condenser) at a temperature of at least 85° F. On a cool day, the components can be heated with a
heat gun OR by running the engine with the heater on before evacuating. Leak check and charge to
specifications.
The Proper Amount of Refrigerant is Critical to Proper System Operation.
Vintage Air Recommends Our System be Charged by Weight with a Quality
Charging Station or Scale.

Control Panel Dimensions
Control Panel Installation
Select a suitable location for the control panel, considering heater control valve location, wiring harness length
and operator convenience.
After selecting a location for the control panel, mask the area 2 ½” (tall) x 6 ½” (wide).
Using the dimensions provided above, mark or scribe the control panel opening location onto the dash.
When you are certain that your dimensions and markings are correct, cut the dash to make the control
panel opening. NOTE: Measure twice. Cut once. This opening MUST be a precise t. Cut the opening
undersize, and then le to t. The mounting screws only hold the panel against the dash. They do
not locate the panel laterally. If the opening is oversized, the panel may shift during use.
Install the control panel face through the opening in the dash. Place the control panel PC board assembly
behind the dash, and secure it to the control panel face using the (4) 8-32 x 3/8” screws (See Figures 1 &
2, below, and Figure 3, Page 5). NOTE: When tightening the control panel mounting screws, hand
tighten until the screw contacts the back side of the dash. Then, using a screwdriver, tighten an
additional 1/2 turn. Do not over tighten, as this may cause damage to the PC board or the dash.
