freezing and damage. One 5/8" O.D. copper trap & plastic tubes (3) (furnished) / Pan No. 307g0F089 Date 6-1_9 Supemedes 30790G082 Page T of 12 INSTALLATION Electrical Connections All wiring to unit must comply with the national Electrical Code NFPA No. 70 or local codes, where they prevail. ANY ALTERNATION OF INTERNAL WIRING CAN VOID UNDERWRITER'S APPROVAL, ARI CER TIFICATION AND MANUFACTURE'S LIMITED WARRANTY. The series and rating plates indicate the operating voltages, phase, ampacities and maximum fuse size and electric heater ratings. Units must never be installed where voltage exceeds 110% of higher voltage indicated on rating plate, or less than the minimum operating voltage on rating plate, Ratings and BTU output are based on 230 V, 60 HZ supply. Voltages other than this rated voltage will alter the BTU output of this unit. For specific ratings at voltages or frequencies other than that designated contact your distributor or the manufacture. FAILURE OF THE COMPRESSOR AS A RESULT OF OPERATION ON IMPROPER VOLTAGE VOIDS THE COMPRESSOR REPLACEMENT WARRANTY. Multiple power supply connections must be used when total unit amp draw Is over 48 amps. If multiple power supply connections are used, separate fused disconnects must be Installed for each circuit between the main panel and the supply terminals In the unit. Circuit No. 1, terminals L1 and L2 on the terminal block Is always used to supply power to the heat pump section. See Figure 3, 4, and 5. Circuit No. 2, terminals L3 and L4 on terminal block (units up to 11.0 KW) or fuse block (units over 11.0 is always used to supply power to electdc heaters. Single entry supply may be used on units, when total amp draw, (heat pump plus heaters) Is less then 48 amps, and is not In violation of prevailing electrical codes. Units with 7.2 KW heaters or less are supplied with Internal jumpers between 1.1& 1.3, and L2 & L4 for single entry supply. Remove jumpers between L1 & I..3 and 1.2 & L4 when multiple entry supply is to be used. Fuse and wire sizing must be in accordance with prevailing electrical codes. See Product Specification sheets or Unit Sedes and Rating Plate for ampacities end maximum fuse.

See product specification sheets or label on unit for manufacture's part number. Install the thermostat according to directions furnished with It. Select a location in a room having the most wall or window area exposed to the outsid_ Locate on an inside wall, away from drafts, sunlight or any heat producing appliances. Connect thermostat wires to pigtail leads on unit with wire nuts following wire diagrams attached to unit. Air Filter This unit is supplied with a permanent type high filtration filter, located in front of the indoor coil. If an Intallation is made in which it Is more desirable to mount the filter extedor to the unit In the return duct, the permanent filter supplied can be used or a disposable filter may be used. If a different filter or filters are used the minimum total filter area required is 375 eq. in. of nominal 112inch thick media, if a remote filter is Installed, the permanent filter supplied with this unit must be removed. Duct Work Provide duct work sufficiently large enough to handle the air volume at the total external static pressure not exceeding the rating of the unit published in the Product Specification sheet for the rated cooling air volume. Connect supply duct to top of unit using canvas connections or other flexible connection to prevent sound transmission Into the duct system. To connect the return duct to the unit, use e straight piece of duct 21 _" by 9". Insert duct into return opening in bottom of unit and flange duct over existing flanges around opening Inside unit. Make sure that all sides of the duct are flanged over to permit removal of cooling chassis If required. Use a flexible connection to attach remainder of return air duct. Adjustments No adjustments are required or should be attempted regarding any of the components of the heat pump chassis and supplementary electdc heaters. The unit should be checked to see that none of the wiring is loose or missing. The plug-in electrical connec. tors between the cooling chassis and the main contro...
