• Seasonal wind and cautions in winter
  • Sufficient measures are required in a snow area or severe cold area in winter so that product can be operated well.
  • Get ready for seasonal wind or snow in winter even in other areas.
  • Install a suction and discharge duct not to let in snow or rain.
  • Install the outdoor unit in such a way that it should not come in contact with snow directly. If snow piles up and freezes on the air suction hole, the system may malfunction. If it is installed at snowy area, attach the hood to the system.
  • The raised support platform must be high enough to allow the unit to remain above possible snow drifts, and must be higher than the maximum anticipated snowfall for the location.
  • Where snow accumulated on the upper part of the Outdoor Unit by more than 10cm(3-15/16inch), always remove snow for operation.

1. Don't install the suction hole and discharge hole of the Outdoor Unit facing the seasonal wind.

Lifting Method

• When carrying the suspended, unit pass the ropes under the unit and use the two suspension points each at the front and rear.
• Always lift the unit with ropes attached at four points so that impact is not applied to the unit.
• Attach the ropes to the unit at an angle of 40° or less.

Be very careful while carrying the product.

• Do not have only one person carry product if it is more than 20 kg.
• PP bands are used to pack some products. Do not use them as a mean for transportation because they are dangerous.
• Do not touch heat exchanger fins with your bare hands. Otherwise you may get a cut in your hands.
• Tear plastic packaging bag and scrap it so that children cannot play with it. Otherwise plastic packaging bag may suffocate children to death.
• When carrying in Outdoor Unit, be sure to support it at four points. Carrying in and lifting with 3-point support may make Outdoor Unit unstable, resulting in a fall.
• Use 2 belts of at least 8 m long.
• Place extra cloth or boards in the locations where the casing comes in contact with the sling to prevent damage.
• Hoist the unit making sure it is being lifted at its center of gravity.

• The outdoor unit support block at the bottom shall have width of at least 100mm under the units legs before being fixed.
• The outdoor unit support block hold have minimum height of 200mm.
• Anchor bolts must be inserted at least 75mm.

The location of the Anchor bolts

Chassis	A (mm)	B (mm)	C (mm)
UXC	1,640	1,438	1,056

Foundation for Installation

• Fix the unit tightly with bolts as shown below so that unit will not fall down due to earthquake or gust.
• Use the H-beam support as a base support
• Noise and vibration may occur from the floor or wall since vibration is transferred through the installation part depending on installation status. Thus, use anti-vibration materials (cushion pad) fully (The base pad shall be more than 200mm)

• A : The corner part must be fixed firmly. Otherwise, the support for the installation may be bent.
• B : Get and use M10 Anchor bolt.
• C: Put Cushion Pad between the outdoor unit and ground support for the vibration protection in wide area.
• D: Space for pipes and wiring (Pipes and wrings for bottom side)
• E : H-beam support
• F: Concrete support

• Install where it can sufficiently support the weight of the outdoor unit.
  If the support strength is not enough, the outdoor unit may drop and hurt people.
• Install where the outdoor unit may not fall in strong wind or earthquake.
  If there is a fault in the supporting conditions, the outdoor unit may fall and hurt people.
• Please take extra cautions on the supporting strength of the ground, liquid outlet treatment(treatment of the liquid flowing out of the outdoor unit in operation), and the passages of the pipe and wiring, when making the ground support.
• Do not use tube or pipe for liquid outlet in the Base pan. Use drainage instead for liquid outlet. The tube or pipe may freeze and the liquid may not be drained.

• Be sure to remove the MDF(wood support) of the bottom side of the outdoor unit Base Pan before fixing the bolt. It may cause the unstable state of the outdoor settlement, and may cause freezing of the heat exchanger resulting in abnormal operations.
• Be sure to remove the MDF(wood support) of the bottom side of the outdoor unit before welding. Not removing MDF causes hazard of fire during welding.
  

Water Control

Water quality

Water quality should be complied with EN 98/83 EC Directives.

