Preparation for installation

 

 

 

2.  Preparation for installation 

2.1.  Safety instructions 

  The safety instructions outlined on pages 3 and 4 must be read 

and noted before starting work. 

  Installation should be performed by someone well versed in auto 

mechanics/auto electrics. 

2.2.  Conditions for assembly 

  Before assembling and operating the air-conditioning system(s), 

the vehicle's power supply must be checked for sufficient capacity, 

and must be upgraded if necessary. 

  A free generator capacity of 65 A (max. current consumption per 

unit) must be at disposal per unit to be constructed. This capacity 

must be guaranteed at idle speed, and at the same time at 

maximum engine compartment temperature (low speed and high 

ambient temperature diminish the output of generators). 

 

 

 

 

 

 

2.3.  Preparations on vehicle’s roof 

 

When working on the bus roof or on any hoisting equipment, 

scaffolding etc. suitable safety precautions must be taken to 

prevent falls. 

 

Wear protective gloves! 

2.4.  Roof cut-outs 

The required roof cut-outs (opening for refrigerant connection and 

electrical interfacing) must be clearly indicated on the roof. Make 

the roof cut-out using suitable tools. Cut edges should be deburred 

and protected against corrosion. 

NOTE: 

Interface drawings can be obtained from Spheros! 

Warning! 

Danger of severe injuries or 

fatal fall! 

Caution! 

Danger of cut injuries due to 

sharp metal edges!
