Fan Coil Unit falls principally into two main types: As the names suggest, in the first type the fans are fitted such that they blow through the heat exchanger, and in the other type the fans are fitted after the coil such that they draw air through it. Draw through units are considered thermally superior, as ordinarily they make better use of the heat exchanger. However they are more expensive, as they require a chassis to hold the fans whereas a blow-through unit typically consists of a set of fans bolted straight to a coil. A fan coil unit may be concealed or exposed within the room or area that it serves. An exposed fan coil unit may be wall-mounted, freestanding or ceiling mounted, and will typically include an appropriate enclosure to protect and conceal the fan coil unit itself, with return air grille and supply air diffuser set into that enclosure to distribute the air. A concealed fan coil unit will typically be installed within an accessible ceiling void or services zone.

In the Draw-Through type, the fan pulls the air through the mixing box, filters and cooling coil before discharging it from the fan outlet to the space to be conditioned or to the ducting network. The design can be vertical or horizontal. In this case, the section before the fan has negative pressure. In the Blow-Through type, the fan blows the air through the mixing box, filters and cooling coil before discharging them to the space being conditioned or the ducting system.

In this case, the section after the fan has positive pressure. Components of Air Handling Unit Here are some of the air handling unit components that may be contained in the equipment. Housing The housing that contains all the other components of an AHU is usually make of metal, some are painted to prevent corrosion. In sections where the fans and the coil are located, inches of polyurethane foam or PU is used to insulate them to prevent the condensation on the panel.

Drain pan is also used as a precaution in the event of condensation of water. Fan Centrifugal fan is used to circulate the air to the various parts of the sections in the building.

Sleek black flat panel that has two old school rabbit ears in case you need them. Sue So I cut the cord and was satisfied for awhile. Nobody wants to admit it but the cable company is scrambling the signals so that I have to get cable. Luckily I am 67 years old and will not have to put up with this B. I remember trying to tune in the TV with rabbit ears and fuzzy television viewing. Dennis Restauro Hi Sue. I checked the signal power in your town and it should be fairly easy to pickup channels if you point the antenna to the west.

That said, I am posting this on his behalf as he brought an item out today and said “i’ve never been able to figure out what this is” and I said “we’ll figure it out dad” but I have no idea how. I wish I’d gotten a little better description but here are the pics. It is a heavy object, he claims it is brass. It is about 6 inches in length, being maybe inches wide. It has some sort of a post coming out of the bottom that I have to assume was originally used to insert into something or other.

It has two flat-tish sides that look like they were originally meant to house string or something.

Description[ edit ] Moai set in the hillside at Rano Raraku The moai are monolithic statues, their minimalist style related to forms found throughout Polynesia. Moai are carved in relatively flat planes, the faces bearing proud but enigmatic expressions. The human figures would be outlined in the rock wall first, then chipped away until only the image was left. The lips protrude in a thin pout. Like the nose, the ears are elongated and oblong in form.

The jaw lines stand out against the truncated neck. The torsos are heavy, and, sometimes, the clavicles are subtly outlined in stone. The arms are carved in bas relief and rest against the body in various positions, hands and long slender fingers resting along the crests of the hips, meeting at the hami loincloth , with the thumbs sometimes pointing towards the navel. Generally, the anatomical features of the backs are not detailed, but sometimes bear a ring and girdle motif on the buttocks and lower back.

Except for one kneeling moai, the statues do not have clearly visible legs. Though moai are whole-body statues, they are erroneously referred to as “Easter Island heads” in some popular literature. This is partly because of the disproportionate size of most moai heads, and partly because many of the iconic images for the island showing upright moai are the statues on the slopes of Rano Raraku , many of which are buried to their shoulders.

Those of us who inspect and repair HVAC systems for a living know that with the start of the AC season, the phone will begin to ring with cries from hysterical customers frantic about water dripping from their ceilings and water-soaked floors. Condensate may be behind their falling plaster and drenched carpets due to improper collection and control of this cooling-mode byproduct. As air passes through the cooling coil of an air conditioner or heat pump, its temperature is lowered below the saturation point.

