Dimensional Drawing - Indoor Unit Vertical AHU 45VMV048A---3
A clearance of 25 inches is required in the front of the unit for filter and coil maintenance.
The diagram shows the unit with electrical connections potentially exiting the top or right side. It features high voltage connection knock-outs (7/8", 1-3/8", 1-3/4" diameter), wire groups for thermostat and outdoor unit connections, and an EHK knock-out hole. The unit has flanges for field installation. Pipe connections are indicated for vapor line (braze), liquid line (braze), and auxiliary drain (3/4" Female pipe thread NPT) on multiple locations, along with a primary drain connection (3/4" Female pipe thread NPT). The unit is shown in an upflow configuration but can be installed for upflow, downflow, horizontal right, or left air supply.
Dimensions are provided: Width 22-1/8 inches (560 mm), Depth 19-1/2 inches (496 mm), Height 54-1/2 inches (1385 mm), Depth 24 inches (610 mm).
Notes
- 1. Performance data based on Indoor temperature 80°FDB, 67°FWB; outdoor temperature 95°FDB, 75°FWB; equivalent refrigerant piping length 295-1/4 in. with zero level difference.
- 2. Performance data based on Indoor temperature 70°FDB, 60°FWB; outdoor temperature 47°FDB, 43°FWB; equivalent refrigerant piping length 295-1/4 in. with zero level difference.
- 3. The AHU utilizes a special-shaped heat exchanger with varying rows and tube pitch for optimal performance.
- 4. Fan motor speed and airflow rate are provided for 7 distinct levels, from highest to lowest speed.
- 5. The stable operation external static pressure range is 0.2 in (wg). Operating outside the optimal static pressure range may increase noise and decrease airflow. Refer to the installation manual for optimal ranges.
- 6. Sound pressure levels are provided for 7 distinct levels, from highest to lowest. Measurements were taken 59-1/16 inches below the unit in an anechoic chamber.
- 7. Dimensions provided are for the unit body only, excluding installation lugs and connecting copper pipes. Refer to the installation manual for detailed dimensions.
