REMKO CMF-80 v.2 - Manual (Page 15)

■ It is to be ensured that a gate
valve is positioned upstream
and downstream of the dirt
traps. This ensures that the dirt
traps can be checked at any
time without loosing water.
■ The dirt traps must be checked
during every service of the sys-
tem.
■ The indoor module contains a
ventilation connection in the
inlet line in order to enable ad-
ditional venting.
It must be ensured that a
suffi cient fl ow-rate is given.

■ All visible metallic surfaces must
be additionally insulated.
■ Cooling mode via the heating
circuit requires a completely
vapour diffusion tight insulation
along the entire length of the
pipework.
■ All outgoing heating circuits
including the connections for
water heating are to be secured
against circulating water by
means of fl ap valves.
■ The system must be fl ushed
before commissioning the sys-
tem. The entire system must be
subjected to a tightness check
and a thorough venting.
Electrical connection
For the CMF and CMT devices, a
mains cable must be laid for both
the outdoor and indoor modules.
In some cases it may also be pos-
sible to feed the power supply
for the indoor module from the
outdoor module. The outdoor
modules of Series CMF 80, CMF
90, CMT 100 require a 230V
mains supply. The outdoor mod-
ules of Series CMF 140, CMF 150
and CMT 150 have to be provided
with a 400 V supply. The electrical
connection between the modules
is realised with a 4-wire control
cable.
A clockwise rotating field must
be ensured for 400 V power
supplies.
CAUTION
The following diagram provides an
overview of the required connec-
tions.
The diameters for the leads and
the connection cables are to be
selected according to local regula-
tions.
The fusing level is to be taken from
the technical data.
It is possible that the energy sup-
ply company will provide a special
power supply tariff for the opera-
tion of heat pumps.
Individual tariff options should be
agreed with the local energy sup-
ply company.
Check all plugged and clamped
terminals to verify they are
seated correctly and making a
permanent contact. Re-tighten
as required.
