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 fl ow and return pipe-work. Connections (see
'a' in Fig. 5) are: ½ "BSPT (CAB series) and ¾" BSPT (DAB
series) and isolation valves (see 'b' in Fig. 5) should be fi tted
as close to the air barrier connection points as possible. For
commissioning, air bleed valves (see 'c' in Fig. 5) are fi tted to
the coil, which can be accessed by removal of the lower panel
and intake grille - see Fig. 4. The drain (see 'd' in Fig. 5) can
also be accessed when the grille and lower panel is removed.
Maximum water supply conditions are 125ºC and 8 bar.
To aid installation, the water coil connections may be moved
to either side of the appliance. By removing the water coil and
appropriate knockouts the water coil can then be re-inserted
into the required orientation. This procedure should be carried
out before mounting the appliance.
Switch Panel Installation
The backing box (standard double gang) should be
mounted onto a suitable wall. Suitable conduit should be
used where applicable to carry the cable between the
heater and the switch. A CAT5 LAN cable with straight
through connections should be used to connect the switch
panel to the appliance PCB.
Warning: Ensure cable is secure and the cable path does
not come into contact with heater element or other moving
parts. Test all switch settings once installation is complete.
Electrically heated variants
Operation using switch box - CABC5
Switch on electrical supply to the air curtain. Rotate the
switch to the desired heat setting. Settings available are;
  Standby
Low Fan
Low Fan with Low Heat
High Fan
High Fan with Low Heat
High Fan with Full Heat
The rocker (auto / manual) switch allows for manual over-
ride of a door switch if fi tted. Manual allows the appliance
to run at the desire setting, while Auto provides an energy
saving feature by shutting down the appliance while the
door is closed.
The unit should always be switched to Standby using
the switch box control, and not switched off by mains
power supply interruption.
When the unit is switched to Standby (via the switch box)
the fan will run on for 1 minute without heat to discharge
any residual energy from the heating elements. When fi rst
turned on the control will run through a system check. The
selected settings will be reached and maintained after a 30
second period.
Thermostatic control (optional)
By including a single pole bi-metallic or electronic
thermostat to the connections as per 'C' in Fig. 7 the
following functionality is introduced dependant on heat
switch setting.
- Fan only - No eff ect
- Half Heat - Heater will reduce to Fan only
- Full Heat - Heater will reduce to Half Heat
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 fl uff .
3. Blower unit stalls.
To reset the thermal safety cut-outs, access reset buttons
by following the steps below;
IMPORTANT
a.
b. Remove the inlet grilles using a fl at head
screwdriver, loosen both outlet grill screws to
remove the grill ('x' in Fig. 4)
c. Using a Philips head screwdriver, remove the three
M4 screws to remove the bottom panel ('z' in Fig. 4)
d. Locate and remove the two M4 screws located
behind the inlet grills on the lower left and right hand
sides (fi xed to the end caps)
e. Rotate and remove the inlet grill to expose the
safety cut-outs ('t' Fig. 10)
Before re-setting the reason for activation must be
determined and corrective action taken.
Door switch control (Electric models)
By including a door switch in the circuit as per 'D' in Fig. 7,
the air barrier will respond to door openings as follows:
(1) Door opening will energise the air barrier 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).
