GENERALPuronR UnitsThis installation instruction manual describes theinstallation of electric heaters and associated fuseblock/field power termination kits (single point box orSPB) on small rooftop units in nominal cooling capacitiesfrom 3 to 15 tons. These rooftop units use Puronrefrigerant (R-410A). See Package Usage tables on page2 for applicable unit models. Unit types include coolingunits (AC) and heat pumps (HP) distributed over severalchassis sizes. Unit AC--1, AC--2, HP--1, HP--2 areidentified.This information does not include selection data. Refer toproject plans, job submittals and selection programs forheater and field power termination/SPB kit usage.Some electric heaters used on these Puron (R-410A) unitsmay also be installed in earlier R-22 rooftop units. Referto Form 50-8SI or IIK-548-36-49 for installationinstructions on heater packages CRHEATER101A00through 119A00 with earlier models. Contact your localdistributor office for a copy of this form.

Electric HeatersHeaters are shipped with one heater per carton. Thecarton is marked with a Sales Package Number. On allheaters except CRHEATER101A00 through 119A00, theheater Model Number (as marked on the heater infoplate)is the same as the Sales Package number. OnCRHEATER101A00 through 119A00 heaters, the value inposition 9 of the part number differs between the salespackage part number (value is 1) and bare heater modelnumber (value is 0). (See Table 1.)The heaters are modular in design, with heater framesholding open coil resistance wires strung through ceramicinsulators, limit switches and one or two controlcontactors. Power conductors are attached. One or twoheater modules may be used in a unit.Heater modules are installed in the compartment belowthe indoor (supply) fan outlet. Access is through theindoor access panel. Heater modules slide into thecompartment on tracks along the bottom of the heateropening. (See Fig. 13.)NOTE: The following heaters do not use the slide track --CRHEATER101A00--109A00, 297A00, 298A00, and301A00.

Not all available heater modules may be used in everyunit. Use only those heater modules that are UL listed foruse in a specific size unit. Refer to the label on the unitcabinet for the list of approved heaters. (See Fig. 1 and2.) See Appendix C for electric heater module data.

Single Point Boxes and FusesThe Single Point Box kits provide a field powertermination location plus an enclosure for heater fuseswhen required by code. The SPBs are installed under theunit’s main control box and include a hinged cover plusall internal wiring. Minimum components of the SPB area field power terminal block with tap conductors (toconnect to the unit’s main control box field terminals).Maximum component population includes up to five fuseblocks.Fuses for electric heater circuits are required and providedwhen the unit’s MOCP exceeds 60-A or when the totalheater Full Load Amp value exceeds 48-A. When fusesare required and provided, the cooling circuit is alsoprovided with fuse protection; some units require minorwiring changes in the main control box (see section onTB10 terminal blocks).

No FusesIf the unit’s MOCP device rating is 60-A or less, then theMOCP device is recognized as providing the requiredovercurrent protection to the heater and no internal fusingis required. If two heater modules are installed, a singlepoint box that contains only a field power terminal blockis required. If only one heater module is installed, no fuseor single point box is required. Connect field power leadsand heater power leads to the unit’s field connectionterminals in the main control box. See tables at thebeginning of Appendix A and B for where-usedinformation on the single point boxes and for connectionsFigure number.

Units with Factory Installed HACRThe amp rating of the HACR factory installed option isbased on the size, voltage, indoor motor and otherelectrical options of the unit as shipped from the factory.When field installed accessory electric heaters are addedor changed in the unit, the HACR may no longer be of theproper amp rating and therefore will need to be removedfrom the unit. See unit nameplate and label on factoryinstalled HACR for the amp rating of the HACR that wasshipped with the unit from the factory. See unitnameplates for the proper fuse, HACR or maximumover--current protection device required on the unit withfield installed electric heat.

TB10NOTE: TB10’s are not used on AC--1 size 16 and 180,HP--1 size 14 and 150, AC--2 size 14, and HP--2 size 12.

