Adding refrigerant

The units contain a basic

quantity of refrigerant. Should

the refrigerant leak, remedy

the leak, pump the refrigerant

pipes down to a vacuum and reﬁll

the basic quantity of refrigerant.

Refrigerant ﬁll

quantity BL 261 BL 351

Basic

line length 0.7 kg 1.0 kg

Following a successful leak check,

the unit can be started again

without the pipes needing to be

pumped down to a vacuum.

Perform the following checks

prior to commissioning the unit

for the ﬁrst time and after any

interventions affecting the cooling

circuit. Record the results in the

commissioning report:

■

Check and open shut-off valves

■

Check all refrigerant pipes and

valves using leak detection

spray or soapy water to ensure

they are tight and that the

suction and injection pipes have

not been accidentally confused

with the unit at a standstill.

■

Check the refrigerant lines and

insulation for damage.

■

Check the electrical connection

between the indoor unit and

the outdoor component for

correct polarity.

■

Check that all fastenings,

mountings etc. are ﬁrm and at

the correct level.

Before

commissioning

When ﬁlling the system with

refrigerant, ensure that it is

always in liquid form!

! ATTENTION

NOTE

Check overheating to

determine the refrigerant ﬁll

quantity.

Wear protective clothing when

handling refrigerant.

! ATTENTION

Commissioning

Commissioning should only be

performed and documented

by specially trained personnel.

NOTE

The system can be commissioned

once all the components have

been connected and tested.

A functional check should be

performed to verify its correct

function and identify any unusual

operational behaviour prior to

handing it over to the operator.

Functional checks and

test run

Check the following points:

■

Leak tightness of refrigerant

pipes.

■

Compressor and fan running

smoothly.

■

In cooling mode, cold air

output by the indoor unit, and

warm air output by the outdoor

component.

■

Functional test of the indoor

unit and all program sequences.

■

Check of the surface

temperature of the suction

line and check vaporiser is

not overheating. To measure

the temperature, hold the

thermometer to the suction

line and subtract the boiling

point temperature reading on

the pressure gauge from the

measured temperature.

■

Record the measured

temperatures in the

commissioning report.

NOTE

The escape of refrigerant con-

tributes to climatic change. In

the event of escape, refrigerant

with a low greenhouse poten-

tial has a lesser impact on glo-

bal warming than those with a

high greenhouse potential.

This device contains refrige-

rant with a greenhouse poten-

tial of 1975. That means the

escape of 1 kg of this refrige-

rant has an effect on global

warming that is 1975 times

greater than 1 kg CO2, based

on 100 years. Do not conduct

any work on the refrigerant

circuit or dismantle the de-

vice - always enlist the help of

qualiﬁed experts.
