BPS V-CO

Installation Manual

Remove dust and fibres with a soft brush or vacuum cleaner. Use 
caution when blowing dirt out with compressed air to avoid damage to 
the wheel. Keep at a distance!

Oils, solvents etc. can be removed with hot water (max. 70 °C) or 
grease-removing solvents or immersion.

13.7 Legionella Check

Legionella risk management should be undertaken by a competent 
person appointed by the duty holder in accordance with the latest 
edition of the HSE approved code of practice L8 Legionnaires’ disease, 
the control of legionella bacteria in water systems. Particular attention 
should be given to:

Cooling coil.

Thermal Wheel.

Drain trays.

Water reservoirs.

13.8 Electric Heaters

An air handling unit would normally require no heater maintenance. 
However a periodic check is advised to ensure that the fasteners and 
electrical connections are operating correctly.

The electric heater unit is fitted with fail-safe thermal switches (self-
resetting) which will isolate the electric heater supply if a temperature 
of 80°C is detected. This action is performed independently of any 
controls fitted. Nuaire fitted controls will also stop heating if a fan or 
heater failure is detected.

13.9 Bulkhead Lights

Ensure that lights are switched off and isolated before checking or 
changing the lamp.

13.10 General

Inspect all internal and external surfaces to check for corrosion or 
peeling of painted surfaces.

Thoroughly clean affected areas with a wire brush, apply a coat of zinc 
rich primer or similar, and re-touch with suitable finishing paint. Ensure 
tightness of all nuts, bolts, and fixings.

Check all components for general condition.

13.11 Specialist Equipment

Contact Nuaire for maintenance of specialised equipment that 
would have been specified during design stage. A breakdown of the 
component parts can be found on the design specification documents, 
additional maintenance literature is available, please contact Nuaire.

This applies to any components not specifically mentioned in this 
document.

13.12 Maintenance Schedule

13.12.1 Routine Maintenance

Clean all areas of unit and treat any areas of corrosion.

Check all access doors for leakage and if necessary locks should be 
adjusted and any replacement gasket materials should be replaced 
as required. 

Any drain trays should be cleaned and repaired if necessary. 

13.12.2 Every 3 Months 

Check filters and change/clean if required, failure to do so may 
impair the performance and energy efficiency of this unit.

Ensure condensate drains are cleaned clear and that water can 
flow freely from unit.

Check fin coil banks and heat exchangers. If necessary clean with a 
soft brush or vacuum. Check for signs of contamination. 

13.12.3 Annually 

Thoroughly inspect the unit and its components for corrosion, 
acting immediately to treat/restore any damaged areas. 

All electrical terminals within the unit should be tightened. 

Check all earth connections. 

Check control dampers blades. 

Check operation of damper actuators and linkages and adjust as 
necessary. 

Coil faces should be inspected and any dust removed. 

Check any thermal wheel belt, motor, bearings, seals and if 
necessary clean with a soft brush or vacuum cleaner.

14.0 WARRANTY

The 5 year warranty starts from the day of delivery and includes parts 
and labour for the first year. The remaining period covers replacement 
parts only.

This warranty is void if the equipment is modified without 
authorisation, is incorrectly applied, misused, disassembled, or not 
installed, commissioned and maintained in accordance with the details 
contained in this manual and general good practice.

The product warranty applies to the UK mainland and in accordance 
with Clause 14 of our Conditions of Sale. Customers purchasing from 
outside of the UK should contact Nuaire International Sales office for 
further details.

Failure to maintain the unit as recommended will invalidate the 
warranty.

15.0 END-OF-LIFE AND RECYCLING

Where possible Nuaire use components which can be largely recycled 
when the product reaches its end-of-life:

Fans, motors, controls, actuators, cabling and other electrical 
components can be segregated into WEEE recycling streams.

Sheet metal parts, aluminium extrusion, heating/cooling coils and 
other metallic items can be segregated and fully recycled.

EPP, plastic ducting, nylon corner pieces, plastic heat exchangers, 
packaging material and other plastic components can be 
segregated into mixed plastic and widely recycled.

Cardboard packaging, wood, used filters and other paper 
components can be largely recycled or fully processed in energy 
from waste centres.

Remaining Items can be further segregated and processed in 
accordance with the zero waste hierarchy. Please call After Sales 
Support for further information on items not listed above.

IMPORTANT

Ensure that Nuaire product is made safe from any electrical 

/ water / refrigerant supplies before dismantling commences. 

This work should only be undertaken by a qualified person in 

accordance with local authority regulations and guidelines, 

taking into account all site based risks.
