Air Conditioning Climma Marine Compact 9 The original Air Conditioning Climma Marine Compact 9 in the aft cabin stop working (and was tripping the boat power as well as the marine shore power). Since a new unit will take 3 months to arrive, I decided to swap the forward and aft air conditioning units. An easier option would have been to sleep in the forward cabin You will see the removal of the aft and forward cabin air conditioning. Then reinstallation of both units with unexpected complications of the fan and bracket holding the control boxes It is common sense that the power to the air conditioning units should be turn off at the 220 Volt panel (diruptor) before doing anything.

Air Conditioning Climma Marine Compact 9 EH Thermostats and control box removal

Not necessary to swap the air conditioning, but I removed the control panel in order to test the unit in the cockpit.
Unscrew the 2 bolt holding the panel.

It is preferable to switch off the 220 Volt outlets, which I did not do in order to have a fan cooling me off
I was always very careful not to couch the plug.

Turn the 2 screw, to open the panel

Slide the panel out of the way.
Now you see the compressor

Remove the filter

I started to unscrew the cover of the control box only to realize I need to let it loose from the bolt

Cover removed

Now I am getting the control box loose.

You can see the 3 capacitors for the fans

Disconnecting the current of the Aft Climma Marine Compact 9 Control Box and testing voltage

Then inside the 2 to start the compressor
I did not get shock, but was told it is possible and hurts.
You are supposed to "discharge" the capacitors.

At first I thought I found my problem, but in fact this was from a previously burnt capacitor.

Removing the top of the control box

inside view

Here is the timer set on 15 or so seconds.

The 3 wires going to the 220 volt panel

Now removed - then I put clamp on them

Then I turn the Diruptor on the 220 Volt panel

Then I measure 230 Volt of electricity.
This allow me to confirm there was no short in the wiring going to the air conditioning unit.
Then I Switch Off the Diruptor on the 220 Volt panel.

Disconnecting the harnesses of the Aft Climma Marine Compact 9

I randomly named the first harness "A" as I will find out later, it is going to the Compressor

I took note of the wire position and removed the blue, white and red wires

Then the brown, blue and ground (yellow/green) wires

Here is a picture of my notes

Then I label the second harness "B", as I will find out later it goes to the fan

I took note of the wire position and removed the brown, blue, black, ground (yellow/green) and grey wires

Here is a picture of my notes

Disconnecting the Calpeda pump and control harness of the Aft Climma Marine Compact 9

I labeled the wire going to the Calpeda pump then removed them

Here is the harness going to the control box

Easy to unplug including the ground

Now the control box is completely disconnected

Disconnecting the air duct and cooling hoses of the Aft Climma Marine Compact 9

remove the clamp holding the hose

Removing the hose of the overflow (this was actually quite difficult)

Remove the clip holding the cooling water to the compressor.

I realize how important are these clamp, should there be a failure water would fill up quickly in the boat from the calpeda pump.
They are two clamp and a metallic wire holding the second one

Hose removed

Same on the other side

Hose removed

Removing the thermostats and holding brackets of the Aft Climma Marine Compact 9

Now unscrewing the attach

Close up of what is holding in place

2nd one

3rd one

and 4th one on the side

Now can use the handle to slide the unit

but before, let's not forget to remove the thermostat

sliding the unit

Now out

A look at the other side

Removing the thermostats control of the Aft Climma Marine Compact 9

Not necessary to swap the units, but necessary in my test, I removed the thermostat adjuster

Remove the cover with a screw driver

Pull the cable out

uncrew the cover

Pull out the unit
again careful that the electric outlet above is either off or stay away from it

Removal of the forward cabin Air Conditioning Climma Marine Compact 9

Disconnecting the cooling hoses of the forward cabin Air Conditioning Climma Marine Compact 9

Empty the cabin and open the 3 panels

Close the valve that reject the cooling water

In my case, it appears frozen and I did not want to risk adding another problem, so I did not close it, but prepared with towels and plugs

Removed the 2 clamps, same as the aft cabin there is also a metallic wire attached on the 2nd clamp.

Very little water went and I put the plug.

Also removed the 2nd hose, put a plug and position these high above the water line.
You can see the 2 metallic wire holding the 2nd clamp in position

Remove the clamp holding the air hose

Removal control box of the forward cabin Air Conditioning Climma Marine Compact 9

unbolt the wheel holding the control box

Take the control box out and remove the cover

Cover out, now you see the 3 capacitors for the fan speed.

Unbolt the box cover

Capacitor testing of the forward cabin Air Conditioning Climma Marine Compact 9

Now you can see the 2 capacitors for the compressor
note: you don't have to remove the cover to access these capacitors, you can just pull them out.
Note: careful as the capacitors are "charged" and need to be "discharged".
I won't write much about discharging them as I am not sure.
I used plier to remove the connector of the 10 MicroFarrah capacitor
Take note of which wires goes where.

