Underfloor Heating
If you are looking for an underfloor design which we guarantee will have the heat pump at the centre of the system design,
instead of as an add on, come and talk to us at Freedom HP.
Pipe
We supply a high quality 16x2mm
multilayer pipe, consisting of 5 layers of
polyethylene, adhesive and aluminium.
Typically rated at 95°C at 10bar, this strong
flexible pipe is well suited to underfloor
heating, and is manufactured within the
EU.
Controls
At Freedom we provide a wide range of
controls manufactured by leading brands
such as Heatmiser, Danfoss and Reliance.
On offer are basic dial thermostats to
the latest digital phone app controlled
products.
Manifolds
Our brass manifolds are made in Germany,
and are supplied to us by Watts Industries.
This premium product has individual flow
meters, isolation ball valves, and is fitted
with an auto air vent and pressure gauge to
aid testing.
Plate Systems
Our plate system is generally used for a suspended floor. Insulation should be fixed
flush with the top of the existing joists to prevent downward heat loss. Battens are
fixed at 400mm centres at 90° to the existing joists. Aluminium trays are then laid and
stapled into position and the underfloor heating pipe is pressed into the grooves within
the trays.
The pipe warms the trays and the heat is spread across the floor. Chipboard or plywood
can then be laid and fixed to the battens.
Overlay Systems
Overlay panels provide many advantages over other insulation products when used
with warm water underfloor heating systems.
Our panel dimensions are 1250mm in length by 350mm in width and either 20mm or
25mm high.
Screed Systems
A Screed System is where the underfloor heating pipes are incorporated within the
solid floor structure. Staples, interlocking cliprail or castellation mats are fixed directly
on to the floor insulation. At Freedom Heat Pumps, we can provide everything from
staples to cliprail through to castellation mats in order to suit your project.
Quotations are provided without obligation, and a fully insured BS1264 compliant AutoCAD pipe layout can be prepared prior to delivery
and installation. This affords the client an opportunity to approve our suggestions prior to final acceptance.
Do you have a project which you would like us to provide a competitive underfloor heating quotation for?
If so, please email [email protected] or call 02380 274 833

Samsung Warranty Registration 7 Year
All Samsung heat pumps can now be registered for a 7-year parts warranty, covering only the Samsung components.
Any labour charges for replacing faulty parts are not covered. 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.
Your installer may offer you there own 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 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 . 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 and a maintenance book will be emailed to the applicant, please make sure you have a copy of
this certificate, and proof of maintenance. Samsung may ask for this when a warranty claim is made.

Handover of the System
Leave these 5 pages with the Homeowner. When you register the unit for warranty we will email you a manual that you can
leave with them on site.
Please search YouTube for Freedom Heat pumps Handover Video for Samsung Heat Pump for Homeowners
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.
By far the cheapest way to run a heat pump is to leave it on 24/7 at one set temperature, dont turn it off and dont time clock it. But if
you insist on switching it off . 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.

Handover of the System
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.

Handover of the System
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.

Maintenance of Monobloc Systems
The Samsung heat pump should be maintained at least once a year to comply with warranty and RHI. Please leave maintenance
records with the homeowner, they may need them if they have a warranty claim. See end user manual for details.
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.

Installation
Installing the Outdoor Unit (Boiler)
Position the outdoor unit so that the air flows into an open area, where there are no plants and animals. If the unit is to be installed within
a mile of the sea you need to have the unit coated suing Blygold, ask us for details. If you are applying for RHI and going through MCS you
need to make sure the system meets MIS020.
Install the outdoor unit on a flat, stable surface, it needs to be securely mounted at least 100mm off the ground on rubber feet. The unit
must be bolted down for security using 10mm bolts and Zebedee’s.
The unit must have adequate drainage away from the unit; it can produce up to 6 L / hour of condensate. If you are installing the unit at
height you can install a drain pan under the unit but its best to let the unit drain into the ground.
Dimensions:
Size 16 - 1420mm (h) 940mm (w) 330mm (d) 103kg
Size 9 - 998mm (h) 940mm (w) 330mm (d) 75kg
Size 5 - 798mm (h) 880mm (w) 310mm (d) 59kg
The space around the unit is very important, allow:
300mm to the left hand side (facing the front of the unit),
600mm to the right of the unit,
300mm to the rear of the unit and 1500mm to the front of the
unit.
Installing the Control Box MIM-03AN
The control box contains the flow switch, cylinder sensor (blue) 2
red safety sensors, some cables for a backup heater, a black cable
for smart grid connections and the remote controller.
Install the control unit indoors, it’s not waterproof.
It needs to be sited within 15m of the hot water cylinder, less than
100m from the outdoor unit and as near as possible to the pump,
flow switch and any zone valves.
The box is 323mm wide, 339mm high, 131mm deep.
The Samsung remote controller MUST be in a heated space above
5 degrees C.

