2 About the box

2.1 Outdoor unit

2.1.1 To remove the accessories from the outdoor unit

1 Open the outdoor unit.

INFORMATION

The instruction sheet for valve kit EKMBHBP1 only applies
in case valve kit EKMBHBP1 is part of the system. If so, do
NOT take into account the instruction sheet delivered with
the valve kit; it is overruled by the one delivered with the
outdoor unit.

3 Preparation

3.1 Preparing installation site

3.1.1 Installation site requirements of the outdoor unit

Mind the following spacing guidelines:

a Air outlet
b Air inlet

INFORMATION

If shut-off valves are installed on the unit, provide a
minimum space of 400mm at the air inlet side. If shut‑off
valves are NOT installed on the unit, provide a minimum
space of 250mm.

Do NOT install the unit in sound sensitive areas (e.g. near a
bedroom), so that the operation noise will cause no trouble.

Note: If the sound is measured under actual installation conditions,
the measured value might be higher than the sound pressure level
mentioned in "Sound spectrum" in the data book due to
environmental noise and sound reflections.

2 Remove the accessories.

Minimum flow rate

Check that the minimum flow rate (required during defrost/backup
heater operation) in the installation is guaranteed in all conditions.

NOTICE

If glycol was added to the water circuit, and the
temperature of the water circuit is low, the flow rate will
NOT be displayed on the user interface. In this case, the
minimum flow rate can be checked by way of the pump
test (check that the user interface does NOT display error
7H).

NOTICE

When circulation in each or certain space heating loops is
controlled by remotely controlled valves, it is important that
the minimum flow rate is guaranteed, even if all valves are
closed. In case the minimum flow rate cannot be reached,
a flow error 7H will be generated (no heating/operation).

See the installer reference guide for more information.

4.3 Connecting the water piping

4.3.1 To connect the water piping

NOTICE

Do NOT use excessive force when connecting the piping.
Deformation of the piping can cause malfunctioning of the
unit. Make sure that the tightening torque does NOT
exceed 30N•m.

To facilitate service and maintenance, 2 shut-off valves are provided.
Mount the valves on the water inlet and water outlet. Mind their
position: the integrated drain valves will only drain the side of the
circuit on which they are located. To be able to only drain the unit,
make sure the drain valves are positioned between the shut‑off
valves and the unit.

Heater tape (field supply)

1 Install heater tape to the outdoor field piping.
2 Provide external power supply for the heater tape.

NOTICE

▪ For the internal heater tape to operate, the power to the

unit MUST be ON. For this reason, during cold periods,
never disconnect the power, nor turn off the main
switch.

▪ In case of a power failure, power to the heater tape

(both internal and external) will be aborted and the
water circuit will NOT be protected. To guarantee a full
protection, it is always possible to add glycol to the
water circuit, even when installing heater tape to the
outdoor field piping.

Glycol

The required concentration of glycol depends on the lowest
expected outdoor temperature, and on whether you want to protect
the system from bursting or from freezing. To prevent the system
from freezing, more glycol is required. Add glycol according to the
table below.

INFORMATION

▪ Protection against bursting: the glycol will prevent the

piping from bursting, but NOT the liquid inside the
piping from freezing.

▪ Protection against freezing: the glycol will prevent the

liquid inside the piping from freezing.

b Water outlet

1 Screw the outdoor unit nuts on the shut-off valves.
2 Connect the field piping on the shut-off valves.

NOTICE

Install a manometer in the system.

NOTICE

Install air purge valves at all local high points.

4.3.2 To protect the water circuit against freezing

Frost can damage the system. For this reason, if negative ambient
temperatures are expected, make sure the water circuit is sufficiently
protected against freezing. Freeze protection is model-dependent.
Either add glycol to the water circuit, or provide the outdoor field
piping with heater tape, according to the table below.

If … … then

Standard model (no -H- in the
model name)

Heater tape model (-H- in the
model name)

Add glycol to the water circuit,
according to the instructions
below. In this way, you protect
the internal water piping, as well
as the outdoor field piping.

The internal water piping is
factory‑equipped with heater
tape and additional insulation,
this to prevent it from freezing.
To prevent the outdoor field
piping from freezing, provide it
with sufficient insulation or heater
tape (field supply), according to
the instructions below.