I measured the micro Farrah of the 10 MicroFarrah capacitor and it shoed 5.2 so will be changed

Now the 40 MicroFarrah capacitor
Take note of where the wire go

The 40 MicroFarrah capacitor show 39.9 so well within the +/-10% allowance

With a small screw driver, I removed the top the 2 MicroFarrah capacitor

Now removed

The 2 MicroFarrah capacitor shows 0.5 and will be changed

next below is the 3.5 (or 3.15 can't remember) capacitor

Removed

Also showing less than the 3.15 o 3.5 so will be changed

Last is other 2 MicroFarrah capacitor

removed

Also need to be replaced.

Disconnecting the Calpeda pump, AC (Alternative Current) wire and control box of forward cabin Air Conditioning Climma Marine Compact 9

Removing the wires going to the Calpeda pump

removed

Since the forward air conditioning will not be replaced for some time, I protected the connector to avoid any short.

Next is the AC (Alternative Current) Power connection

All 3 wires removed

And labeled. I also protected them in the accidental switch of the Diruptor going to this unit.

Removing the connection of the control box, removing the ground

Then removing the plug

Disconnecting the Compressor and Fan harnesses of the forward cabin Air Conditioning Climma Marine Compact 9

Removing what I called Harness "A" and "B" - make sure to take notes where the wires go

Here is a picture of my notes for harness "A" going to Compressor

Here is a picture of my notes for Harness "B" going to fan

The control box is off

Removing the thermostats and brackets holding the forward cabin Air Conditioning Climma Marine Compact 9

Removing the 4 attach point that hold the unit in place

Clip out

2nd one

3rd one

4th and last one

Then removing the hose for the condensation - more difficult than it sounds

Hose is off

Now using the handle you can more the unit

let's not forget the thermotat

Cutting the little zip tide that hold the thermostat

The unit can now be lifted

Through the hole

Bolt it in

Put the cover plate

Put the harness through the hole

Next level down

Lower level

Then put the thermostat

Through all levels

Changing the hose direction of the Aft cabin Air Conditioning Climma Marine Compact 9 to later realize it will not fit

Original unit in the aft cabin has the hose pointed in one direction

Original unit in the forward cabin has the hose pointed in a different direction

So naturally I thought of changing the directions - unfortunately this was wasted time
look at the pictures before you do the work

unscrew in the middle

4 bolt total

unscrew the plate that hold the fan

2nd bolt

the plate goes out

Put it back the plate turning it 90 degrees

put bolt on

and the 4 in the middle

Bring the unit to the aft cabin

And it does not fit...

Comparing the Aft and Forward cabin Air Conditioning Climma Marine Compact 9

unscrew the elbow

remove its

unscrew the elbow that was on the original aft cabin air conditionning

Now we see the difference

Look at the forward cabin one again

If we put it on the new unit, it might fit

but I don't like the obstruction

I could saw it, but this is now the way I want to do it

Putting the wires

putting back the cover

Going to bolt back the box

Swapping the control box and attach of the Aft and forward Climma Marine Compact 9

But it will not fit... because the control box coming from the forward cabin is hold through a bar at the end

While the control box in the aft cabin is hold by a braket.

So removing the bracket

Removing the 2 bolt/nuts that hold the plate

close up look

Plate is removed

put back on the other unit

Unfortunately I forgot to take a picture, but I had to drill 2 holes in the other plate in order to fit the bracket

Put the cover back and now you can bolt it back on

Reconnecting the fan assembly on the forward Climma Marine Compact 9

Putting back the half fan assembly on the plate

Passing the wire through the hole

Quick reconnection of the harnesses, Capacitors of the forward Climma Marine Compact 9

As detailed for the other unit, put back the fan harness

Here is a picture of my notes for Harness "B" going to fan

Now in place

Now the compressor harness

Here is a picture of my notes for harness "A" going to Compressor

Now in place as well as the 3 capacitors on the side

Put the 2 larger capacitors and close the cover

Position the capacitors

Position the wires

Since this unit is NOT working and to avoid any risk to trip the main breaker should the Diruptor of the 220 Volt panel be activated for this unit
I will not reconnect the AC (Alternative Current) wires and make sure they are well cover and away from each other.
Same for the calpeda pump, which I believe has current coming to these wires.

Put back the cover

Bolt in back (we previously exchange the brackets)

Testing Climma Marine Compact 9

Before I close everything down (forward cabin access to the air conditioning and the cover of the aft cabin)
I wanted to make sure the hose were not leaking as it would be desastrous
So I turn on the aft cabin air conditioning
Then inspected for several minutes to make sure there was water leak on both hoses

Then look at the hoses of the forward cabin

All good

Putting back cover for Aft and Forward Climma Marine Compact 9

Now time to close down everything

Putting back the Aft Climma Marine Compact 9

Before putting the panel

Will nicely secure the wires