• If the product is installed at existing hydraulic water loop, it is important to clean hydraulic pipes to remove sludge and scale.
• Installing sludge strainer in the water loop is very important to prevent performance degrade.
• Chemical treatment to prevent rust should be performed by installer.
• It is strongly recommended to install an additional filter on the heating water circuit. Especially to remove metallic particles from the heating piping, it is advised to use a magnetic or cyclone filter, which can remove small particles. Small particles may damage the unit and will NOT be removed by the standard filter of the heat pump system.
• Water quality check should be implemented before completing the installation of system.

Detailed guide can be found in the table as below.

Frost protection

In areas of the country where entering water temperatures drop below 0°C, the water pipe must be protected by using an approved antifreeze solution. Consult your AWHP unit supplier for locally approved solutions in your area. Calculate the approximate volume of water in the system. And add six liters to this total volume to allow for the water contained in AWHP unit.

Antifreeze type	Antifreeze mixing ratio (by volume)
	0°C	-5°C	-10°C	-15°C	-20°C	-25°C
Methanol	0%	6%	12%	16%	24%	30%
Ethylene glycol	0%	12%	20%	30%	-	-
Propylene glycol	0%	17%	25%	33%	-	-

If you use frost protection function, change DIP switch setting and input the temperature condition in Installation mode of remote controller. Refer to 'CONFIGURATION > DIP Switch Setting > DIP Switch Information > Option Switch 3' and 'INSTALLER SETTING > Antifreezing Temperature'.

• Use only one of the above antifreeze.
• If a antifreeze is used, pressure drop and capability degradation of the system can be occurred.
• If one of antifreezes is used, corrosion can be occurred. So please add corrosion inhibitor.
• Please check the concentration of the antifreeze periodically to keep same concentration.
• When the antifreeze is used (for installation or operation), take care to ensure that antifreeze must not be touched.
• Ensure to respect all laws and norms of your country about antifreeze usage.

Water Piping System

Water piping and water circuit connection

Followings should be considered before beginning water circuit connection

• Service space should be secured.
• Water pipes and connections should be cleaned using water.
• Space for installing external water pump should be provided if internal water pump capacity is not enough for installation field.
• Never connect electric power while proceeding water charging.

1. Definition of terms are as follow:
   • Water piping: Installing pipes where water is flowing inside the pipe.
   • Water circuit connecting: Making connection between the unit and water pipes or between pipes and pipes.
2. While installing water pipes, followings should be considered:
   • While inserting or putting water pipes, close the end of the pipe with pipe cap to avoid dust entering.
   • When cutting or welding the pipe, always be careful that inner section of the pipe should not be defective. For example, no weldments or no burrs are found inside the pipe.
   • Drain piping should be provided in case of water discharge by the operation of the safety valve. This situation can be happened when the internal pressure is over 10 bar and water inside the unit will be discharged to drain hose.
3. While connecting water pipes, followings should be considered:
   • Pipe fittings (e.g. L-shape elbow, T-shape tee, diameter reducer, etc) should be tightened strongly to be free from water leakage.
   • Connected sections should be leakage-proof treatment by applying teflon tape, rubber bushing, sealant solution, etc.
   • Appropriate tools and tooling methods should be applied to prevent mechanical breakage of the connections.
   • Operation time of flow control valve(e.g. 3way valve or 2way valve) should be less than 90 seconds.
   • Drain hose should be connected with drain piping.

Water condensation on the floor

If underfloor cooling is performed, it is very important to keep leaving water temperature higher than 16 ℃. Otherwise, dew condensation can occur on the floor. If floor is in humid environment, do not set leaving water temperature below 18°C.

While cooling operation, condensed dew can drop down to the bottom of the unit. The condensing water must be sufficiently drained from the unit and dissipated frost-free.

Water condensation on the radiator

While cooling operation, cold water may not flow to the radiator. If cold water enters to the radiator, dew generation on the surface of the radiator can be occurred. Use 2way-valve to block circuits from cooling operation.
