We changed out one of ours in 2013. The kit for the gaskets from Newmar is part #017841
I have a PDF of the Newmar instructions but can't attach :(
PM me with an email and I can send it to you if you haven't found it on the Newmar site.
we had a question on the install instructions and received this response from Newmar (that may be helpful for you - copied below).
Hello,
Thank you for your email, and I would be glad to answer your question. When we factory install the heat pumps we will put a thin layer of clear silicone under the pad to ensure proper seal, then we would lag the heat pump unit down to compress the pads and the gasket to 50%. After the fastening down of the unit is complete we then will apply silicone on top of the lag bolt and let it run down around the lag to again ensure proper sealing. I’m not sure where you purchased your heat pump from or if they let you know it is essential that the dip switches be set to match the unit you are replacing. If you have any more questions please let me know.
Thanks,
Craig Garl
