Anleitung Zusammenfassung
WARNING signifies hazards which could result in personal injury or death. CAUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage. 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 with a suitable warning label. Electrical shock can cause personal injury or death. INSTALLATION Step 1—Check Equipment and Jobsite UNPACK UNIT — Move to final location. Remove carton taking care not to damage unit. INSPECT EQUIPMENT — File claim with shipping company prior to installation if shipment is damaged or incomplete. Locate unit rating label on unit service panel. (See Fig. 2.) It contains information needed to properly install unit. Check rating label to be sure unit matches job specifications. Step 2—Install on a Solid, Level Mounting Pad If conditions or local codes require the unit be attached to pad, tiedown bolts should be used and fastened through knockouts provided in unit base pan. Refer to unit mounting pattern in Fig. 2 to determine base pan size and knockout hole location. When installing, allow sufficient space for airflow clearance, wiring, refrigerant piping, and service. Allow 30-in. (762mm) clearance to service end of unit and 48 in. (1219mm) above unit. A94356 Fig. 1—Model 38CKB For proper airflow, a 6-in. (152mm) clearance on 1 side of unit and 12 in. (305mm) on all remaining sides must be maintained. Maintain a distance of 24 in. (610mm) between air conditioners. Position so water, snow, or ice from roof or eaves cannot fall directly on unit. On rooftop applications, locate unit 6 in. (152mm) above roof surface. Where possible, place unit above a load-bearing wall. Arrange supporting members to adequately support unit and minimize transmission of vibration to building. Consult local codes governing rooftop applications. Step 3—Replace Indoor AccuRater® Piston, if Required Check indoor coil piston to see if it matches the required piston shown on unit rating label. If it does not match, replace indoor coil piston with piston shipped with this unit. The piston shipped with outdoor unit is correct for any approved indoor coil combination. Remove indoor coil piston if unit is to be installed on system with a TXV metering device. Step 4—Make Piping Connections Outdoor units may be connected to indoor sections using accessory tubing package or field-supplied refrigerant grade tubing of correct size and condition. For tubing requirements beyond 50 ft (15.24m), consult Long-Line Application Guideline which is available at your local distributor. NOTE: In some cases, noise in the living area has been traced to gas pulsations from improper installation of equipment. INSTALLATION RECOMMENDATIONS 1. Locate the unit away from windows. 2. Ensure that vapor and liquid tube diameters are appropriate to the capacity of the unit. (See Table 1.) Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations. Book 4 PC 101 Catalog No. 013-862 Printed in U.S.A.

Run refrigerant tubes as directly as possible by avoiding unnecessary turns and bends. 4. Leave some slack between the structure and the unit to absorb vibration. 5. When passing refrigerant tubes through the wall, seal the opening with RTV or other pliable silicon-based caulk. (See Fig. 3.) 6. Avoid direct lineset contact with water pipes, ductwork, 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 the tubing. (See Fig. 3.) 8. Ensure that tubing insulation is pliable and completely surrounds the vapor tube. 9. When necessary, use hangar straps which are...
