Protecting the water circuit against freezing
Frost can damage the unit. For this reason, in colder climates the
water circuit must be protected by means of a heater tape or by
adding glycol to the water.
In case of heater tape
1 Check that the unit has the option heater tape installed.
(Connections of the factory mounted heater tape are made on
terminals 6/7 inside the switch box).
2 Install a heater tape (field supply) on the outdoor field piping.
Power supply connections for this heater tape must be made on
terminals 6/7 inside the switch box provided this heater tape is of
a type that consumes not more than 200 W.
In case of glycol
Depending on the expected lowest outdoor temperature, make sure
the water system is filled with a weight concentration of glycol as
mentioned in the table below.
Also refer to "Checks before start-up" on page 10.
Initial start-up at low ambient temperatures
(Heat pump models only)
When ambient temperature is below 5°C in case of fan coil
applications or below 10°C in case of floor heating applications, it is
recommended to fill the water system with a weight concentration of
glycol during intitial start-up. Refer to the table below.
Charging the water
1 Connect the water supply to the drain and fill valves (see "Main
components" on page 3).
2 Fill with water until the manometer indicates a pressure of
approximately 2.0 bar. Remove air in the circuit as much as
possible using the air purge valves.
Piping insulation
The outdoor and indoor part of the water circuit must be insulated to
prevent condensation during cooling operation and reduction of the
cooling and heating capacity.
For the heater tape to operate, power to the unit must
be provided and the main isolator switch must be on.
For this reason never disconnect power and never
turn off the main isolator switch for a long time during
cold periods!
In case this heater tape is of a type that consumes
more than 200 W, this heater tape must be connected
to a separate power supply and not to heater tape
terminals 6/7!
Minimum

0°C –5°C –10°C –15°C
Ethylene glycol 10% 15% 25% 35%
Propylene glycol 10% 15% 25% 35%
Make sure to use an industrially inhibited glycol fluid with
non toxic multi-metal corrosion inhibitors to passivate the
system.
Ethylene glycol 15%
Propylene glycol 15%
Make sure to use an industrially inhibited glycol fluid with
non toxic multi-metal corrosion inhibitors to passivate the
system.
NOTE
To ensure that the unit operates within its operating
range as soon as possible (water temperature >30°C),
the load during start-up must be reduced as much as
possible. You can do this by putting off fans of the fan
coil units until the water temperature has increased
to 30°C.
NOTE
■ During filling, it might not be possible to remove all
air in the system. Remaining air will be removed
through the automatic air purge valves during first
operating hours of the system. Additional filling
with water afterwards might be required.
■ The water pressure indicated on the manometer
will vary depending on the water temperature.
(higher pressure at higher water temperature).
However, at all times water pressure should
remain above 0.3 bar to avoid air entering the
circuit.
■ The unit might dispose some excessive water
through the pressure relief valve.
