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.

Protection for the field piping. The anti-freeze valve must be installed (field supply)
· Vertically to allow water to flow out properly and free from obstructions.
· At the lowest point in all field piping.
· In the coldest part and away from heat sources.
Water isolation inside the house in case of a power outage.
Normally closed valves (located indoors near the inlet/outlet pipes) can prevent all water in the indoor plumbing from draining when the anti-freeze valve is opened. (filed supply)
· Power outage: The normally closed valves close to shut off the water in the house. When the antifreeze valve is open, only water outside the house is drained.
· Other situations (eg pump failure): When the antifreeze valves open when the power is still applied to the normally closed valves, the system will drain completely.

16 English

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).

Piping length (m) < 20
20 ~ 30 30 ~ 40 40 ~ 50

Minimum insulation thickness (mm) 19 32 40 50

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:

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.
