Installation manual

Mounting the unit
1 Check the strength and level of the installation ground so that
the unit will not cause any operating vibration or noise after
installation.
2 Make sure that the unit is installed level.
3 Prepare 4 sets of M8 or M10 foundation bolts, nuts and washers
each (field supply).
4 Fix the unit securely by means of the foundation bolts in
accordance with the installation drawing.
Screw in the foundation bolts until their length remains 20 mm
above the foundation surface.
Drain work
If drain work is necessary, follow the guidelines below.
■ Two drain outlets are provided in the bottom plate of unit, see
"Unit installation drawing" on page 4 (drain plug and drain hose
are field supply).
■ In cold areas, do not use a drain hose with the unit. Otherwise,
drain water may freeze and block the drain. In case the use of a
drain hose is unavoidable for one reason or another, it is
recommended to install a heater tape in order to protect drain
from freezing.
Water pipework
Checking the water circuit
The units have a water inlet and water outlet for connection to a water
circuit. This circuit must be provided by a licensed technician and
must comply with all relevant European and national regulations.
Before continuing the installation of the unit, beware of the following
points:
■ Two shut-off valves are delivered with the unit. To facilitate
service and maintenance, install one at the water inlet and one
at the water outlet of the unit.
■ Drain taps must be provided at all low points of the system to
permit complete drainage of the circuit. Two drain valves are
provided inside the unit.
■ Air vents must be provided at all high points of the system. The
vents should be located at points which are easily accessible for
servicing. An automatic air purge is provided inside the unit.
Check that this air purge valve is not tightened too much so that
automatic release of air in the water circuit remains possible.
■ Take care that the components installed in the field piping can
withstand the water pressure.
Checking the water volume and expansion
vessel pre-pressure
The unit is equipped with an expansion vessel of 6 litre which has a
default pre-pressure of 1 bar.
To assure proper operation of the unit, the pre-pressure of the
expansion vessel might need to be adjusted and the minimum and
maximum water volume must be checked.
1 Check that the total water volume in the installation is 10 l
minimum:
2 Using the table below, determine if the expansion vessel pre-
pressure requires adjustment.
3 Using the table and instructions below, determine if the total
water volume in the installation is below the maximum allowed
water volume.
Calculating the pre-pressure of the expansion vessel
The pre-pressure (Pg) to be set depends on the maximum
installation height difference (H) and is calculated as below:
Pg=(H/10+0.3) bar
The unit is only to be used in a closed water system.
Application in an open water circuit can lead to excessive
corrosion of the water piping.

NOTE
In most air conditioning applications this minimum
water volume will have a satisfying result.
In critical processes or in rooms with a high heat
load though, extra water volume might be
required.
Installation
height
difference
(*)
(*) Installation height difference: height difference (m) between the highest point of
the water circuit and the unit. If the unit is located at the highest point of the
installation, the installation height is considered 0 m.
Water volume
< 300 l (EWAQ)
< 170 l (EWYQ)
> 300 l (EWAQ)
> 170 l (EWYQ)
<7 m
No pre-pressure adjustment
required.
Actions required:
• pre-pressure must be
decreased, calculate
according to "Calculating
the pre-pressure of the
expansion vessel"
• check if the water volume is
lower than maximum
allowed water volume (use
graph below)
>7 m
Actions required:
• pre-pressure must be
increased, calculate
according to "Calculating
the pre-pressure of the
expansion vessel"
• check if the water volume
is lower than maximum
allowed water volume (use
graph below)
Expansion vessel of the unit
too small for the installation.
