WARNING: Before installing, modifying, or servicing system, main electrical disconnect switch must be in the OFF position. There may be more than 1 disconnect switch. Lock out and tag switch(es) with a suitable warning label. Electrical shock can cause personal injury or death. INSTALLATION RECOMMENDATIONS NOTE: In some cases noise in the living area has been traced to gas pulsations from improper installation of equipment. 1. Locate unit away from windows, patios, decks, etc. where unit operation sounds may disturb customer. 2. Ensure that vapor and liquid tube diameters are appropriate to capacity of unit. 3. Run refrigerant tubes as directly as possible by avoiding unnecessary turns and bends. 4. Leave some slack between structure and unit to absorb vibration. 5. When passing refrigerant tubes through the wall, seal opening with RTV or other pliable silicon-based caulk. (See Fig. 3.) Cancels: II 661C-18-6 II 661C-18-7 A94355 Fig. 1—Models 661C Fig. 2—Models 661G and 661S A98524 6. Avoid direct tubing contact with water pipes, duct work, floor joists, wall studs, floors, and walls. 7. Do not suspend refrigerant tubing from joists and studs with a rigid wire or strap which comes in direct contact with tubing. (See Fig. 3.) 8. Ensure that tubing insulation is pliable and completely surrounds vapor tube. 9. When necessary, use hanger straps which are 1 in. wide and conform to shape of tubing insulation. (See Fig. 3.) 10. Isolate hanger straps from insulation by using metal sleeves bent to conform to shape of insulation. —1— NOTE: Avoid contact between tubing and structure INSULATION OUTDOOR WALL INDOOR WALL INSULATION CAULK THROUGH THE WALL HANGER STRAP (AROUND VAPOR TUBE ONLY) JOIST 1. MIN. SUSPENSION LIQUID TUBE VAPOR TUBE VAPOR TUBE LIQUID TUBE A94208 Fig. 3—Connecting Tube Installation When outdoor unit is connected to factory-approved indoor unit, outdoor unit contains system refrigerant charge for operation with indoor unit of the same size when connected by 15 ft of field-supplied or factory accessory tubing. For proper unit operation, check refrigerant charge using charging information located on control box cover. IMPORTANT: Maximum liquid-line size is 3/8-in. O.D. for all residential applications including long line. IMPORTANT: Always install a liquid-line filter drier. Refer to Product Data Sheet for appropriate part number. Obtain filter drier from service parts or your distributor or branch. INSTALLATION I. CHECK EQUIPMENT AND JOB SITE A. Unpack Unit Move to final location. Remove carton taking care not to damage unit. B. Inspect Equipment File claim with shipping company prior to installation if shipment is damaged or incomplete. Locate unit rating plate on unit service panel. It contains information needed to properly install unit. Check rating plate to be sure unit matches job specifications. II. INSTALL ON A SOLID, LEVEL MOUNTING PAD If conditions or local codes require the unit be attached to pad, tie down bolts should be used and fastened through knockouts provided in unit base pan. Refer to unit mounting pattern in Fig. 4 to determine base pan size and knockout hole location. On rooftop applications, mount on level platform or frame 6 in. above roof surface. Place unit above a load-bearing wall and isolate unit and tubing set from structure. Arrange supporting members to adequately support unit and minimize transmission of vibration to building. Consult local codes governing rooftop applications. Roof mounted units exposed to winds above 5 mph may require wind baffles to achieve adequate defrost. Consult Low-Ambient Guideline for wind baffle construction. A94199 C B A 3.8.D. (9.53) TIEDOWN KNOCKOUTS (2) PLACES DIMENSIONS (IN.)

III. CLEARANCE REQUIREMENTS When installing, allow sufficient space for airflow clearance, wiring, refrigerant piping, and service. Allow 30-in. clearance to service end of unit and 48 in. above unit. For proper airflow, a 6-in. clearance on 1 side of unit and 12 in. on all remaining sides must be maintained. Maintain a distance of 24 in. between units. Position so water, snow, or ice from roof or eaves cannot fall directly on unit. On rooftop applications, locate unit at least 6 in. above roof surface. IV. OPERATING AMBIENTS The minimum outdoor operating ambient in cooling mode is 55°F, and the maximum outdoor operating ambient in cooling mode is 125°F. The maximum outdoor operating ambient in heating mode is 66°F. V. ELEVATE UNIT CAUTION: Accumulation of water and ice in base pan may cause equipment damage. In areas where prolonged freezing temperatures are encountered, elevate unit per local climate and code requirements to provide clearance above estimated snowfall level and ensure adequ...
