5 HYDRAULIC INSTALLATION
22
SUPPORTS AND LEVELLING
The appliance must be correctly levelled by placing a spirit level on the upper part.
If necessary, level the appliance with metal shimming; do not use wooden spacers as these deteriorate quickly.
CLEARANCES AND WARNINGS
Position the appliance so as to maintain minimum clearances from combustible surfaces, walls or other appliances, as illustrated in
Figure 5.2 p. 22.
Minimum clearances are required for maintenance accessibility.
The fumes outlet terminals must be installed in such a way that they do not allow the fumes to collect or return to the circuit in the
unit's installation area. The outlet terminal must be constructed in conformity with established regulations.
Do not install any cover or obstruction to the evacuation of the air issuing from the fan.
When deciding on the installation position, especially if multiple units are used, consider that each unit requires 11,000 m 3 /h of air
for the coil. Make sure that the installation and position allow for sufficient air flow to the coil and prevent recirculation, which would
reduce efficiency and shut-down the appliance of the units and force them to switch off.
Figure 5�2 – Clearances
Place the appliance preferably far from environments where silence is required, such as bedrooms, meeting rooms, etc.
Evaluate the noise impact of the appliance with respect to the installation site: avoid placing the appliance in locations (such as cor-
ners of buildings) where noise could be amplified (reverberation effect).
5�3 HYDRAULIC CONNECTIONS
General indications
▶
The hydraulic installation may be realized using pipes in stainless steel, black steel, copper or crosslinked polyethylene for heat-
ing/cooling applications. All water pipes and pipe connections must be properly insulated in compliance with current regula-
tions to prevent heat losses and outer condensation.
▶
To prevent icing in the primary circuit during winter time, the appliance is provided with antifreeze functions activating the water
circulation pump of the primary circuit (if controlled by the appliance) and the burner of the appliance itself (when necessary). It
is therefore necessary to ensure a permanent supply of electricity and gas to the appliance throughout the whole winter period.
If it is not possible to ensure a permanent supply of electricity and gas to the appliance, use glycol antifreeze of the inhibited
monoethylene type.
▶
If glycol antifreeze is to be used (see Paragraph 5.6 p. 25), DO NOT USE galvanised pipes, as they are potentially subject to cor-
rosion phenomena in the presence of glycol.
▶
If using rigid pipes, use vibration damping couplings at the water and gas connections on the appliance's service plate to prevent
vibration.
