Introduction
The information contained in this document provides details of installation, operation and maintenance for installers and
users. The PREMA ceiling void energy recovery ventilation range comprises a combination of high efficiency centrifugal
fans with EC motors, a counter flow design plate heat exchanger and a casing with acoustic treatment.
General information regarding performance and specifications for the equipment may be obtained from our technical
literature, and / or project specific documentation.
General
All maintenance procedures shall only be carried out whilst the product is isolated from electrical supplies. In order to
minimise the risk of a fan motor unit being started accidentally during maintenance, it is recommended that central control
panels / switchboards are clearly marked with a suitable warning sign.
In addition, before connecting an electrical supply cable to any terminal board, please ensure that the line voltage
matches that stated on the product label. Should product labels become illegible over time it is recommended that these
be replaced.
Delivery
All equipment is inspected prior to despatch and leaves the factory in good condition. Upon receipt of the equipment an
inspection should be made and any damage indicated on the delivery note. No responsibility will be accepted for damage
sustained during the offloading from the vehicle or on the site thereafter. All claims for damage and / or incomplete
delivery must be reported within two days of receipt of the equipment.
The usual method of packing for these products is to be loaded onto pallets and shrink wrapped to minimise water
ingress.
Safety Standards and “CE” Marking
In-line with our policy of continuous product improvement, we are constantly striving to deliver more efficient products that
comply with current safety standards. The standards and guidance contained within this documentation therefore reflect
compliance with these safety standards and regulations. In addition to the advice given within this document, we strongly
recommend that all personnel who may be exposed to risks during the installation, use or maintenance of our equipment,
should ensure that they comply with all relevant safety regulations that are in force within their respective countries.
Elta Group Building Services does not accept responsibility for personal injury or damage caused to property resulting
from non-compliance with these safety standards, or as a result of any none approved product modifications.
Warning / Danger Labels
All internal cabling is situated within the bypass channel, behind the isolator panel. No drilling into this unit is permissible,
as any such action may result in an electric shock and will void the external L2 leakage rating (this applies to all of the
panels and controls area).
The units can have a number of different warning labels or symbols affixed to it, which should not be removed.
Product risks have been analysed in accordance with Machinery Directive 2006/42/CE. The associated directive handbook
contains information and advice for all responsible personnel and is designed to minimise possible risks of personal injury
or damage to property.
