IMPORTANT SAFETY ADVICE

DO NOT COVER OR OBSTRUCT the air inlet or outlet grille.
ENSURE THE APPLIANCE IS EARTHED.
Do not use this heater in areas where excessive dust exists.
Do not use this heater with young children unattended.
This appliance is not intended for use by children or other

persons without assistance or supervision if their physical,

wiring regulations.

Architectural Air Curtains

Models : ARC10E, ARC15E, ARC20E, ARC10W, ARC15W , ARC20W, ARC10A, ARC15A & ARC20A

Fixing Positions

This appliance may be either fixed to a ceiling - see Fig. 1 or floor
mounted see Fig. 2 using an appropriate foot.
A minimum distance of 500mm is required from top of the
appliance to the ceiling (see Fig. 1) and also the distance between
the bottom of the appliance and the top of the door should be
kept to a minimum (see ‘C’ in Fig. 1).
To open the appliance, remove the inlet grilles (‘x’ in Fig. 3)
Remove the front panel (‘z’ in Fig. 3).

Horizontal Mounting

By using the fixing holes in the top of the air curtain, attachment
to a ceiling over the product can be achieved using suitable M10
threaded steel rod or similar supports of sufficient strength ­see ‘s’ in Fig. 1.

Vertical Mounting

The architectural range of air curtains can be vertically mounted
using a suitable floor foot (Ref: ARCVMF). Contact Dimplex or
your service agent for further information. Refer to Fig. 2 for fixing
details.

Electrical connection

All products are fitted with a microprocessor control. Electrical
power and control connections are made as shown in Fig. 6 & 7.
A suitable local isolating switch must be provided in the electrical
supply circuit with at least 3mm clearance on each pole. In
order to access the electrical connections, remove the inlet grilles
(see ‘x’ in Fig. 3). Remove the front panel (see ‘z’ in Fig. 3) and
also remove the mains cover plate (see ‘y’ in Fig. 3).

ARC Electric Models

Feed an appropriate supply cable as shown in Fig. 4 and attach
to the terminal block (see ‘a’ in Fig. 4).
Note: Ensure that cables are secured to the cable tray with fixing
ties to avoid contact with the elements.

ARC Water/Ambient Models

Feed an appropriate supply cable as shown in Fig. 5 and attach
to the terminal block (see ‘a’ in Fig. 5).
A suitable cable for a switch panel (kit ref. - CABC1 for electrically
heated models or CABC2 for water heated/ambient models)
can be similarly introduced through the top panel and connected
to the circuit board.
If the unit is to be operated in conjunction with a door switch, a
normally closed switch should be wired (see ‘D’ in Fig. 6 & 7) as
appropriate - see also ‘Switch Panel Instructions’.
If the unit is to be connected to a Building Energy Management
System, connections to be made (see ‘G’ in Fig. 6 & 7) as
appropriate.
Ensure that the air curtain is securely fastened in position and
that the supply cables are firmly clamped before operating the
appliance.

Water connection

Models designed for use in conjunction with a low pressure hot
water supply should be individually connected (in a parallel
circuit) to the flow and return pipe-work.
Connections (see ‘a’ in Fig. 8) are ¾” BSPT and isolation valves
(see ‘b’ in Fig. 8) should be fitted as close to the air curtain
connection points as possible. Care should be taken to release
as much air as possible to prevent air locks.
Maximum water supply conditions are 100ºC and 10 bar
(1.03MPa).

Electrically heated variants

Operation using switch box - CABC1

Switch on electrical supply to the air curtain. Switching the switch
marked ‘I’ energises the fan. The fan switch allows either low or
high fan speeds to be selected. The heat selection switch allows
heat setting to be chosen.

 - Off
 - ½ heat
 - Full heat

The A / M (auto / manual) switch allows for manual over-ride of a
door switch if fitted.

The unit should always be switched OFF using the switch box
control, and not by mains power supply interruption.

When the unit is switched off (via the switch box) the fan will run
on for 1 minute without heat to discharge any residual energy
from the heating elements.
When first turned on the control will run through a system check.
The selected settings will be reached and maintained after a 3
minute period.

Door switch control (Electric models)

By including a door switch in the circuit (see ‘D’ in Fig. 6) the air
curtain will respond to door openings as follows:

(1) Door opening will energise the air curtain at the set

conditions (switch box settings).

(2) On door closure operation will continue at the set conditions

for a further 1 minute.

(3) Between 1 minute and 2 minutes from door closure, set

back operation, ½ heat (if heat selected) and ½ fan will
activate.

(4) Between 2 minutes and 3 minutes, the fan only (½ speed)

shut down cycle will be engaged.

(5) After 3 minutes, the air curtain will return to a dormant

state until the door is re-opened.
If the door re-opens during this 3 minute run on cycle, the
process will restart at (1).

Thermal Safety cut outs

The power supply to the heating elements will be interrupted if
one or a combination of the following abnormal events occur:

1. Air inlet or outlet grilles are obstructed.

2. Internal ventilation is impaired due to build up of dust
and fluff.

3. Blower unit stalls.

To reset the thermal safety cut-outs, access reset (red) buttons
(see Fig. 9). Before re-setting the reason for activation must be
determined and corrective action taken.

Low pressure hot water heated / Ambient (fan
only) variants

Operation using switch box - CABC2

Switching the switch marked ‘I’ energises the fan.
The fan switch allows either low or high fan speeds to be
selected.
The A / M (auto / manual) switch allows for manual over-ride of a
door switch if fitted.
The unit should always be switched OFF using the switch box
control, and not by mains power supply interruption.
When first turned on the control will run through a system check.
The selected settings will be reached and maintained after a 3
minute period.

Thermostatic control (optional)

A thermostatic regulation valve with a remote sensing bulb (not
supplied) can be positioned in the supply water pipe-work to
regulate the heat output.

Door switch control (Water heated & Ambient models)

By including a door switch in the circuit (see ‘D’ in Fig. 7) the air
curtain will respond to door openings as follows:
(1) Door opening will energise the air curtain at the set

conditions (switch box settings).

(2) On door closure operation will continue at the set conditions

for a further 1 minute.

(3) Between 1 minute and 2 minutes from door closure ½ fan

set back operation will activate.

(4) After 2 minutes, the air curtain will return to a dormant state

until the door is re-opened. If the door re-opens during this
2 minute run on cycle, the process will re-start at (1).

N - Switch box

For operation via switch box, all BMS switches as shown in Fig. 6
& 7 need to be OPEN CIRCUIT if used. Do not remove BMS links
on PCB.

For operation via BMS, switch box to be set as follows:

I/0 in O (Off) position
Heat selection switch to be in O (Off position)
Fan selection switch in either high or low speed position

O - Circuit Open
1 - Circuit Closed
X - Either Open or Closed

Remote (BMS / BEMS) Operation

Connection to Building Energy Management Control Systems
(BEMS) is possible so that remote control of the air-curtain can
be carried out in conjunction with other equipment.

Modular Connection

A number of units can be connected together to form one
continuous long air curtain. Each appliance should be supplied
separately . Simultaneous control of all the air curtains is achieved
by linking the PCB’s with a modular linking cable found in the
modular linking kit. (Kit Ref. - CABM1) Refer to instructions
provided with the modular linking kit.
