Electrical
The installation of this appliance should be carried out by a
competent electrician and be in accordance with the current IEE
wiring regulations.
Installation
This appliance may be either wall-mounted or fixed to a ceiling -
see Fig. 3a & 3b for fixing positions and ‘Mounting’ sections
below for fixing details.
A minimum distance of 500mm is required from the top of the
appliance to ceiling - see ‘a’ in Fig. 1.
The distance between the bottom of the appliance and the top of
a door should be kept to a minimum - see ‘b’ in Fig. 1.
Wall Mounting
A suitable load bearing structure (not supplied) is required to
wall mount the appliance, see Fig. 3a. (see Fig. 6 for fixing
dimensions).
Ceiling Mounting
Lift the appliance into position using suitable lifting equipment.
(You may use the pallet supplied with the unit). Secure the
appliance into position using M12 threaded bar and locknuts as
shown in Fig. 3b (see Fig. 6 for fixing dimensions).
Dimplex Industrial Air Curtains
Models : IAB10E, IAB15E, IAB10W, IAB15W, IAB10A, & IAB15A
Electrical connection
All products are fitted with a microprocessor control. Electrical
power and control connections are made as shown in Fig. 2. 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 air
supply grille (‘g’ in Fig. 2) and the front panel (‘f’ in Fig. 2).
Feed an appropriate supply cable (see ‘e’ in Fig. 2) through a
suitable cable gland (not supplied) fitted in the top panel and
attach to the Mains In Terminal Block (see ‘d’ in Fig. 2).
A suitable cable for the supplied switch panel can be similarly
introduced 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 as per Fig. 4 & 5 as appropriate - see
also ‘Switch Panel Instructions’.
If the unit is to be connected to a Building Energy Management
System, connections are made as per ‘G’ in Fig. 4 & 5 as
appropriate.
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. 2) are: 1” BSPT and isolation valves (see ‘b’ in Fig. 2) should
be fitted as close to the air curtain connection points as possible.
For commissioning, air bleed valves (see ‘c’ in Fig. 2) are fitted
to the coil, which can be accessed from outside the unit.
Maximum water supply conditions are 110ºC and 10 bar
(1MPa).
Ensure that the air curtain is securely fastened in position and
that the supply cables are firmly clamped before operating the
appliance.
Operation using Switch Panel
Electrically heated variants
When first turned on the control will run through a system check.
The selected settings will be reached and maintained after a
one minute period.
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 panel
control, and not by mains power supply interruption.
When the unit is switched off (via the switch panel) the fan will
run on for 1 minute without heat to discharge any residual energy
from the heating elements.
Door switch control
By including a door switch in the circuit (as per ‘D’ in Fig. 5) the
air curtain will respond to door openings as follows:
(1) Door opening will energise the air curtain at the set
conditions (switch panel 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 positioned under the air
inlet grille (‘g’ in Fig. 2), first turn off power to unit before pressing
the red reset buttons. Also check the position of the 16A MCB.
Before re-setting the reason for activation must be determined
and corrective action taken.
Low pressure hot water heated and Ambient (fan
only) variants
When first turned on the control will run through a system check.
The selected settings will be reached and maintained after a
one minute period.
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 panel
control, and not by mains power supply interruption.
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
By including a door switch in the circuit (as per ‘D’ in Fig. 4) the
air curtain will respond to door openings as follows:
(1) Door opening will energise the air curtain at the set
conditions (switch panel 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).
Motor protection
The blower units are protected by a 16A MCB and by thermal
fuses.
If there is an electrical fault, the MCB will trip. Before resetting
the reason for actuation must be determined and corrective
action taken. If a thermal fuse operates, the appliance may cycle
on and off. The appliance should be switched off and the reason
for activation corrected.
