4 MCAC-RTSM Feature & Benefit 0Hz R40A ClimaMaster Tropical Rooftop Package Unit. The adoption of anticorrosive-box The reinforced anticorrosion by using galvanization armor plate and coated with man-composed paint. The appearance is stylish and be easy for maintenance. (It s OK for 000 hours salt spray test) 2. The adoption of credible protection system 2. The protection for compressor High-pressure protection, low-pressure protection, compressor current protection and so on the series protectors can ensure compressor operating normally. Adopts independent system, except for protections of sequence and wire control output, any protection relate to its corresponding compressor. Once a compressor protection energized, the corresponding compressor will stop, others are still working. 2.2 Fan motor The fan motors for evaporator have over-heat protection and over-current protection function. The fan motors for condenser have the temperature controller protection function.. Energy saving design. High efficiency compressor Using technical compressor, heat exchanger and optimum connection pipe, the compressor can startup under low power input. Provide maximum reliability, efficiency and quiet operation. Two refrigerant circuits on larger units (above 2.ton) provide efficient part load performance. Standard low and high pressure safety switches. Nice compressor control Compressor staging is controlled directly by the indoor temperature. When the indoor temperature is warmer than the setting, cooling is staged up; when the indoor temperature is cooler than the setting, cooling is staged down. However, a stage change can only occur when the indoor temperature is outside the dead band. Staging is constrained by an inter-stage delay timer. These constraints protect the compressors from short cycling while eliminating temperature variations near the diffusers..2 Condenser By using high-efficient thin fin, the condenser has high-efficient heat exchanger, the energy waste decreases greatly.. Evaporator By using the high-efficient, super thin fin and inner-whorl copper pipe, the evaporators get the higher capacity and the lower noise level..4 The heat insulation of indoor unit The heat insulation of indoor unit can availably decrease heat loss.. The control and refrigerant cycle system There are two independent control systems and refrigerant cycle system, the capacity output is adjusted automatically depending on different demand, save energy when one control system is in running according to low capacity output.

5 0Hz R40A ClimaMaster Tropical Rooftop Package Unit 4. Optional collocation MCAC-RTSM Operation in high temperature The air-conditioner designed for high temperature can run until the ambient temperature reaches up to 2 (2 ). 4.2 Strong air flow Large air volume from the air inlet is forced ventilating by the condenser fan. 4. Minimum installation arrangement The installation is fast and low cost with the easy installation and ready operation. 4.4 Pre-drilled duct flange Flanges are prepared at the supply and return duct connections so that they can reduce duct connection work at site. Flange 4. Quiet operation Noise and vibration have been effectively reduced by adopting new style hermetic compressor. The centrifugal fan and fan casing are optimum shaped for efficient and low noise operation.. Cabinet. Sloped drain pan and drain pipe..2 Cabinets have forklift and lifting holes for easy transportation.. Cabinets have fresh air function, and the filter can be washable. Fresh air inlet (except for ton).4 External pressure gauge port. The external pressure gauge port, which is identified permanently and clearly the embossed wording, H is high pressure connection and L is low pressure connection. With the gauge port mounted externally, an accurate diagnostic for system operation can be quick and easy without disrupting airflow.. Durable construction. Weather-resistant construction with capped seams and sloped top panels.g90 galvanized heavy gauge plate conforming to ASTM-A-, Zinc content of galvanized plate is 27 g/m 2. 4

Optional supply/return airflow design, from side or bottom, It could be flexibly applied to multi-position. The rooftop or ground installation is optional. 7. Certification of the compressor The compressors have CE certified, UL certified.

7 0Hz R40A ClimaMaster Tropical Rooftop Package Unit. List of Function MCAC-RTSM Standard specification A. General The Packaged cooling or combination heating and cooling unit is suitable for mounting on the roof or ground. The packaged unit consists of scroll compressors, evaporator coil, condenser coil, control wiring and interconnecting piping- all factories assembled and mounted on heavy gauge G-90 galvanized steel sheet press formed base, ready for field connection to utilities and ducts. The packaged unit is of rigid construction with holes provided in the base rails for overhead rigging. The unit is provided with an integral weather resistant control panel. These units are rated and tested in accordance with ARI standard 20/ARI 0. B. Unit enclosure Panels are of heavy gauge, G-90 galvanized steel sheet with removable access panels, completely weatherized for outdoor installation and properly reinforced and brazed. Panels and access door are provided for inspection and access for all internal parts. Enclosures are provided with adequately reinforced points of support for setting in the unit. Steel sheet panels are zinc-coated and galvanized by the hot dip process of lock forming quality conforming to ASTM A commercial weight G-90, followed by baked on electrostatic polyester dry powder coat paint, on all external panel. C. Compressor Compressors are scroll for all the models. They are provided with all the standard controls and accessories necessary for safe operation. These are equipped with internal motor protector; factory installed crank case heater and rubber vibration isolator for quiet and efficient operation. D. Air-cooled condensing section. The air-cooled condensing section is enclosed within the unit housing and consists of condenser coil, fan(s) electric motor(s) and inherently protected compressor(s). As an option, enhanced coated aluminum fins may be provided. Tube support sheets are galvanized steel, formed to provide structural strength. 2. Fans are propeller type, direct driven, upward discharge and provided with fan grille mounted on the casing.. Motors are totally enclosed air-over type with class F insulation. Inherent thermal protection is automatic reset type. E. Evaporator coil section. All cooling coils are of enhanced louvered fins and inner grooved copper tubes with wall thickness of 0.mm, mechanically bonded to aluminum fins. Return bend has 0.0 inch thickness (0.mm).

Before lift, please check and ensure that hooks are holding tightly to unit and lifting angles are no less than 0. Cloth material or hard-paper should be padded in the contact place between unit and rigging cable. Rigging cable should be entwined a round at the hook to forbid danger because of weight unbalance. During lifting, anyone forbidden lingering under the lifting unit. 4.2 Service Space. The recommended clearances for single-unit installations are illustrated in following Fig. These minimum requirements are not only an important consideration when determining unit placement, but they are also essential to ensure adequate serviceability, maximum capacity, and peak operating efficiency. 2. Any reduction of the unit clearances indicated in these illustrations may result in condenser coil starvation or the recirculation of warm condenser air. Actual clearances which appear to be inadequate should be reviewed with a local engineer. For.2ton and above
