Dimplex DAB15W - Manual (Page 7)

Switch Panel Installation
The backing box (standard double gang) should be rebated into a suitable wall. The
box should be fitted so that the switch panel will be flush with the 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;
OFF - 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
fitted. 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 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 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 effect
- 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 fluff.
3. Blower unit stalls.
To reset the thermal safety cut-outs, access reset buttons as shown in Fig. 9.
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).
Low pressure hot water heated / Ambient (fan only) variants
Operation using switch box - CABC6
Switch on electrical supply to the air curtain. Rotate the switch to the desired heat
setting. Settings available are;
OFF - Low Fan - High Fan
The rocker (auto / manual) switch allows for manual over-ride of a door switch if
fitted. 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 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 30 second period.
Thermostatic control (optional)
1) 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.
2) An electrical 3-Port Solenoid Valve can also be connected into the system. Please
contact your service agent using the contact details for more details.
Door switch control (Water / Ambient models)
By including a door switch in the circuit as shown in Fig. 8 as appropriate, 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 ½ fan set back
operation will activate.
(4) After 2 minutes, the air barrier 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).
