Established in the 1960s, Thermoscreens is a leading air curtain manufacturer that exports to over 60
countries worldwide.
As with all our products, the HX CS range of cold store air curtains are designed with energy
efficiency in mind which is why they have fans with advanced EC motor technology to produce a very
high air flow to function in a cold store environment but with low electrical energy consumption.
HX CS cold store air curtains are designed to be surface mounted inside a building and located
horizontally over the doorway between the loading bay and the cold store maintained at minus
temperatures.
They must not be installed on the outside of a building or built into a cabinet or recessed in any way.

HX CS cold store air curtains are designed to be surface mounted inside a building and located
horizontally over the doorway between the loading bay and the cold store which is maintained at
minus temperatures. It must not be installed outside of the building.
7.1Location
Mount the air curtain above the doorway, with:
the discharge grille not more than 4m above floor level
at least 100mm clearance above the air curtain, see Fig 1
with the back edge of the hanging bracket 100mm from the doorway,
so the air curtain can swivel, see Fig 1, Figs 2a and 2b.
Beware of doorway top edges, structural beams, door opening/closure
devices, etc., which may interfere with the air stream and affect the location of
the unit.
7. INSTALLATION
NOTE: For the air curtain to work well the width of the open doorway should be less than the
effective width of the airstream, see Table 1.

7.2 Ceiling Suspension
M10 Threaded rods (not supplied) are used to suspend the unit from
the ceiling.
Suspend the unit from the ceiling as follows:
Step 1 Locate Ceiling Hanging Brackets to each side of the air
curtain as shown in Fig 3.
Step 2 Fit two M12 bolts from inside the air curtain to secure each
Ceiling Bracket. The top bolt is `fitted through a slot which
allows the air curtain to be tilted.
Step 3 Fit and secure M10 threaded hanging rods into holes on the
top face of each Ceiling Bracket.
Step 4 Secure all hanging rods (x4) to a suitable structure that can
support the weight of the unit (see section 3: Specifications
for weights).
Step 5 Tighten all fixing bolts until the air curtain is safely secured.
7.3 Wall Fixing
Step 1 Drill fixing points in the wall, referring to Appendix 1 for correct positioning. Using suitable
fixing bolts, fix both wall brackets to the wall.
Step 2 Locate Ceiling Hanging Brackets to each side of the air curtain as shown in Fig 3.
Step 3 Fit two M12 bolts from inside the air curtain to secure each Ceiling Bracket. The top bolt is
fitted through a slot which allows the air curtain to be tilted.
Step 4 Air curtain can be fitted directly to Ceiling Hanging Brackets using M10 nuts and bolts.
Alternatively, using M10 threaded hanging rods air curtain can be fitted to Ceiling Brackets
(see Appendix 1).
Step 5 Tighten all fixing bolts until the air curtain is safely secured to the wall.
NOTE: Use suitable wall fixing bolts (not supplied) to fix the unit to the wall, taking into account the
type of wall and the weight of the unit (see section 3: Specifications).
WARNING: It is the sole responsibility of the installer to ensure that the fixing locations and
suspension system used are suitable for the air curtain being installed.

8.1 How to access terminals
To gain access to the air curtain for connection and commissioning, remove air inlet grilles and
bottom access panel as explained below.
First remove the plastic end caps at each end of the unit, if fitted, by pulling off to the side.
8.1.1 Remove air inlet grilles
Using a Pozi No 1 screwdriver, remove each grill with its filter.
To remove, insert screwdriver into the elongated hole at the bottom
corner of the grille (see Fig 5) and turn the screw one quarter of a turn
anticlockwise.
8.1.2 Remove bottom access panel and access terminals
Unfasten the securing screw at each end (see 1, Fig 6) and, if
applicable, two screws in the centre (HX1500 and HX2000 units only).
To remove, slide the access panel (see 2, Fig 6) out forwards.
Remove the control box upper lid cover (see Fig 7).
Connect electrical supply from local isolator as shown in Fig 8.
Refer to Appendix 2 and 3 for Wiring Diagrams.
8. ACCESS FOR ELECTRICAL CONNECTION
NOTE: All air curtain panels are protected in a plastic film. When access panels are removed this
film can be removed.

