Electrical Wiring - Hitachi RAS-5FSN Installation And Operation Manual

2. Calculation of Total Additional Charge Amount (W kg)
Put weight W1 and weight W2 calculated in items 1.1
and 1.2 into the following formula.
Total Q'ty of Additional Charge W = W1 + W2
-
Charging Work
Charge refrigerant (R410A) into the system according
to the instructions described in the "Installation
Manual".
-
Record of Additional Charge
Record the refrigerant charging quantity in order to
facilitate maintenance and servicing activities.
Total refrigerant charge of this system is calculated in
the following formula.

16. ELECTRICAL WIRING

16.1. GENERAL CHECK
1. Ensure that the field-supplied electrical components
(mains power switches, circuit breakers, wires,
connectors and wire terminals) have been properly
selected according to the electrical data indicated. Make
sure that they comply with national and regional
electrical codes.
2 Following the Council Directive 89/336/EEC and its
amendments 92/31/EEC and 93/68/EEC, relating to
electromagnetic compatibility, next table indicates
maximum permissible system impedance Z
interface point of the user's supply, in accordance with
EN61000-3-11

3. Check to ensure that the power supply voltage is within
+/-10% of the rated voltage.
4. Check to ensure that power supply has an impedance
low enough to warranty not reduce the starting voltage
more than 85% of the rated voltage.
5. Check to ensure that the ground wire is connected.
6. Connect a fuse of specified capacity.
WARNING:
Check to ensure that screws for terminal block are
tightly tightened.

Check to ensure that the indoor fan and the outdoor
fan have stopped before electrical wiring work or
periodical check is performed.
Protect the wires, drain pipe, electrical parts, from
rats or other small animals. If not protected, rats may
damage unprotected parts, and at the worst, a fire will
occur.
