INSTALLATION OF YOUR VERTICAL APPLICATION PHV V NT AIR CURTAIN

The air curtain must be surface mounted within the building and not exposed to

the external environment or moist conditions. Do not install the air curtain in a

doorway situation where there is a likelihood, or there has been a history of, rain

ingress. The air curtain must not be built into a compartment or recessed.

Location

Prior to commencing any vertical installation it is essential to ensure the correct handing
has been selected, i.e. Left Hand (LH) or Right Hand (RH) - . see “Handing Guide” in
Figure 1. Maximum doorway width = 2m per air curtain.

The air curtain should be located close to the door opening with the air discharge grille
positioned nearest to the door. For maximum effectiveness it is essential to ensure the
top of the air curtain is slightly higher than the opening height of the door. Obstructions
such as door opening devices, structural beams etc will reduce the efficiency of the air
curtain.

Floor Fixing

Before installing the air curtain obtain four suitable M10 fixing bolts, taking into account
floor type and unit weight (See Table 1)*. Rawlplug ® M10 Projecting Rawlbolt ® 44356
type may be suitable. For dimensional details refer to the general assembly drawing,
Figure 1.

Determine and place the unit in position. A wall bracket is provided to secure the
vertical air curtain to the wall and this must be used. So that the wall bracket touches
the wall, ensure the back of the base plate touches against the wall, skirting board will
need to be cut away if necessary.

Using the base plate as a template, mark the location
of the four holes, as indicated in the adjacent picture.

Using a suitable masonry drill bit correctly drill the
four marked out holes. Place M10 fixing bolts into
each hole, ensuring all bolts are upright.

Reposition the air curtain base plate over the
projecting bolts. Tighten each M10 nut as indicated
in the adjacent picture. Ensure the vertical unit is
secure, level and square. It may be necessary to
pack under the base plate to ensure unit is vertical.

Using a hacksaw carefully cut the projecting bolt
flush with the nut, ensuring the base plate is not
damaged or marked in any way.

Remove only one M10 nut and refit and resecure bolt
with a stainless steel M10 dome nut supplied.
Repeat for each of the other three projecting bolts
one at a time.

Stacking of Units

PHV1500V and PHV2000V air curtains are delivered as single units. PHV2500V and
PHV3000V air curtains are delivered as separate 1.5m + 1m air curtains for a
PHV2500V unit and 2m + 1m air curtains for a PHV3000V unit. The 1m air curtain
must always be mounted as the top unit using the stacking kit supplied to secure it to
the bottom unit. The spacer plate, in the stacking kit must be bolted between the two
units using the 4 off M8 x 25 bolts and nyloc nuts. This will allow the removal of
access panels when required. All wall brackets must be used to properly secure both
the bottom and top air curtains in the stack to the wall (See Figure 1).

* It is the sole responsibility of the installer to ensure that all the fixing points and bolts
used are suitable for the air curtain.

Attention: The panels of the air curtain are coated in an easy to peel protective
film. Please ensure all the protective film is removed before the air curtain is put
into service.

Safety and Electrical Connections

All electrical wiring and connections MUST be carried out by a competent qualified
electrician in accordance with the latest edition of the IEE wiring regulations and/or
local statutory regulations.

A single phase or 3 phase local isolator with a contact separation of at least 3mm in all

poles must be fitted to the supply wiring (the isolator must be fitted in an accessible

position).
The air curtain must be earthed.
The appliance must be connected using cables having an appropriate

temperature rating (heat resistant). For two air curtains in a stack, electrical power must

be connected separately to the bottom air curtain and to the top air curtain.
Ensure that the supply cables, circuit breakers and other electrical installation

equipment are correctly sized for the air curtain being installed; see Table 1 for Power

Ratings. See also data badge inside of unit adjacent to electrical inlet.
On a 3 phase electrical supply the unit requires a neutral connection (3N~).
Cable glands used for the Electrical Input must be rated IP21 or higher.

To gain access for making electrical and/or water
services the air intake grilles must be removed.
Remove intake grilles by unfastening two screws
on each grille; M4 x 10mm Pozi screws accessed
via larger hole in the side of the grille (See
Insert).

Access can now be gained to make the electrical
connections and assist with water connections.

When making electrical connections first remove
the safety cover plates over the electrical supply
terminals. On 2m electric air curtains the safety
cover plates are located towards the centre of
the air curtain (See Insert).

For two air curtains in a stack electrical and
water connections are made separately to the
bottom air curtain and to the top air curtain
(See Figure 1 View B).

Fitting/Connecting the Ecopower Remote Control

The remote control unit should be located in
a suitable place for easy access, it can be
fixed to the wall via two key-hole slots. Drill
and fix the screws into the wall leaving a
small gap between the head and the wall,
lower the unit onto the screws, for fixing
centres see adjacent figure. Ensure suitable
fixing screws are used.

The remote control is supplied with cable and
a pre-fitted RJ connecting plug.

Ensure the remote control cable is safely
secured and connected to the air curtain as
indicated. It can be plugged into either
socket.

Two Air Curtains in a Stack

When two air curtains are in a 2.5m or
3m stack the Ecopower control wiring
needs to be wired “master/slave”, so the
air curtain stack is controlled by a single
Ecopower remote control.

Plug the control cable from the remote
control into one of the RJ sockets at the
side of the top air curtain.

Inside the air curtain stack connect the
RJ master/slave cable that is already
plugged into the top unit circuit board,
into the Ecopower PCB of the bottom
unit. Route the RJ master/slave cable
safely via the hole in the stacking kit
(Refer to Figure 2).
