Freedom Heat Pumps Warranty Information
Who are Freedom Heat Pumps?
Freedom Heat Pumps are a wholesale distribution company for the Samsung EHS and the Hitachi Yutaki range of heat pumps and
underfloor heating systems. We offer technical support, training, design and consultancy services and operate the
www.samsungehs.co.uk and www.freedomhp.co.uk web sites and freedom heat pumps and Samsung EHS Facebook pages.
We launched Samsung’s eco heating systems in the UK in 2010 and have been market leaders in this sector with over 5500 units out in
the field. In 2016 we started distributing Hitachi’s Yutaki range of units to expand our heat pump portfolio and market influence.
We now also have our underfloor heating business and have expanded our heat pump ranges from both Hitachi and Samsung into the
commercial sector offering systems with capacities of up to 250 kW.
What we do
Our role is to provide design, and after care support to the installing plumbers and heating engineers working on the heat pumps we
supply. We also support engineers on site if they need help.
YouTube support
We run a YouTube channel for installers and home owners search for freedom heat pumps in you tube and you will find us.
What to do if you need help
If you have trouble with your system, your first port of call should always be the engineers who sold you your system or the maintenance
company looking after it. If you don’t have a maintenance agreement we can advise who the best people are to supply this in your area
just give us a call on 02380 274833 or email us at [e-mail] and we can set you on the correct course.
Please note if your unit is not maintained regularly this will affect your Samsung parts warranty.
All Samsung heat pumps can now be registered for a 7-year parts warranty covering only the Samsung components, The Samsung
warranty covers parts only. Any labour charges for replacing faulty parts are not covered. Your installer may offer you a full parts labour
and call out warranty as part of their maintenance agreement but you need to discuss this with the installer / maintenance company.
The Samsung warranty does not cover, radiators, cylinders, UFH, valves, pumps etc. It is the role of the installer to offer a warranty to the
end user covering the heating system including the heat pump.
The warranty will be held by the end user at the address the unit is installed. It is important that a qualified engineer services the unit
annually to maintain the warranty and register each maintenance online. It does not have to be the installer who does this, we can
recommend engineers to do this if the installer does not want to do this work.
Your unit is not automatically registered for warranty, your installer needs to fill in a form online at www.freedomhp.co.uk . Once this is
done a certificate will be emailed to the applicant, make sure you have a copy of this certificate, you may need it later.
At the back of this book are 7 years worth of maintenance records, make sure your engineer fills this in each year at service time, again
you may need this in event of a warranty claim

Thank you for buying a Samsung EHS heat pump system, your Samsung heat pump heats the house and hot water cylinder
much like a normal fossil fuel boiler, however there are a couple of differences which you should take notice of.
Your installer should have provided you with a room thermostat if you have radiators or a thermostat in every room if you have under
floor heating. The installer will be able to run through the operation of your stats with you. The heat pump will operate from the signal
sent by these stats back to the heat pump, please do not use the Samsung controller to control your heating.
Once the unit starts up it will take time to get to temperature, it is not instant. Within 10 minutes you should feel the radiators beginning
to warm up. Although it may take a few days to have everything to the required temperature, please do not switch your stats off during
this period.
Weather compensation and water law
The radiator temperatures will be lower than you are used to with a gas or oil boiler. To add to this, we run them in a weather
compensation mode, this means that the unit measures the outside temperature and adjusts the radiator temperature to suit.
The colder it is outside the warmer the rads will be and vice versa. This function is automatic and is designed to save you money. In very
cold weather the radiator will be at their hottest, they will reach 50°C.
Running your machine efficiently
It is very expensive to heat the house up from cold, with a heat pump the best advice is to maintain the house at as close to constant
temperature as possible all the time.
Please DON’T set the room temperature too low when you leave the house, ideally drop it no more than 2 degrees below your normal set
temperature when you go out or it will take a long time and a lot of money to recover.
To switch off the heating in summer set your room thermostats down to 16°C to avoid the heating starting up. Your radiators will have
thermostatic valves on them, you can adjust each room’s temperature with these.

General Advice
The heat pump comes with a Samsung controller which looks like
this, you should not use this or press the buttons, it is used for
commissioning and fault diagnosing the system only.
On Youtube (search for freedom heat pumps) there are videos
showing how to use the controller, faults etc.
Normally the controller will show AU or 0.0c on the left and a tap
in the right hand top corner. This is normal, it means the system
is controlled by external thermostats. If it says 0.0c you can boost
your heating water temp using + or – but it costs more money if its
set above 0.0C
If the system goes into fault, the screen will show a number at the
bottom starting with E, for example E911 – A00. The green light
will go out and a red light will flash. The engineer will want to know
this number when you call.
Please avoid turning the unit off at the power supply especially
in cold weather. If the unit is off and the weather is very cold, it
cannot protect itself and your warranty will be at risk.
If the unit is off and the temperature outside is cold, it will
automatically run the pump for a few minutes to stop freezing.
In extreme weather, below -2°C the water pump will run
continuously, you cannot stop this.
Hot Water
At the top right of the controller you should see a tap with 2 dots, this means your unit is monitoring the cylinder temperature.
The unit it set up to maintain the water between 43 and 50°C all the time.
As you use the water the heat pump will constantly top up the cylinder. The hot water cylinder has priority over the heating, if the
cylinder temperature falls 5 degrees below its set point the unit will automatically switch to heating the cylinder. This should take less
than an hour.
Once set temperature is achieved the unit will go back to heating the house. The hot water cylinder loses almost no heat (1/3 a degree
an hour) if no hot water is used.
If you want to heat the cylinder very quickly you can press the DHW mode button, on the right until a bath shows, this will run the heat
pump and the immersion together. Please remember to return the tap with two dots when it is no longer required.
An anti-legionella / disinfection operation will be completed at a 3am every Wednesday morning.
The unit will heat the cylinder with the immersion to 60°C, the hot water will be hotter on a
Wednesday morning than the rest of the week. If legionella is not completed this e919 will flash on
screen, you need to call an engineer to check it.
If you don’t require 24/7 hot water It is possible to time clock the hot water to reduce costs, the timer video on you tube will show you
how to do this.

