TO: Steve Pickar, CDI Curbs Job # 18-001T
FROM: Aaron Weidman EIT., VAK Engineering
PROJECT: Stock Isolation Curbs C7-00XX-7720, Q1029509, 250084 DATE: 12/11/2018
As requested we have designed a fastening scheme for the 7720 units and their corresponding sheet
metal curb. 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 SDS = 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) 1/2" 0 A307 bolts or equivalent are required along each long edge of the curb
Filename: 18-001 T LTR01 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 1/4" 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"O 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.
Please feel free to contact us should anything further be required or if questions arise.

Aaron Weidman, E.I.T.

SegOfOperation Doc D_Drawing for RTU-1
Sequence of Operation Specifications:
o UNIT CONTROLS:
• Building Automation System(BAS) interface:The factory unit controller will interface with BACnet
MSTP, IP and LON BAS systems (requires optional communication card).
• Head Pressure Control:The condenser head pressure will be monitored by the unit controller to
maintain head pressure and the compressor operating envelope at all times to avoid high pressure
trips on high load days. 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. A linear relationship between the DAT and the reset variable will be
Job Number: WTZ8Z4 Page Prepared Date: 3/18/2019

SegOfOperation Doc D_Drawing for RTU-1
created for the minimum and maximum DAT setpoints.As the reset variable changes the DAT will
adjust according to the relationship.
o ECONOMIZER: A comparative dry bulb(standard option)or comparative enthalpy(selectable option)shall be
engaged whenever the outdoor enthalpy or dry bulb is less than the return air enthalpy or dry bulb to utilize
outside air for cooling. 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.
Powered exhaust control options are as follows:
• Building pressure Control: A differential pressure transducer shall compare the indoor building
pressure to ambient atmospheric pressure. The exhaust fan(s)shall modulate to maintain the
building pressure set point.
• Speed Control:The exhaust fan(s)will run at a constant speed.
• Network Control: Exhaust fan speed is commanded from the building automation system.
• Outdoor Air Damper Tracking: The exhaust fan(s)will activate based on the outside air damper
position and will modulate between an adjustable minimum and maximum as the OA damper opens
to provide relief.

Sequence of Operations
GAS HEAT
The unit is provided with staged or modulating gas heat.
• Modulating Gas Heat:The modulating gas heat will be modulated by the unit controller to maintain
the heating DAT set point.
• Staged Gas Heat:The staged gas heat will increase or decrease stages based on the stage timer and
whether the DAT is greater or less than the effective DAT setpoint.
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.
