OPTIONAL ITEMS A. MIXING BOX The optional mixing box has front return air arrangement with fresh air opening is always from the side of the unit and is fixed on the same unit for (BMY020 - BMY070) while it will be shipped separately for (BMY080 - BMY095). Additional accessories such as return and fresh air dampers (oppose blade) and rain hood can be provide. B. ECONOMIZER/CO2 MONITORING The economizer permits low-cost operation by utilizing cool outdoor air for free cooling. A damper on the economizer controls the amount of outdoor air and on closed position it provides a leak proof seal. It can easily be adjusted for 100% outdoor air, 100% return air or any proportions of mixed air. The Economizer is operative either by a dry bulb Outdoor Air Thermostat (OAT) or a Solid State Enthalpy Controller (EC) to sense the outdoor air temperature. The unit is equipped with an electronic control board, the economizer controller with a sensitive feedback system carefully modulating the damper to allow correct percentage of fresh air and return air. The economizer controller is designed to match with Zamil electronic thermostat. 4

7 1. OUTDOOR AIR THERMOSTAT (OAT) ECONOMIZER CONTROL Economizer operation is governed by outdoor temperature and unit OAT setting, as follows: a. Outdoor Temperature > Outdoor Air Thermostat (OAT) setting: (High ambient) If the thermostat calls for cooling, the economizer damper moves to minimum position, simultaneously blower motor, compressor-1 & fan motors would start. If further cooling is required, compressor-2 also starts with a time delay. After the thermostat is satisfied the compressors are staged out. The economizer controller moves the damper automatically to closed position simultaneously the blower is also shutdown. b. Outdoor Temperature < Outdoor Air Thermostat (OAT) setting: (Low ambient) As the cooling load would be low, the economizer controller will operate as stage-1 of cooling system first switching ON the blower motor simultaneously modulating the damper in steps to required position, allowing the cool outside air into indoor side. If further cooling is required compressor-1 & fan motors will switch ON as stage-2 of the system, whereas compressor-2 is pulled out of service. As the room temperature is attained, economizer controls will cut-off the compressor, fan motors simultaneously closing damper to fully closed position. 2. ENTHALPY SENSOR FOR ECONOMIZER CONTROL The solid state enthalpy sensor is capable of accurately sensing outdoor air enthalpy content (temperature & humidity) and controlling the economizer damper for the minimum heat content introduce to the evaporator coil. Thereby, providing an efficient & economical system operation. 3. CO2 MONITOR Indoor air quality (IAQ) is becoming more and more important, CO2 monitoring give an indication of the amount of CO2 inside a facility. Once it is exceeding a certain level it sends a signal to the control system demanding for fresh air to replace the inside poor quality air. The control is responding in opening the damper and at the same time there is input in the control for an exhaust relief fan externally connected to the unit as it purge the poor quality air. ECONOMIZER SYSTEM WITH CO2 MONITOR C. ULTRA VIOLET LIGHT FOR IMPROVED INDOOR AIR QUALITY Why use "UV FLOW TM " solution for IAQ: 1. Improved Overall Indoor Air Quality When used for general IAQ control, UV FLOW TM products can successfully: Control fungi in HVAC systems to reduce or eliminate mold-related allergies. Prevent the development of different types of bacteria. Reduce the spread of cold and flu viruses and other airborne-transmitted diseases. Eliminate odors and maintain a fresh air smell indoors. UV FLOW TM Emitters pose no risk to components, equipment or inhabitants. Their non-chemical energy kills organisms without producing secondary contamination and costs little to operate. 5

8 2. Save Energy and Cut Costs UV FLOW TM can reduce maintenance cost as UVC lights successfully eliminate the bio-film (dirt) that fouls surface of heat exchangers - completely cleaning and continuously maintaining coils and drain pans to 'as new' conditions. This in turn improves heat-transfer efficiency, coil pressure drop, and fan performance. D. ELECTRIC HEATERS Electric heaters are of the resistance open coil type and conform to the requirements of UL 573 or equivalent. Electrical characteristics, capacities and number of stages are as indicated. Thermal cut-outs, fusible links and airflow switches are provided to shut-off power to heaters in case of airflow failure. E. ELECTRONIC THERMOSTAT General information: Electronic thermostat shall control one or two stage heating and cooling applications. The thermostat normally displays room temperature and mode of operation. The temperature can be set by up/down buttons for both cooling and heating cycles. The thermostat also allows you to select continuous fan operation, or have the fan on intermittent operation with the equipment. The thermostat is best located about 1500 mm (5 Ft.) above floor level, on a partition wall (not an outside wall), and should not be exposed to direct light from lamps, sun etc. It should be in return air stream, away from supply air registers/diffusers.

