E40 Air Conditioning
Date: January 25, 2002
From: John Bartoszek jbartosz@symbol.comGetting ready to head south sometime this year and am planning to install A/C (with heat). If anyone has factory installed or self installed A/C, I would be interetsed in knowing where the unit(s) si, supply locations, return locations, cooling water inlet and outlet, pump location and any other pertinent info. I have and E40 with a counter top and HUGE icebox (which we use for dry storage) along the entire port side (no nav station or hanging lockers).

My nav station is on the starboard side. Just behind it is a hanging locker located across from the engine room doors. That is where the a/c compressor is and the outflow is located on the forward side of that locker. Return air comes from below. Another small outlet is located on the starboard side at the aft stateroom just ahead of the hanging locker there. I just have one 16,000 btu unit & it does fine for the entire boat. If we have company in the V-berth, we have a fan to push more air to the front end of the boat.

We too own an E-40 with a Cruiseair system. It was installed at the time we purchased the boat (1991). It was installed in the engine room, below the battery boxes. Or another way to look at it, it is just above the fuel tank and up against the forward bulkhead, the one that separates the engine room from the salon. This affords a location for the return air as well as the condenser. The discharge air comes out just below the top of the companionway ladder. We have two additional outlets, one which discharges into the galley and one to the owner's stateroom aft. Believe me the discharge into the galley, while not large, really keeps the cook happy. The intake water comes from the aft, starboard thru hull (scupper drain). That particular drain is tee'd into the forward scupper drain. The filter is located just inside the door to the engine room. The water outlet is in the aft head, well above the water line. We have a separate shore power line. This allows the operation of the AC and heat regardless of the power requirements on the rest of the boat. You may get by with a single line but we have a 2000w microwave plus the 10 amps for the hot water heater, thus the ac amperage can get quite high.A possible unique problem we ran into in the winter time with the system running was that small fish would get into the intake water line. This would cause the system to shutdown. By having the intake waterline accessible, it made getting the fish out simpler.
If you have any more questions, do not hesitate to contact me.

From: David Olson OLSON@tbcnet.comI have a 38cc w/ 2 AC units. 1 is located in the aft cabin, starboard side next to the batteries. The second is in the forward v berth, starboard side under the berth. The air duct passes through the hanging locker and opens to the main cabin on the bulkhead above the hanging locker. The through hull forward is just aft of the bulkhead, slightly starboard of center. The aft through hull is under the starboard galley sole, 2 feet forward of the aft cabin door. The aft unit only cools the aft cabin and discharges the cool air just above the unit on the starboard side. These units have kept the boat very comfortable in 95 degree heat w/ no problems. ( We have a navy blue hull w/ white topsides).....Oh, both discharges are on the starboard side, near the units themselves.

From: David Olson OLSON@tbcnet.comSorry, I forgot to tell you, these were factory installs. And I was mistaken on the intake...there is only one, it is under the galley sole, The pump (1) is shared and in the engine room against the starboard wall. The suply then splits and goes to each unit But they both have their own discharge.

From: BLUEFT@aol.comI HAVE AN ENDEAVOUR 40 WITH A 16,000 UNIT CURISE AIR. I INSTALLED IT OVER MY BATTERY BOX IN THE ENGINE ROOM. THE AIR BLOWS JUST TO THE STARBOARD OF THE LADDER. THE INTAKE IS UNDER THE LADDER. THE WATER FOR IT IS A THROUGH HULL NEAR THE ENGINES THROUGHHULL. THE OUTPUT IS ON THE STARBOARD SIDE UNDER THE SINK AREA. YOU CAN REACH ME AT BLUEFT@AOL.COM

From: Jonathan Richards Endeav35@aol.comI just acquired an E38 and previously spec'd my old E35 for A/C. My E38 has a 16,000 Btu air/heat unit for the main saloon on forward cabin. This unit is located under the v-berth forward under the starboard berth. This is same location we were going to utilize for the E35 unit as it this location allows the use of the Bureau in the forward cabin which has a corresponding one in the main saloon to be used as a chase for the ducting. The return under the starboard side of the v-berth. The second unit is a 5,000 Btu air only located under the counter top along side the island berth in the E38. If I recall the E40 layout the aft cabin berth is oriented thwartships so perhaps it could be placed under the berth if there is room or in any of the built-in cabinetry in the aft cabin, using that cabinetry for the ducts. There is generally plenty of room in the cabinetry for ducts as they are much deeper than is used by the drawers. Unfortunately, I am not as familiar with the E40 layout. As to the intake, mine is piggybacked of one of the other intakes, it seems for some reason a dedicated intake has been sealed off. I haven't found where is hooked into as of yet.

From: Luther Carrier captaincarrier@yahoo.comJohn,
In regards to your AC; I installed a single unit in my 33E, unlike yours which I would think would require two smaller units. Things to consider, power supply, water supply and available space for unit(s) and duct. There are many other little items but none to sweat. I placed my under the v-berth and ducted thru a dresser, builded a plenum on top of the dresser with supply grilles, two to aft and one forward. The return, I cut in under the v-berth. The thermostat is out of the air flow and sun near the face of the hanging locker. I added a second 30 amp plug for additional shore power and placed the Cal pump and strainer on a removeable panel. I suggest an over sized strainer so the flow slows down and the trash falls out and then removed. Try to keep your electrical runs as short as possible (which I did not) this will reduce cost considerably. Total install time (not including running for parts and hand fabricated pieces), I started in October and finished in April, since I work and have many other interest, the total hours to date come to 22 manhours.

From: Julian KennamerThought I might "refresh" this ten year old thread. I too have an E-40, 1982, Hull #167. I installed a 16,000 BTU reverse cycle Marine Air unit in the engine room against the forward bulkhead. I removed the old battery box and installed and secured my house batteries (2x4D gels) on the floor of the engine room under the shelf. This had the beneficial affect of getting a lot of weight lower in the boat. I then rehabbed the shelf where the batteries had been and installed the ac on the shelf. A rectangular opening was cut in the galley bulkhead beneath the pantry and the units condenser grill was abutted up to the opening inside the engine room. The teak grill was placed over the opening.
There are two air discharge supply grills: 1) a large one high up on the bulkhead beneath the companionway steps (which cools the saloon, galley and, to a less extent, the v-bearth), and 2) the second smaller one was cut into the bulkhead (and mirror!) that is common w/the engine room and aft cabin (keeps us chilly!). The duct for the aft cabin outlet was simply routed thru the upper ceiling area of the engine room. The water for the circulation pump is supplied thru a seacock that was installed under the raised portion of the aft cabin sole, hose routed to sea strainer mounted in engine room, then to pump on small shelf constructed under shelf ac unit sits on. The water discharge is via a hose run under the galley sole and sink to the port-side hull. The control is high up on the bulkhead just around the corner from the distribution panel.
The system is relatively simple to install and has worked flawlessly. There was even room left on the shelf to install my starting battery next to the ac unit. High and dry in case of an emergency.
