4. INTRODUCTION
Established in the 1960s, Thermoscreens is a leading air curtain manufacturer that exports to over 60
countries worldwide.
As with all our products, the T recessed range of air curtains are designed with energy efficiency in mind.
T models suffixed ER, WR or AR are designed to be recess mounted inside a building and located
horizontally over a doorway.
They must not be installed on the outside of a building.

7. INSTALLATION
The air curtain is designed to be recessed within ceiling voids or bulkheads with in a building and
located horizontally over a doorway. It must not be installed outside of the building.
7.1 Location
Mount the air curtain above and as close to the doorway as
possible, with:
the recesse d grille not more than 3m above floor
level
the air discharge (see 1, Fig 1) section of the
recessed grille nearest the doorway and the air inlet
section (see 2, Fig 1) furthest from the doorway
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.
NOTE: For the air curtain to work well the doorway should be less than the width of the airstream.
7.2 Ceiling Suspension
Step 1 Depending on whether a standard or wider width
recessed grille is used, cut an aperture in the ceiling
to the dimensions in Appendices 1. Cut notches, if
necessary, to clear screws in the air curtain casing.
NOTE: For LPHW models, pipework will need to be installed
Step 2 Fix M10 threaded rods (not supplied) through the 2
NOTE: Do not let the hanging rods come below the bottom
above the curtain. Allow sufficient access and height
clearance within the ceiling void to do this.
holes at each end in the top casing (see Fig 2). Feed
the rods through the casing and attach to fixing
brackets near the bottom of the unit (see Fig 3,
looking up into the air curtain). Use M10 lock-nuts
either side of fixing brackets to secure hanging rods.
An additional threaded rod is fitted on a 1.5m unit with
two extra threaded rods fitted on a 2m unit, see
Appendices 1.
of the unit casing or they may prevent the recessed
grille fitting properly.

M10 threaded rod into the hanging point in the middle
and 6th threaded rods, see Appendices 1 and Fig 4.
Step 4 Secure each rod to a suitable structure that can support the weight of the unit (see section 3:
Specifications for weights).
Step 5 Adjust the height of the unit on its hangi ng rods so the bottom surface of the casing goes
between 25-50mm up into the ceiling as shown in Fig 4. Ensure the unit is level.
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.
7.3 Attaching the recessed grille to the air curtain
The recessed grille consists of:
Metal frame
Hinged standard or wider width inlet/discharge grille
Slotted fixing brackets
There are 4 fixing slotted brackets on the T1000R with 6 brackets fitted on T1500R and T2000R (see
Fig 5a and Fig 5b).

T9901012-1-1 UK (v9) Page | 7
Fix the grille as follows:
Step 1 Open the hinged inlet grille using a flat bladed
screwdriver to release the quarter turn fasteners
(see Fig 6). There are two fasteners on the
T1000R unit and three fasteners on T1500R and
T2000R units. Before lifting the grille frame into
position, remove four (six on T1500R/T2000R)
M6 bolts fitted on the inside edge of air curtain.
Step 2 Make sure the grille will go the correct way
around (discharge nearest to doorway). Offer
the recessed grille up through the cut-out in
the ceiling.
Step 3 Using the M6 bolts removed in Step 1, secure
grille by fixing each bolt through the slotted
brackets as shown in Fig 8. For illustration
purposes Fig 8 details a wider recess grille.
With the hinged grille open, adjust the height of
the grille frame via slots in each bracket, so
frame is snug fit against the ceiling with no
gaps all the way around.
Step 4 To stop discharge air re-circulating within the
air curtain a sliding separator will need
adjusting up or down (see Fig 9). To adjust
plate release M6 bolts either end, extend the
slide plate so that it will touch the topside of
the grille along its whole length and tighten the
bolts. It will be necessary to close the hinged
grille core to gauge where the separator plate
should be fitted.
Step 5 Once the above steps are complete the
hinged grille core can be closed and all the
quarter turn fasteners tightened up.

NOTE: Open the hinged grille core to gain access to
electrical connections, and for servicing and
maintenance.

8. LPHW MODELS
For LPHW models ensure that water isolation valves are fitted in the flow and return pipework
adjacent to the air curtain and connected correctly as shown in the diagram in Appendix 1.
For the design of the water pipework system and pump, water flow rates and pressure drops for
maximum heat output of the air curtain are given in Table 2 below.

NOTE: Water Pressure Drop is across the flow and return pipework to the air curtain and includes for the
coil fitted inside the unit and the valve fitted in the heating pipework to the unit.
Water flow rates and pressure drops at different water temperatures can be calculated using the
Thermoscreens coil calculation programme. Visit the Thermoscreens website for details.
The installer must connect the 3-port valve in the heating pipework as shown in Figure 11 below:
