INSTALLATION NOTESThe LiftAire Series of air conditioners are specificallydesigned and constructed for use on new elevatorinstallations, modernizations and retrofits of existing elevatorcabs. They are provided with all the materials needed toproperly cool and/or heat an elevator cab. To ensuremaximum efficiency and operation, the following guidelinesshould be adhered to:1.Supply and return registers in the cab should notrestrict airflow into and out of the cab. Anyresistance of the airflow will limit the effectivenessof the unit and create wind noise. The return air andsupply air registers should be as far away from oneanother as possible to ensure proper air circulation inthe cab and back to the air conditioner.2.While the installation kit provides a sufficientamount of supply and return air flexible duct, inorder to limit airflow resistance, all ductconnections should be the most direct and theshortest possible. Cut any extra flexible duct notrequired, connect flexible duct per previousinstallation instructions and discard any extramaterial.3.Ensure that the thermostat is installed in thereturn duct or the cab. If using the standardthermostat, check that the temperature and operationsettings are correct. If using the automaticthermostat, make sure the unit is programmed forthe type of operation you require. When thermostatis installed in the cab, it must be able to sense cabtemperature to operate properly. If placed within the
4.fixture area of the cab, there must be a perforatedcover to allow cab air access to the thermostat.Locating the thermostat anywhere else affects theproper operation of the LiftAire unit and cooling ofthe elevator cab as designed.5.All supply and return registers with duct work intothe cab must be manufactured and installed toprevent any air leaks and losses of the cold supply airfrom the air conditioner and return air back to the airconditioner.If you are retrofitting an existing cab, it may not benecessary to use the fan supplied in the originalcab. The LiftAire air conditioner has a fan that willrun continuously with proper settings of thethermostat. If you allow the cab fan to operateduring normal conditions you will bring hot, cold orhumid hoistway air into the cab, thereby defeatingthe purpose of the air conditioner and itseffectiveness. If it is permitted, remove the originalfan to prevent warm hoistway air from entering thecab during ascent and descent of the elevator. Ifnecessary, you can use he original fan’s opening forthe return air register, provided it has 79 squareinches of open area and is far enough away from thesupply air register to ensure proper recirculation ofthe cool air. If using the LiftAire on a newinstallation, a cab fan is probably not required. If aseparate cab fan is required it is recommededthat the cab fan operate only during powerloss. In addition, the cab fan should utilize a springloaded or powered louver than opens during cab fanoperation. This prevents unregulated hoistway airfrom entering the cab during air conditioneroperation.6.Never install the condensate evaporator under thereturn or supply air ducts. This can cause wateraccumulation, damage to the ducts and damage tothe cab.7.It is the responsibility of the installer to ensure thatthe installation meets any and all building, electricaland other applicable codes.DANGER - SHOCK HAZARDDo not drill any openings into this air conditioner. Whenattaching any collars, ducts or adapters directly to the airconditioner, use only the pilot holes provided. Drillingnew openings or inserting screws may damage either therefrigeration circuit or electrical wiring, causing possibleequipment damage, personal injury or death.9. MAINTENANCE INSTRUCTIONSThe LiftAire Series of air conditioners require very littlemaintenance during normal operating conditions. Thefollowing are general requirements that should be performedevery 4-6 months.1.2.Air filters should be inspected and washed on aregular basis. Clogged filters will produce a loss ofair volume and possibly damage equipment. Do notoperate the unit without a return air filter. Thefilters are reusable after being washed.Evaporator and condenser coils should be inspectedand, if dirty, cleaned on a regular basis. Remove byhand any paper or debris that might have collectedon the coils and blow compressed air through thecoils. This should not have to be done very oftenunless the shaftway and installation are in a verydirty environment.3.Inspect and clean the condensate drain pan. Ensurethat the drain hole and hose are clear of debris toallow any condensate to properly drain.4.If a condensate evaporator is used, inspect to ensurethere is no debris on the guard or in the evaporatorpan. Ensure drain hole and hose are clear of debris.5.If an automatic thermostat is used, check the LCDdisplay and observe if the word “BATTERY” isflashing. If it is displayed, the “AA” alkalinebatteries are low and should be replaced. Seethermostat operating manual for battery replacementinstructions.
10. 115 (240) VOLT AC ELECTRICAL WIRINGWARNING - SHOCK HAZARD4.This unit is equipped with high and low pressureswitches to protect against fan failure and refrigerantloss. If either activates, the unit will lock out untilservice personnel inspect and repair any problem andreset the unit by depressing the reset button locatedon the air conditioner.5.The unit is equipped with a normally open contact(rated 30 amps at 115 volts). This contact closeswhen the high or low pressure switches are activatedor when line voltage is interrupted. It can be usedfor customer external alarms or operation.6.If line voltage is interrupted or there is a powerfailure, there will be a three (3) minute time delayafter resumption of power before compressor will beallowed to restart and the air conditioner will resumeoperation.To prevent the possibility of severe personal injury orequipment damage due to electrical shock, always by surethe electrical power is disconnected or off beforebeginning installation.1.Power supply wire size should be determined percode and losses for long cable runs should be takeninto account to insure the proper voltage to the airconditioner at unit startup amperage.2.This air conditioner contains a compressorrefrigeration system and requires power from a 115(240) volt electrical circuit. The circuit connects toterminal lugs inside the unit.3.High Voltage Routing Specifications - When routingthe high voltage supply wiring, the followingguidelines must be followed: High voltage wiring must be routed throughthe separate opening in the outer cabinet ofthe air conditioner. This opening is shownon Figure 1 as Field Wiring Line VoltageAccess. It is a 7/8 inch diameter openingfor ½ inch conduit. Do not allow excess wiring to contact theelectrical terminals or allow sharp screwends and edging that can damage the wireinsulation.CAfter connecting ground wire to groundinglug, verify the grounding wire cannot comeinto contact with any high voltageterminals.DANGERWhen using non-metallic sheath supply cables (Romex,etc.); if allowed by building, electrical or applicable codes,strip sheath back to expose 4-6 inches of the supply leads.Strip the individual wire lead ends for wire connection(about 3/4 inch bare wire). Insert the supply wires into
