Unpacking Your Freezer
1.Removeall packagingmaterial;thisincludesthefoambaseandalladhesive
tape holding the freezer accessoriesinside and outside.
2.Inspectandremoveanyremainsofpacking,tape orprintedmaterialsbefore
powering on the freezer.
Adjusting Your Freezer
1.Yourfreezer isdesignedforfreestanding installation only.It shouldnotbe
recessed or built-in.
2.Placethe freezer on afloor strong enough tosupport it fullyloaded.
3.When movingthefreezer,nevertiltitmorethan a45-degreeangle.Thiscould
damage the compressor and the sealed system.
4.Ifthe freezer istilted letitstandinan uprightposition for atleast24 hoursprior
toplugging.Thisistoallowthe refrigerant tosettle.
·ProperAirCirculation
l Toassureyourfreezer worksatthemaximumefficiencyitwasdesignedfor,
you shouldinstall it inalocation where there isproper aircirculation,
l Plumbing and electricalconnections.
l The following are recommended clearancesaround the freezer:
Sides ..2”(50mm)

Installing Casters(delete?)
Your freezer can be equipped withcastersfor easy moving.Werecommend
installing castersbefore using the freezer.Install following theseeasysteps:
1.Removethe food basket from the freezer.
2.Slowlytilt the freezer on its side.
3.Taponecasterintothebottomofthe freezer.Fastenthecasterintoplace

12.1SystemTroubleshooting
12.1.1Servicing freezer
(1)Check thewholecircuitoffreezer, iftherearewireconnections

(2) Check theinsulation ofthewholefreezer.Atnormal situation,
theresistance isgreaterthan2mebohms;ifitisless than2
mebohms, please make afurthercheck ofthefreezerresistance.
Set thevoltmetertoR1Ohm position, putthetwovoltmeterleads

ofodometer. Thenormal valueisseveral Ohm totensofohm. If
theresistance iszero, meansthat thereisashortinthefreezer
circuitor thereisashortcausedbyabadcompressor or fan
motor. Thereason shouldbefound outand repaired. Ifthe
resistance istoo bigor infinite, thismeansthat thereisbroken
circuit, please check and solve it.
Afterthe abovechecks, the freezerwill not haveany
