I like that answer.

If you ever open an East coast branch, I want to be on your customer list!

It's fine the way it is Jimi…It will only draw air thru the fins…

The older Cruisair units didn't have that Cork insulation tape, Marine Air & other brands never had it….Cruisair later used foam insulation tape…It was more to show off quality than function…

Follow-up question:

 

The air handler in question is open on all sides to the ambient air in the cabin. The intake grill is fairly well closed off so that air is routed through it by way of a wooden frame that fits around the grill and is faced with trim ply. My question is whether or not it would be beneficial to go on the backside of the unit, and build some sort of enclosure so that the only air that goes to the cooling fins of the grill would come from the front. As it is, the black mastic still seems to be covering any gaps around the back, so I don't think ambient air is getting from the back of the unit to the cooling fins, but can't be sure without pulling it out of the cabinet. It would be fairly easy to fabricate a more air-tight enclosure with insulation board...would there be any benefit to doing so?

Thanks for the quick reply Steve. Would it be just as effective to wrap it with some of the thin foil-backed insulation I can get at Lowes and secure it with metal tape ( to help reduce condensation) or should I just leave well enough alone?

Hi Jim~

It's not that important...It will just sweat more without it...As long as it drips into the pan (and from your description of ends of coil it should) and then the drain is clear to drain it...Just slightly more condensate production is all....

I opened up the air handler to get to a plugged drain pan line, and found that a lot of the black, heavy, tape-like substance that had been wrapped around the unit and covered much of the ends of the coils had hardened and fallen off.

Do the coil ends need to be covered with this stuff?

Should I find some new stuff and re-wrap everything, or is it OK to leave it off?
