4.0 INSTALLATION
The Cooling Module (MR-ECO-COOL-V) has been designed for use
with the MRXBOXAB-ECO5-AE(OH)CV and 7713807 control only.
Isolate power supply before commencing work. Ensure the Nuaire
controls are electrically isolated from the mains supply.
Recommend mounting method uses the EC05-AE-1Z-STND.
Alternatively angled brackets are available (Part Number:
7713882). However, it is the responsibility of the installer to ensure
the mounting surface for the brackets will adequately support the
combined weight of both MVHR and Cooling module (Combined
Weight = 121Kg).
4.1 General Installation
Installation must be carried out by competent personnel in accordance
with the appropriate authority and conforming to all statutory
governing regulations. All mains wiring must be in accordance with the
current I.E.E. Regulations, or the appropriate standards. Ensure that the
mains supply (Voltage, Frequency and Phase) complies with the rating
label.
ADF 2010 DVCG: "Ensure the final location of equipment offers
sufficient space to allow access for maintenance. The fan unit [including
cooling module] should be installed to allow sufficient space for end
of life replacement of the whole unit or key mechanical/electrical
components. This should be achievable without the need to remove
fixed structures or significant lengths of connected ductwork.” In
addition to the space requirement the total weight of the fan unit and
cooling module products should be considered to allow the use of
mechanical lifting equipment required to safely remove and replace the
product.
The unit and its controls must be installed indoors, and away from
direct sources of frost,
heat and water spray or moisture generation.
Ambient temperature range -5 to 40°C.
This unit must be earthed.
When installing the unit, take care not to damage electrical or other
hidden components –
do not drill the unit casing
.
This units contains pressurised components.
The cooling unit is an electro-mechanical device that contains and uses
R134A refrigerant.
This unit contains live electrical components, moving parts and
refrigerant under pressure. Always site out of reach of children and
protect from vandalism and accidental damage.
Keep the unit horizontal during installation and level the unit in its final
position. Once in final position, leave unit for a minimum of 4 hours
before activation.
