REVO-E Heat pump 1 Introduction
1.6.1 General safety information
Required qualifications
To work on the refrigeration section of the air-condi-
tioning system, proof of both of the following qualifi-
cations is required:
– electrically qualified person (EQP)
EQP: Trained in non-electrical work on/near high-
voltage systems, knows the dangers, does not work
independently (supervision and controls), trained ac-
cording to DGUV 200-005 (old BGI 8686)
– Specialists trained in refrigeration technology with cer-
tificate of competence pursuant to Directive (EC) no.
307/2008
To work on the high-voltage section of the air-condi-
tioning system, proof of both of the following qualifi-
cations is required:
– Electrician for HV systems in powered vehicles Voca-
tional education, job of repeating character, training
pursuant to DGUV 200-005 (old BGI 8686)
– Specialists trained in refrigeration technology with cer-
tificate of competence pursuant to Directive (EC) no.
307/2008
NOTE:
The conditions of these rules are valid within the jurisdic-
tion of DGUV (German Social Accident Insurance) and
must be followed even in countries without special provi-
sions.
Know and follow the operating and servicing instruction
for the systems, tools and aids used as well as their
accompanying safety information from the manufacturer
when evacuating and filling the air-conditioning system.
Working on the bus roof
When working on the bus roof or hydraulic lifts, scaf-
folding, etc, take suitable measures to prevent falling.
1.6.2 Working with high-voltage air-
conditioning systems
Only conduct installation, maintenance and repair
work if the motor is still and the 24V DC power supply
as well as the high-voltage has been switched off.
Before starting work on the air-conditioning system,
ensure that the system is voltage-free and make sure
it remains so for the duration of the work.
In certain cases, the following safety rules must be
followed:
–
make the system voltage-free
– ensure that the system cannot be reactivated
– check whether the system is voltage-free
– ground and short-circuit
– cover or block off neighboring voltage-carrying
parts
Electrical work may only commence if protective
measures against electrical shock, short-circuits and
electric arcs have been taken.
1.6.3 Working with refrigerants
Observe EN 378 when working on cooling systems. There
is an info data sheet or material sheet (available from
manufacturer) for each refrigerant as well as the general
information from professional organizations within the
chemical industry.
Certain conditions apply, that must be maintained, for the
safe and proper use of refrigerants:
–
Wear protective eye wear when working with refriger-
ants. If a refrigerant gets into the eye, serious frostbite
damage may occur. Thoroughly rinse the eyes with
water immediately and seek medical attention.
– Wear protective gloves when working with refriger-
ants. Liquids refrigerant is not to come into contact
with the skin. The hands must be protected from frost-
bite (leaking R 134a condenses at -26.5°C) and from
erosion to the skin's protective layer (refrigerants dis-
solve fat)! If a refrigerant comes into contact with the
skin, thoroughly rinse the point of contact with water
immediately and seek medical attention.
