1 Introduction

The Ecovent Plus series is a range of heat recovery units,

direct and belt driven, with duties up to 2m³/s. Suitable for

plant-room, ceiling void and external locations, each unit will

have been supplied with either no pre-wiring, pre-wired to an

external isolator or with fitted control panel as specified at

the time of order. The standard operating temperature of

these units is –20 to +35°C.

For further technical details regarding dimensions and

weights, contact VES on 08702 404340, quoting the sales

order (SO) number and the unit type as found on the unit

nameplate

or visit www.ves.co.uk.

2 Receipt of Goods/Handling

Immediately upon receipt of goods, check for possible

damage in transit paying particular attention to fan impellers,

motor, flexible connections, coil connections and unit casing.

Prior to installation please check to ensure smooth rotation

of the impeller after transit. Also check to ensure that any

ancillary items are included. These will normally be supplied

fitted or, in the case of small items, taped to the unit.

In the event of any damage having occurred or if any item is

found to be missing, it is essential to inform VES Andover

Ltd. within 7 working days of delivery quoting sales order

number and the unit type, as found on the unit nameplate.

After this period, we would be unable to accept any claim for

damaged or missing goods.

IMPORTANT

Handles, lids, housings and coil connections must not be

used as lifting points

When moving the unit, handle with care and in such a

manner as to avoid damaging the external finish as this may

reduce the ability to resist corrosion. Units are to be rigged

and lifted using spreaders, taking into account the weight of

the unit, and lifting gear should be arranged so as not to

bear on the casework.

For further details, refer to the unit outline drawing.

3 Installation

The entire system must be considered for safety purposes

and it is the responsibility of the installer to ensure that all of

the equipment is installed in compliance with the

manufacturer’s recommendations, with due regard to the

current HEALTH AND SAFETY AT WORK ACT and conforms

to all relevant statutory regulations.

Where a unit is installed so that a failure of components

could result in injury to personnel, precautions should be

taken to prevent such an injury. If the unit is installed where

there is a reasonable possibility of persons or objects

coming into contact with the impeller, a guard should be

fitted.

It is the installer’s responsibility to ensure that access panels

are not obstructed in any way and safe working access for

maintenance must be provided in line with Health and Safety

and Building Regulations.

For optimum unit performance, careful consideration must be

paid to the location of the unit in relation to the ductwork and

associated items; placing the unit directly adjacent to a bend

in ductwork will impede airflow and reduce performance.

Consideration must also be given by the installer for

adequate illumination of the unit location in order for safe

maintenance.

Sectional (tubular framed) units should be assembled using

self-adhesive rubber tape at the joints prior to assembly so

as to prevent air leakage; replace with similar if damaged.

IMPORTANT

Only experienced fitters should undertake this work. Take

necessary safety precautions when working in elevated positions

Electric Heater Batteries

Supply to the heater should be 1ph or 3ph with separate

neutrals; confirmation of this can be found on the unit

nameplate. Cables should be of silicone rubber, fibreglass or

of a similar high temperature insulated type and be installed

to current I.E.E. Regulations, ensuring a sufficient earth

connection to the terminal provided. Care should be taken

not to overstrain the terminal pillars as this may permanently

damage the elements.

The heater is fitted with a manual reset high temperature cut-

out with normally closed (NC) terminals. The cut-out is set to

break if the duct temperature rises above 130°C and must be

connected in series with the main contactor coil circuit if the

heater is to be isolated in the event of overheating.

The electrical supply must be isolated before attempting to

reset the manual cut-out.
