DESCRIPTION
The Stratum Homelift is an inter floor lift that is designed for use
by persons with impaired mobility travelling between fixed floor
levels in private dwellings.
With a maximum carrying capacity of one person, with or
without a wheelchair (or 250kg), this lift is not intended for use
as a means of transporting goods.
The lift is designed to operate without a lift shaft and is provided
with an automatic in fill panel which makes the ceiling aperture
safe when the lift is parked downstairs.
Two way communication system should be specified for
emergency communication.
A standard feature is the provision of half hour fire rated panels
in both the aperture in fill and the car underpan.
The lift car panels are made from powder coated steel which can
easily be cleaned using normal household cleaners. Upholstery is
made from PVC and can be cleaned in the same way.
A smoke detection system has been installed on your lift. It has
been designed to provide adherence to British Standard BS5900
2012 Section 9.13 “Behaviour of homelift in the event of fire”.

GENERAL DOS AND DON’TS
• Never switch off the power supply to the lift, even when you go
away. The lift control circuits are fed by a battery, which must be
kept on constant charge.
• The lift should always be returned to the lower level when not in
use. If it is left upstairs for prolonged periods, it will occasionally
re-level itself depending on conditions. The lift must be left at
the lower level if the mains is turned off.
• If your lift is fitted with a manual door always close it after use.
Powered door units have a self closer. Do not pull or push the
automatic door.
• Never allow children to play in, under or around the lift. If
children are in the house, isolate the lift using the optional
remote isolate fob, (page 7).
• Ensure that the area under the lift is kept clear. The underpan
safe surface is fitted with sensors, which automatically stop the
lift if it strikes an object (page 6).
• Always keep your emergency door release key and optional
remote isolate fob in the lift or in a safe place near the lift.
• Do not place any object on the aperture infill panel safe edge
or stand on it when the lift is in operation. Ensure that as far as
practical, the area around the travelling infill panel safe edge
is clear of persons (particularly children) when the lift is being
operated. This is to ensure there is no danger of them falling
into the car when the lift is in use. The infill panel safe edge
is fitted with sensors that automatically stop the lift if the infill
panel is obstructed (page 6)
• Do not use this lift for anything other than transporting those
with impaired mobility between fixed floor levels
• Do not lean over the car sides or door. These are fitted with
safety edges which will stop the lift if activated.
• Always treat your lift with respect that should be shown to
electrical and mechanical equipment.

• Users with wheelchairs should apply the brakes on their
chair and all other users should ensure they are using the seat
provided before moving the lift. Do not travel in the lift unless
seated.
• Safety related components should only be adjusted and reset by
a competent person.
• Proceed with caution when exiting the carriage backwards.
The diagram below (Figure 1) shows the position of all the
sensors on the lift, designed to prevent injury or damage if the
movement of the carriage is obstructed.

CONTROLS AND OPERATION
There are two wall mounted call stations, one at each level
(Figure 2) and a similar control station fitted in the lift car. The lift
can be isolated by using the optional remote isolate fob (Figure
3). When the lift is isolated, none of the control stations will
function. The call and control stations can only be activated by
using the optional remote isolate fob. When the lift is activated,
the coloured indicator lights in the car will illuminate. The lights
in the car will switch on automatically when any call or control
button is pressed and will automatically turn off after a few
minutes.
Once the lift has been stopped it cannot be restarted for 3
seconds.

Users with wheelchairs should apply the brakes on their chair
and all other users should ensure they are using the seat
provided before starting the lift.

General operation
Call the lift by pressing the up arrow or down arrow button
on either call station and wait for it to stop. The door will
automatically open. Enter the lift and press and release the
door button to close it. Then press and release UP or DOWN on
the control station. The lift will travel uninterrupted to the next
floor. If the lift does not start, check that the door is properly
closed and try again. Always close the door after using the lift by
pressing the door button on the wall mounted call station. Leave
the lift downstairs whenever possible.
In the event that the normal controls fail to work, emergency
controls can be found under the flap above the mirror. Green is
‘UP’, red is ‘STOP’, black is ‘DOWN’ and white is ‘DOOR’ (Figure
4).

When outside the car, in an emergency the door can be opened
by pressing the front end of the side safe edge, on the corner
where the door opens (Figure 5).

SMOKE ALARM
A smoke detection system has been installed on your lift. It has
been designed to provide adherence to British Standard BS5900
2012 Section 9.13 “Behaviour of homelift in the event of fire”.
The system utilises two smoke alarms one upper level, one lower
level, which are wirelessly connected to the main circuit board on
the lift (Figure 6).
Figure 6.
The Smoke Alarm unit comprises two parts, the first (TOP PART)
being a Smoke alarm unit. This is the Smoke detection unit and
contains an integral battery with a 10 year life span. This is not
replaceable.
The second part (BASE UNIT) contains the radio transmitter
receiver unit. Power to this unit is supplied by single 10 year life
span lithium battery.
Radio smoke alarm operation
When installed on a Harmony Lift, the smoke alarm system will
cause the lift to deactivate safely once the alarm is triggered.
When the lift is deactivated, the door will continue to operate as
normal.

