1 Free return installation (non-ductedreturn air): The furred down area mustbe completely sealed (except returnair grille) to ensure that all return air ispulled from the conditioned space andnot from other areas of the buildingstructure. Access must be provided for ser-vicing the unit . If this access isprovided by a removable ceilingpanel, ample space must be allowedfor removal of the blower panels and toprovide access to electrical andplumbing controls. While most fancoil UNITS are Listed for installa-tions with zero clearance to combus-tible materials, reference should bemade to the marking on the particularunit being installed where specific in-formation regarding clearances is - HYX - HXX SERIES HORIZONTALFAN COIL UNITSINSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONSGENERALThe manufacturer assumes no re-sponsibility for equipment installed inviolation of any code instructions give informationrelative to the installation of these fancoil UNITS only.

When received, a visualinspection of all cartons should bemade immediately. Any evidence ofrough handling or apparent damageshould be noted on the delivery receiptand the material inspected in the pres-ence of the carrier s representative. Ifdamage is found, a claim should befiled against the carrier COIL UNITThe installer must adhere strictly toall local and national code require-ments pertaining to the installation ofthis equipment. These UNITS are de-signed for installation in a horizontalposition above a dropped ceiling.** WARNING ** unit must not be operatedduring building constructiondue to excessive airborne dustand debris.

3 The unit must notbe operated under anycircumstances without an airfilter in DISTRIBUTIONDUCTSAll duct work must be installed inaccordance with National Fire Protec-tion Association Codes 90A and should be adequately insulatedto prevent condensation during thecooling cycle and to minimize heatloss during the heating cycle. Allreturn air must be filtered to preventL239 08/10** WARNING **Extreme caution must betaken that no internal damagewill result if screws or holes aredrilled into the cabinet.**WARNING TO INSTALLER, SERVICE PERSONNEL AND OWNER** Altering the product or replacing parts with non authorized factory parts voids all warranty or implied warrantyand may result in adverse operational performance and/or a possible hazardous safety condition to servicepersonnel and occupants.

If thereis no ducted return, applicable instal-lation codes may limit the unit toinstallation only in a single story resi-dence. In many cases it is accept-able to use ducting of the same sizeas the fan coil connections. However,unique arrangements or long ductruns must be confirmed by a localprofessional. The manufacturer willnot be responsible for All wiring must comply with localand national code are provided with wiring dia-grams and nameplate data to provideinformation required for necessaryfield wiring. On some unit modelsremote control boxes are furnishedfor field installation.

5 In these in-stances care should be taken to as-sure that the control box used is thesame as that indicated by the mark-ing on the unit . The control boxshould be located as near the unit aspossible in a location readily acces-sible for servicing. Wiring betweenthe control box and the unit must bein accordance with the diagrams pro-vided. The field wiring between thecontrol box and the motor junctionbox must be installed using eitherflexible metal conduit or armoredcable with sufficient length to allowremoval of the blower section forservice access to the heater ele-ments and thermal outputs of the twotransformers by using a thermostatwith isolating of this fan coil shouldonly be performed by a licensed con-tractor to ensure proper installationand the safety of the installer.

6 Thefollowing are some precautions to befollowed for typical installations. Always use proper tools and equip-ment. No wiring or other work should beattempted without first ensuring thatthe fan coil is completely discon-nected from the power source andlocked out. Always verify that a goodground connection exists prior to en-ergizing any power sources. Always review the nameplate oneach unit for proper voltage and con-trol configurations. This informationis determined from the componentsand wiring of the unit and may varyfrom unit to unit . When soldering or brazing to theunit, it is recommended to have a fireextinguisher readily available. Whensoldering close to metering devices orother components, heat shields orwet rags are required to prevent dam-age.

7 Use the directional arrows or otherinformation on the filter to determinethe proper flow direction. Ensure that the air distribution sys-tem does not exceed the externalstatic rating of the fan coil UNITS are designed forquiet operation, however, all air condi-tioning equipment will transfer someamount of noise to the conditionedspace. This should be taken intoconsideration when planning the lo-cation of the is important to ensure that the fancoils are securely mounted and thestructure is sufficient to support theweight of the equipment. All anchorsfor mounting the equipment must beplaced and sized to ensure a safe anddurable UNITS are provided with four(4) mounting slots. Metal washersand nuts of the proper size are to beprovided by the installer.

8 When nec-essary use shims to obtain the properlevel. This will ensure that the con-densate will drain from the unit .** WARNING **When connecting piping tofan coil UNITS , do not bend orreposition the coil header tub-ing for alignment could cause a tubing frac-ture resulting in a refrigerantleak when pressure is appliedto the system.** WARNING **Do not touch any rotatingcomponent with any to the equipment andpersonal injury can occur.** WARNING **Any devices such as fanswitches or thermostats thathave been furnished by thefactory for field installationmust be wired in strict accor-dance with the wiring diagramthat is supplied with the to do so could resultin damage to componentsand will void all warranties.

9 When the fan coil unit is in operationcomponents are rotating at highspeeds. UNITS must be installed level toensure proper drainage and opera-tion. Check unit prior to operation toensure that the condensate water willdrain toward the drain connection. Anoverflow drain or an auxiliary drain panunder the fan coil may be required asa back up to a clogged primary drain. Be sure that the drain pan is freefrom foreign material prior to start up. Check filter media installation toensure that it is installed UNITS are provided with a Class2 transformer for 24-volt control cir-cuits. Should any add-on equipmentalso have a Class 2 transformer fur-nished, care must be taken to preventCOOLING COIL PIPINGThe HX fan coil UNITS are suppliedwith a direct expansion refrigerantcoil.

10 The suction and liquid refrigerantlines must be sized in accordancewith the outdoor unit manufacturer drain lines must beinstalled with adequate slope awayfrom the unit to assure positive drain-age. Since the drain pan is located onthe suction side of the blower, anegative pressure exists at the drainpan and a minimum trap of 1 inchmust be provided in the drain line toassure proper drainage.** WARNING ** Always wear eye protection. When fan coil is operating,some components are operatingat high speeds. Personal injurycan result from touching theseitems with any object All electrical and serviceaccess panels must be returnedand secured in their properplace. Clear surrounding area of alltools, equipment and debris.
