INSTALLATION OF YOUR HORIZONTAL APPLICATION C-RECESSED AIR CURTAIN

The C-Recessed air curtain has been designed for recessing within ceiling voids

or bulkheads.

Location

Ensure that the unit is mounted within its height

specification of 1.8m to 2.75m maximum (from floor

level to the underside of the unit/grille) and that it is

situated as close to the door as possible.

Note: The air discharge should be nearest to the

door as shown in adjacent figure. Ensure the air

curtain is as close to the door opening as possible

for best performance, obstructions such as door

opening devices, structural beams etc will reduce

the performance.

Note the C-Recessed air curtain has a series of punched air ventilation slots along one side

panel of the unit which will be within the ceiling void once the unit is installed. There must be

an air gap of 50mm minimum between these ventilation holes and any obstruction/bulkhead

within the ceiling void to allow ventilation air to easily enter the air curtain via these slots.

Furthermore, the ceiling void must be sufficiently large and freely ventilated so there will be

an adequate supply of ventilation air (m3/hr) to the unit, see Table 1. If the ceiling void is

enclosed around the air curtain it will need an air ventilation grille of effective free area (cm2)

as given in Table 1 and an adequate air path within the void for air to enter the punched air

ventilation slots.

C1500R 421 700

C2000R 707 1200

Ceiling Suspension

Make the cut-out in the ceiling to the dimensions given in Figure 1, ensuring the length of the

hole is exact. The air curtain will fit through the ceiling cut-out, ensure there is sufficient

height clearance in the ceiling void to do this. Alternatively, the ceiling can be fitted after the

air curtain has been installed.

Clearance holes for M8 threaded rod to enter from

above are provided on the top face of the casing (4x,

for dimensions see Figure 1) allowing the unit to be

suspended. Insert rod through each hole in top and

attach onto each fixing bracket at lower edge of air

curtain (see insert). Lock rod in place using M8 nut

above and below fixing bracket (threaded rod and

locking nuts are not provided). Ensure rod does not

come below bottom face of unit.

Ensure each of the threaded rods are secured on to

a suitable structure that can support the weight of

the unit (for unit weights see Table 2)*.

* It is the sole responsibility of the installer to ensure that the building fixing points and

suspension system used are suitable for the air curtain being installed

Fitting of the Recessed Grille

The grille consists of a frame, grille core (fitted

within the frame) and four brackets (note: the

brackets are fixed to the frame).

Removal of Grille Core

Prior to fitting the grille to the air curtain and the

ceiling the grille core will need to be removed from

its frame. Release the grille core by unfastening

the two conical bolts fitted at each end of the grille

core. Push against the spring loaded pins and the

grille core can now be pulled clear of its frame.

Note: the grille core will still be attached to the

frame via cord safety ties.

The rectangular hole in the ceiling must be

sized to suit the grille frame, see Figure 1

for dimensions.

Attaching the Grille to the Air Curtain

Before lifting the grille frame into position locate the four M6 bolts (two inside each end

of the air curtain). Remove the M6 bolts and lift the frame into position (ensure that

when fitted the air discharge vanes align with the air discharge of the air curtain, see

Figure 1), screw each M6 bolt through the slot in the grille bracket until all four are

located into place. Adjust the height of the grille frame (via slots in brackets) so the

frame fits nicely against the under side of the ceiling. Once the desired height is

achieved tighten each M6 bolt in place locking the grille frame into the correct position.

Adjusting the Separator Plate

Within the air curtain there is a sliding separator plate,

this needs adjusting up or down to stop the air

discharge re-circulating within the air curtain. To adjust

the separator plate release the M6 bolts at either end,

extend the slide plate so that it will just touch the

topside of the grille along its whole length and tighten

the bolts. It will be necessary to fit the grille core to

gauge where the separator plate should be fitted.

Fitting the Grille Core

Once the above is complete the grille core can be refitted, to do so locate each spring

loaded pin in its locating hole, push against the spring loaded pins to allow the fixed

pins to locate within their fixing holes. Tighten and secure the conical bolts fitted at

each end of the grille core.

Once the ceiling is finished remove the protective plastic film from the recessed grille

frame.

Ambient Models

Ambient units are supplied with a remote switch

unit. The switch unit allows the air curtain to be

powered ON/OFF and select one of three fan

speeds.

