•
All wires must be firmly connected.
•
Make sure all the wire do not touch the refrigerant pipings, compressor or any moving parts.
•
The connecting wire between the indoor unit and the outdoor unit must be clamped by using provided cord anchorage.
•
The power supply cord must be equivalent to H07RN-F which is the minimum requirement.
•
Make sure no external pressure is applied to the terminal connectors and wires.
•
Make sure all the covers are properly fixed to avoid any gap.
•
Use round crimp-style terminal for connecting wires to the power supply terminal block. Connect the wires by matching
to the indication on terminal block. (Refer to the wiring diagram attached on the unit).
•
Used the correct screwdriver for terminal screws tightening. Unsuitable screwdrivers can damage the screw head.
•
Over tightening can damage the terminal screws.
•
Do not connect wire of different gauge to same terminal.
•
Keep wiring in an orderly manner. Prevent the wiring from obstructing other parts and the terminal box cover.
Connect wires of the
same gauge to both side.
1.
Set the parallel angle of the fan and the motor pulley as shown in Table 1 and Figure 1.
2.
Set the tension of one belt when the flexion load is within the range as shown in Figure 2 and Table 2 at the proper
flexion. (A=0.016xC mm)
3.
Adjust the suitable tension after the belt sit properly across the pulley (after working for 24-28 hours).
When a new belt is used, adjust the suitable tension about 1.3 times the maximum value of the flexion load.
4.
Readjust the belt every 2,000 hours after the first adjustment.
Exchange the belt when the belt's surroundings length has expanded by 2% including the first expansion (about 1%) of the
belt (after approximately 8,000 hours converted working time).
