1.7. Conformity


CE, under formal condition that the final product integration is made in conformity with the applicable
standards.

Eco design (Directive 2009/125 / EC) - LOT 6 (1253/2014). See details on our website: www.lemmens.com.

2. INSTALLATION INSTRUCTIONS

2.1. Installing the unit


Make sure the unit is installed on a flat surface

Make sure to allow accessibility to all the cabinet's components (controller, fans, heat exchanger, filters) to
allow easy maintenance, and possible replacement of defective elements. We recommend a minimum
clearance distance of 50 cm on the access side of the HRmural 450/600/800, and of 90 cm on the access side
of the HRmural 1200 models. A clearance of 50 cm is recommended for all the 3 other sides.

Special care has been taken to deliver an airtight unit. Make sure the ductwork is also very airtight, especially
at the connections with the unit on the supply air side.

If the unit is installed outdoors, take the dominating winds into account when orientating the unit. Try to protect
the air inlet as much as possible from storm winds and rain.

2.2. Connecting the drain pan


To insure a good flow of the condensates the unit should be slightly inclined ( 2°) in the direction of the water
flow. This also avoids water stagnation in the drain pan.

The siphon must be properly installed to allow good water flow:
a) If the HRmural unit is installed indoors:
Before starting, control the following points:
- if the drain pan is watertight;
- the connection between the drain pan and the evacuation pipe is
airtight;
- the height of the siphon is at least of 120 mm;
- the pressure difference between outside and inside the unit cannot
exceed 350 Pa;
- check for the presence of a ventilation downstream of the siphon;
- the siphon is accessible to allow cleaning
b) If the HRmural is installed outdoors:
The siphon delivered with the HRmural for outdoor application is
a special siphon with a membrane. It is thus not necessary to fit it to
a drainage pipe as the water can directly drop on the ground.
The membrane integrated into this type of siphon creates the air
tightness.
