The ecovent®

mini series is a range of Heat Recovery units, with dues up to 0.1 m³/s.

Suitable for either plantroom, ceiling void or internal locaons. As standard, each unit will have been

supplied pre-wired to an isolator or ﬁtted control panel, as speciﬁed at the me of order.

The standard operang temperature of these units is -20 to +40 °C.

For further technical details regarding dimensions and weights, contact VES on 02380 461150,

Immediately upon receipt of goods, check for possible damage in transit paying parcular

aenon to fan impellers, drain connecons and unit casing. Prior to installaon please check

to ensure alignment and smooth rotaon of the impeller aer 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 essenal

to inform VES Andover Ltd. within 7 days of delivery quong sales order number and the unit

type, as found on the unit nameplate. Aer this period, VES would be unable to accept any

claim for damaged or missing goods.

The enre 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

recommendaons, with due regard to the current HEALTH AND SAFETY AT WORK ACT and c

to all relevant statutory regulaons.

Where a unit is installed so that a failure of components could result in injury to personnel,

precauons 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 whilst

operaonal, a guard should be ﬁtted or steps taken to prevent this. 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 accordance with Health and Safety and Building

Regulaons. For conﬁrmaon of required access please see the appropriate unit outline

drawing.

Consideraon must also be given by the installer for adequate illuminaon of the unit locaon

in order for safe maintenance. Further consideraon should be given to the unit’s posion and

secured into place as appropriate.

Mounng hangers, door furniture, isolators etc. extend beyond the casework and so are

vunerable to accidental damage. Take necessary precauons so as not to cause damage whilst

handling the unit.

The weight of each unit/secon is speciﬁed on the outline drawing and the total unit weight

will be displayed on the unit inspecon label. When liing the unit using a fork li truck

ensure the whole unit is supported by the full length of the forks. It may be necessary to use

fork extensions to fully support the unit properly. The centre of gravity may be offset from the

centre of the unit; this needs to be taken into consideraon when liing the unit.

Handle with care. Failure to fully support the unit during liing may result in damage to the unit.

Units are to be rigged and lied using spreaders, taking

into account the weight of the unit, and liing gear should

be arranged so as not to bear on the casework see right.

For installaons using a metal framing systems (such as unistrut etc.) the feet can be rotated 180°

to allow for beer ceiling clearance. Carefully remove/retain the ﬁxings and reposion the feet as

required. Ensure all ﬁxings are correctly reinstated and ghten to 8Nm.

When hanging units from drop-rods, ensure that the load is evenly spread and that ALL feet are

used within the support, including those for ﬁtted silencers if included.

Ensure that the drop rod used is selected appropriatedly to accomodate the load of the unit.

When accessing the unit ensure the access panels are handled/opened in a controlled manner

so as to avoid damage to the unit or injury to personnel. This is parcularly important with

boom access units. Ensure the AHU has been given me to come to a complete stop before

aempng any work to the unit

The unit is ﬁed with a drain pan terminated to a Ø15mm internal drain spigot and a Hep20 push

ﬁt straight connector. Join through the case using the hole provided into the connector, trap as

required and terminate via an appropriate waste system or by use of a peristalc pump.

It is important that the drain be allowed to clear without obstrucon. Ensure that the unit is

mounted level and the drainpan is angled so that water drains towards the drain spigot as the

drain may have moved during transit/installaon.

Failure to do this may result in excess condensaon within the unit and possible ﬂooding.

The electrical supply MUST BE FULLY ISOLATED before aempng to aﬀect any work on this unit.

All electrical connecons to any unit must be carried out in accordance with the current

edion of the I.E.T. Regulaons, only competent Electricians should be allowed to aﬀect any

electrical work to our units.

It is recommended that the cable entry point should be at the side of the unit as shown below in

ﬁgure 8. It is the responsibility of the installer to ensure that a suitable cable gland (giving

adequate protecon and strain relief) is ﬁed, and in doing so also ensure that no internal

components are damaged during this installaon.

Do not connect any unit to an electrical supply voltage outside of the speciﬁcaon.

Take parcular care to note the posion of the drain and associated pipework. Make certain any

swarf produced is removed before use.

It is the installer’s responsibility to supply earth protecon through the building installaon device

and a dedicated, isolated power 220-240VAC 50Hz supply with overload protecon, to account for

motor start up currents. See below for speciﬁc fan details Fig.

The installer must provide a switched fused spur. The spur must be a 5 Amp, double pole connecon

point that is local to the unit (the contact separaon of the fused spur switch should be at least

3mm).

Although the controls will interface with a building management system (BMS), inial setup can only

be completed using a handheld human-machine interface (HMI) which will have been supplied with

the order. There are two versions of HMI available, a roller buon version and a six-buon version.

The buon operaon is described below but the menu operaon is the same for both.

There are two modes of operaons available. Read only mode, whereby several parameters may be

viewed for a quick visual inspecon of the systems current state and Commissioning mode, which

allows the user to view and edit all parameters. This includes funcons such as adjusng fan speeds,

temperature setpoints, heang type and integrated communicaons sengs. Commissioning mode

is typically indicated by the presence of 3 keys in the top right-hand corner, in read only mode this

will be blank.
