MCAC-RTSM-20-0 4. 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.

0Hz R40A ClimaMaster Tropical Rooftop Package Unit 4. Optional collocation MCAC-RTSM-20-0 4. 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

Attaching horizontal ductwork to unit ) All conditioned air ductwork should be insulated to minimize heating and cooling duct losses. Use a minimum of two (2) inches of insulation with a vapor barrier. The outside ductwork must be weatherproofed between the unit and the building. 2) When attaching ductwork to a horizontal unit, provide a flexible watertight connection to prevent noise transmission from the unit to the ducts. The flexible connection must be indoors and made out of heavy canvas. Note: Do not draw the canvas taut between the solid ducts. 2. Attaching down flow ductwork to roof curb Supply and return air flanges are provided on the roof curb for easy duct installation. All ductwork must be run and attached to the curb before the unit is set into place. Follow these guidelines for ductwork construction: ) Connections to the unit should be made with three-inch canvas connectors to minimize noise and vibration transmission. 2) Elbows with turning vanes or splitters are recommended to minimize air noise and resistance. ) The first elbow in the ductwork leaving the unit should be no closer than two feet from the unit, to minimize noise and resistance.
