Dimensions
The unit is a packaged rooftop unit designed for DX Cooling and Electric Heat. Diagrams illustrate its physical layout and connection points.
Overall Unit Layout: The unit features access panels for the Evaporator Section, Control Box, and Compressor. It includes a Condenser Fan, Condenser Coil with Coil Guard, and designated holes for unit control wiring (7/8" dia.), service gauge ports (1 3/8" dia.), and unit power wiring.
Drainage: A condensate drain connection is provided, typically a 3/4"-14 NPT DIA. HOLE.
Airflow Openings:
- Downflow Configuration: The plan view shows distinct SUPPLY and RETURN air openings. The dimensions indicate the placement and size of these openings relative to the unit's footprint.
- Horizontal Configuration: A separate view shows the openings for horizontal airflow, again with SUPPLY and RETURN designations.
Key Dimensions:
- Baserail Length: Approximately 88 1/2 inches.
- Baserail Width: Approximately 53 1/4 inches.
- Other dimensions include height (4.24 ft), width (4.44 ft), and length (7.34 ft) as noted in the Unit Overview.
Weights and Clearances
The unit requires specific clearances for proper operation and maintenance. The diagram indicates these zones.
- Clearances: Specified clearances include 36 inches on multiple sides, 48 inches on one side, and 72 inches on another, depending on the airflow configuration (horizontal vs. downflow).
- Approximate Installed Weight: 964.4 lb.
- Corner Weights (for base unit only):
- (A) Corner Weight: 341.0 lb
- (B) Corner Weight: 318.0 lb
- (C) Corner Weight: 183.0 lb
- (D) Corner Weight: 196.0 lb
Note: Installed weight includes all selected options and accessories. Corner weights do not include options or accessories.
Wiring Diagrams
Symbio 700 Wiring (Field Wiring Drawing)
The Symbio 700 control system connects to various components via terminal blocks. Key connections include:
- ACNET: ACNET OUT (+/-) and ACNET IN (+/-) for network communication.
- Zone Sensor: Connections for ZONE TEMP and COOLING SET POINT, with terminals labeled 1 through 7.
- Building Automation System (BAS): Terminals for 24 VAC OUT, COMMON, and other control signals (e.g., 1Y, 2Y, 3Y, 4Y) for integration with a BAS.
- Optional Remote Sensor: Connections for SPACE HUMIDITY and LOCAL OCCUPANCY, with 24 VDC OUT and COMMON terminals.
- Thermostat: Connections for T-STAT Y1, W1/0, G/VAV CHANGEOVER, W2, Y2, X2, PULLDOWN-T, and GND, with 24 VAC OUT and COMMON terminals.
- CO2 Sensor: Connections for CO2 IN and COMMON, with terminals labeled 1 through 3.
The diagram references specific terminal blocks like J17, J18, J19, J20, J21, J22, and J23 for the Symbio 700.
Optional Electric Heat Wiring (Field Wiring Drawing)
Connections for optional electric heat stages are shown:
- Electric Heat Stage 1: Wired via terminal block P6 J6. Connections include COMMON, 1 BK (Black), and 2 2R, leading to HC1 A/B.
- Electric Heat Stage 2: Wired via terminal block P7 J7. Connections include COMMON, 1 BK (Black), and 2 2R, leading to HC2 A/B.
Fan Performance Curves
The document includes fan performance curves illustrating the relationship between Airflow (CFM) and External Static Pressure (in H2O) for different fan operating conditions.
Configurations: Curves are provided for both Downflow and Horizontal airflow configurations, specifically for the TSJ072-120* model.
Parameters Displayed:
- Airflow (CFM): The horizontal axis represents the volume of air moved.
- External Static Pressure (in H2O): The vertical axis represents the resistance the fan must overcome.
- Fan Speed (RPM): Various curves indicate performance at different fan speeds (e.g., 800 RPM to 1900 RPM).
- Motor Horsepower (bhp): Dashed lines indicate the power consumption of the fan motor at different operating points (e.g., 1 bhp, 1.50 bhp, 2 bhp, 3.1 bhp, 4.6 bhp, 5 bhp).
- Wet Coil (WO) and Airflow Percentage: Some curves are labeled with percentages (e.g., 45% WO, 50%, 60%, 70%, 80%, 90%) which likely relate to airflow modulation or operating conditions.
Note: The fan curves are applicable to TSJ/WSJ units. For YSJ units, additional static pressure must be accounted for when using a Gas Heat Exchanger.
