Ecodan Air Source Heat Pump - Mitsubishi Electric ecodan PUHZ-W50VHA2 User Manual

INTRODUCTION

Ecodan Air Source Heat Pump

Must be mounted external to the property in a suitable location with a minimum distance of 300mm from
the nearest wall at the rear of the unit. For minimum distances on any side of the Ecodan refer to page 23.
The unit should never be enclosed.
Cold air is blown from the front of the unit - it should be positioned in a location where this will not cause
a nuisance. The air needs to circulate freely around the unit, the efficiency of the Ecodan will be hampered
if warmer air cannot enter the rear of the unit.
It should be mounted on anti-vibration mounts, these are NOT provided with the equipment.
The anti-vibration flexible hoses should be fitted to the flow /return pipe-work.
Condensate water may be produced which will drain away from the unit. It is suggested that a gravel filled
channel as a soak away, or a similar arrangement to suit the location is installed to overcome this.
An optional drainage kit may be purchased should condensate need to be disposed of in a main drain as
opposed to a soak away type arrangement.
The internal and external flow and return pipework must be insulated and waterproofed externally to
prevent freezing.
All pipework should be insulated, any heat losses here will result in lower coefficient of performance
(COP).
An external temperature sensor is positioned at the rear of the Ecodan. Care should be taken to ensure
this is not placed in direct sunlight.