Hot Water Mode:
Overview of the Samsung Controller
The outing mode button sets the hot water cylinder temperature to 25°C but has no effect on heating, this is
ideal for when you go away on holiday etc. If you turn all thermostats down as well the heat pump won’t run
which will save money.
The Silent mode button is not used, due to risk of freezing up etc.

Starting the unit in heating mode
Press the power button (top left) AU or 0.0C will show, the unit is automatic mode using an external
run signal. Turn up your thermostats or underfloor heating to send a run signal to the unit, the pump
will start within 3 minutes, a little house with a circle around it appears in the status window, the
compressor in the outdoor unit starts after 3 minutes, you will see the symbol for the compressor in
the status screen. It’s a little milk churn with a C in it. The pipework will begin to heat up.
Check the flow temperature by pressing oval View button, it will show 4 sensors. The house is the
temperature at the remote controller which is not used. The house with the circle around it is the
water outlet temperature from the heat pump. The Christmas tree is the air temperature outside. The
tap is the cylinder temperature.
Over time the unit will warm up, now check all the radiators or under floor loops are hot as well.
Starting the System in hot water mode
Clean the filter balls.
Press DHW on/off (power) button to start the unit, top right button.
A picture of a tap appears with dots by it, press Mode until 2 dots appear. This means the HP will heat
the water with help from the immersion.
Set the cylinder temperature press the oval Set button then press + until 48°C shows. The heat
pump will start heating the cylinder if its colder than 43°C and will heat it up to 50°C then it will stop.
The unit will take up to 6 minutes to start in Hot water mode, be patient
When the unit is heating the cylinder, this coke can symbol shows on the controller. The HW valve will
open but the heating valve will not close for 40 seconds, this is normal.
Please search YouTube for Freedom Heat Pumps for detailed videos on how to operate your Samsung EHS heat pump
Operation of your Samsung EHS Heat Pump
Energy Usage and Running Costs
Your Samsung EHS heat pump will use more energy during the winter
months when the ambient air temperature is cooler. Don’t be alarmed if
you see these winter months accounting for a large percentage of your
annual heating bill, as illustrated in the chart to the right, the system will
use much less energy during the warmer seasons.
You should make a note of your running costs each month from the
electricity meter, they are around the same size as a circuit breaker and
look like the below image.
Month % Energy used / month
January 19%
February 17%
March 12%
April 7%
May 4%
June 2%
July 1%
August 1%
September 4%
October 6%
November 12%
December 15%
Date Time Electric Meter 1 (kWh) Electric Meter 2 (kWh) Electric Meter for the
whole house (kWh)
Each month, make a note of the date, time, each electric meter reading, and the reading of electric meter for the whole house.
You may also wish to take a photo of the house meter.

Maintenance of Monobloc Systems
The Samsung heat pump should be maintained at least once a year to comply with warranty and RHI.
You should expect your maintenance engineer to complete the following procedures and record commissioning data with every annual
maintenance.
You must log your maintenance at www.freedomhp.co.uk for the 7-year warranty.
Maintenance procedure
Stop the unit, clean the water filters, shut the valve, undo the back
and pull the strainer out and replace it.
Test the concentration of the Anti-freeze (glycol) in the system
using a Glycol tester the level should be 25%. If you don’t have a
glycol tester a glycol tester / refractometer can be bought from
your heat pump supplier or online.
Refill the unit, pressure should be 0-3 bar.
We need to test the operation of the unit against the hot water cylinder. So first we need to draw off 50 litres of water, run a couple of
taps for 5 mins to achieve this. The unit should start up automatically in hot water mode, if it doesn’t press the DHW power button on
the controller, in 3-4 mins it will start heating the cylinder, a coke can symbol will show in the status section of the remote controller.
The heat pump should be able to achieve 48°C cylinder temperature without using the immersion heater.
While running, check the outdoor unit for damage & debris, the coil needs washing, we recommend you use an approved EHS heat
pump cleaning chemical, your distributor will stock this. Instructions are given on the bottle. You also need to clean and polish the
outside casing we recommend car wax to do this.
Hot Water Cylinder
Check electrical connections & sensor is above the immersion
and at least 100mm into the tank and the overheat thermostat is
set to 70°C. On a Telford cylinder set the stat to 5.
Press the mode button until a bath symbol shows on the Samsung
remote controller; this will force the immersion heater on. Check
immersion heater works properly, Measure the current drawn by
the heater; it should be 12-13 Amps.
Measure the temperature of the flow using the remote controller.
Measure the flow rate from the flow meter.
With the unit running flat out measure the temperature of the air as it enters the coil and the temperature of the air in the garden. They
should be the same check cold air is not recirculating.
