Before commissioning
Initial commissioning
It is recommended that initial commissioning be
carried out by a REMKO service technician or a
technician authorised by REMKO. We also recom-
mend that you complete the commissioning report
and send it to REMKO by post or e-mail within
eight days. In addition, the following requirements
for commissioning must be met.
NOTICE!
Before commissioning, the complete system
hydraulics must be flushed and filled in accord-
ance with standards. If a drinking water storage
tank is installed, this must likewise be filled
before commissioning.
Heating system
n
Fill the heating system with demineralised
water in accordance with VDI 2035. We recom-
mend the addition of REMKO full heating pro-
tection.
n
Flush, clean and bleed the entire heating
system (incl. hydraulic adjustment).
n
To determine possible pressure loss, perform a
pressure test. Eliminate leaks to prevent
oxygen from entering the piping system.
n
Adjust the pre-pressure in the expansion
vessel to the static pressure of the system.
n
The type of design and the static height of the
system determine the operating pressure. The
pressure can be read off the pressure gauge.
n
Make sure that all valves of the heating system
and the distributors are open to guarantee the
free medium flow rate.
n
Check the direction of flow of the heating cycle
(indicated on the heat pump).
Source system (brine-water closed system)
n
To determine possible pressure loss, perform a
pressure test. Eliminate leaks to prevent
oxygen from entering the piping system.
n
Adjust the pre-pressure in the expansion
vessel to the static pressure of the system.
n
Fill the source system completely with brine
(water with antifreeze concentration of at least
25%) and bleed it.
n
The type of design and the static height of the
system determine the operating pressure. The
pressure can be read off the pressure gauge.
n
Make sure that all valves of the source system
and the distributors are open to guarantee the
free medium flow rate.
n
Check the direction of flow of the source
system (indicated on the heat pump).
Source system (water-water system)
n
Perform a leak test of the system.
n
Ensure that the underwater pump or another
pump is pumping water. In some cases the
source pump must be bled and filled with
water.
n
Make sure that all valves of the source system
and the distributors are open to guarantee the
free medium flow rate.
n
Check the direction of flow of the source
system (indicated on the heat pump).
