Normal upflow installationwill be in a closet or basement. If installed in a closet, thecloset should have a platform framed in, with an openingat the top of the platform centered in the closet. Connectthe supply air outlet to a plenum. Install return air grillesfrom outside the closet to space below the platform.Platform must be at least 12” above the floor. If installedin a basement, run supply and return duct work inaccordance with local codes.HORIZONTAL APPLICATION:Horizontal applications will normally be used in an attic orcrawl space. This type of installation requires a return airduct be attached to the unit inlet. The opposite end of thereturn air duct is attached to a return air filter grille throughthe ceiling or wall. Remove air filter from unit if filtergrille is used. The unit is shipped in right to leftconfiguration. For left to right applications (beforeconnecting drains, refrigerant or water piping) remove coiland doors and move horizontal pan to right side. Reinstallcoil and doors.DOWNFLOW APPLICATION:Contact distributor for proper downflow conversion kit.Hydronic heat units cannot be used in the down flowposition.CAUTION:It is mandatory to use an emergency auxiliary drain panwith any coil or air handler installed in an attic or abovea finished ceiling.ELECTRICAL WIRING:Refer to the unit nameplate for specific electrical data.CAUTION:Disconnect power at main fuse or circuit breakerdistribution panel before wiring unit to prevent shock orfire hazard.POWER WIRING:Unit is suitable for use with copper conductors. Tighten allwire connectors. Take care not to damage heater ceramicinsulators on electric heat models. For correct field wiresize see unit nameplate and field wiring table insideelectrical compartment door. Use 75 C minimum wire inunit wiring compartment. Units larger than 10 KW willrequire multiple sets of power conductors.NOTE: See unit for complete wiring diagram located onblower housing.CONTROL WIRING:Field connections to the low voltage leads are made usingappropriate field supplied wiring connectors. Consultinstallation instructions provided with accessory items forspecific information on control wiring. Use 18 AWGminimum copper conductors for control wiring up to 50’between units. 16 AWG control conductors arerecommended for lengths between 50’ and 100’. Class 2wiring is acceptable. Take care not to short control leads,transformer burnout could result. Some manufacturer’soutdoor units are equipped with a 24 volt controltransformer. If this type of outdoor unit is used with thisair handler, use a thermostat with isolating contacts toprevent inter-connection of two separate Class 2 circuits.Set thermostat heat anticipator at 0.15 amps for units12KW or smaller, set at .30 amps for 15 KW and larger.BLOWER MOTOR:CONSTANT SPEED MOTOR:Two factory selected motor speed leads are connected tothe blower relay to provide automatic speed change forheating and cooling airflow volumes. The pre-selectedmotor speeds would normally not have to be changed inthe field. All models contain a blower time delay relay(TDR 10-30 seconds) that delays the blower turning onand off when the thermostat calls for “Fan Only” or“Cooling”. The TDR improves energy efficiency.VARIABLE SPEED MOTORS:Electronic commutated and constant torque motors arefactory programmed and cannot be re-programmed in thefield. ECM motors have (4) jumper settings, and CTmotors have (5) speed taps. Refer to blower performancedata located in the SunTherm Technical Guide forselection of jumper or tap settings that best fits thisapplication.NOTE: All 208/230 volt motors are factory programmedfor “0” second fan “ON” delay for use with electric heat.Motor must energize with electric heat. All 115 voltmotors are factory programmed for “30” second fan “ON”delay for use with hydronic heat.MS-Installation Instructions 052209-5

The evaporatorcoils have sweat copper connections. Refrigerant linesshould be soldered with silver solder or other hightemperature brazing alloy. The suction must be insulatedfor satisfactory operation. An oil trap must be installed inall vertical suction risers. An additional oil trap must beinstalled every 15’ for risers over 15’ in height. If thecondensing unit is located over the evaporator coil, an“inverted” oil trap must be installed at the top of thesuction riser. Horizontal suction line runs should be sloped1” every 20’ toward the condensing unit. The manufacturerrecommends that dry nitrogen be flowed through therefrigerant lines during the soldering operation. Liquid lineis capped. NOTE: Pressure drop in liquid must not exceed30 psi or erratic operation and thermostatic expansiondamage will occur.CHILLED WATER PIPING:All piping must be supported independent of coils toprevent vibration and stress on coil headers. Swing jointsor flexible fittings must be provided to absorb expansionand contraction strains. Rigid piping reduces theeffectiveness of vibration isolators.Water piping should always be connected so that theentering water is on the leaving side of the coil. Coils mustbe adequately vented in order to prevent air binding. Unitsare provided with manual air vents mounted through themanifold panel.HOT WATER PIPING:If a residential water heater is used for space heating water,do not exceed a distance of 70’ between the air handler andthe water heater. The water heater should be the quickrecovery type. Air handler and water heater must belocated indoors and not subject to freezing temperatures.WARNING:Air handler must be located so that if any connectionsshould leak, water will not cause damage to the adjacentarea. When such locations can’t be avoided, a suitabledrain pan should be installed under the air handler, notover 1-1/2” deep, with minimum length and width at least2” greater than the air handler dimensions andconnected to an adequate drain. Under no circumstancesis the manufacturer to be held libel for any water damagein connection with this air handler.HOT WATER PIPING: Continued).Total piping should not exceed 140’. All piping should be¾” copper or approved PVC. It is recommended that thewater shut-off valve for the water heater be located closeto the water heater. Isolation valves are alsorecommended.It is recommended that any devices installed, which couldcreate a closed system, have a by-pass and/or the systemhave an expansion tank to relieve the pressure built up bythermal expansion in the water system.WARNING:Toxic chemicals such as used for treatment of boilers ornon-potable water heating appliances shall never beintroduced into a potable water space heating system.WARNING:When the system required water at temperatures higherthan required for other uses, a means such as a mixingvalve shall be installed to temper the water for those usesin order to reduce the scald hazard potential.After piping has been installed, allow the system to fillwith water and check connections for leaks. To insurecomplete filling of the system, follow start-up procedure.CONDENSATE DRAIN PIPING:The air handler “A” coil drain pan has two ¾” NPTfemale primary and two secondary connections (left orright hand). Horizontal pan has two ¾” NPT female, oneprimary and one secondary.