Heating & Hot Water, Pre-Plumbed Installation
When commissioning this system, you will find its already been completely set up for you, but here are a few things you need to do.
Fill in the warranty card on page 5 and 6
Hand the end user pages 7-11.
Start-up Procedure
Filling and flushing, when installing any Heat pump, we insist on a thorough system flush prior to connection in line with the Building
Regulations for England and Wales, Part L, 2006. Using the power flusher fill the system with water and 25% Propylene Glycol, there is no
pressure sensor in the unit so we can operate from open vented to 3 bar maximum.
Setting up the cylinder immersion heater
To avoid the immersion heater cutting out before the legionella function is complete
you have to set the stat in the immersion heater to 70°C minimum, set it to 5.
Check the tank sensor
The blue tank sensor MUST be installed above the immersion heater and it must be
securely fixed in the tank right into the back of the pocket, I would use heat paste and
cable ties to do this.
Powering Up
Makes sure all your room thermostats are off and all underfloor run signals are off.
Apply power to outdoor and indoor unit, you should see red lights on the PCBs of both units check this If there are no lights you will need
the electrician to check for power.
The remote controller will be dead for about 4 minutes; after that it will come to life. You will see 00 first then 01 on the remote controller
screen for 90 seconds. If 00 continues to show the outdoor unit is not powered up or its not connected. Get the sparky to check this.

Heating & Hot Water, Pre-Plumbed Installation
Electrically testing the unit
The unit has a function to test all the wiring without any tools, this is really useful to check everything has been set up correctly. Test
each component one at a time to check its ok.
Operation Button Display
Enter test mode – hold the left and right buttons together for 4
seconds
Run the water circulation pump (Terminal B8 live) – Press the red
Heating on/off button leave this running
You should check flow rates here see below
Run the immersion heater (Terminal A3&A4) – press the Mode
button (Heating)
Open Valve HW for hot water (Terminal B17 live) – press the
Outing Button
Heating valve 1 is normally open (B10 live), to close valve for
heating Zone 1 – press the Set button
Turn up your room thermostats, when they come on heat will
show. This shows a run signal is received at the unit, turn stats
down again test will reappear
Operate Zone 1 thermostat
Checking flow rate
First you need to clean the filter balls.
Shut the valve, undo the back of the valve, remove the strainer, clean it and replace it then open the
valve.
Press right and left button together for 6 seconds. The controller will display TEST or 7E57 or HEAT,
press the power on/off button to start the pump. When the pump is running you can see a picture
of a house with a circle around it.
The unit will be running in heating mode. Check the flow rate, we need 12l/min on the 5kW unit, 20l/
min of flow on the 9kW unit and 30l/min on the 16kW unit. If there is not enough flow the unit will
never operate and it will give fault E911 see fault code page.
If you look into the flow meter you can see the flow in litres per minute. The flow rate is the low
figure, in this picture you can see a flow rate indicated, this shows 0l/min NOT 16l/min. Make sure
you clean the filter ball, turn up all the pumps, open all the valves and get rid of the air to keep flow
rate up.

Heating & Hot Water, Pre-Plumbed Installation
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. If the outdoor unit doesn’t start after 5-minutes, see problems
page.
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 again.
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.
Run test in hot water mode
Press View until a picture of a tap appears, this is the hot water cylinder temperature, note it down.
After 15 minutes of running check the hot water temperature again, it should have risen, again note the temperature. If the unit is
running well it should heat the cylinder to 48°C without needing the immersion heater. Now clean the filter ball again.
The Water storage temperature is lower (48°C) than a normal cylinder. It’s important to check that any shower or bath mixers do not
further reduce the water temperature. Using your thermometer check that the hot water comes out the tap at the same temperature
it leaves the cylinder. If it doesn’t you might need to make adjustments to taps mixers etc.. DON’T raise the cylinder temperature to
compensate.
Now handover the system to the end user, see page 7-11, fill in the warranty card on page 5 and online. Your system is now
fully commissioned, congratulations.
