ADDITIONAL INFORMATION ABOUT SAFETY
DO NOT CONNECT THE POWER SUPPLY TO THE UNIT
PRIOR TO FILLING THE SPACE HEATING CIRCUIT (AND
DHW CIRCUIT IF IT WERE THE CASE) WITH WATER
AND CHECKING WATER PRESSURE AND THE TOTAL
ABSENCE OF ANY WATER LEAKAGE.
Do not pour water into the unit. These products are equipped
with electrical parts. If the electrical components are in contact
with water, a serious electrical shock will take place.
Do not touch or adjust safety devices inside the unit. If these
devices are touched or adjusted, a serious accident can take

and when replacing parts.
It must be ensured that the heat pump cannot operate
accidentally without water neither with air inside hydraulic
system.
Check that the earth wire is securely connected. If the unit is

Do not connect the earth wire to gas piping, water piping,
lighting conductor or earth wire of a telephone.
of 0.1s or less). In the event of a fault, there is danger of an
poisonous gases into the refrigerant cycle when performing a
leakage test or an air-tightness test. These types of gases are
extremely dangerous and can cause an explosion.
Do not install the unit in the following places, otherwise, it may
-
Places where oil (including machinery oil) splashes.
-
-
Places where there is splashing water.

surface repels water. As a result, drain water splashes outside
of the drain pan and splashed water runs inside of electrical
box. In the end, water leakage or electrical devices failure may
occur.
