Hire Shops
A mobile unit for halls, large offices
and similarly sized areas.
Operating & Safety Guide 950
With the indoor unit switched OFF and isolated
from its power supply, make all the connections
from the umbilical assembly.
All that remains is to plug the indoor unit into its
power supply and switch the supply ON.
Check that the amber power supply ON lamp is
illuminated, then press the red fan ON/OFF button
to start the indoor unit’s fan. The outdoor units’ fan
will start to operate ONLY when cooling is selected. Use
the fan speed control dial to select the indoor unit
fan speed.
If chilled air is required, press the green ‘cooling’
ON/OFF button and turn the thermostat control
clockwise to maximum.
The unit is fitted with a time delay device that will
prevent the compressor from starting for
approximately 4 minutes
The unit will now be running, allow a minimum of
10 minutes for it to begin cooling.
Once the desired room temperature has been
reached, gradually turn the thermostat control
anti-clockwise until you hear a ‘click’. The unit will now
only emit chilled air when the room temperature rises.
Finally, adjust the outlet grill fins at the front of
the machine to direct the airflow as required.
If the red fault lamp illuminates, switch the unit
OFF and isolate it from its power supply, then
contact your local HSS Hire Shop for advice.
Never use the Split Unit Air Conditioner except for
its intended purpose, If it will not do what you want,
assume you have the wrong equipment for the job.
Contact your local HSS Hire Shop for advice.
Only use the Split Unit Air Conditioner for the
purpose it was designed for. Improper use may cause
expensive damage and could be dangerous.
EQUIPMENT CARE
BASIC TECHNIQUES
Keep the equipment clean. You will find it less of a
chore if you clean it regularly, rather than wait until the
end of the hire period.
When not in use, store the equipment somewhere
clean, dry and safe from thieves.
Switch the unit OFF and unplug from its power
supply,
Remove all umbilical assembly connections from
both the indoor unit and the outdoor unit.
Finally, neatly coil the umbilical assembly and the
indoor unit’s power supply cable, ready for return
to your local HSS Hire Shop.

This equipment should be used by an able bodied,
competent adult who has read and understood these
instructions. Anyone with either a temporary or permanent
disability, should seek expert advice before using it.
Never use this equipment if you are ill,
feeling tired, or under the influence of
alcohol or drugs.
Never place anything on top of the indoor or
outdoor units and never obstruct their air vents.
Leave a 300mm gap all round to let air circulate.
Always switch OFF and unplug the equipment
when not in use.
Never carry or pull the equipment by its power
supply cable or umbilical assembly.
Check the condition of the equipment before use,
paying special attention to the condition of the
umbilical assembly. If it shows signs of damage, leakage
or excessive wear, return it to your local HSS Hire Shop.
Always transport, store and operate this
equipment in an upright position. If either unit has
been laid on its side, DO NOT SWITCH IT ON,
contact your local HSS Hire Shop for advice.
The HSS Split Unit Air Conditioner plugs into a
standard 230V 13amp power socket.
If the equipment fails, or if its power supply cable
or plug gets damaged, return it. Never try to repair
it yourself.
Keep flexes out of harm’s way, and clear of moving parts.
Extension leads should be fully unwound and
loosely coiled, away from the equipment. Never run
them through water, over sharp edges or where they
could trip someone.
Using electrical equipment in very damp or wet
conditions can be dangerous.
To reduce the risk of electric shock, always use
a suitable RCD (Residual Current-Operated Device)
available from your local HSS Hire Shop, or power the Split
Unit Air Conditioner from a power circuit with a built-in RCD.
Ensure the Split Unit Air Conditioner and power
socket are switched OFF before plugging into the
power supply.
Never operate the unit in very cold conditions it
works properly only at temperatures above 18ºC. If
the temperature in the room is above 35ºC, open all the
doors/windows and operate the fan only, to circulate the
air and help reduce the temperature.
GETTING STARTED
ELECTRICAL SAFETY
GENERAL SAFETY
Set the indoor unit up on a firm, level surface,
capable of bearing its weight and where motor noise
will not be a nuisance. Do not site the unit close to any
surface sensitive to heat, cold or moisture. Once in
position, lock the brakes on the swivel castors.
When setting up or restarting, allow both units to
stand/settle for 15 minutes before switching ON.
The outdoor unit can be situated up to a maximum
of 35m away from the indoor unit, dependent on
the number of additional lengths of umbilical attached.
However, do not exceed the maximum rise (or fall)
of 4.6m.
The umbilical assembly contains 4 main
connections, a power supply lead, a condensation
tube and two water pipes.
The connection is the same for both the indoor and
outdoor unit except that the connectors are
male/female and set in such a way that the umbilical
assembly can only be used in one direction.
The electrical lead has a male fitting on one end
and a female fitting on the other. The male should
be attached to the indoor unit (see illustration) and
the female fitting to the outdoor unit.
The water pipes are fitted with a simple quick
release coupling. To attach the water pipes, pull
back the coupling’s outer sleeve, push the male into the
female fitting, then let the sleeve snap back into place
(see illustration).
To disconnect the water pipes, simply reverse the
fitting instruction. It is possible for a drop of water to
escape when carrying out this procedure.
The clear condensation tube attaches to the
respective unit by simply pushing the tube into the
inline connector.
Attach the umbilical assembly to the outside unit
prior to positioning.
Site the outdoor unit in a convenient position
outside the room to be cooled.
The unit can be positioned through a suitable window
with the unit hung by chains, (available for hire from your
local HSS Hire Shop) or on a flat roof, but which ever method
is chosen the unit must be made secure.
The outdoor unit must be kept upright with the
fan motor assembly facing towards the building,
this way the hot air is directed away from the building.
