SPXB / SPXB-HP SeriesSingle Package Vertical Unit
Straight Cool and Heat Pump3/4 through 2 tons, up to 10 kW Electric Heat
The SPXB Series "Suite 20" is a compact, through-the-wall single package vertical HVAC unit that delivers conditioned air from a single unit to multiple rooms. The SPXB series is available in straight cool (SPXB) or heat pump (SPXB-HP) models. Having a small footprint (20" X 20") allows the SPXB to use a minimal amount of floor space. The SPXB installs easily into a closet having an exterior wall. Like your home, a standard wall mounted thermostat controls the SPXB unit. Applications for the SPXB include:
•Hotels/Motels •Highriseapartments/Condominiums •AssistedLiving/Independentcarefacilities •Studenthousing •Manufactured/Modularbuildings
Standard Features: (see pages 4 and 5 for further information) • Completelypre-chargedwithenvironmentallyfriendly R-410A refrigerant • Easyaccessforin-placeserviceofmostcomponents • Multi-functionmicro-processorboardthatincludesthe following functions: Evaporator coil low temperature protection Low ambient lockout ECMmotorutilizedonSPXB18&24models Random restart Compressor restart delay Front desk control capability Fan-off delay in the cooling mode Low voltage fuse protection • Servicedisconnect • Completelyinsulatedcabinetforsoundattenuationand weather infiltration • Adjustablefreshairdamper • Notoolneededtoreplacethefilter • Weight-supporting,singlepiecewallsleeves(except side access sleeves) for various wall thicknesses from 5" to 20" • Sleeveshaveprimarycondensatedrainconnection with secondary overflow to building exterior • Allsleevesareshippedwithaweatherguard • Flushtypeexteriorarchitecturalgrilles

FEATURES AND BENEFITS
1. Solid State Circuit Board -Incorporatesthefollowingcontrolfeatures:
• Evaporator coil low temperature protection –Duringthecoolingmode,shouldtheevaporatorcoilexperienceeither a low temperature condition that could result in ice build up on the coil or a reduced air flow situation, a temperaturesensorattachedtothecoilwillde-energizetheSPXBunit.Thesensorwillre-energizetheSPUunit when the coil warms back up.
• Low ambient lockout – Locks out compressor when the sensor registers temperatures of 40 degress F and below to extend compressor life.
• Random restart – When power is turned on after a power outage, a built-in random restart (3 to 4 minutes) prevents all compressors from restarting simultaneously.
• Compressor restart delay – This delay ensures that system pressures are allowed to equalize before acompressor restart, which extends compressor life.
• Front desk control – When wired to a front desk console, each unit can then be enabled or disabled from the front desk, thus saving the energy used to condition unoccupied rooms.
• Fan delay – A fan delay allows the evaporator blower to continue running for up to 45 seconds after the thermostat issatisfied.Thisfeaturemaximizescoolingperformance.
• Low voltage fuse protection
2. Service Pullout - Factory installed for service convenience and maintenance.
3. Adjustable fresh air (manual) - To meet code requirements for fresh air introduction. When opened, the fresh airvent(seeFigure8)allowsupto50CFMofoutsideairtobeintroducedintotheequipmentcloset.Theairthenmixes with return air entering the closet through the return air grille.
4. Wall-mounted thermostat –(See“accessories”,P.8)TheSPXB is easily controlled by a standard low voltage wall thermostatratherthancomplicatedunit-mountedcontrols.Lowvoltagewiresare“stubbed”outtheleftsideofthecabinet.

NOTE: A solid door or panel in front with a side wall return air grill will result in lower sound levels.
Figure 25. Wall Sleeve – (See Figures 1, 4 and 5) Rear or side install
wall sleeves are provided for installation during rough-in and, when ready, the SPXB unit is simply slid into the sleeve and the ductwork and electrical connected. The sleeve is a weight-bearing sleeve that supports the entire weight of the SPXB unit and provides a weather tight seal against wind andwaterinfiltration.A3/4”maleNPTfittingisprovidedinthe bottom of the sleeve for field connection to a condensate riser. Four wall sleeve depths are available to accommodate wallthicknessfrom5”to20”.Eachsleeveincludesafactoryinstalled“weatherguard”tocoverthesleeveopeningduringconstruction.
6. Unique “Sleeve Drain” Condensate System - (Also see Figure 4) A factory installed drain line connects the evaporator drain pan to a vertical pipe connection in the SPXB base pan. Evaporator condensate is delivered from
the SPXB unit to a catch tray in the wall sleeve and exits the sleeve through the3/4”maleNPTfitting.Thisdesignallows the plumber to completely pipe the drain to a condensate riser during the rough-in stage, thus eliminating condensate connection problems usually encountered when trying to connect the HVAC drain to the riser after the HVAC unit is installed in the closet. This features also allows the SPXB unit to be removed for service without disconnecting the condensate
piping! This configuration does not require any additional closet space to make the drain connection, as do some competitive products.
7. Secondary overflow: Ifforanyreasontheprimarycondensate riser becomes clogged, water will fill the catch tray and then be diverted through the sleeve to the exterior of the building, rather than be allowed to overflow into the closet or living area. Rain water entering the sleeve is automatically diverted to the 3/4" sleeve drain.
8. Ductable return air – Return air can be ducted to the unit. However, most installations would not normally require ducted return air.
9. New “Flush Style” Architectural Grille – (See Figure 6) This new grille is an attractive extruded aluminumarchitectural grille that attaches to the outside face of the wall sleeve. The blades of this unique grille recess into the wallsleeveforaneat,“flush”appearance.Grilles installfrom the insideofthewallsleeve.Donot install the SPXB unit into the sleeve before installing the grille.
10. Filter Brackets – (SeeFigure7)FilterBracketsandthrowaway filter are shipped with each unit and are field installed over the unit’s evaporator coil.
11. Insulation kit (#91K01) - The interior of all SPXB's is lined with 1/2" fiberglass as standard. The 91K01 kit is designed to be used in any application where additional insulation is desired.Thekitincludesthreesectionsof5/8"foilfacedductboard insulation that are screwed together in the field and cover the three sides on the condenser section.

Oneendofa3”aluminumventpipeisconnectedto the condenser venturi and the other end is connected to the side of the SPXB cabinet. A mesh screen is installed inside the vent pipe and a metal plate on the side of the cabinet covers theopeningoftheventpipe.Upto50CFMoffresh air is introduced into the equipment closet by removing the metal cover plate. The fresh air then mixes with the return air and is then pulled through the evaporator coil and into the supply duct. The cover plate can be re-installed to par-tially close the fresh air opening if less than 50 CFMisdesired.Anexternalsourceofnegativepressure (i.e. a bathroom fan) could be used to introducemorethan50CFMoffreshair.Consultwith factory for further details.
