The Outdoor Unit (boiler)
Position the outdoor unit so that the air flows into an open area, where there are no
plants and animals
Install the outdoor unit on a flat, stable surface, the unit 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 bolts.
The unit must have adequate drainage away from the unit; it can produce up to 6 L /
hour. 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.

What comes with the unit and what you will need:
Below is a list of the components which comes with fast connect,
Flexible hoses the water connections to the back of the
unit are 1 inch BSP male. We recommend connecting the
water pipework with flexible hoses for ease of maintenance
and to avoid any vibration from the unit going into the
house. All external pipework has to be insulated to meet
MCS standards.
Mounting feet, the outdoor units need to be mounted
100mm above the ground, we recommend using rubber feet with
unistrut channel. These come with mounting bolts included.
An expansion vessel, pressure gauge, pressure relief valve
and filling loop
In pressurised heating systems most heating engineers use a Robokit
which combines all these components into one box. The expansion
vessel is sized exactly the same way as when using a boiler. If you
want to run the system open vented you don’t need these components,
the Samsung units are happy to run at anywhere from 0 – 3Bar
pressure
Diverter valves
If you require multiple heating zones you need to supply a 2 port diverter
valves per zone.
Glycol / anti-freeze
In Monobloc heat pumps the water goes outside the building. The unit can protect
itself from freezing up, but if the power goes off there is a risk that the unit will freeze
causing damage. To prevent this, we recommend putting propylene glycol mixture in
the system. It is important that the glycol concentration is
adequate to protect the unit, if the unit freezes up there
will be no warranty. Manufacturer dependant, a mix of
25% is normal for UK conditions.
Adding too much glycol is not a good idea as it increases the water pump power and
slightly reduces the capacity of your system.
The Cylinder:
If you want to heat water with a heat pump you need a dedicated heat pump cylinder.
The cylinder needs to be installed less than 15m from the control box to allow for the
temperature sensor cable.
Cylinders can only be used IF the coil area is more than 2.5m^2. Smaller coils are
not acceptable and cannot be used. Please do not attempt to utilize a standard
central heating, non-heat pump optimized cylinder. Cylinders can be pressurised or
open vented.

Fast Connection kit page 1 of 4
The fast connection kit comes with all the accessories you need except a robokit and
Cylinder. The idea is the fast connect kit goes on the wall inside and is pre wired, and
commissioned. The plumber connects the cylinder, the heat pump and the heating
circuit.

Operation:
Hot water is controlled using the Samsung cylinder sensor and controller supplied.
This controller has inbuilt time clock control and includes both a daily and weekly
legionella sterilisation function.
The system can be either open vented or pressurised.
The cylinder must have a coil at least 2.5m^2
Cylinder size normally allows 55l of water per person per day.
We would recommend sizing the heat pump to recover the cylinder in 1 hour.
It is possible to connect this system to solar PV powered immersion heaters (I boost,
Immersun etc.)
Heating is controlled using a wall mounted thermostat / time clock (field supplied).
There are no limits to the number of heating zones which can be connected to this
system. This system shows 2 heating zones. (Pump 2 and Pump 3)
Each zone has its own thermostat / timer which drives a dedicated zone valve. The
zone valve will control the pump and send a run signal to the heat pump.
The system will run in a fully adjustable weather compensated mode adjusting the
water temperature to suit the ambient conditions.
We recommend a buffer; low loss header or heat exchanger is used to simplify the
installation.

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
The immersion heater has its own stat; this MUST be set to
70C. This is to avoid the immersion heater cutting out before
the legionella function is complete
Powering Up
Makes sure all your room thermostats are off and all underfloor run signals are
off.
Apply power to indoor control box first then the outdoor unit. Turn on all the breakers
in the fast connect.
The remote controller will be dead for about a minute, after that it will come to life.

Field Settings
Field settings define how the unit will work, each system will
have different field settings. Field settings are in groups, the
20s are for weather compensation and temperature control in
heating, the 30s are for the cylinder and the 40s are for
backup boilers and hybrid systems.
For example, if the field setting 4031 is changed to 1, it tells
the unit it is a hybrid
1. Enter field settings by pressing down and Set for 6 seconds, I do this with the
middle finger of both hands, it’s easier. 10 will show on the screen.
2. Press up once, 20 will be shown, press right, 2011 will show.
3. To adjust this setting press right once the value will appear at the left of the
screen, adjust it with the up and down buttons, to store this value press Set.
4. Press left to go back to 2011, press up to the next field setting and repeat.
5. When you have finished all your 20 settings press left twice, 20 will show on
the screen, press the up button to move to the 30s and repeat the procedure
from 2 above.
When finished or if you get lost press ESC to return to the normal screen
these settings will be already set in your unit

Electrically testing the unit:
It is possible to test each component
one after another using the service
function.
You can use this to make sure you have
wired everything correctly.
To access service mode press right
and left button together for 6 seconds.
The controller will display TEST or 7E57
press the power on/off button to start
the pump, we always run the pump
constantly in test mode.
When the pump is running you can see
a picture of a house with a circle round
it.
With all your stats off, the controller will display the word TEST. When you send any
run signal to the unit it will change to HEAT1.
Turn up a stat or the underfloor heating to test this. Now if you turn the stats and the
UFH off TEST will show again.
If you are doing a Hybrid system, you can test the operation of the boiler.
Press the Silent button, a milk churn with a B in it will appear, within 30 seconds the
boiler will run. Press Silent again to turn it off.
To exit service mode press ESC.