Multiple Installation (Ecopower only)

To Master/Slave two or more air curtains together the remote control is plugged into

the Master unit and a RJ lead should be connected from the Master to the Slave

unit(s). Thermoscreens 3m RJ extension leads are available and must be ordered

separately. Additional air curtains, up to a maximum of eight units, may be connected

as indicated below. For Master/Slave configuration an independent mains supply as

per Table 2 must be supplied to each air curtain.

Function

Control

Comments

Standard

Fan Heat Interlock –

The heat output is dependent on the fan

speed. If low or medium fan speed is

selected the heat output can only go up to

first heat stage. Only if the unit is operating

on high fan speed can the second heat

stage be selected. This feature operates in

manual or auto mode.

DIP1 Option

Suitable on vertical electrically heated

Designer air curtain. Maximum heat

output achieved if maximum fan speed

selected. Independently set-up DIP

switch on each mother board.

As supplied, the

default setting would

be for heat and fan

settings to be

independent (DIP1

OFF).

Disable Fan Run-on –

Disable fan run-on. DIP2 Option

(LPHW &

Ambient only)

Must only be used for LPHW and

Ambient air curtains. Independently set-

up DIP switch on each mother board.

As supplied, the

default setting would

enable fan run-on

(DIP2 OFF).

Thermostat Master –

Only the air sensor thermistor in the master

air curtain will be used for measuring the

reference air temperature for the whole

master/slave installation.

DIP3 Option

The air sensor thermistors in all the slave

air curtains will be ignored. This will then

avoid situations on larger doorways with

master/slave air curtains where some

units can blow cold air whilst others can

blow warm air, because they currently all

refer to their own air sensor for control of

the heat output of each air curtain.

The master air curtain need not be the

one that the wall control is plugged into.

As supplied, the

default setting would

be for the air sensor

thermistor on all units

to be measuring

(DIP3 OFF).

Overheat Fan Disable –

If DIP4 is on and thermal overheat trips,

heat and fan circuits are isolated and LED’s

on wall switch flash. If DIP4 is off and TOC

trips out, only the heat circuit is isolated and

the LED’s on the wall switch flash.

DIP4 Option

(Electric only)

Wall switch upgrade required.

The handset has to be powered on.

Independently set-up DIP switch on each

mother board.

To remove fault, isolate electrical supply

to air curtain, reset TOC and reconnect

supply.

As supplied, the

default setting would

enable fan if TOC trips

(DIP4 OFF).

NB: If TOC operates

with an upgraded

switch the LED’s on

switch flash,

regardless of DIP4

settings.

Retain User Settings (toggle) –

If electrical supply to the air curtain is

removed, upon restoring electrical supply

the customer’s settings on the remote

control will be retained, i.e. if unit were

operating beforehand, it would

automatically start up again and operate on

the exact same settings as before.

feature –via

secret key

press (Fan-

down)

Wall switch upgrade required.

To toggle – switch unit on from handset.

Hold Auto button till Auto LED flashes.

Press fan down button to toggle

selection.

As supplied, the

default setting would

be for the unit to start

up again automatically.

Need to do the secret

key presses to revert

back to “nothing

happens” when power

is restored, as we have

it now.

Fan run-on time set two minutes. Built-in If “FAN ONLY” has been selected, at

switch off, no fan run-on.

Reduce time for fan speeds to turn on and

index up through Low, Medium and High

DIP switches fitted on the Ecopower board provide a selection of optional features as described above. Isolate and

switch electrical power off before configuring and/or changing any DIP switch settings.

•Easy plug-in arrangement for remote air sensor thermistor on a 1m lead. Plugging-in the remote air sensor to J3

disables the standard air sensor thermistor already fitted on the Ecopower board. As supplied, the board will not have

the remote air sensor fitted.

•An INHIBIT two screw terminal fitted on the Ecopower board for BMS remote On/Off feature.

If the terminal is linked, i.e. by 2 wires to a remote voltfree contact, the unit will run. If it is open circuit across the

terminal the unit will switch off. This remote On/Off feature has global switching logic, i.e. if you master/slave several

units together you need connect the remote contact to only one of them to turn all units on and off in the master/slave

system. As supplied, a wire link will be fitted to the terminal block on every unit. For summer settings place a 3.3kΩ

resistance across the INHIBIT terminal, with these settings fans only will run even if controller is requesting for heat.

ECOPOWER BOARD

Customer Building Management System

•A HEALTHY two screw terminal is included on the board for a fault signal indication if the electric elements overheat

cut-out has operated. A healthy system provides a 24V DC signal at the terminals compared to an overheat fault which

provides OV DC.
