Introduction
Laird Outdoor Cooler Series is an Air to Air thermoelectric assembly that uses impinge-
mentflowtotransferheat.Itoffersdependablecompactperformancebycooling
objectsviaconvectionandisdesignedtoprovidecoolingforawiderangeofoutdoor
environments in the telecom, industrial and kiosk markets. They are intended to work
inanopenloopsystemorifpurchasedwithabi-directionalcontrollerinaclosedloop
system with feedback control.
Heat is absorbed and dissipated thru high density heat exchangers equipped with air

Installation and Operation Instructions
ReducingthepassiveheatloadiscriticaltoyieldthehighestefficiencyoutofanOutdoor
Cooler and maximize service life. It is important to insulate the walls of an enclosure
withasmuchinsulationmaterialaspermissiblewithoutinterferingwithnearbyelec-
tronicsorsystemlevelobstructions.Properinsulationoftheenclosurecanresultin
sizing a smaller Outdoor Cooler unit and power supply, which can reduce total system
costs.
The Outdoor Cooler is mounted onto a cabinet wall with “Hot Side” mounted external
to cabinet. This is required to dissipate heat out of the cabinet. It is also important to
havegoodventilationonthehotsidetotransportheatexhaustawayfromthecabinet.
At minimum of one fan thickness is required from the wall surface to the exterior face of
the fan to allow air to enter into the fan and transport the exhaust through the ducted
shroud.
Outdoor Coolers cool below ambient, so it is important to run them in a cabinet that
is sealed from the outside environment. If the dew point is reached, then moisture in
the air will condense onto the cold side heat exchanger. Access to outside air exchange
canacceleratethemoisturecondensationrateandcauselargeamountsofmoistureto
accumulateonthecoldsurfacesoftheOutdoorCooler,whichcoulddegradeoperation
lifeovertimeifthesystemisnotdesignedtodraincondensation.Itisrecommendedto
mounttheOutdoorCoolerinaverticalorientation,socondensationrunsoffthecold
side heat exchanger. If the enclosure cannot accommodate this, then the Outdoor Cool-
ershouldbeinstalledataminimum15degreeangleinhorizontalorientationtoallow
forcondensationtorunoffthecoldsideheatexchanger.
The Outdoor Cooler must be protected from vandalism or external forces that may
bump up against unit and cause damage.
Mounting & Hardware
The enclosure should be sealed from the outside environment by maintaining good
compression between the Outdoor Cooler and cabinet wall. The Outdoor Coolers are
designed to be through mount, so a cut out on the enclosure wall will be required to
accommodatethecoldsideheatexchanger.Referencethebelowdiagramformounting
holelocationsandcoldsideheatexchangerdimensions.Thecutoutshouldbe2.5mm’s
largerthanthecoldsideheatexchanger.Eightmountingholesareavailabletofasten
theOutdoorCoolerunittocabinetwall.Themountingholesaredesignedtoaccom-
modate M5 machine hardware as shown in diagram. External tooth lock washers are
recommendedtopreventOutdoorCoolerfromlooseningovertime.
