Immediately upon receipt of goods, check for possible damage in transit paying parcular aenon to fan
impellers and casework. 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 fied or, in the case of small items, taped to the unit.

The roundfan
roundfan
is designed for horizontal or vercal mounng. Airflo w in the s ystem must be
in the direcon as shown on the fan casing. When installing in a vercal configuraon it is the
installer’s responsibility to fit an appr opriate weather c owl to prevent water ingress. It is also
recommended that a suitable drain should be incorporated into the adjoining ductwork to
reduce the likelihood of water contaminaon in the event of rainwater entering the ductwork.
The is designed to fit dir ectly inline of a tube s ystem. It is recommended that the
unit be held in posion with padded fast clamps to reduce noise breakout and vibraon.
Alternave (permanent) fixings can be used but are likely to cause noise breakout and
vibraon, inspecon and cleaning of the unit will be harder to implement. Addional support
is available parcularly for the larger units, by means of oponal mounng feet.
Where provided spigots should not be used to support the ductwork and used solely as a
means of ductwork connecon.
These fans are not suitable for use in explosive or fire-hazardous environments
All of the components are fied inline with the fan and ductwork. For externally mounted
units, it is essenal that the casing is posioned so as to orientate the terminal box on the
underside of the unit. This will ensure that surface water runs away from the terminal box and
off the unit. To ensure that waterproofing is achie ved by the unit si licone should be run ar ound
the join in the casing and terminal box.
In situaons of e specially high humidity, provide a s traight air duct secon a t least 1 me tre
long on the intake spigot side for fans mounted in the horizontal posion.

Warning
Warning
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.E Regulaons, only competent Electricians should be allowed to affect any electrical work to our units.
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.
It is the cus tomer’s responsibility to supply e arth fault protecon thr ough the bui lding
installaon device and a dedicated, isolated power supply with overload protecon.

Warning
Maintainance 6
Before aempng to carry out any work on our units, all accompanying documentaon including warning
labels on the unit must be referenced.
Should it be necessary to remove any component ensure that these are secured into posion once
reinstalled. It is crical that aer any maintenance work has been conducted that all components
removed/replaced be refitted correctly by a competent engineer.
Before aempng to carry out any maintenance work, invesgave or repair work on our units,
the unit MUST BE COMPLETELY ISOLATED from its electrical supply. Ensure a minimum of tw o
minutes aer electrical disconnecon before removing access panels. This will allow any
moving parts to come to a rest. Care should also be taken when accessing external units as the
wind and elemen ts may cause moving parts to ‘windmill’.
In general, this series of units require little maintenance. In the unlikely event of component failure, spares
are available from stock at VES Andover Ltd.
Check inside the unit for accumulaon of dust, grease etc. If the fan impellor is heavily soiled,
clean out carefully by hand (ensure the unit is properly isolated). Failure to do this periodically
could lead to a loss of performance or the fan to become out of balance, leading ulmately to
bearing failure.

Maintainance 6
roundfans used in a supply system usually have a fi lter box, with a dis posable fi lter. Every few
months inspect the fi lters, if the fi lter is he avily soiled replace accordingly. To inspect or
replace a fi lter, simply r emove the fi lter box lid t o gain access to the fi lter.
Depending on the unit configuraon: Inspect and clean if necessary electric heaters, silencers,
screen guards and wall shuers. By doing so regularly performance will be maintained.
To gain access to the f an for inspecon, main tenance and r epairs: remove padded fast clamp
(or permanent fixings) from one end of the unit and carefully move the ductwork to one side
and carry out maintenance. If on inspecon of the unit more access is required, disconnect the
unit and remove the other padded fast clamp (or permanent fixings) this will allow careful
removal of the fan to carry out maintenance work.
