4.2 Positioning of heat pump
When positioning the appliance the following aspects should be taken
into account:
• Place the heat pump indoors on a flat, firm surface that can withstand
a weight of at least 500 kg.
• The ambient temperature around the heat pump shall be between
+10 °C and +30 °C.
• When positioning the heat pump, the heat pump's sound pressure
level must be taken into account; suitable location is next to an
exterior wall or insulated interior wall
• A drain/floor drain must be located in the room in which the heat
pump is located.
• There should be space for pipe routing for heating circuit and DHW
connections; air duct routing; and drain.
• Consider the accessories that will be installed (see chapter 12.13)
5 Installation
CAUTION
Risk of injury!
According to EN 60335-1, section 20.1: the heat pump must be
anchored to keep it from tilting.
At least one of the cold water inlet or the domestic hot water outlet
pipes has to be done with a rigid pipe that is fitted to the wall.
CAUTION
Risk of injury!
During transport and installation there are a risk of crushing injury.
During maintenance internal parts of the appliance can become hot.
The installer are obliged to wear gloves during transport, installation
and maintenace.
NOTICE
Risk for operational disruptions caused by contaminants in pipe!
Particles, metal/plastic filings, flax and thread tape residue and similar
material can get stuck in pumps, valves and heat exchangers.
Avoid particles in the pipe-work.
Do not allow the pipe components and connections to be stored
immediately on the ground.
Ensure that no filings remain in the pipes following deburring.
Flush the pipework to remove foreign objects.
5.1 Transport
The heat pump must always be transported and stored upright. The heat
pump is allowed to lean slightly, temporarily, but it cannot be laid flat.
When transporting without the accompanying transport pallets, the
front cover must be removed to avoid damage.
The heat pump may not be stored in temperatures below zero.
To facilitate the heat pump’s transportation, the refrigerant module can
be separated from the hydraulic module.
Refrigerant box removal
The weight of the refrigerant box is 55.5 kgs, therefore it is
recommended that two service technicians perform the lifting
procedure.
