2.1. Adjustmentofprimarylatchswitch, secondarylatchswitchand
shortswitch.
1. MountthePrimarylatchswitch, theSecondarylatchswitchand
theshortswitchtothedoorhookassemblyas showninILL.
NOTE:
Nospecificindividual adjustments during installation ofthe
Primarylatchswitch, SecondarylatchswitchorShortswitchto
thedoorhookarerequired.
2. Whenmounting thedoorhookassemblytotheovenassembly,
adjust thedoorhookassemblybymoving itinthedirection ofthe
arrowsintheillustration sothat theovendoorwill nothaveany
playinit. Check forplayinthedoorbypulling thedoorassembly.
Make surethat thelatchkeysmovesmoothlyafteradjustmentis
completed. Completelytightenthescrewsholding thedoorhook

3. Reconnect theshortswitchand check thecontinuityofthe
monitorcircuitand all latchswitches againbyfollowing the
componenttest procedures.

2.2. Measurementofmicrowaveoutput
Theoutputpowerofthemagnetron canbedeterminedbyperforming IECstandard test
procedures. However,duetothecomplexityofIECtestprocedures, itisrecommendedtotestthe
magnetron using thesimplemethod outlinedbelow.
NecessaryEquipment:
*1literbeaker*Glass thermometer/ *Wristwatchor stopwatch
NOTE:
Check thelinevoltageunderload.Low voltagewill lowerthe
magnetron output. Take thetemperaturereadingsand heating time
as accuratelyas possible.
1. Fill thebeakerwithexactlyoneliteroftapwater.Stirthewater
using thethermometerand recordthewater’stemperature.
(recordedas T1).
2. Place thebeakeron thecenterofglass tray. / Set theovenforHigh
powerand heat itforexactlyoneminute.
3. Stirthewateragainand readthetemperatureofthewater.
(recordedas T2).
4. Thenormal temperaturerise at High powerlevel foreachmodel is
as shownintable.

WARNING
Check for radiation leakageaftereveryservicing.
Shouldtheleakagebemorethan2mW/cm2(1mW/

immediately. Afterrepairing or replacing any
radiation safetydevice, keepawrittenrecord for
futurereference, as requiredbyD.H.H.S. and Health
and WelfareCanadaregulation. Thisrequirement
mustbestrictlyobserved. Inaddition, theleakage

1. Pour275 ±15cc (9ozss±1/2oz)of20°C±5°C(68° ±9°F)waterina
beakerwhichisgraduatedto600cc, and place inthecenterofthe
oven.
2. Set theradiation monitorto2450MHzand use itfollowing the
manufacturer'srecommendedtest proceduretoassurecorrect
results.
3. Whenmeasuring theleakage, alwaysuse the2inch(5cm)spacer
suppliedwiththeprobe.
4. Tapthestartpadorset thetimerand withthemagnetron
oscillating, measuretheleakagebyholding theprobe
perpendiculartothesurface being measured.
3.2.1. Measurementwiththeouterpanel removed.
Wheneveryou replace themagnetron, measurefor radiation leakagebeforetheouterpanel is
installedand afterall necessarycomponentsarereplacedor adjusted. Special careshouldbe
takeninmeasuring around themagnetron.
WARNING
Avoidcontacting anyhigh voltageparts.
3.2.2. Measurements withafullyassembledoven.
Afterall components, including outerpanel arefullyassembled, measurefor radiation leakage
around thedoor periphery, thedoor viewing window, theexhaustopening and airinletopenings.
3.3. Recordkeeping and notification aftermeasurement
-Afteranyadjustmentorrepairtoamicrowaveoven, aleakage
reading must betaken. Recordthisleakagereading on therepair
