Outdoor unit drain work
General area
While the air to water heat pump is operating in heating mode, ice can
accumulate on the surface of the condenser. To prevent ice from growing, the
system occasionally enters a defrost mode and the ice on the surface thaws
off. Water dripping from the condenser is guided through the drain holes to
prevent ice formation inside the base plate at subzero temperatures.
· In case there is not enough space for natural drainage from the outdoor
unit, additional drain work is required. Follow the description as per below:
Provide a minimum of 150 mm of free space to the floor. Insert the drain
plug into the hole at the bottom of the outdoor unit. Connect the drain hose
to the drain plug. Make sure dirt and debris cannot block the drain (hose).
Clean the base plate whenever needed. For the remaining holes (that do not
have the drain plug), insert the drain cap Make sure that the water dripping
from the drain hose runs away correctly and safely.
WARNING
· If the drainage is not adequate, it can lead to stagnant water and ice
build-up, causing system performance issues and possible damages.

About the piping work
Water connections must be made in accordance with the Water Piping and Wiring
diagram delivered with the unit, respecting the water inlet and outlet. If
air, moisture or dust gets in the water circuit, problems may occur.
Therefore, always take into account the following when connecting the water
circuit: · Use clean pipes only. · Hold the pipe end downwards when removing
burrs. · Cover the pipe end when inserting it through a wall so that no
dust and dirt enter. · Use a good thread sealant for the sealing of the
connections. · The sealing must be able to withstand the pressures and
temperatures of the system. When using non-brass metallic piping, make sure to
insulate both materials from each other to prevent galvanic corrosion. ·
Because brass is a soft material, use appropriate tooling for connecting the
water circuit. Inappropriate tooling will cause damage to the pipes.
CAUTION
· Be careful not to deform the unit piping by using excessive force when
connecting the piping. Deformation of the piping can cause the unit to
malfunction.
· Always use two wrenches (spanners) for tightening or loosening the water
connections, and tighten connections with a torque wrench as specified in the
below table. If not, connections and parts can be damaged and leak.
· The unit is only to be used in a closed water system. If applications are in
open water circuit, it will generate heat exchangers fouling, corrosion, and
leak.

Protection of the water circuit freezing
To prevent the hydraulic components from freezing, it has a freezing
protection function that includes activation of the pump at low temperatures.
However, in case of a power failure, these functions cannot guarantee
protection. To protect the water circuit from freezing, any one of the
following acts shall be performed. · Add glycol to water. Glycol lowers the
freezing point of water. · Install the anti-freeze valve. The anti-freeze
valve discharges
water from the system before it freezes.
Freeze protection by glycol
Freeze protection solutions must use propylene glycol with a toxicity rating
of Class 1 as listed in Clinical Toxicology of Commercial Products, 5th
Edition.
WARNING
· Ethylene glycol is toxic and must not be used in the primary water circuit
in case of any cross-contamination of the portable circuit.
· If you add glycol to the water, do NOT install anti-freeze valve, to avoid
Glycol leaking out of the anti-freeze valves into the environment.
· If an anti-freeze protection is used, it will result in increased pressure
drop and it may also cause a slight capacity reduction.
CAUTION
· Due to the presence of glycol, corrosion of the system is possible.
Uninhibited glycol will turn acidic under the influence of oxygen. The acidic
uninhibited glycol attacks metal surfaces and forms galvanic corrosion cells
that cause severe damage to the system.
· A glycol with corrosion inhibitors is selected to counteract acids formed by
the oxidation of glycols.
· No automotive glycol is used because their corrosion inhibitors have a
limited lifetime and contain silicates which can foul or plug the system.
· Galvanized pipes are NOT used in glycol systems since the presence may lead
to the precipitation of certain components in the glycol’s corrosion
inhibitor.

Freezing protection: Anti-freeze valves
In order to prevent system water from freezing inside the pipework during
subzero ambient conditions after a sudden power outage, antifreeze valves are
advised if glycol is not a suitable solution. An anti-freeze valve opens when
the medium (water) is below a certain low temperature value. When using the
EHS for cooling in the summertime, an anti-freeze valve with ambient sensor is
required to avoid unwanted opening due to low water temperatures. To protect
the field piping against freezing, install the following parts:

CAUTION
· If the system is utilized for both cooling operations (summer), please
install anti-freeze valves with an ambient air sensor in order to avoid valve
opening due to low water temperatures. Alternatively set FSV #1012 (minimum
cooling set point) to 7 °C or higher in order to prevent triggering the anti-
freeze valves during cooling operation.

Outdoor water piping insulation
The complete water circuit, inclusive all the piping, must be insulated to
prevent condensation during cooling operation and reduction of the heating and
cooling capacity as well as prevention of freezing of the outside water piping
during winter time. The thickness of the sealing materials must be at least 9
mm with =0.035 W/mK in order to prevent freezing on the outside water piping.
If the temperature is higher than 30°C and the humidity is higher than RH 80%,
then the thickness of the sealing materials should be at least 20 mm in order
to avoid condensation on the surface of the sealing.
For piping in free air, it is recommended to use the insulation thickness as
shown in the below table as a minimum (with =0.035 W/mK).

Minimum active water volume
The minimum active water volume of the system is the amount of water which is
always pumped around, even when all valves in the system are closed. The use
of a buffer tank can increase the active volume and therefore the operation
time between compressor start and stop. Ideally, systems should be designed
for around 12 to 15 minutes of operation, in order to meet with our declared
efficiencies. This time frame is based on a maximum of 4 On/Off cycles per
hour. The required minimum active water volume can be calculated via the below
stated formula:
V= min

a) Samsung EHS ClimateHub Mono is available in 1-phase and 3-phase version.
b) Mixing valve temperature sensor for floor heating comes with tank
integrated hydro unit (15 m red cable, blue connector on PBA).
c) When both zones are simultaneously Thermo On, the operation is performed
based on Zone 2. Set the zone with the higher set temperature to Zone 2.
d) Air vent included in tank integrated hydro unit. In case that the water
piping would be located in a higher position than the air vent of the tank
integrated hydro unit, it is necessary to add additional one at the highest
position of the water circuit.
e) Pumps for radiator and floor heating can be regulated (on/off) by tank
integrated hydro unit (terminals B10/B11 and B14/B15) or their own regulators.
Based on the current logic only with two zones control with wired remote
controller. Not with thermostat.
f) 200 L tank integrated hydro unit has six connection pipes (water
inlet/outlet, space heating inlet/outlet and DHW inlet/outlet) while 260 L
model has additional pipe for DHW circulation.
g) The 4-pipe structure buffer tank shown in this scheme is an example of the
installation, and the buffer tank installation in the actual site can differ
depending on the project requirements.
