5. BEFORE FITTING THE SKIMO A/C UNIT
Prior to fitting and using the Skimo A/C unit, check the following points:
Cabin volume: Ideally the volume of the cabin is approximately 2m
3
but if it is over 3m3 the performances of the Skimo
A/C unit will decrease.
Cabin insulation: The cabin walls must be properly insulated, especially from important heat sources (engine, exhaust
pipe, hydraulic system …). SNDC SAS cannot be held responsible in the case of poor performances of the Skimo A/C unit
caused by poor cabin insulation.
Ceiling thickness: The ceiling thickness must be between 3mm and 60mm. If it is over 60mm, an additional plate can be
fitted to fasten the cabin panel. In this case, the four M8 screws used to fasten the Skimo A/C unit on the roof must be
replaced by M8 screws adapted regarding their length and mechanical characteristics.
Electrical power:
The machine or vehicle engine must be equipped with a 80V DC voltage source (battery) able to supply the
electrical power required from the Skimo A/C unit. The Skimo A/C unit maximal consumption is 960W
(12Amps @ 80V) for the compressor power and 140W (12A @ 12VDC or 6A @ 24VDC) for the accessories
(blower, condenser fan).
Roof and ceiling:
Do not alter or make a hole in the cabin of vehicles that are certified « FOPS-ROPS »
The roof must be stiff and strong enough for the Skimo A/C unit to be installed on. If it is not the case, the
roof must be reinforced.
The Skimo A/C unit must not be installed if it would affect the stability of the vehicle or machine it is
installed on, or if it would create excessive strains on its structure.
Make sure using the drawing showing the dimensions of the unit and the cut-out area that there is enough
space to fit the unit on the roof and the cabin panel inside the cabin.
The surface on which the Skimo A/C unit is installed must be flat and horizontal (± 5°).
The cabin panel must be installed inside the cabin, and the user must be able to access the controls from
his driving position while using the vehicle or machine.

10. ELECTRICAL CONNECTION
There are two possible ways to lay out the electrical cables:
- Inside the cabin (recommended), through one of the cabin frame post for example.
- Outside the cabin.
In both cases the installer must make sure that the cables are insulated and protected from any risk
of deterioration or tear-up (from branches for example) and that they do not present any risk for people or
appliances.
10.a Case of the cables being laid out inside the cabin:
1. Remove the grommet at the bottom
of the black evaporator casing
2. make a hole in the grommet and
insert
the cables through it.
3. Insert the cables in the hole from
which you removed
the grommet, ease
them out inside the cabin through the
unit air intake cut out, and set the
grommet back in place. Make sure the
grommet is waterproof
10.b Case of the cables being laid out outside the cabin:
Make a hole on the white outer Skimo casing (the lower part), lay the cable out through this hole with a grommet.
Do not lay the cables out near the m oto r and compressor belt located at th e back of the unit.

13 SKIMO A/C UNIT USE
The Skimo A/C unit is designed to run only when there is a +12V (320 B12) /+24V (320B17) volta ge
on the D+ (ENABLE) contact. This can be for example used wi th a battery discharge protection sys tem
(driver presence, battery charge level, timer, …).
The ability of the Skimo A/C unit to maintain the required temperature inside the cabin depends on the amount of
heat that penetrates inside the cabin. Some preventive measures are necessary to lower the amount of heat that enters
the cabin and to improve the performances of the Skimo A/C unit:
- Park the machine or the vehicle in the shade.
- Drive for a few minutes with the windows opened to lower the temperature inside the cabin before turning the
A/C unit on.
- Keep the doors and windows closed while using the A/C unit.
- Avoid using devices that produce heat.
Operating modes:
- Once the Skimo A/C unit is installed and the vehicle’s engine is running, turn the control panel ventilation speed selector
switch to first speed to turn the unit on. The first ventilation speed and the air conditioning are turned on.
- Adjust the ventilation speed to 1, 2 or 3 according to your requirement with the ventilation speed selector switch.
- To switch the unit off, turn the ventilation speed selector switch to 0.
Switch the Skimo A/C unit off if the vehicle’s or machine’s engine runs o n low speed for an extended amount of
time (for over 15 minutes). If not, there is a potential risk of battery disc harge due to the fact that the alternator might
not supply enough power when the engine runs at low speed. The Skimo A/C unit would turn to security mode. If that
happens, refer to section 14.
It is normal for the internal thermostat to regulate the A/C unit if the blowing temperature is too low, in which case
the blowers still run but the air conditioning is turned off for a while.
SNDC SAS cannot be held responsible for condensation appearing on the cabin’s surfaces. The air contains moisture
that tends to condensates on cold surfaces. Appropriate cabin insulation can prevent or lover the risks of condensation.
14 REPAIRS
If the A/C circuit hasn’t got the correct amount of gas, the performances of the A/C system will lower. If it seems
that your Skimo A/C unit doesn’t work properly, you should take it to an A/C specialist.
Never try to repair faul ts by your own means. Repair and rec harge of an A/C circuit must be carried
out by a specialist that is qualified, certified, equipped with necessary tools and that will use or iginal spare
parts.
If one of the security systems is activated, the air conditioning system is turned off (no more cold
production) and the default light is switched on on the control panel.
To reset the Skimo A/C unit after a security cut off, turn it off and on again. A security cut off should
not be a recurring feature. In the case of repeated cut offs, contact your qualified specialist.

Harness 274B78 is made up of 5 cables. A white cable (D+), a grey cable (+80V), a red cable (+12V), a black cable
(GND 12 V) and a matt black cable (GND 80V).
In one side of this harness, there are two connectors: a two way white FASTON connector and a four way grey DEUTSCH
connector.
Fig 6
In the other side are 5 free cables.
Fig 7
Step 1 :
Cut the cables to the appropriate length. The grey and matt black cables (cable 1 and cable 2) will be connected to the
80V power supply and that the red and black cables will be linked to the 80V->12V converter. Provide two cables: a grey
one and a matt black one (H07-VK or H07-VR) (cable 3 and cable 4) that will go from the power supply (80V) to the
converter. You can reuse if possible the cables cut out previously. See fig 8.
Step 2 :
Once the grey and matt black cables (cables 1, 2, 3, 4) are at the appropriate length, crimp on the free side the matching
electrical terminals so that they can be connected to the power supply (80V). You will find in the accessories bag
different size of terminals. Cables 1 and 3 go to “+80V” and cables 2 and 4 to “GND 80V”.
Step 3 :
On the free side of cables 3 and 4, crimp figure 3 sockets on them. Now, on the free side of the red and black cables
(cables 5 and 6), crimp the same sockets and mount them in the same connector, the one going to the converter.

Step 4:
On the free side of the white cable crimp the appropriate terminal. This cable will be connected to the D+ signal of the
alternator.
Step 5 :
See point 10: Electrical connection
This step consists in connecting the 4 way connector and the two way connector to the SKIMO unit.
