 Thermoscreens Jet 6 Drive-Thru Air Curtain [DTAC] unit
 Mounting bracket [MB] c/w fixing hardware
 Cable gland
For warranty purposes please retain your receipt as proof of purchase.
INSTALLATION
The DTAC is designed for surface mounting horizontally at a discharge
height level to the sliding window header. Multiple DTACs mounted
side by side may be used for wider openings. The DTAC must be
mounted directly to the MB. The DTAC must not be located
immediately below a socket outlet. DO NOT INSTALL BOTTOM OF
HEATER LESS THAN 550mm ABOVE PLATFORM.
Figure 2: Window Header Mounting Guide
Before fitting DTAC, locate mounting hardware as necessary taking into
account the window header design and unit weight (see Table 1). Using
the MB as a template, determine an optimum location for the DTAC,
place the MB on the target location, mark position of the fixing holes to
be drilled. Using suitable fixing hardware, install the MB as required into
position. Some internal header components may have to be moved
before any drilling is conducted; it may be necessary to drill up from the
header due to design configuration of the window clearance.
Figure 3: Mounting Bracket Alignment
Align and position mounting bracket into the two slots on the rear plate
of the DTAC (refer to Figure 3). Ensure the serrated washer, at each
end of the DTAC, is positioned between the mounting bracket and the
internal hanging bracket (see Figure 4). Tilt and point DTAC into the
preferred direction and firmly tighten both fixing screws. Using a
Philips No. 2 screwdriver the fixing screws are tightened via access
hole in each end cap.

ELECTRICAL CONNECTION

Ensure that the supply cables, circuit breakers and other electrical
installation equipment are correctly sized for the
DTAC being installed, see Table 1. For each DTAC a single phase local
isolator with a contact separation on both poles of at least 3mm must be
fitted to the supply wiring (the isolator must be fitted within an
accessible position). The DTAC should be connected to a 208V 2-pole
AC 60Hz electrical supply and must be earthed. Remove the two outer
M4 x 12mm pan head Philips screws atop the DTAC and release the
power connector plate. Fit cable gland to power connector plate. Insert
electrical supply cable via cable gland (see Figure 5) and tighten gland
around cable.
Figure 5: Electrical Connection
Connect each of the cables as follows:
 Live brown cable to terminal marked L or L1
 Neutral blue cable to terminal marked N or L2
 Earth green/yellow cable to terminal marked PE
Position the electrical supply cables as they come out of the terminal
block as shown in Figure 5. Ensure only sufficient cable is pulled
through to enable connection to terminal block and to avoid excess
cable coming into contact with any moving parts. Carefully insert all
cables through the rectangular hole in the top of the DTAC and refit the
power connector plate. Ensure mains supply cable is correctly and
sufficiently strained by the plastic cable gland.

installation and these instructions are “Handed-Over” to the end user or
their representative and the operation of it is fully explained and that
they understand how it operates.
THERMAL SAFETY CUT
-
OUTS
If the DTAC exceeds normal operating temperature the thermal safety
cut-outs will operate and isolate electrical supply to the heating
elements. Thermoscreens recommend only competent qualified
persons service the DTAC.
To reset the thermal safety cut-outs disconnect electrical supply to the
DTAC, determine and resolve the cause of the fault. Allow DTAC
sufficient time to cool before restoring supply. If the fault persists
arrange for a competent technician to attend site and investigate. In
order to avoid a hazard due to inadvertent resetting of the thermal cut-
out, this appliance must not be supplied through an external switching
device, such as a timer, or connected to a circuit that is regularly
switched on and off by the utility.
SERVICE
&
MAINTENANCE
Always disconnect and isolate the main electrical supply before
installing, maintaining or repairing this equipment. All
maintenance/repairs should only be carried out by a competent
electrician or Thermoscreens appointed technician. To ensure the
DTAC operates efficiently, the air inlet and outlet grilles, fan impellers,
housings and motors must be kept free of dust and debris. Regularly
vacuum and clean any build-up of dirt and debris within the DTAC
(please note that the motor is permanently lubricated and require no
additional lubrication). Once the DTAC has been cleaned check all
electrical connections within the unit ensuring terminals are tight and
that crimped connections have not become loose. If the outer casing
requires cleaning this should be carefully done using a warm soft cloth.
Do not use solvents or abrasive materials. Reconnect the electrical
supply and fully function test the DTAC to ensure correct operation.
WARRANTY
If any problems are encountered, please contact your installer or
supplier. All units are covered by a one year warranty. Subject to
availability we undertake to repair or exchange this product.
Care has been taken in compiling these instructions to ensure they are
correct, although Thermoscreens disclaims all liability for damage
