Water Quality
Water quality should comply with EN 98/83 EC Directives. Requirement for resolved chemical ingre-
dients is following table. Detailed water quality condition can be found in EN 98/83 EC Directives.
Frost protection
In areas of the country where entering water temperatures drop below 0℃(32℉), the water pipe must
be protected by using an approved antifreeze solution. Consult your
Hydro Kit
unit supplier for lo-
cally approved solutions in your area. Calculate the approximate volume of water in the system. (Ex-
cept the
Hydro Kit
unit.) And add antifreeze solution to the total volume to allow for the water
contained in
Hydro Kit
unit.

CAUTION
• If the unit 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.
CAUTION
1. Use only one of the above antifreeze.
2. If a antifreeze is used, pressure drop and capability degradation of the system can occur.
3. If one of antifreezes is used, corrosion can occur. So please add corrosion inhibitor.
4. Please check the concentration of the antifreeze periodically to keep same concentration.
5. When the antifreeze is used (for installation or operation), take care to ensure that antifreeze
must not be touched.
6. Ensure to respect all laws and norms of your country about Anti-freeze usage.
7. When hydro kit is applied for heating, the antifreeze never added in the water circuit.
