Before installation, it is recommended to check the correction factor table (table ) below in order to do a correct design selection. Noted that it has different factor used for different selection of fresh air opening, in both cool mode and heat mode. Table : Correction factor for unit's performance.

Before installation, it is recommended to check the pressure drop in table 2 below in order to do a correct design selection. Table 2: Pressure drop in economiser kit Rooftop Model Economiser Kit Model Standard Airfow Rate Cfm m/s 0% Outdoor Air Damper Opening (Pa) 5% Outdoor Air Damper Opening (Pa) Pressure drop in economiser kit from table 2 refers to initial resistance. An air filter that is installed in the rain hood of economiser will expose to outdoor environment and easily becomes dirty. Regular service is required for this filter (recommended at least once every two weeks). The final resistance shall not exceed the recommended value in table below. Table : Technical specifications for air filter in economiser rain hood. Note: * Initial resistance is rated based on 85% of outdoor air opening.

Table provides guidelines only on the service of filter. Thus, system sizing does not require to include these values into consideration. Optional Air Filter There is a 2" filter slot inside the unit. Optional filter (field supplied) is recommended as the second layer filtration since outdoor air damper opening may bring in dust and dirt. In order to ensure that final resistance of the filter not exceed recommended values, service the filter every 2 weeks or more frequent if necessary. Limitation Of Economiser Kit In Thermostat Control Thermostat control is used with third party controller and thus the setting temperature of specific application cannot be known. For this case, it is recommended to use remote controller to set the required setting temperature before the hardware setting for thermostat control is conducted. The minimum fresh air opening for fan mode in thermostat control operation shall follow the user's selection in hardware setting (Dip Switch and Dip Switch 2), whichever is lower. Note: Refer to hardware setting guideline provided in part (v) under chapter 'control operation guide' in installation manual for mode selection. Necessary For Pressure Relief Presence of fresh air may cause building pressure rises and bring discomfort to the users. When necessary, it is recommended to install a relief damper or exhaust fan in the return air duct. The relief damper may be a gravity type or motorized type. It is used to maintain building pressurization by regulating the flow of relief air from the building. For most bulding, the maximum pressure is not to exceed 25Pa. 22 Rooftops Single Unit

From the blower curve, select the point that can meet both of the requirements (ESP = 200Pa and airflow rate = 00cfm). Step 2: Read RPM value from the blower curve. Next, refer to the RPM value in the blower curve which is corresponding to this point. For instance, from the blower curve on the right, RPM which is corresponding to this point = 727. Step : Read power consumption value for indoor fan motor. Then, use this RPM value to estimate the power consumption of indoor fan motor by referring to the table of Motor Variable Pitch Pulley Data. For instance, from the table, indoor fan motor with 727RPM consumes 000W. Total static pressure (Pa) Standard Point Internal Static Pressure Step 4: Read number of turns for variable pitch pulley. Similarly, use this RPM value to read the no. of turns (N) by referring to the table of Motor Variable Pitch Pulley Data. The variable pitch pulley for motor shall be adjusted to this N in order to achieve the desired point (ESP = 200Pa and airflow rate = 00cfm). Air Flow Note: The shaded area indicates the operating range of variable pitch pulley which is used with standard motor (factory fitted). In case if the operation is out of range, change pulley or/and motor size. For instance, from the table, no. of turns (N) =.5 in order to get 727RPM. First, adjust the motor pulley to 0 turns. Then, makes and half turns on the pulley. Cross check the dimension X, which stands for regulation space of motor pulley. In this case, X =.5mm. CFM L/S Rooftops Single Unit 4
