5 GENERAL PuronR Units This installation instruction manual describes the installation of electric heaters and associated fuse block/field power termination kits (single point box or SPB) on small rooftop units in nominal cooling capacities from 3 to 2.5 tons (unit sizes 04 through 4). These rooftop units use Puron refrigerant (R-40A). See Package Usage tables on page 2 for applicable unit models. Unit types include cooling units (AC) and heat pumps (HP) distributed over several chassis sizes. Unit AC-, AC-2, HP-, HP-2 are identified. This information does not include selection data. Refer to project plans, job submittals and selection programs for heater and field power termination/spb kit usage. Some electric heaters used on these Puron (R-40A) units may also be installed in earlier R-22 rooftop units. Refer to Form 50-8SI or IIK for installation instructions on heater packages CR0A00 through 9A00 with earlier models. distributor office for a copy of this form. Electric Heaters Contact your local Heaters are shipped with one heater per carton. The carton is marked with a Sales Package Number. On all heaters except CR0A00 through 9A00, the heater Model Number (as marked on the heater infoplate) is the same as the Sales Package number. On CR0A00 through 9A00 heaters, the value in position 9 of the part number differs between the sales package part number (value is ) and bare heater model number (value is 0). (See Table.) The heaters are modular in design, with heater frames holding open coil resistance wires strung through ceramic insulators, limit switches and one or two control contactors. Power conductors are attached. One or two heater modules may be used in a unit. Heater modules are installed in the compartment below the indoor (supply) fan outlet. Access is through the indoor access panel. Heater modules slide into the compartment on tracks along the bottom of the heater opening. (See Fig. and 2.) Not all available heater modules may be used in every unit. Use only those heater modules that are UL listed for use in a specific size unit. Refer to the label on the unit cabinet for the list of approved heaters. (See Fig. and 2.) See Appendix C for electric heater module data. Single Point Boxes and Fuses The Single Point Box kits provide a field power termination location plus an enclosure for heater fuses when required by code. The SPBs are installed under the unit s main control box and include a hinged cover plus all internal wiring. Minimum components of the SPB are a field power terminal block with tap conductors (to connect to the unit s main control box field terminals). Maximum component population includes up to five fuse blocks. Fuses for electric heater circuits are required and provided when the unit s MOCP exceeds 60-A or when the total heater Full Load Amp value exceeds 48-A. When fuses are required and provided, the cooling circuit is also provided with fuse protection; some units require minor wiring changes in the main control box (see section on TB0 terminal blocks). No Fuses If the unit s MOCP device rating is 60-A or less, then the MOCP device is recognized as providing the required overcurrent protection to the heater and no internal fusing is required. If two heater modules are installed, a single point box that contains only a field power terminal block is required. If only one heater module is installed, no fuse or single point box is required. Connect field power leads and heater power leads to the unit s field connection terminals in the main control box. See tables at the beginning of Appendix A and B for where-used information on the single point boxes and for connections Figure number. 5

8 TB0 On larger 208/ units, the MOCP rating for the base cooling circuit exceeds 60-A. On these applications, the single point box kit contains two small single-pole terminal blocks that are installed in the main control box. Minor relocation of wiring results in separating the indoor fan motor load from the main power circuit, allowing this load to be protected with a second fuse set. See single point box kits CRSINGLE043A00, 045A00, 049A00, 05A00, 053A00 and 054A00. (Units AC- size 4 and HP- size 2 use only one TB0 block to separate Compressor 2 and outdoor fan motor loads from main unit circuit). Single Point Box Contents See Package Content tables for a list of components included in each single point box kit. Note the height differences and their use in specific size units. Control Wiring Heater modules contain one or two heater control contactors. If two heater modules are installed, or a two-circuit heater module is installed, the cooling unit (AC type) can be connected for one-stage or two-stage heating control. On all heat pump units (HP type), all heater contactors will be connected to provide second-stage heating control. GENERAL INSTALLATION SEQUENCE. Pre-stage heater packages and single point boxes by placing the required component cartons at each unit. 2.
