7 Installation

The evaporator unit must be installed in an upright position. Fig. 2 on page 2

The parking cooler consists of the following components:

• CoolAir SPX 1200C compressor unit (2)
• CoolAir SPX 1200IC rear panel evaporator unit (1) with connecting line (3)

Fig. 3 on page 2

The compressor unit (2) is attached to the firm and straight rear panel of the cab or by means of a firm fastening frame. The evaporator unit (1) is fitted on the inside of the rear panel of the cab.

Note
The connection line (3) can only be installed after fitting the evaporator unit and the compressor unit.

Notes on the installation

WARNING! Danger of electrocution

• Detach all connections to battery before starting the installation of the parking cooler.
• Ensure that all electrical components are electrically discharged before carrying out work on them.

CAUTION! Risk of injury
Improper installation of the air conditioning roof unit puts the safety of the user at risk and can result in irreparable damage to the device.

The manufacturer strongly recommends the use of a vehicle-specific fastening frame for an best installation procedure for the SPX 1200C compressor unit on the rear panel of the cab. Following installation of the unit, the specified unit software parameters must then be checked. Observe the following tips and information when installing the parking cooler:

1. Consult the vehicle manufacturer on 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?

2. Check the dimensions of the unit (Fig. 2).

3. 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.

4. Avoid any narrow radius 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 parking cooler from operating. 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.
   Fig. 4 on page 3

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

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

7. The device can be connected directly to the battery or via the lorry’s terminal block. The battery is preferred for the connection. On some vehicles larger consumers connected to the terminal block are switched off after a short while if the power requirement is too high. Ask your vehicle manufacturer for the specifications of the terminal block.

8. Follow the vehicle manufacturer’s guidelines when installing the system and establishing the electrical connections.

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

Determining the installation position

The system’s installation position must meet the following criteria:

• All maintenance work must be easy to perform.
• Sufficient space must be available for the refrigerant line.
• The refrigerant line must be long enough (approx. 2.1 m) for connection of the condenser and evaporator unit. The line must not be routed under tension (Fig. 3).
• The fastening surface should be as flat as possible. Use spacer sleeves for uneven surfaces. If spacer sleeves are used, appropriately longer fastening screws with sufficient tensile strength (not included in the assembly set) must then be used.

Note

The fastening screws M6 x 40 mm included are designed for use with the spacer sleeves, l = 25 mm, (e.g. MAN TGX).

The fastening screws M6 x 110 mm included are designed for use with the spacer sleeves, l = 40 mm, (e.g. Volvo FH as of construction year 2013) (two spacer sleeves for each screw).

By combining the spacer sleeves, different distances between the rear wall of the cab and inner trim can be achieved.

The screw overhang beyond the nut must not exceed 15 mm.

If spacer sleeves are not to be used or if other ones are to be used, the fastening screws have to then be adapted to match them. Otherwise the device housing may be damaged.

Installing the evaporator unit

The evaporator unit is fitted horizontally on the cab’s rear panel, near the bunk.

1. NOTICE! Damage hazard
   •  Ensure that the drill template included is not upside down when positioned. You can position the drill template from the inside or from the outside onto the cab.
   •  Ensure that the following holes are used for the connecting and condensation line: From inside: Holes that bear the inscription “Inside” From outside: Holes that bear the inscription “Outside”
   Find a suitable fastening position in the cab that allows sufficient air circulation.

2. Drill the holes for mounting the evaporator unit.
   Fig. 5 on page 4

3. Drill the hole for the connection line (Ø 50 mm).
   Fig. 6 on page 5

4. Drill the holes for the condensation line (Ø 18 mm).

5. NOTICE! Damage hazard
   Ensure that the coupling halves with the copper pipes are not twisted or kinked.
   Carefully unwind the connection line.
   Fig.7 on page 5

6. Fit the evaporator unit. Fig. on page 6

7. Fasten the evaporator unit from the outside. Fig. on page 7

Sealing and attaching the hood

1. Mount one clip. If you wish to avoid damaging the cab’s rear panel (drilling a hole), you can also fix the hood in place using a suitable adhesive. Observe the instructions provided by the adhesive manufacturer.
2. Mount the hood. Fig. 10 on page 8

Routing the supply lines to the compressor unit

Observe the following notes when routing the supply lines:

• The installation manual for the SPX 1200C compressor unit should also be observed.
• Mount the SPX 1200C compressor unit first to enable the exact position of the compressor unit to be determined. This will save you bending the copper pipe several times to make it fit.
• Ensure that the maximum length of the supply lines does not exceed 2.1 m.
• To avoid damaging the cab’s rear panel fix the clip in place using a suitable adhesive. Observe the instructions provided by the adhesive manufacturer.

1. Shorten any supply line which is not needed by bending a curve.
2. Fasten the supply lines to the cab’s rear panel using the clips.
   Fig. 11 on page 9

Connecting the compressor unit to the evaporator unit

1. Route the connection cable in a curve out through the opening in the floor of the compressor unit.
2. Fasten the connection cable as shown.
   Fig. 12 on page 10
   Fig. 13 on page 11

Installing the electrical connection lines

1. Connect the unit directly to the battery.
   Ask your vehicle manufacturer for the specifications of the battery.

2. Route the power supply lead as illustrated.
   Fig. 14 on page 12
   a) Run the wiring loom to the battery along a route where it is protected.
   b) Connect the negative lead (black) for the power supply.
   c) Connect the negative lead (black) for the voltage monitor.
   d) Connect the positive lead (red) for the power supply via a 40 A fuse.
   e) Connect the positive lead (red) for the voltage monitor via a 2 A fuse.

8 Configuration

Before the system is first put into operation, the control unit settings can be adjusted to suit the various installation conditions Fig. 15. Those adjustments must be made by the installer.

The configuration mode can still be activated if the low voltage cut-out has switched off the system and only residual voltage is available. Fig. 15 on page 13

Using the configuration mode

P.01: Low voltage shut-down

The battery monitor protects the battery against discharging excessively.

If the unit is switched off by the battery monitor, it means the battery charge level is low. Avoid repeated starting or using electrical equipment. Ensure that the battery is recharged. As soon as the required voltage is available again, the system can be operated again.

If only the power supply voltage specified here is available to the parking cooler, the system is switched off.

P.02: Unit for temperature display

P.05: Tilt sensor

The electronics of the system prevents that the system is switched on when the vehicle is parked at a slope. Since some vehicles` roof already is tilted, the tilt sensor has to be calibrated to the zero setting before first use.