Lowest expected
outdoor
temperature

–5°C 10% 15%
–10°C 15% 25%
–15°C 20% 35%

NOTICE

▪ It is the responsibility of the installer to add the correct

glycol percentage, depending on the expected ambient
temperatures.

▪ The addition of glycol applies to BOTH cooling‑only

models (EWAQ004+005BAVP) AND reversible models
(EWYQ004+005BAVP), and is independent of cooling
or heating operation.

▪ The required concentration might differ depending on

the type of glycol. ALWAYS compare the requirements
from the table above with the specifications provided by
the glycol manufacturer. If necessary, meet the
requirements set by the glycol manufacturer.

▪ The added concentration of glycol should NEVER

exceed 35%.

▪ If the liquid in the system is frozen, the pump will NOT

be able to start. Mind that if you only prevent the
system from bursting, the liquid inside might still freeze.

▪ In case of a power supply failure or pump failure, and

NO glycol was added to the system, drain the system.

▪ When water is at standstill inside the system, the

system is very likely to freeze and get damaged.

The following types of glycol are allowed:
▪ Ethylene glycol;
▪ Propylene glycol, including the necessary inhibitors, classified as

CategoryIII according to EN1717.

WARNING

Ethylene glycol is toxic.

NOTICE

Glycol absorbs water from its environment. Therefore do
NOT add glycol that has been exposed to air. Leaving the
cap off the glycol container causes the concentration of
water to increase. The glycol concentration is then lower
than assumed. As a result, the hydraulic components
might freeze up after all. Take preventive actions to ensure
a minimal exposure of the glycol to air.

NOTICE

▪ If overpressure occurs, the system will release some of

the liquid through the pressure relief valve. If glycol was
added to the system, take adequate measures so as to
safely recover it.

▪ In any case, make sure that the flexible hose of the

pressure relief valve is ALWAYS free to release
pressure. Prevent water from staying and/or freezing
up inside the hose.

WARNING

Due to presence of glycol, corrosion of the system is
possible. Uninhibited glycol will turn acidic under the
influence of oxygen. This process is accelerated by the
presence of copper and high temperatures. The acidic
uninhibited glycol attacks metal surfaces and forms
galvanic corrosion cells that cause severe damage to the
system. Therefore it is important that:

▪ the water treatment is correctly executed by a qualified

water specialist,

▪ a glycol with corrosion inhibitors is selected to

counteract acids formed by the oxidation of glycols,

▪ no automotive glycol is used because their corrosion

inhibitors have a limited lifetime and contain silicates
which can foul or plug the system,

▪ galvanized pipes are NOT used in glycol systems since

the presence may lead to the precipitation of certain
components in the glycol's corrosion inhibitor.

Adding glycol to the water circuit reduces the maximum allowed
water volume of the system. For more information, refer to the
chapter "To check the water volume and flow rate" in the installer
reference guide.

3 If an automatic air purge valve was installed, make sure it is

open.

4 Fill the circuit with water until the manometer (field supply)

indicates a pressure of ±2.0bar.

5 Purge as much air as possible from the water circuit. For

instructions, see "6Commissioning"on page17.

6 Refill the circuit until the pressure is ±2.0bar.
7 Repeat steps 5 and 6 until no more air is purged and there are

no more pressure drops.

8 Close the drain and fill valve.
9 Disconnect the water supply hose from the drain and fill valve.

4.3.4 To insulate the water piping

The piping in the complete water circuit MUST be insulated to
prevent condensation during cooling operation and reduction of the
heating and cooling capacity.

To prevent the freezing of the outdoor water piping during winter
time, the thickness of the sealing material MUST be at least 13mm
(with λ=0.039W/mK).

If the temperature is higher than 30°C and the humidity is higher
than RH 80%, the thickness of the insulation materials should be at
least 20 mm to prevent condensation on the surface of the
insulation.

During winter, protect the water piping and shut‑off valves against
freezing by adding heat tape (field supply). If the outdoor
temperature can drop below –20°C and no heat tape is used, it is
recommended to install the shut‑off valves indoors.
