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 or in some cases 60°C where required.

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 remote controller will look like this: it will show Zone,

on SET 0.0°C and DHW set 48.0°C standard. The on off button will

be lit up in white. This is normal.

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

On the right of the controller it will say DHW set 48°C standard, this means your unit is monitoring the cylinder temperature.

The unit is set up to maintain the water between 43 and 50°C for efficiency, this can be increased to operate between 53 and 60°C all

the time if required.

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.

With if you want to heat the cylinder quickly press right so the DHW is high lit in blue press ok the screen will show the set temperature,

you can adjust this here. It should be on 48°C. Press ok and the screen offers options of economic, standard, power and forced, scroll

down 2 x to forced, press ok. This will heat the tank to set temperature immediately with the HP and Immersion together. It will return to

standard after 1 hour.

An anti-legionella / disinfection operation will be completed at a 3am every Tuesday 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 Samsung heat pump should be maintained at least once a year to comply with warranty and RHI.

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.

Maintenance of Monobloc Systems

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.

With if you want to test the cylinder quickly press right so the DHW is

high lit in blue press ok the screen will show the set temperature, you

can adjust this here. It should be on 48°C. Press ok and the screen offers

options of economic, standard, power and forced, scroll down 2 x to

forced, press ok. This will heat the tank to set temperature immediately

with the HP and Immersion together. It will return to standard after 1

hour. Measure the immersion heater current it should draw 12-13 Amps.

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.

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 12 and 16 - 1420mm (h) 940mm (w) 330mm (d) 103kg

Size 8 - 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-E03CN

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 329mm wide, 439mm high, 168mm deep, and weighs

3.5kg

The Samsung remote controller MUST be in a heated space above

5 degrees C.

You need to connect the hot and cold feeds, the tundish and drains. You need to install an expansion vessel on the heat pump side and

the heating side of the system and one onto the cylinder. The 300l cylinder needs a floor area of 700 wide by 850 deep, the cylinder is

1650 high and 555mm diameter. The 200l cylinder needs a floor area of 700 wide by 800 deep, the cylinder is 1500 high and 510mm

diameter.

Installation

When commissioning this system, you need to follow the procedure below don’t skip this, if you do the unit won’t work properly

Fill in the warranty card on page 4 and 5 Hand the end user pages 6-8.

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, on a Telford cylinder 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. If there are no lights you will need the electrician to check for power.

The remote controller will light up immediately, it will say scanning 0, after a few

seconds it will say scanning 1.

Scanning 0 means the indoor unit is ok, scanning 1 means the outdoor unit is ok. If

scanning 1 does not show after 30 seconds check the outdoor unit is powered up.

Remove the cover and check the PCB is lit up.

Setting up the controller and the time.

1. Press the gear button, bottom right. Press v, then > option,

press OK

Heating & Hot Water, Pre-Plumbed

Installation

Cylinder Timer, if you are heating a hot water cylinder

To avoid the cylinder heating being switched off accidentally we normally add 2 on timers a day, one

at 3-00 am and one at 15-00 pm. This stops nuisance tripping, resets the unit after power cuts and

insures the cylinder is hot 24 hours a day. We don’t normally set any off times.

To set the cylinder up as above:

1. From the front screen press the gear button, scroll right > to schedule, press ok.

2. If any timers are showing highlight them and select delete. When no timers are shown we can

add some new ones.

3. Highlight + add schedule, press ok

4. Highlight daily schedule, press ok

5. Type - quiet will show, press v to DHW, do not use quiet

6. Press > press ^ to set to Standard, press >, adjust hour to 3, am press ok

7. Scroll up ^ to + add a timer

8. Highlight + add schedule, press ok

9. Highlight daily schedule, press ok

10. Type quiet will show, press v to DHW, do not use quiet

11. Press > press ^ to set to Standard, press >, adjust hour to 3, pm press ok