When the Lift is stationary at either level
If smoke is detected, the alarm will sound. After a period of time,
all other smoke alarms connected to the system will then start to
sound and the lift deactivates.
When the Lift is travelling between levels
If smoke is detected, the alarm will sound. After a period of time,
all other smoke alarms connected to the system will then start to
sound.
The lift will continue to its requested level, it will remain possible
(until that level is reached) to change the direction of the lift.
Once at the desired level, the lift will deactivate.
Reactivation of Lift
The lift will automatically reactivate when the smoke alarm no
longer detects smoke and a period of two minutes has expired.
Silencing the Smoke Alarms
The alarms can be silenced by pressing the mute button on
the sensor that initiated the alarm. The initiating sensor can be
identified by a Red light flashing every second.
When the alarms are deactivated, the lift will automatically
reactivate when a period of two minutes has expired.If the source
of the smoke alarm is not removed, the smoke alarms will begin
to sound again and the lift will be disabled.

11
EMERGENCY PROCEDURES
In the event of a mains failure during travel, the battery backed
control system of the lift will only allow normal operation in the
down direction without loss of any safety features. This allows
the user to exit the car at the lower level in the normal way.
Emergency Manual Lowering
IMPORTANT:
During emergency manual lowering, the normal safety features
will not function, so the lift will not stop if a person, pet or object
is under the lift.
• The exact lowering procedure must be observed, because the
normal safety features will not function during manual lowering.
• The emergency lowering procedures should never be used if the
lift is fully up or no one is trapped in it.
• The emergency lowering procedures should never be used as
the normal down travel function until an engineer attends.
PLEASE NOTE:
If the lift is fully upstairs and a person is trapped inside, please
see the section Emergency unlocking on pages 12-13
If the lift has stopped mid level and the customer is unable to get
the lift up or down then the only time it should be lowered by the
emergency valve is if:
• There is a second person (B) around the lift area at the lower
level to ensure that nothing goes under the lift during the
lowering by the first person (A)
• OR the person lowering the lift has sight of the area under the
lift
Person A
• Ensure the door is fully closed
• Turn the mains supply to the lift off.
• Locate the hydraulic power unit, normally outside the property
(Figure 7)

12
• Swivel the metal cover plate on the front face of the housing to
reveal an access hole (Figure 7)
• The red cord revealed in the access hole now needs to be
pulled continuously to lower the lift car slowly.
• After 5 seconds release cord and check with person B that the
aperture infill panel is following the carriage. If so, resume
pulling the cord as before.
• Once the lift is at the lower level turn the mains supply back on
and secure metal cover plate.
Figure 7.
Person B
Remains in the house by the lift and communicates with Person
A to ensure the safe lowering of the lift.
• Ensure that no object, person or pet are in the path of the lift
travel
• Confirms that the trap door follows the lift during descent
and locates fully in the floor to guard against the possibility of
anyone falling down the lift way.
Emergency unlocking
WARNING: RISK OF FALLING – Emergency unlocking must
only be undertaken when the lift is at the upper or lower
landing level.
The lift car door is designed so that it will only open when the lift
is at or within 25mm of each floor served. If for any reason the
door cannot be opened, the door lock can be over-ridden from the
inside using the following steps:
Remove the screw using the
screwdriver provided at installation.
Swivel this metal cover plate to one
side in order to gain access to the
lowering cord behind the plate.

13
a Remove the black rubber grommet by the door
b Insert the black emergency door release key into the square
hole behind the grommet
c Turn the key to release the mechanism
This should release the catch. The door can be opened from the
outside in the same way.
The electrically operated door on the wheelchair model can be
forced open or closed manually. This will disengage the door
from the opening mechanism and require re-setting of the door.
Re-setting of the door can be done as follows:
a Manually close the door as far as possible
b Press and release the door button
c Move the door back and forth until it clicks
d Press and release the door button again
The door should now operate normally, otherwise repeat the
above process.

FAULT FINDING
The most likely causes of your lift failing to operate are:
• The door not being fully closed
• Something obstructing the travel of the car or infill panel safe
edge causing one or more of the sensors or safe edges (Figure
1) to operate and therefore preventing travel in the appropriate
direction.
To assist in identifying the cause the car is fitted with a simple
system of coloured indicator lights on the rear panel, one red, two
yellow and two green, (Figure 8).