8.2 Door Switch Connection
For an optional door switch to be fitted, remove link fitted to
terminals 6 and 7 (see Fig 9) and connect switch to these
terminals (see Appendix 1).
If two air curtains are required on the same doorway (i.e.
master/slave), connect an additional trigger signal wire from
master terminal 7 (see Fig 10) to slave terminal 7.
8.3 Fan Speed Selection
Set a suitable fan speed by adjusting the EC speed potentiometer
(see Fig 11) to suit outdoor environmental conditions and indoor
noise levels.
8.4 Off Timer Delay Settings
The Off Timer Delay is factory set to 24 seconds with time and
adjustment ranges set to 0.4 and 1. The function setting dial is
set to R (OFF delay), as shown in Fig 12.

T9901108-1-1 UK Page | 10
9.1 Verify system operation
To commission the system, verify the following conditions are met:
All fans are working.
The door switch (if fitted) correctly starts the fans when the doors open.
The timer relay keeps the fans running for the specified time (factory default is 24 seconds).
Fan speed changes in accordance to the speed dial fixed within the unit (as shown in Fig 11).
There is no excessive mechanical noise coming from the fans..
9.2 Instruct customer and hand over
Before leaving site, hand over the installation to the customer/end user or their representative.
Explain that any person operating the air curtain must be given supervision and instruction by the
person responsible for their safety, concerning the safe use of the unit and to understand any hazards
involved. Children and those with reduced physical, sensory or mental capabilities should not operate
the air curtain.
Recommend that the doorway should be closed whenever possible but that during times of high
traffic it will become an ‘open doorway’. The air curtain then serves an essential purpose of reducing
the energy needed to maintain the internal temperatures.
Explain that the inlet grilles must be cleaned regularly and the unit serviced at schedule intervals –
see section 12: Service & Maintenance.
Complete the following once commissioning is completed.

11.1 Fuses
In the event of an electrical fault check the fuses. The Control Box within the air curtain is fitted with a
5 x 20mm cartridge anti-surge 5A fuse. See Wirings Diagrams in Appendix 2 and 3.
The motors are also fitted with internal thermal overload protection that under normal operation
shouldn’t activate. If you find they have, refer to the Warranty section at the end of this set of
instructions.
12.1 Every week
Turn off the air curtain to prevent entry of contaminants then wipe clean the face of the air inlet grilles.
12.2 Every 3 months
Clean and inspect the inside of the air curtain as follows:
Step 1 Remove plastic end caps at each end of the unit by pulling off to the side.
Step 2 Use a Pozi No.1 screwdriver to remove air inlet grilles by releasing the quarter-turn
fasteners at the bottom corners of each air inlet grille.
Step 3 Wipe clean to remove any build-up of dust and dirt within the air-curtain (inlet/outlet grilles,
fan impellers, housings and motors).
Step 4 Check within the unit to ensure all electrical connections and crimped terminals are tight
and that all cables are in good condition. Pay special attention to the edges of the
electrical boxes to ensure they aren’t damaged that would lead to water ingress.
Reconnect electrical supply and test to ensure correct operation (see Section 9: Commissioning).
11. FAULT CONDITIONS
12. SERVICE & MAINTENANCE
NOTE: Weekly maintenance can be carried out by anyone who has access (at height) to the unit.
NOTE: Build-up of dirt on fan impellers can cause vibration, noise and excessive wear on the
motor bearings.
WARNING: Failure to adequately maintain the unit and provide a suitable cleaning schedule will
result in a loss of performance and reduced life expectancy of the air-curtain.
WARNING: Before servicing, isolate and disconnect the air curtain from the electrical power.
WARNING: The following servicing and maintenance must be carried out by a competent
electrician or a Thermoscreens appointed technician.
