Add refrigerant

The equipment contains a basic 

quantity of refrigerant. Beyond 

these conditions, for refrigerant 

pipe lengths of more than 5 meters 

per circuit, an additional amount of 

refrigerant must be added, accord-

ing to the following chart:

RVD 351DC RVD 521DC

Up to and 

incl. 5m

0 g/m

5m to   

max. 15m

25  

g/m

-

5m to   

max. 20m

-

25 g/m

Note that the employed refrig-
erant is always filled in liquid 
form!

      CAUTION

      NOTE

Check the overheating to 
determine the refrigerant fill 
quantity

Wear protective clothing when 
handling refrigerant.

      CAUTION

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 per-

formed to verify its correct func-

tion and identify any unusual 

Function test and 

test run

Check the following points:

■ 

Leak tightness of refrigerant 

pipes.

■ 

Compressor and fan running 

smoothly.

■ 

In cooling mode, cold air should 

be output by the indoor unit, 

and warm air should be output 

by the outdoor component.

■ 

Functional test of the indoor 

unit and all program 

sequences.

■ 

Check of the surface tempera-

ture of the suction pipe and 

determination of vaporiser 

overheating. To measure the 

temperature, hold the ther-

mometer to the suction pipe 

and subtract the boiling point 

temperature reading on the 

pressure gauge from the meas-

ured temperature.

■ 

Record the measured tem-

peratures in the commissioning 

report.

Check that the stop valves and 
valve caps are tight after carrying 
out any work on the refrigerant 
circuit. If necessary, use appropri-
ate sealant products.

      NOTE

Functional test for cooling 

and heating modes

1.  Remove the caps 

from the valves.

2.  Begin the commissioning 

process by briefly opening the 

blocking valves of the external 

section until the manometer 

displays a pressure of approx. 2 

bar.

operational behaviour prior to 

handing it over to the operator.

3.  Use leak detection spray or suit-

able devices to check that all 

the connections are tight.

4.  If no leaks are found, fully open 

the stop valves by turning them 

anti-clockwise using a spanner. 

If leaks are found, repair the 

faulty connection. It is impera-

tive that the vacuum creation 

and drying steps are repeated.

5.  Switch off the main circuit 

breaker or remove the fuse 

(provided by the customer).

6  Press the test knob on the 

outdoor unit and wait until 

a frequency of min. 50 Hz is 

established (only RVD521). 

6.  Use the remote control to 

switch on the unit and select 

the cooling mode, maximum 

fan speed and lowest target 

temperature.

7.  Check the overheating, out-

door, indoor, outlet and vapori-

sation temperatures and record 

the measured values in the 

commissioning report. Check 

the correct function and set-

tings of all regulation, control 

and safety devices.

8.  Check the indoor unit control 

system using the functions 

described in the chapter "Oper-

ation". Timer, temperature set-

ting, fan speeds and switching 

to ventilation or dehumidifying 

mode.

9.  Check the correct function 

of the condensation pipe by 

pouring distilled water into the 

condensation tray. 

A bottle with a spout is recom-

mended for pouring the water 

into the condensation tray.

10. Switch the indoor unit to heat-

ing mode.
