No evaluation of the roof or building structure was performed. The curb was evaluated using worst case seismic and wind loads from California and Florida. • Seismic Design • Wind Design: o Sos = 1.33 o Risk Category: II, III or IV o Max Unit Weight: 2000 lbs o Exposure Class C o Rp= 2 o Mean roof height: 60ft. o Ap = 2.5 o Wind Speed: 185 MPH Loads experienced by each curb and unit were calculated. The loads were used to design the unit to curb and curb to roof connections. The loads were also used to evaluate if the curb is adequate carry the unit and restrain the whole assembly to the roof structure. The unit to curb connection is made with #14 TEK screws passing through the lower lip of the curb and into the upper lip/flange of the curb. CalDyn JQ model isolators are used to isolate the forces generated by the unit into stiffened sections of the curb. The adequate CalDyn isolator was selected and the adequacy of the curb stiffener section was evaluated. This analysis was performed for a maximum unit weight of 2000 lbs, thus the total weight of the main unit plus any additions is to be equal to or less than 2000 lbs. If the unit weight is higher than this, further calculations will need to be performed. The unit shall be held onto the curb using (13) #14 TEK screws along each long edge of the curb section and (9) along each short edge for a total of (44). This curb requires Caldyn Model JQA isolators or better at all isolation support locations (12 total). A 14 gauge 1.5x6 channel supports the area immediately under each isolator. All channel supports were found to be adequate to resists compression failure and buckling due to isolator loads. All curb flanges were found to be adequate in bearing and bending. The anchorage to the roof was designed using CDI details from the drawing titled "SEISMIC-CURB- ATTACHMENTS" dated 7/24/2017 by spickar. The bearing of the bolts on the curb flange was evaluated considering the 12-gauge steel and .25" to .625" diameter bolts. All fasteners on the flange of the curb must be installed no more than 0.5" away from the inside edge of the flange. Screws should first be installed one on either side of each isolation support with the remainder spaced evenly. For a steel roof connection (6) '/a" 0 A307 bolts or equivalent are required along each long edge of the curb Filename: 18-001T LTRO1 1 26 2018 Page 1 of 2 VAK MEMO 12/11/2018 and (2) along each short edge of the curb for a total of (16). For a wood roof connection A" 0 SDS wood screws or equivalent are required, (15) along each long edge of the curb and (13) along each short edge for a total of (56) screws. For a concrete roof connection 5/8"0 Simpson Strong Bolts are to be used (6) are required along each long edge of the curb and (2) along each short edge for a total of(16) bolts.

Condenser fans with ECM motors shall be provided as well as factory sensors to provide this protection. • Compressor Envelope Control: The unit controller will continually monitor the suction and discharge pressure and temperature conditions during compressor operation. The unit will modulate the compressor, condenser head pressure,and electronic expansion valve to maintain a safe compressor operating conditions to add reliability,and limit unit shut down during fringe operating conditions. o CHANGE OVER SETPOINTS: The unit change over source temperature is the variable, Outdoor air temperature (OAT), Return air temperature(RAT),or space temperature(ST),that drives the change of unit states. The unit state will change from cooling,fan only or heating based on the changeover heating or cooling setpoints. o SUPPLY FAN:The RTU will be factory supplied with a direct drive supply fan. • VAV Duct Pressure: The supply fan will operate continuously. The unit will modulate the supply fan as required to maintain the duct pressure set point. o OUTSIDE AIR DAMPER CONTROL: • Proportional damper reset:The unit controller will proportionally modulate the outside air dampers open and closed as the supply fan speed changes to provide a constant volume of fresh outside air. • Outdoor air monitor:The unit controller will modulate the outside air damper as required to maintain the outside air cfm setpoint as measured by the factory provided flow station (Requires Optional OA Monitor). • DCV:A space or duct mounted CO2 sensor will supply a PPM reading to the unit controller. The unit controller will open the OA damper to provide more ventilation air as required by the CO2 PPM reading(Requires Optional CO2 Sensor) • External Reset:An external 0-10 VDC or 4-20 mA signal can be wired to the unit controller to control the OA damper position by a third party. o COOLING: • Discharge Air Control: In the cooling mode,the unit capacity will modulate the variable speed compressor to maintain the unit cooling discharge air set point. The cooling DAT set point will be adjustable at the unit controller. Unit capacity will be modulated by the variable speed compressor operation. • Cooling DAT reset:The cooling DAT setpoint may be reset by the space temp, return temp,OAT or external Voltage/mA signals.

Outside air and return air dampers shall modulate to maintain supply air temperature set point. o EXHAUST FAN CONTROL: If the optional exhaust fans are provided they will be direct drive electrically commutated motor(s)(ECM). If powered exhaust is not provided barometric relief dampers are standard.

Heating DAT reset: The heating DAT setpoint may be reset by space, return,OAT, Network or external Voltage/mA signals. A linear relationship between the DAT and the reset variable will be created for the minimum and maximum DAT setpoints.As the reset variable changes the DAT will adjust according to the relationship.
