Electrical Supply and Wiring to the Air Curtain

All electrical wiring and connections MUST be carried out by a competent qualified electrician in

accordance with the latest edition of IEE wiring regulations and local statutory regulations if applicable.

A 1 phase or 3 phase local isolator having a contact separation of at least 3mm on all poles

must be fitted in the electrical supply to the air curtain and located in an accessible position

adjacent to the unit.

The appliance must be connected by cables having an appropriate heat resistant temperature

rating.

All supply cables, circuit breakers and other electrical installation equipment must be correctly

sized for the air curtain model being installed; see Section 3: Specifications.

Models operating on a 3 phase electrical supply - see Section 3: Specifications - require a

neutral connection (3N~).

A 25mm size cable gland or conduit connector of IP21 rating or above should be used for the

Electrical Supply into the air curtain.

See Wiring Diagrams for connecting electrical supply and control cables to the air curtain. The

air curtain must be earthed.

Established in the 1960s, Thermoscreens is a leading air curtain manufacturer that exports to over 60

countries worldwide.

As with all our products, the PHV range of air curtains is designed with energy efficiency in mind.

PHV models suffixed E, W or A are designed to be surface mounted inside a building and located

horizontally over a doorway.

They must not be installed on the outside of a building or built into a cabinet or recessed in any way.

The air curtain is designed to be 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 discharge grille not more than 4m above floor level

at least 100mm clearance (air gap) above electric/water

heated air curtains, see Fig 1

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.

7.2 Wall Fixing

Step 1 Bolt all wall brackets to the rear face of the unit

as shown in Fig 2, using the M6 fixing bolts

supplied.

Step 2 Drill fixing points in the wall, referring to

Appendix 1 for correct positioning.

Step 3 Screw in the top wall bolts leaving a small gap

between the screw head and the wall.

Step 4 Lower the unit onto the bolts via the key-hole

slots in the top of the wall brackets and screw in

the bottom wall bolts.

Step 5 Tighten all fixing bolts until the air curtain is

safely secured to the wall.

7. INSTALLATION

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).

NOTE: For the air curtain to work well the width of the open doorway should be less than the length

‘A’ of the air curtain, see Appendix 1.

7.3 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 Screw the threaded rods into all of the holes in the

top face of the unit as shown in Fig 3.

Step 2 Fit M10 locking nuts (not provided) to prevent the

rod rotating and coming away from the casing.

Step 3 Secure each suspension rod to a suitable structure that can support the weight of the unit (see

section 3: Specifications for weights).

7.4 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.

PHV1500W, 3-row (18kW) 12.9 10.0

PHV2000W, 3-row (24kW) 17.1 18.3

NOTE: Do not screw hanging rods too far in as they

could interfere with internal components.

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.

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.

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

Unfasten the securing screw at each end (see 1, Fig 6) and, if

applicable, two screws in the centre (PHV1500 and PHV2000 units

only).

To remove, slide the access panel (see 2, Fig 6) out forwards.

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.

Mount the Ecopower remote control in a convenient position directly to the wall or onto a switch box.

9.1 Wall mounting

Step 1 Using a screwdriver undo the screw on the top of the remote control

case and pull the back case away (see Fig 7).

Step 2 Feed one end of the RJ control cable through the back case, secure it,

then screw the back case to the wall using suitable fixings (not

supplied).

Step 3 Connect the RJ plug to the RJ socket on the PCB in the remote control.

Step 4 Refit the front case.

9.2 Switch box mounting

Step 1 Using a screwdriver undo the screw on the top of the remote control case and pull the back

case away (see Fig 7).

Step 2 Feed one end of the RJ control cable through the switch box, feed and

secure the RJ control cable through the back case and secure back

case to switch box using 2 mounting screws (not supplied) (see Fig 8).

Step 3 Connect the RJ plug to the RJ socket on the PCB in the remote

control.

Step 4 Refit the front case.

On the back of the PCB inside the Ecopower Remote Control you will find four DIP switches that

provide the following optional features, see Table 3:

DIP Feature Explanation Default Notes

11.1 Remote switch contacts IN0, IN1

Terminals IN0 and IN1 on the Ecopower PCB inside the air

curtain can be used to provide different control strategies

using remote volt-free contacts (see Fig 9). This could be to

provide remote On/Off from a timer or BMS Digital/Output

contact, to work with a door switch or for simple weather

compensation control to disable heating when outdoor air

temperatures become warmer. Table 4 describes the

different functions:

Table 4

WARNING: Do not apply any voltage to terminals IN0 and IN1 as this will damage the Ecopower

PCB inside the air curtain.

NOTE: Wire volt-free, remote switch contacts to 2-way screw terminals IN0 and IN1 using 2-core

cable.

* NOTE: The Ecopower Remote Control must stay plugged-in for the air curtain to keep working.

An optional plug-in EEPROM is available from Thermoscreens so the Remote Control can be un-

plugged and the air curtain stay working. Visit the Thermoscreens website for details.