While simultaneously hugging the fins of the coil and moving downward, moisture sucked from the air begins filling a collector positioned under the coil, which manufacturers call the primary condensate drain pan or just the condensate pan. As the pan fills, it must continually drain to prevent it from overflowing and causing damage to the equipment and to the surroundings. The pan also must drain quickly and completely to prevent it from becoming an unhealthy pool of contaminants. Failure to do so can lead to personal and real property damage and even to life-threatening illnesses.

Cased coils or coil boxes are often attached to furnaces. Photo from Carrier Literature Blow-through and draw-through systems The evaporators of air conditioners and the indoor coils of heat pumps, both used for cooling in summer, are installed so that a blower either pushes or pulls air over their cooling surfaces. When air is pushed across, putting the coil under positive pressure, it is considered a blow-through or positive pressure system.

Start the pump-down operation 3 to 4 minutes after the power circuit breaker is turned on. The compressor and venti- lators indoor and outdoor units start operating refrigerant collecting operation begins. However, even if the unit is stopped and the pump-down SWP switch is pushed less than 3 minutes after the compressor stops, the refrigerant collecting operation cannot be performed.

Wait until the compressor has been stopped for 3 minutes and then push the pump-down SWP switch again.

Air Handling Unit (AHU): a device used to condition and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. An air handler is usually a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers.

Hi all, I’ve back in the caddy game It’s a pretty honest truck, it’s had mods as you can see but the body work is original, it’s pretty solid and it hasn’t been messed about with much. It will be a pretty slow project, but the general plans are: Keep the paintwork original, I’m not fussed by the knocks and dings as it’s all original. The rear bulkhead needs a repair and maybe carry out some work to get the rear bed in better condition and to prevent the bodywork deteriorating.

I have a lockable chest and rear bed cover which lifts on hinges to fit from one of my old trucks. But I’ll have a think about what’s possible to modify it as I’d like it to be easier to carry 6″ x 4″ boards in the back. Interior needs some work as the original items were taken out and replaced with mk3 seats, part finished door cards and a sporty steering wheel. Generally back to a nicer version of the original and maybe a bench seat.

I did the coding myself. After coding, the backup camera trailer zoom works fine. Because I don’t have a real trailer now, I plugged in Curt circuit tester like this: So I am ok with that. Left turn, right turn, backup, taillight all work fine. If I depress brake pedal, brake light is NOT on, but both left turn and right turn lights are on. Yes, that is all correct. LED don’t draw enough current so they cause the issues you mentioned: VW had a TSB on point:

Two hours later, the Chilean Armada sped from the island and retrieved El Capitan in a panga. The swell had tempered, but it was still too massive for them to simply tie up to the Red Thread. The entourage bobbed around and completed clearance procedures. The only way ashore is to race your dinghy between sets of breaking waves to the dog-leg turn that opens to the safety of a small fishing harbor. It is a hair-raising experience to say the least, but we subjected ourselves to it day-after-day as a price to pay to explore the island and learn more about its history.

Here is what you need to know. Everyone else tries to make believe that the EMU is simple in setup and function, and it is not and pretending that it is simple, we believe is a dis-service to customers. I made this for you. Read the notes too, please. The manufacturer highly recommend that you avoid plugging into a power strip or a GFCI electrical receptacle aka outlet or plug. This can increase the “noise” and make it so your EMU won’t communicate as well or at all.

Yes this does mean you may need to plug your existing stuff in, in some other way. You can try it, just don’t complain to us if it doesn’t work out. You know what a GFCI is right? That is the special type of outlet that has a test and reset function on it. But you can also have a GFCI that is located somewhere else, like at another plug upstream of the plug you are using, or even at the circuit breaker panel.

One reason that the customer must be involved in some of this stuff, is because there is some trial and error involved, and every time you plug the EMU in, you may have to hit the “Menu” button which is on the back of the EMU. To make matter more complicated than they really need to be, they molded the button into the back plastic so that you can’t even see it.

Well look close, and you will see it.
