Installation Manual
Airflows of less than 50 l/s may cause the in-built thermal overload
protection to activate to protect the unit. Ensure airflows are
balanced and commissioned in accordance with the original design
criteria.
The Cooling module MUST not be run without the specified
minimum airflow. This can result in the compressor overheating
and may invalidate the warranty.
Typical installation is Floor Mounted using (ECO5-AE-1Z-STND).

Following the MRXBOXAB-ECO5-AE(OH)CV being levelled and
installed on ECO5-AE-1Z-STND.
The supplied gaskets must be installed as shown in Figure 6. Remove
the backing paper of the foam gaskets adhesive side down and align
with the holes of the MVHR unit.
Lift the cooling module (Section) above the MVHR unit and lower
into place. Do not drag the unit over the foam gaskets as this may
damage foam gaskets.
Once in position secure the side brackets with the fixings supplied
(fitted to the units) and secure the top of the unit to a suitable surface
with the adjustable top bracket supplied (Figure 6).

4.2.1 Opposite Handed Units
The Cooling Module can be installed on opposite handed MVHR units
by rotating the module 180°. In doing this the drain, fly lead and access
to coils will be flipped to the opposite side. The drain position will be
located towards the front at the bottom of the unit.

4.3 Condensate Drain Installation
The unit provides an external 15mm Ø condensate drain pipe fitted
flush to the outer case to minimise its foot print. Conventional push on
plumbing connections, connect to the drain (MAX Outer Diameter of
fitting: 37mm).
Ensure the cooling module is installed level.
If the condensate pipe is fitted in an unheated space the pipe should be
in insulated to prevent freezing. Ensure the cooling module has its own
dry trap separate to the MVHR.
4.3.1 Standard Hand Installation
The drain is positioned at the rear bottom corner on the right-hand side
panel on a standard hand unit.
4.3.2 Opposite Hand Installation
The unit is rotated 180°, positioning of the drain towards the front, at
the bottom corner on the left-hand side panel.

5.0 DUCTING
Before commencing ducting installation reference should be made
to building regulations document "Domestic ventilation compliance
guide". This document supports ADF2010 and details installation,
testing and commissioning of all ventilation systems.
It is recommended that rigid ducting must be used it all times. Fresh-air
Intake and stale air Exhaust ducts will carry cold air in winter. Supply
air duct will carry cold air when Cooling Module is operating. Therefore
Intake, Exhaust and supply ducts will be at risk of condensation forming
on external surfaces and should all be thermally insulated.
Any duct component including ancillaries such as carbon filters must
be insulated if they are carrying colder air produced by the cooling
module. Flexible connections should be avoided. Nuaire Ductmaster
thermal ducting should be used on Intake, Exhaust and Supply duct
runs. If flexible connections cannot be avoided, FLDI150 Insulated
Flexible Duct should be used.
Ducting must be installed in such a way that resistance to airflow is
minimised. Bends should be kept to a minimum.
Ducting joints must be sealed with suitable duct sealant and needs to
be taped. Ducting shall be adequately and reliably fixed.
Ducting to cooling module must be securely fixed with screws to the
spigots to prevent access to live parts.