11 SELECTION PROCEDURE 1. Determine cooling and heating capacity requirements at design conditions Data: Condenser entering air temperature : F Evaporator entering air temperature : 80 0 F DB / 67 0 F WB Evaporator airflow : 14,000 CFM Required cooling capacity : 420,000 BTUH Sensible heat capacity : 300,000 BTUH Required heating capacity : 40 External static pressure : 1.6 INCH WG. Power supply (V-Ph-Hz) : Unit type : Front fan supply (front return air) 2. Unit selection based on required cooling capacity Enter cooling capacity performance data at condenser entering air temp. at F and evaporator entering air temp F DB, 67 0 F WB, CFM airflow. The BMY040 with CDX040 (matching condensing unit) will give 474,000 BTUH cooling capacity (gross) and 354,000 BTUH sensible heat capacity (gross). 3. Electric heater selection Heating capacity required = 40. Enter electric heating table for BMY040 at power supply. 40 heater at 460 volts satisfies the required heating. 4. Determine fan speed and power requirements at design conditions Before entering the fan performance tables, calculate the summation of external static pressure for the required components as follows. External static pressure Additional module : 1.6 INCH WG. : NIL 1.6 INCH WG. Enter fan performance table for BMY040 model. For CFM and external static pressure of 1.6 INCH WG, it require 1006 RPM and brake horse power (BHP) wherein the standard motor will meet job requirements. 5. Determine input power to motor Use fan motor efficiency table. Blower motor watts = BHP x 746 watts x 746 = Motor efficiency 0.91 = 10,042 watts. 6. Determine net capacities Above capacities are gross and do not include blower motor heat gain. Determine net capacities as follows: Net cooling capacity = Gross cooling capacity blower motor heat = 474,000 (10,042 WATTS x BTUH/WATTS) = 439,727 BTUH Net sensible capacity = 354,000 (10,042 WATTS x BTUH/WATTS) = 319,727 BTUH 7.To calculate leaving air conditions (see footnote for capacity tables) DBL = DBE (Sensible Capacity (Btuh) / 1.08 x CFM) WBL = DBL [DR (DBE WBE)] WBL WBE When sensible capacity approaches 1.0, especially at entering DB higher than 80 0 F, find DBL in the same manner above, but WBL is to be found from intersection of DBL Line on a psychrometric chart with the horizontal line of humidity ratio (W) where (at SHR = 1), WL = WE.

52 A. GENERAL INSTALLATION INSTRUCTIONS Blower units are shipped completely wired. Only external power, interconnecting control wiring between outdoor and indoor units and refrigerant pipe connections are needed to complete the installation. B. UNIT LOCATION & ACCESS SPACE The placement of the unit in relationship to the building is very important. Refer page 49 for service clearances. When making tubing connections, be sure to provide clearance for electrical connections. C. TUBING INSTALLATION Do not remove plugs from the compression fittings until tubing has been run and is ready for connection. a. Make sure the tubing is round, without dent or burrs. b. Cut tubing to the length required with a tube cutter carefully. Do not use a hacksaw. c. Remove burr from inside and outside using file or deburring tool. NOTE: Always use a gear type tube bender when making bends in suction line. When installing tubing through walls or along side of any structural members, be sure the tubing is isolated from these members or walls to avoid any transmission of vibration that may occur, while unit is running. ELECTRICAL STEP 1: INSTALLATION A) Please ensure power supply to the unit is as per unit nameplate (Volts/Ph/Hz) requirements. Caution: Operation of the unit on improper power supply will result in damage to the unit. NOTE: Use copper wires of proper rating for all field wiring. Warning Before servicing or installation of the unit, always TURN OFF all power to the unit. There may be more than one disconnect switch. Ensure all of them are turned off. Electrical shock can cause personal injury or death. B) Ground & power wires Connect power wires to terminal block per wiring diagram. Connect ground wire to the ground lug inside the control box. C) Control wiring between outdoor & indoor unit Use 16 gauge color-coded wire between the indoor and outdoor units (control wiring). STEP 2: START-UP Refer to outdoor unit installation instructions for system start-up instructions and refrigerant charging method details. STEP 3: SEQUENCE OF OPERATION With power supplied to indoor and outdoor units, the unit starts responding to the thermostat mode requirement. Cooling mode: When thermostat calls for cooling, the blower motor in the indoor unit is switched on. The compressor contactor is energized to start the compressor and condenser fan. As the conditioned space approaches the thermostat cooling set point, the unit cycles off. Heating mode: When thermostat calls for heating, the blower motor in the indoor unit is switched on. The contactor for electric heater is switched on to energize the heaters. If the room temperature is not satisfied and there are two heaters installed, the second heater also will be energized. Once, the conditioned space approaches the desired temperature set point, the heating stages cycles off. Fan mode: In this mode the indoor unit blower motor is switched on alone. 50
