4.1 Installation advices
Unit placement
The MQH air-to-water heat pumps must be installed in the
open air, in an area where the flow of air to and from the
condenser coil must not be limited. A space restriction, which
reduces the air flow, will decrease the capacity, increase the
power input and, in some cases, prevent the unit from operat-
ing because of an excess of condensation pressure.
The MQH air cooled heat pumps are equipped with propeller
type condenser fan. Therefore, they will not operate with
ductwork on the fan outlet.
In case of installation in an area subject to be hit by strong
wind, direct effect of the wind on the discharge surface of the
fan should be avoided.
The minimum clearances are shown on chapter 8.4 and must
be considered, both to ensure that the unit operates correctly
and to allow easy access.
The units should be installed on a flat and hard, preferably
concrete base.
Care should be taken, at the time of installation, to leave
enough clearances around the unit for maintenance works.
When fixing the unit, a slope of 1 cm/m is recommended to
allow draining of rain water.
For heating mode, if the outdoor temperature is likely to fall
below +1 °C, provide a system to prevent the condensates
from freezing (e.g. heating cord).
For installation in difficult climates, temperatures below 0°C,
snow or humidity, it is recommended to elevate the unit about
20 cm above the floor.
MQH06 and MQH08M/T and MQH10M/T cannot
be installed with advanced inclination to 10°.
The metal grille is used to protect the operators
from injury risks on heat exchanger at the time of
handling and installation. However, risks of
clogging by freeze or hoar frost can be occured on
the units installed in cold or mountainous regions
and exposed to the elements.To prevent all risks,
a shelter is to be provided or simply remove the
protective grille.
