NOTE

• The manufacturer strongly recommends the use of a vehicle-specific fastening frame for an optimum installation procedure for the compressor unit on the rear panel of the cab.
• After installing the unit, the specified parameters of the unit software must be checked (refer to the installation instructions of the evaporator unit).

You should always read this installation manual all the way through before installing the parking cooler.
You should always observe the following tips and information when installing the parking cooler:

• Please consult the manufacturer of your vehicle with regard to the following. ­
  – is the cab’s rear panel a suitable location for attaching the unit? ­
  – is the body designed to bear the static weight and loads occasioned by the parking cooler in a moving vehicle?

• Always check before installation of the unit whether any vehicle components could be damaged, deformed or impaired in terms of their functionality as a result of the installation.

• Avoid any unnecessary and frequent mechanical stress to the supply line between the evaporator unit and the compressor unit. Damage can result in the loss of refrigerant and impair the performance of the unit.

• The supplied assembly parts must not be modified during installation.

• The ventilation slots (grill) may not be covered (minimum distance from other attachment parts: 10 cm).

• If a fastening frame is not used to install the system, make sure that the installation position of the compressor unit on the rear panel is not too low. The system could be damaged by high temperatures of the engine’s waste heat.

• The device shall be installed in accordance with national wiring regulations.

6.3 Determining the installation position
The installation position of the unit must meet the following criteria:

• All maintenance work must be easy to perform.

• Sufficient space must be available for the refrigerant line.

• The compressor unit must not be installed with a horizontal or vertical inclination.

• The compressor unit must not be fitted near direct waste heat (engine heat etc.).

• The refrigerant line must be long enough to connect the compressor and evaporator units. The line must not be laid taut. ­
  – SP950T/SPX1200T: approx. 4.2 m ­
  – SP950I: approx. 2.3 m ­
  – SPX1200IC: approx. 2.1 m

• The fastening surface should be as flat as possible. Use spacer sleeves for uneven surfaces. If spacer sleeves are used, longer fastening screws with sufficient tensile strength (not included in the assembly set) must be used.

• The freedom of movement of semi-trailers (of the outer edges of the semitrailer when turning or jackknifing) and other vehicle attachments must not be restricted.

6.4 Installing the compressor unit
NOTICE! Damage hazard
Due to its weight, the compressor unit must have contact with at least two fastening points of the fastening surface. Do not use spacer sleeves for all four fastening points.
NOTE
To install the compressor unit using a vehicle-specific fastening frame, please observe the instructions included in the frame’s scope of delivery. The following work steps describe the installation of the compressor unit without vehicle-specific fastening frame.
Overview: fig. 2

• Dismantle the outer housing.
  SP950C: To do this, remove the four hexagon bolts on the fan (fig . 3

1. and the eight hexagon socket head bolts (fig .3 2).
   When taking off the outer housing, release the plug connection of the fan connection cable.
   SPX1200C: To do this, remove the six torx screws (fig. 4 1).

• Decide on the position of the compressor unit. Use the fastening holes of the compressor unit as a template.

• Use a felt pen to mark the positions selected for the holes.

• Drill fastening holes (Ø 9 mm) at the marked positions.
  NOTE Apply anti-oxidant compound to all drilled through-holes to prevent rust formation.

• Push the four M8 x 40 mm bolts (fig. 5 10) with the four washers outer diameter Ø 40 mm (fig. 5 9) from the inside through the rear wall.

• From the outside, push the four washers (fig. 5 8) on the protruding bolts.

• Fasten the bolts and washers using the narrow M8 nuts (fig. 5 7).

• Push the washers (fig. 6 6) on the protruding M8 bolts. For rear walls with an offset, use the supplied spacer sleeves (fig. 6 5) to compensate. Adjust the length.

• Put the compressor unit on the protruding M8 bolts.

• Fasten with the M8 washers (fig. 6 4) and the M8 self-locking nuts (fig. 6 3).

NOTE The panelling can only be fitted once the refrigerant lines and the cables (chapter “Connecting the compressor unit to the evaporator unit” on page 11) have been connected.
6.5 Connecting the compressor unit to the evaporator unit
NOTICE! Damage hazard
Before fastening the connection couplings, make sure that the sealing and thread faces are absolutely clean. Any contamination will result in a malfunction of the air conditioner.
Install the connection line for the compressor unit and insert it in the compressor unit.
**** NOTE Make sure that the coupling half with the thin capillary tube is not twisted or kinked. When tightening the coupling halves, it is essential that you use a second openended spanner to hold the other part.

• Connect the rear coupling halves (thick refrigerant line) (fig. 7) with each other and tighten them hand-tight ¼ revolution with an open-ended spanner.

• Connect the front coupling halves (thin refrigerant line) (fig. 8) with each other and tighten them hand-tight ¼ revolution with an open-ended spanner.

• SP950C only: Install the protective cover underneath the coupling and secure it with the lid supplied.

• SP950C only: Fasten the thick refrigerant line with the supplied pipe clip, the M6 x 16 mm hexagon head bolt, the M6 washer and the M6 self-locking nuts (fig. 9).

• SPX1200C only: Assemble the refrigerant line as shown (fig. 0).
  Observe the following instructions when installing the supply lines:

• Also observe the installation instructions for the evaporator unit.

• The maximum cable length between the evaporator and compressor unit is:
  – SP950T/SPX1200T: approx. 4.2 m ­
  – SP950I: approx. 2.3 m ­
  – SPX1200IC: approx. 2.1 m

• Avoid any narrow radii when routing and bending supply lines. Use a suitable round object with a shim as a bending aid. A radius which is too narrow will kink the refrigerant line, and this will prevent the auxiliary air conditioning unit from operating.

• Shorten any supply line which is not needed by bending a curve.

• SP950C only: Insert the plug of the cable (power cable) into the mating plug of the compressor unit (fig. a).

• SPX1200C only: Assemble the connection cable and corrugated piping as shown (fig. 0 and fig. b).

• SP950C only: Insert the plug connection of the fan cable back together. Place the outer housing onto the compressor unit.

• SP950C only: Fasten the outer housing with the eight hexagon socket screws (fig. c 2).

• SP950C only: Fasten the fan with the four hexagon bolts (fig. c 1).

• SPX1200C only: Fasten the outer housing with the six torx screws (fig. 0).

• Apply sealant (fig. e 1) to prevent any water from getting between the rear wall of the truck and the clip.

NOTE If you want to avoid damaging the rear wall of the truck (drilling a hole), you can also apply the clip using a suitable adhesive. Observe the instructions provided by the adhesive manufacturer.

• Use the supplied holders to fasten the connection line to the rear panel of the truck (fig. e).
• Insert corrugated piping in the holder provided (fig. e 2).
• Put on the lid (fig. e 4).
