Safety precautions

English

PREPARATION

POWER SUPPLY LINE, FUSE OR CIRCUIT
BREAKER

• Always make sure that the power supply is compliant with

current safety standards. Always install the air to water heat
pump in compliance with current local safety standards.

• Always verify that a suitable grounding connection is

available.

• Verify that the voltage and frequency of the power supply

comply with the specifications and that the installed power
is sufficient to ensure the operation of any other domestic
appliance connected to the same electric lines.

• Always verify that the cut-off and protection switches are

suitably dimensioned.

• Verify that the air to water heat pump is connected to the

power supply in accordance with the instructions provided
in the wiring diagram included in the manual.

• Always verify that electric connections (cable entry, section

of leads, protections…) are compliant with the electric
specifications and with the instructions provided in the
wiring scheme. Always verify that all connections comply
with the standards applicable to the installation of air to
water heat pumps.

• Be sure not to perform power cable modification, extension

wiring, and multiple wire connection.

– It may cause electric shock or fire due to poor

connection, poor insulation, or current limit override.

– When extension wiring is required due to power line

damage, refer to "How to connect your extended power
cables" in the installation manual.

CAUTION

• Make sure that you earth the cables.

– Do not connect the earth wire to the gas pipe, water

pipe, lighting rod or telephone wire. If earthing is not
complete, electric shock or fire may occur.

• Install the circuit breaker.

– If the circuit breaker is not installed, electric shock or

fire may occur.

• Make sure that the condensed water dripping from the

drain hose runs out properly and safely.

• Install the power cable and communication cable of the

indoor and outdoor unit at least 1m away from the electric
appliance.

PREPARATION

Typical application examples

CAUTION

• The application examples given below are for illustration purposes only.

• When the SAMSUNG Air-to-Water Heat Pump system is used in series with another heat source (e.g. gas boiler), ensure that

the return water temperature not exceed 55°C.

• The unit is only to be used in a closed water system. Application in an open water circuit can lead to excessive corrosion of the
water piping.

• SAMSUNG can not be responsible put responsible for incorrect installations in the water system. Make sure that the boiler,
radiators, convectors, solar collectors, UFHs, FCUs, additional pumps, pipes, and controls in the water system are in accordance
with relevant local laws and regulations under the installer’s responsibility.

• SAMSUNG shall not be held liable for any damage resulting from not observing this rule.

• SAMSUNG do not provide specific water system components such as Pressure relief valve, Air vent valve, buffer tank and etc.
Installers and end-users shall consider how to install the above designated components in overall water system depending on
the installation conditions. If the components are not installed in appropriate location, the water system can not be operated
as designed.

Flushing and air-purging

When filling water, the following start-up procedure should be followed.

1 All system components and pipes must be tested for the presence of leaks.
2 Preparation of a make-up water assembly or Flushing unit is recommended for installation and service.
3 3. Before connecting pipes to the hydro unit, Flush water pipes clean to remove contaminants during 1 hours using a flushing

unit or tap water pressure if it is adequate (at 2 to 3 bar)

4 Fill water into the hydro unit by opening service valves.
5 Purge the air. (Fill with a flushing unit with sufficient capacity: avoid aerating the water)
6 Circulate for long enough to ensure that all air has been bled from the complete water piping system.

After installations, Commissioning should be performed by qualified representatives.

Unless flushing and air-purging works are performed adequately, it might result in malfunctions.

If the pressure loss of total system is over 43(9kW) or 20(16kW)kPa, additional water pump should be installed in series.

Otherwise, the flow rate might decreased, causing insufficient heating or cooling.

When ESP is not enough, additional pump should be installed. In this case, install the PWM control external type pump (Heating

Setting the pre-pressure of the expansion vessel

When it is required to change the default pre-pressure of the expansion vessel(1 bar), keep in mind the following guidelines:

• Use only dry nitrogen to set the expansion vessel pre-pressure.

• Inappropriate setting of the expansion vessel pre-pressure will lead to malfunction of the system. Therefore, the pre-pressure
should only be adjusted by a licensed installer.

Cap

After installation is completed the following procedures shall
be used to charge water into the hydro unit.

• Connect water lines to water connections of hydro unit.

• The air-vent valve shall be opened at least 2 turns and

drain valves shall be closed.

• Open the service valve in the water supply connection.

• Water pressure of supply line shall be over 2.0 bar for good

charging work.

• Stop water supply when the pressure gauge of hydro unit

indicates 2.0 bar.

CAUTION

• Service space should be secured.

• Water pipe and connections must be cleaned using water.

• If internal water pump capacity is not enough, install

external water pump.

• Do not connect electric wire while water charging.

• When initial installation or re-installation required, open

the cap to prevent air trap in the unit while charging water.

• The back-up heater vessel shall be full of water before

heater is turned on. Confirm if the vessel is empty by
opening the pressure relief valve of hydro unit. (OK if water
is flowing out)

• It is recommended to install the make-up water

assembly to feed small quantities of water to the system
automatically, replacing the minor water losses and
maintaining the system pressure. This assembly usually
consists of a pressure-reducing valve, water filter, check-

valve and shut-off valves. In this case, Check-valve must be
installed to prevent from contaminating city water.

Pressure relief valve

A pressure relief valve is integrated on heater vessel of hydro
unit and shall work in abnormal condition for protecting the
hydro unit.

CAUTION

• The pressure relief valve will operate releasing the

pressure by flowing out some water through the drain
hose.

• Make certain that the discharged water out of drain pan

can not contact any electrical parts.

Piping insulation

The complete water circuit, including all piping must be
insulated to prevent condensation forming on the surface of
the pipe and heat loss to external environment.

Wiring work

CAUTION

• Field-supplied electrical components such as power switch, circuit breakers, wires, terminal blocks, etc must be properly
chosen with compliance with national legislation or regulation.

• Switch off the power supply before making any connections.

• All field wiring and components must be installed by a licensed electrician.

• Use a dedicated power supply.

• All power connections must be protected from dew condensation by thermal insulation.

• The system shall be earthed. Do not earth the unit to a utility pipe, surge absorber or telephone earth. Incomplete earth may
cause electrical problems.
