3.5 Thermal Wheel Transport Packing
Thermal wheel modules can be delivered with transport packing blocks,
ensure any transport blocks are removed prior to operation of the
thermal wheel.
The thermal wheel belt is unhooked to prevent the thermal wheel belt
from stretching during transportation.
The thermal wheel motor is attached via a hanging motor bracket. To
install the belt lift the spring motor upwards, hook the belt onto the
pulley and slowly release the motor.
Ensure that the rotation sensor is aligned with the sensing studs,
as this can become misaligned during transport/installation thus
causing a fault signal.
3.6 Connections
3.6.1 Ductwork
Nuaire do not provide ductwork connections with units, instead
the open ended framework should be utilised. Spigots are available
as an option; refer to technical documents for information relating
specifically to the manufactured unit.
3.6.2 Coils
When connecting coils, special care is needed to allow for expansion
and contractions. Prior to any equalising connection, ensure that the
thermostatic expansion valve for the DX coil is securely fitted.
Each coil section should be trapped and special care should be taken to
ensure that there are no vertical rising condense lines, unless pumped.
If a frost coil is not fitted then appropriate control methods must
be taken to prevent the coils, filters and other equipment from
freezing (by others).
3.6.3 Pipework
Care should be taken to ensure that all pipework is adequately
supported, therefore ensuring that no additional weight is added to the
unit. Extra precaution should be taken to prevent pipe damage on site,
as the fragile pipework will protrude from the side of the unit.
3.6.4 Condensate Drains
Modules that incorporate heat recovery, cooling coils or humidifiers
may produce condensation during use. An insulated drip tray and drain
connection is provided, and should be connected to a suitable drainage
point.
Where plate heat exchangers are in use, condensate drainage points are
provided. It is the installers’ responsibility to ensure connection to the
appropriate trap and drainage. Due to the bespoke nature of these units
condensate connection locations can vary during the design process
and should be confirmed on an individual basis.
Horizontal plate heat exchangers have 2x 22mm drain connections.
Connections are typically located on the underside of the PHX module
at the extract inlet and extract outlet (Figure 5).
Vertical plate heat exchangers have 2x 22mm drain connections.
Connections are typically located at the bottom of the access side of
the PHX module (Figure 6).
Provision may be required, and if so, should be made, for the fitting of a
correctly sized cleanable trap to each drain connection.