On larger 208/230-3-60 units, the MOCP rating for thebase cooling circuit exceeds 60-A. On these applications,the single point box kit contains two small single-poleterminal blocks that are installed in the main control box.Minor relocation of wiring results in separating the indoorfan motor load from the main power circuit, allowing thisload to be protected with a second fuse set. See singlepoint box kits CRSINGLE043A00, 045A00, 049A00,051A00, 053A00 and 054A00. (Units AC--1 size 14 and150 and HP--1 size 12 and 121, AC--2 size 12, HP--2 size09 use only one TB10 block to separate Compressor 2 andoutdoor fan motor loads from main unit circuit).

Single Point Box ContentsSee Package Content tables for a list of componentsincluded in each single point box kit. Note the heightdifferences and their use in specific size units.

Control WiringHeater modules contain one or two heater controlcontactors. If two heater modules are installed, or atwo-circuit heater module is installed, the cooling unit(AC type) can be connected for one-stage or two-stageheating control. On all heat pump units (HP type), allheater contactors will be connected to providesecond-stage heating control.

GENERAL INSTALLATIONSEQUENCE

1. Pre-stage heater packages and single point boxes byplacing the required component cartons at each unit.

2. Check the heater sales package number and singlepoint box part number (if used) against the partnumbers on the unit’s infoplate. See Fig. 1 and 2for typical data.

3. Install the SPB and connect power wiring tap con-ductors to field power terminals in main controlbox.

4. Install the electric heater module(s) and connectheater power conductors to single point box or mainunit control box per appropriate connections figure.(See Appendix A and B.) On AC--1 15 ton, AC--212--1/2 ton, HP--1 12--1/2 ton and HP--2 10 tonmodels with factory installed non--fused disconnectremove lead side factory wiring. Re--size wires perunit nameplate data with accessory electric heat.

5. Connect the heater control contactors to unit termin-al block TB4.

6. Mark the unit infoplate to indicate which heatermodule(s) have been installed.

7. Note the required wire size ampacity (WSA) for thefield power supply conductors. Select and installsuitable field power conductors from external safetydisconnect to unit power connection points, or con-firm wiring already provided is suitable for requiredWSA.

All Units Except HP--1 Size 14 and 150, HP--2Size 12,AC--1 Size 16 and 180, AC--2 Size 14The following text covers installation of single pointboxes and electric heaters in all units EXCEPT the HP-1size 14 and 150, HP--2 Size 12, AC--1 Size 16 and 180,AC--2 Size 14. For instructions on these units, skip topage 14.Check sales packages – Following the project drawingschedule tables or submittal documents, select thescheduled heaters and single point boxes (if used) andplace at each unit.Compare the sales package number(s) for scheduledheater modules against the approved usage table on theunit’s infoplate. See Fig. 1 and 2 for typical plate data. Ifthe scheduled heater usage does not appear on the unitinfoplate label, STOP. Contact the project engineer or thelocal distributor sales office for clarification.Open the cartons and inspect for damage.

Installing Single Point Box(CRSINGLE037A00--054A00)

8. Replace all access panels, posts and covers removedin Steps 3 and 8 on page 14 and 15. Place adhesive--backed Max. Air/Max. Static label on external panelthat covers heaters. (See Fig. 4, 4, and 42.)

NOTE: Supply wiring must comply with NEC (NationalElectric Code) and all local requirements.

9. Mark the appropriate block on the unit nameplatefor the accessory heater kW installed. Note the re-quired Minimum Circuit Ampacity (MCA) value forthis unit--heater combination. Ensure the fieldpower conductors are sized to handle this ampacity.Check also that the unit disconnect size and theovercurrent protection device for the branch circuitconductors are suitable for this unit--heater combin-ation.

10. Run conduit through (rigid or EMT) the conduitdrip boot in the rain shield bracket to the singlepoint box. Provide an appropriate fitting to connectthe conduit to the single point box wall and groundappropriately. (See Fig. 26.) Drip boot will acceptsizes ¾--in to 1--1/2 in. The drip boot eliminates theneed for watertight conduit fittings at the singlepoint box.

11. Run wire through conduit connecting outside powerto the designated terminals at the top of the singlepoint box. Ground appropriately. (See Fig. 28.)

12. If all other work on the unit is done, reapply powerper lock--out/tag out procedures.