Checking flow rate before starting the heat pump.
The flow rate through the heat pump is very high and must never fall. An alarm will
show E911 if the flow falls below 17l/min on a 9 and 16Kw UNIT and 9l/min on a 5Kw
unit.
If you are using a header, buffer or heat exchanger this is easy to achieve. If
not …..
Testing the flow in heating mode
Press right and left button together for 6 seconds. The controller will display TEST
or 7E57, 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 round it
The unit will be running only in heating mode. Check the flow rate, IDEALLY 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.
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 25l/min
NOT 35l/min
If the flow rate is too low, you need to fix this before moving on. Turn up your
pumps, remove any air and if it’s still not enough you need bigger pumps. The
unit won’t work if the flow rate is too low.
Press esc to return to normal screen.
Flow Test: if you don’t have a header, heat exchanger or
buffer. Setting up the bypass valve
In heating mode (see above) close every TRV on every radiator and shut off all
underfloor heating loops. This is the worst case scenario for flow, the bypass valve
needs to be adjusted to make sure the flow rate is still above 16/l to avoid faults.
Adjust the bypass valve to achieve this. Now open the TRVs again and exit service
mode press ESC.

2016 b fast connect 14
Starting the unit in heating mode;
Press the power button (top left) AU will show meeting 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 immediately, a little house with a circle round 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.
The flow temperature is shown next to a symbol of a house in a circle. Over time this
will warm up, now check all the radiators or under floor loops are hot as well.
If the outdoor unit doesn’t start after 5 minutes……...
Caution in Cold weather
If the water in the system is below 10C the heat pump WILL NOT START.
Press the View button, you can see 4 sensor readings, press oval View until the
pump symbol shows (a circle round a house). This is the water temperature, if it’s
below 10C the unit will not start but the pump will run.
You must warm up the water to get the unit to run, the easiest way to do this is to run
the boiler.

Handover of the system. Leave this page with the
Homeowner
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.
To turn on the heating all you need to do is turn up the thermostat, to turn it off you
need to turn all the stats down. The thermostat sends a run signal to the heat pump.
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.
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 50C.
Once the temperature outside gets cold your heat pump will stop and it will fire the
boiler, this will make the radiators much hotter in cold weather.
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 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 the thermostats down to 16C 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.
Normally the controller will show AU or automatic mode, this means its looking for a
thermostat to tell it when to run.
If the system goes into fault, the screen will show a number at the bottom starting
with E, for example E911 – A00. Normally there is a sun symbol at the top of the
screen, if the unit is faulting the sun disappears. 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.
If the unit is off and the temperature outside is cold, it will automatically run the pump
for a few minutes to stop the unit freezing. In extreme weather, below -2C the water
pump will run continuously, you cannot stop this.
Hot Water
The hot water is supplied by your boiler just as it always was.

Warranty Registration Card
Warranty MUST be registered within 30 days of delivery to site. You must send proof
of delivery with the warranty card.
Warranty will start from the date the unit is delivered.
All registrations made more than 30 days after this period will be subject to a late
registration fee.
If commissioning data is not available at this time register the unit and send the data
at a later date, the warranty certificate will be returned to you when the whole form is
completed.
This warranty covers only the Samsung components of the installation, it is parts only
with a pre-set labour allowance only. The warranty is between Freedom Heat pumps
and the installation company only, this is NOT an end user warranty.
It is the role of the installer to offer a warranty to the end user covering all of the
heating system including the heat pump.
The standard warranty is valid for 12 months from date of delivery as entered on this
card. If the unit is installed by a Samsung approved installer and this card is sent
back within 30 days of delivery date the warranty is automatically extended to 36
months.
Approved installers also have access to warranty extensions at the time of
registration for warranty; a 4-year extension to the warranty can be purchased from
your distributor or directly from Freedom Heat Pumps.
Call 02380274833 for details and pricing
The warranty card can also be used as a maintenance card.
Please return a photo or scan of this form and the delivery note to

Maintenance Monobloc Systems
The Samsung heat pump should be maintained at least once a year to comply with
warranty and RHI. The warranty card also doubles up as a maintenance sheet.
Maintenance procedure
Stop the unit, clean the strainer or magnetic filter in accordance with manufacturer’s
recommendations 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 liters 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 48C 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.
