PRECAUTIONS
General Precautions (Cont'd)

• After disconnecting vacuumorair hoses, attachatag to
indicate theproper connection.
• Use only thefluids andlubricants specifiedinthis manual.
• Use approved bondingagent,sealants ortheir equivalents
when required.
• Use tools andrecommended specialtoolswhere specified
for safe andefficient servicerepairs.
• When repairing thefuel, oil,water, vacuum orexhaust
systems, checkallaffected linesforleaks.
• Dispose ofdrained oilorthe solvent usedforcleaning parts
in an appropriate manner.

Precautions forMultiport FuelInjection System
or ECCS Engine

• Before connecting ordisconnecting anyharness connector
for the multiport fuelinjection systemorEGM (EGGS control
module):
Turn ignition switchto"OFF" position.
Disconnect negativebatteryterminal.
Otherwise, theremaybedamage toEGM.
• Before disconnecting pressurizedfuellinefrom fuelpump to
injectors, besure torelease fuelpressure.
• Becareful nottojar components suchasEGM andmass air
flow sensor.

Precautions forThree WayCatalyst

If a large amount ofunburned fuelflows intothecatalyst, the
catalyst temperature willbeexcessively high.Toprevent this,
follow theinstructions below:
• Use unleaded gasolineonly.Leaded gasoline willseriously
damage thethree waycatalyst.
• When checking forignition sparkormeasuring engine
compression, maketestsquickly andonly when necessary.
• Donot run engine whenthefuel tank level islow, otherwise
the engine maymisfire causing damage tothe catalyst.
Do not place thevehicle onflammable material.Keepflamma-
ble material offthe exhaust pipeandthethree waycatalyst.

Engine Oils

Prolonged andrepeated contactwithused engine oilmay
cause skincancer. Trytoavoid direct skincontact withused oil.
If skin contact is.made, washthoroughly withsoap orhand
cleaner assoon aspossible.

HEALTH PROTECTION PRECAUTIONS

• Avoid prolonged andrepeated contactwithoils, particularly
used engine oils.
• Wear protective clothing,including impervious gloves
where practicable.
• Donot putoily rags inpockets.
• Avoid contaminating clothes,particularly underpants, with

oil.

• Heavily soiledclothing andoil-impregnated footwearshould
not beworn. Overalls mustbecleaned regularly.
• First Aidtreatment shouldbeobtained immediately foropen
cuts andwounds.
• Use barrier creams, applying thembefore eachwork
period, tohelp theremoval ofoil from theskin.

PRECAUTIONS
Engine Oils(ConI' d)

• Wash withsoap andwater toensure alloil isremoved (skin
cleansers andnailbrushes willhelp). Preparations contain-
ing lanolin replace thenatural skinoilswhich havebeen
removed.
• Donot use gasoline, kerosine, dieselfuel,gasoil,thinners
or solvents forcleaning skin.

• If
skin disorders develop,obtainmedical advicewithout
delay.
• Where practicable, degreasecomponents priortohandling.
• Where thereisarisk ofeye contact, eyeprotection should
be worn, forexample, chemicalgogglesorface shields; in
addition aneye wash facility should beprovided.

ENVIRONMENTAL PROTECTIONPRECAUTIONS

Burning usedengine oilinsmall space heaters orboilers can
be recommended onlyforunits ofapproved design.Theheat-
ing system mustmeettherequirements ofHM Inspectorate of
Pollution forsmall burners ofless than 0.4MW. Ifin doubt check
with theappropriate localauthority and/ormanufacturer ofthe
approved appliance.
Dispose ofused oiland used oilfilters through authorized
waste disposal contractors tolicensed wastedisposal sites,or
to the waste oilreclamation trade.Ifin doubt, contact thelocal
authority foradvice ondisposal facilities.
It is illegal topour used oilontothe ground, downsewers or
drains, orinto water courses.
The regulations concerningthepollution ofthe environment
will vary between regions.

Precautions forFuel
GASOLINE ENGINE:

For Europe

Unleaded gasolineofat least 95octane (RON)
CAUTION: Do not use leaded gasoline. Usingleaded gasoline willdamage
the catalytic converter.

Except Europe

Unleaded gasolineofat least 91octane (RON)

DIESEL ENGINE*:

Diesel fuelofat least 50cetane
If two types ofdiesel fuelareavailable, usesummer or
winter fuelproperly according tothe following temperature
conditions.
• Above -rc(20°F) Summer typediesel fuel.
• Below
-rc
(20°F) Wintertypediesel fuel.
CAUTION:
• Donot use home heating oil,gasoline, orother alternate
fuels inyour diesel engine. Theuseofthose cancause
engine damage.
• Donot use summer fuelattemperature below_7°C(20°F).
The cold temperatures willcause waxtoform inthe fuel. As
a result, itmay prevent theengine fromrunning smoothly.
• Donot add gasoline orother alternate fuelstodiesel fuel.

DESCRIPTION
Refrigeration Cycle
REFRIGERANT FLOW

The refrigerant flowisinthe standard pattern.Refrigerant flowsthrough thecompressor, condenser,
liquid tank,evaporator andback tothe compressor.
The refrigerant evaporation throughtheevaporator coiliscontrolled byan externally equalizedexpan-
sion valve, located insidetheevaporator case.

FREEZE PROTECTION

The compressor cyclesonand offtomaintain theevaporator temperature withinaspecified range.When
the evaporator coiltemperature fallsbelow aspecified point,thethermo controlamplifier interrupts the
compressor operation.Whentheevaporator coiltemperature risesabove thespecification, thethermo
control amplifier allowscompressor operation.

REFRIGERANT SYSTEMPROTECTION
Dual-pressure switch

The dual-pressure switchislocated onthe liquid tank.Ifthe system pressure risesorfalls outof
specifications, theswitch openstointerrupt compressor clutchoperation.

Fusible plug

Open attemperature above105°C(221°F), thereby discharging refrigeranttothe atmosphere. Ifthis plug
is melted andopened, checktherefrigerant lineand replace liquidtank.
