4 INSTALLATION
4.1Dimensions of the unit:
Select an installation site where the following conditions are satisfied and one that meets with your customer's approval.
- Safe places which can bear the unit's weight and where the unit can be installed at an even level.
- Places where there is no possibility of flammable gas or product leak.
- The equipment is not intended for use in a potentially explosive atmosphere.
- Places where servicing space can be well ensured.
- Places where the units' piping and wiring lengths come within the allowable ranges.
- Places where water leaking from the unit cannot cause damage to the location (e.g. in case of a blocked drain pipe).
- Do not install the unit in place s often used as a work space. Incase of construction work (e.g. grinding etc.) where a lot of
dust is created, the unit must be covered.
- Do not place any object or equipment on top of the unit (top plate)
-Do not climb, sit or stand on top of the unit.
- Be sure that sufficient precautions are taken in case of refrig erant leakage according to relevant local laws and regulations.
- Don’t install the unit near the sea or where there is corrosion gas.
When installing the unit in a place exposed to strong wind, pay special attention to the following.
In normal condition,refer to the figures below for installation of the unit:

At delivery, the unit must be checked and any damage must be reported immediately to the carrier claims agent.
Check if all indoor unit accessories are enclosed.
Bring the unit as close as possible to the final installation position in its original package in order to prevent damage during transport.
When the water tank is free of water, the maximum net weight of indoor unit with water tank shall reach about 158Kg，which needs
to be lifted by special equipment.

6 CONNECTING THE WATER PIPING
6.1 Connecting the space heating(cooling) water piping
To facilitate service and maintenance, two shut-off valves(field supply) and one overpressure bypass valve should be
installed. The two shut-off valves should be mounted on the space heating(cooling)water inlet and outlet .
Fig. -1
The shut-off valve should be mounted on the domestic cold water inlet.
1.Connect the shut-off valve to the cold water inlet .
2 Connect the cold water pipe to the shut-off valve.
3 Connect the domestic hot water pipe to the hot water outlet

The power of the unit also needs to be cut off after water in the system is drained.
The insulation material should at
least of B1 fire resistance rating and complies with all applicable legislation. The thickness of the sealing materials must be at least
13 mm with thermal conductivity 0.039 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 insulation
materials should be at least 20 mm in order to avoid condensation on the surface of the insulation piping.
which use the heat pump and backup heater (if aviliable) to protect the entire system from
freezing. When the temperature of the water flow in the system drops to a certain value, the unit will heat the water by using the heat
pump or the electric heating tap or the backup heater. The anti-freeze protection function will turn off only when the temperature
increases to a certain value.

Throat bander
Connect the drainage pipe with a throat bander and insert the drainage pipe into the floor drain.

The
flow switch should be removed and dried, then can be reinstalled in the unit.
NOTE
CAUTION
Be careful not to deform the unit’s piping by using excessive force when connecting the piping. Deforming the piping may
lead to malfunction of heat pump.
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 to prevent dust and dirt entering.
Use a good thread sealant for sealing the connections. The sealing must be able to withstand the pressures and temperatures
of the system.
When using non-copper metallic piping, be sure to insulate two kind of materials from each other to prevent galvanic corrosion.
As copper is a soft material, use appropriate tools for connecting the water circuit. Inappropriate tools will cause damage to the pipes.
NOTE
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:
Never use Zn-coated parts in the water circuit. Excessive corrosion of these parts may occur as copper piping is used in the
unit's internal water circuit.
When using a 3-way valve in the water circuit. Preferably choose a ball type 3-way valve to guarantee full separation between
the domestic hot water and floor heating water circuit.
When using a 3-way valve or a 2-way valve in the water circuit. The recommended maximum changeover time of the valve
should be less than 60 seconds.
1.Counterclockwise rotation, remove the flow switch.
2.Dry the flow switch completely.
