Warning
To ensure safety and compliance, please refer to O&M manual for wiring, fan run-on, and
installaon instrucons.
Warning
6.1 Airflow
Cauon The heater can be used for horizontal or vercal airflow. The air should be evenly
distributed across the duct and the minimum air volume as stated on the air heater name
plate must be maintained.
6.2 Thermal
Cutout (Auto)
(EHB opon only)
Every heater is provided with a thermal cutout which will break contacts when the duct
temperature rises above 70 °C. This cutout is provided to comply with M & E specificaons
and will require removal of the terminal cover to reset.
Supply must be isolated before removing cover.
Warning
N.B. It is very important that all electrical connecons are properly made. Elements are
tested prior to dispatch and are within tolerance of ±7½ W of total load. If the elements are
found to be faulty they can be easily removed and replaced. Elements stored in damp
condions may need drying to aain correct insulaon readings - contact VES Andover Ltd. if
in doubt.
6.3 Tesng
(EHB opon only)
Connued
•Supply to Heatline should be 1ph or 3ph and a neutral - refer to name plate for
correct supply.
•The heater is fied with a manual reset high temperature cutout which has NC
(normally closed) terminals and an air flow pressure switch. This is connected in
series with the main contactor coil circuit, to remove power from the heater in the
event of over-temperature or airflow failure. Under no circumstances is this circuit to
be by passed.
•Ensure sufficient earth connecon to terminal is provided.
•The speed controller must not switch off fan independent of control system or
allow airflo w to fall below stated volume on the electric he ater baery.
•Fan run on mer r equired. Turn off 0-10 V heat demand signal 2 minut es before fan
enable signal.
•Separate cables should be ins talled for 0-10 VDC, Control signal and 24 VAC switched
enable signal in c ompliance BS7671/2018.

heatline Duct mounted Heaters
Coil Installaon 7 Coils should be piped according to any relevant local codes of pracce. Where threaded
connecons are supplied, the only approved method of joinng is by use of Boss white and
hemp. The thread fied to the coil is to be supported at all mes whilst making joints. All
external piping is to be supported independently from the coil. Fluid filters are
recommended.
It is important that water and steam coils are protected against damage from extreme
weather condions during the winter season. If the water is allowed to freeze in the coil
system, damage may occur potenally bursng pipes and resulng in emergency problems.
Fing a frost thermostat at the unit inlet and ensuring that boilers run connuously in low
ambient temperatures can help to prevent this.
Heang c oils do not c ool immediately when the hot w ater supply is turne d off. The residual
heat must be dissipated to avoid damage. The connuous running of the fan aer
shutdown resolves this, by operaon of a run-on mer; the recommended length of run-on
is 2 minutes minimum.
On HeatLine units, a Low Pressure Hot Water (LPHW) coil will be installed. Coils are normally
suitable for LPHW at 82 °C flow and 71 °C return temperature. LPHW coils are supplied as
standard with an air vent and drain plug located on the pipe work immediately adjacent to
the coil connecon. The air vent should be at the highest point, with the drain at the
lowest. The coil should be regularly vented so as to avoid potenal air locks, resulng in a
fall off of duty.
It is recommended that a check be made as to whether any treatment is required to the
water supply for prevenon of corrosion and scaling of the equipment. Informaon
regarding the necessary acon to be taken can be obtained from the relevant Local Water
Supply Authority.
The unit will have been supplied with connecons either le or right-hand side looking in
direcon of airflo w. Please see order acknowledgment for confirmaon of this handing.
Should you need to alter this please consult VES Andover Ltd as unit adjustment may
invalidate your warranty.
LPHW units feature a coil connecon c over. To access during ins tallaon c arefully remove
the cover by unfastening the fixings ar ound the cover. Holes have been provided in the
housing base for pipe w ork entry. Please follow the appropriate manufacturer’s instrucon
carefully when fit ng a v alve actuator. Ensure that the cover and fixings ar e replaced upon
compleon.

When the electrical heater is switched off, the fan overruns for at least 3 minutes (param-
eter P54 factory set by VES) to avoid over temperature of the electrical heater or prevent the
thermal cutout from responding. In case of fan failure, the thermostat cannot protect the
electrical heater against over temperature. That is why the electrical heater features a
separate safety device (thermal cutout).
Note: For the BMS opon the fan run on must be controlled by others
