Installation; Siting The Installation - Panasonic 140 Installation And Maintenance Manual

9. Installation

The unit is not designed to withstand weights or stresses from adjacent equipment, pipe work or
constructions. Any foreign weight or stress on the unit structure could lead to a malfunction or a
CAUTION
degradation with dangerous consequences for personnel and property. In such an event, the warranty shall
be null and void.
The unit base shall be arranged as indicated in the manual. There could be a risk of personal injury or
CAUTION
damage to property in the event of the unit being incorrectly supported.

9.1. Siting the installation

The ECOi-W must be installed outdoors with suffi cient surrounding clearance to enable unobstructed air circulation through
the appliance and access for maintenance work.
Do not expose the ECOi-W to emissions from chimneys or vents. Fumes charged with soot or grease as
CAUTION
well as acidity are likely to clog or damage the condenser irrevocably. This would void the warranty.
Prevailing wind
In the case of the unit being sited in areas exposed to high winds, you must avoid the wind hitting the fan blowing surface
areas directly to avoid any risk of recycling cooled air. Exchanger fan operation can be disrupted by strong winds, which can
cause de-icing problems and fan malfunctions.
Unit operation depends on air temperature. Any recycling of air extracted by the fan lowers the air intake
CAUTION
temperature across the exchanger fi ns and alters the standard operating conditions.
9.1.1. Condensate water management in heating mode
Depending on temperature and outdoor air humidity conditions, water vapour contained in the air can condense on the fi nned
heat exchanger and even form ice under low outdoor temperature conditions (around < 5°C). This condensate water and
defrosted water runs off via outlets provided under the exchanger. To aid water run-off and avoid frozen water remaining in the
appliance in winter, we recommend that it is mounted at a height ≥100mm above the ground or supporting structure. In this
way, water can run off freely and be absorbed into the ground, or channelled to a basin built under the appliance, in order to
protect the environment.
In areas where outdoor temperatures fall below 1°C, the system can be equipped with a condensate anti-freeze protection
system (e.g. a heated pipe sheath, optional accessory not supplied with the standard unit).
9.1.2. How to reduce noise pollution
In order to contain noise levels, we equip our appliances with quiet fans and encase the technical compartment in sound-
proofed panels. However, noise levels can be reduced even further by following a few installation precautions:
• Do not install the appliance near a window.
• Do not install the unit in enclosed or confi ned yards, narrow locations where noise may be refl ected on walls.
• Install rubber pads or anti-vibration pads (available as an option) under the appliance.
• Do not join the concrete slab supporting the appliance to the structure of the dwelling (structure- borne noise transmission).
• Electrical and hydraulic connections to the unit must be fl exible to avoid transmitting vibrations.
