1 Rev A (5/00) TECHNICAL GUIDE 16 SEER 2-5 TON CONDITIONING SPLIT-SYSTEM COOLING DESCRIPTION The HTS Stealth series condensing units use Twin Single compressor technology to provide cooling efficiencies up to 16.7 SEER. They are to be installed with the matching variable speed Enhancer air handler or Diamond furnace, or with a two-stage or single-stage indoor unit, a corresponding coil and sweat connect lines. A factory specified balanced port hard shut-off TXV kit must be used for proper installation and optimum performance. These units are backed by a 10 - year limited warranty on the compressor and 1 - year on all other parts. FEATURES QUALITY CONDENSER COILS - The coil is constructed of copper tube and hardened aluminum fins for durability and long lasting efficient operation. The fins on the unit are protected with a decorative grille. DURABLE FINISH - Cabinet is made of powder painted steel over prepainted primer. The pre-treated flat galvanized steel provides a better paint to steel bond, which resists corrosion and rust creep. Special primer formulas and glossy earth tone finish insure less fading when exposed to sunlight. This finish has been tested to provide 1/3 greater protection than conventional units. PROTECTED COMPRESSORS - The Twin Single compressor is protected against high and low pressure. Hard start components are included to ensure start-up under adverse conditions. All models have standard crankcase heat for added protection. OPTIMUM PERFORMANCE - The solid-state electronic controlboard optimizes the compressor staging based on load requirements, provides a 5-minute anti-short cycle timer for each compressor, and simplifies troubleshooting with built in self diagnostics. LOWER INSTALLED COST - Installation time and costs are reduced by easy power and control wiring connections. All units contain enough refrigerant for the smallest matching indoor coil and 15 feet of interconnecting piping. The small base dimension means less space is required on the ground or roof. EFFECTIVE HUMIDITY CONTROL - The inherent design of the Stealth system and the staging operation of the Twin Single compressor provide effective humidity control at the lowest possible operating cost. An optional dehumidification control accessory is available to maintain the humidity at a set desired level. TOP DISCHARGE - The warm air from the top mounted fan is blown up away from the structure and any landscaping. This allows compact location on multi-unit applications. LOW OPERATING SOUND LEVEL - The upward air flow carries the normal operating noise up away from the living area. The rigid top panel effectively isolates any motor sound. Isolator mounted compressor and the rippled fins of the condenser coil muffle the normal fan motor and compressor operating sounds. MODELS: H4TS024 H4TS030 H4TS036 H4TS048 H4TS060 LOW MAINTENANCE - Long life permanently lubricated motor- bearings need no annual servicing. EASY SERVICE ACCESS - Fully exposed refrigerant connections and a single panel covering the electrical controls make servicing easy. Easy access for coil clearing is also provided. RE-USABLE SERVICE VALVES - Provided on both the liquid and vapor sweat connections for ease of evacuating and charging. FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE
