanmotor. Thereason shouldbefound outand
repaired. Iftheresistance istoo bigor infinite, thismeansthat
thereisbrokencircuit, please check and solve it.
Afterthe abovechecks, the refrigeratorwill not haveany
electrical problemand you can switchpoweron forfurther
completelycheck.

(1) Atnormaloperationconditions,thetemperaturearoundthe
surface ofrefrigeratorevaporator isnearlythesame;the
thickness offrost layerissimilar.Ifthereisno frost at thesurface
ofevaporator (bedtyperefrigerator at all ofitsinnerwall),or only

operation ofrefrigeration systemisnotnormal,therefrigerantis
insufficientor thereisleakage.
(2) Check thesystemtubing and make surethereisnoleakage,
especiallyat thejointconnections.Refrigeranthas good
