Foundation for Installation
• Fix the unit tightly with bolts as shown below so that the unit will not fall down due to earthquake.
• 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 200 mm (7-7/8 inch)).

General Considerations
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.
• Never connect electric power while proceeding water charging.
Water Piping and Water Circuit Connection
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.
• 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 tefron 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 valve(e.g. 3way valve or 2way valve) should be less than 90 seconds.
• Pipe is insulated to prevent heat loss to external environment.
Strainer
- Use the 30 mesh strainer. (Exclude scale diameter of 0.8 mm or less and other net)
- Check the strainer direction and assemble on the inlet hole (Refer to picture)
- Wrap the Teflon tape on the screw thread of the water pipe for more than 15 times for assembly.
- Install the service port facing downward. (Within left/right 45 degrees)
- Check if there is any leakage on the connecting part.
- Clean the strainer periodically. (Once a year or more frequent)

Water cycle minimum requirements
1. For selecting the components of the hydraulic system, be sure they are above the design water
pressure.
2. For the water pipe, diffusely tight water pipes are recommended instead of steel pipes.
3. For the drain pipe size, use the same diameter as the product connected or larger. Always install a
natural drainage so that the drained water does not flows back
4. Install insulated material across the total hydraulic piping to prevent condensation and to prevent
low cooling or heating capacity during heat transfer losses. If the temperature is higher than 30 °C
and the humidity is higher than 80 % the insulation material must be minimum 20 mm thick to
prevent condensation.
5. Install the shut-off valve (1) to block the water by closing the valve when replacing the component
or cleaning.
6. Install an expansion tank (2) based on the water volume of the hydraulic system.
7. Install the drain valve (3) that can be used for draining the water inside when replacing the
component or providing service.
8. Install a magnetic dirt separator (4) at the inlet water pipe If the air separator is not installed there
can be formed air bubbles inside the hydraulic system. Flow error will be showed first on remote
controller, however finally a plate heat exchanger may burst during combined circumstances.
9. Install a circulation pump (5) which meets the water flow specifications mentioned inside product
data book.
10. Install the strainer (6) at the inlet water pipe connection to protect the PHE. Do not charge water
into the water pipe directly during Hydro Kit operation. If the strainer is not installed, component
malfunction of Hydro Kit may occur.
- For the strainer, use one with 30 mesh or above with measurement diameter of 0.8 mm or less.
- Always install the strainer on the horizontal pipe.
11. Install a balancing valve (with flow meter) (8)
12. Install an automatic air separator in the outlet water pipe (9)
13. Install pressure safety relief valve (10) in vertical upright position that meets the design water
pressure to prevent unit or water pipe damage during pressure increase inside the water pipe
system.
14. Install a pressure meter (11) in the outlet water pipe.
15. Install in case of cascade hydraulic systems or bivalent systems a flow-check valve (12) at each
outlet water pipe.
16. Install a buffer tank (13) of at least 10L/kW heating capacity in order to have a correct defrost
cycle, if there is no knowledge about the type and dimensions of the heating system. If there is
no buffer tank installed, the product can be damaged during normal operation or defrost
operation.
17. After product operation for 2 weeks in case of new installation, clean the water filter. In the
beginning of operation small particular dirt from installing process can block the filter which can
lead to damage of the product.
