Air and Heat, Plumbing

The plumbing on the front end was completed without difficulty. The section of pipe which included the trinary switch is designed to be used on either a right or left hand drive car. That means on a right hand drive car it points down but on a left hand drive car it points up. We did not want it pointing up. A replacement was fabricated pointing downward. Minor point, but we wanted to keep the area above the plumbing clear.

The large fitting which passes through the front wall has a retaining nut. But the AC fitting could not be tightened down with this retaining nut installed due to the thickness of the chassis. This could be a trap, since one would assume it is tight when in fact it is not. One could perhaps ream out a bit of the chassis so the retaining nut could be tightened further or grind down the nut a bit. We simply removed the retaining nut and made a thick rubber washer to fill the space. Not as elegant as a nut, but this connection won’t be going anywhere and will not be stressed.

The smaller fitting tightened down without difficulty.

This is a really nicely designed system that looks good installed. Fran and his crew have clearly done a lot of research and development to put this heat and AC system together. Although Hot Rod Air supplies the hardware, the system is unique to the RCR cars. I am anxious to get it charged and operational.
