Thermal Insulation Work
 Insulation material must be able to withstand the
pipe heat
- Heat pump unit – heat resistance polyethylene foamed
(> 120°C)
- Cooling only unit – polyethylene (> 100°C)
 Insulation method
 Thickness of insulation

Gas Charge
Page 49
Gas Charge
Additional Refrigerant Charge
 The amount of additional charge must be
determined by the equation with the total length of
liquid pipe.
 After calculation, the amount of additional charge
should be recorded to the reverse side of the of the
outdoor unit control box cover.
 Put in liquid state refrigerant from the liquid port to
connect the cylinder by using weight scale.

Wiring Design
 All wires and accessories must be tested
beforehand
 All electric work must be done by licensed
electrician
 Wiring connection should be referred to the
installation manual
 Breaker and fuse should be set on each outdoor
unit
Page 56
Wiring
Communication Wires
 Twisted pair wired with shielding (20AWG)
- Shield wire to be earth on 1 end of the network
- Connected serially to the adjacent unit (Daisy Chain
Connection)
- Same polarity between units (A-A, B-B)
Wire Limitation (Units in meter)
• PC to Gateway – 2m (RS232)
• 1st Outdoor to Last Outdoor < 1000m (RS485)
• Outdoor to Last Indoor < 1000m (RS485)

Summary
 3 basic rules of refrigerant pipe work :
- Dry, Clean and air tight
 Both liquid and gas pipe should be insulate
separately
 The communication wires must be in the same
polarity
 DO NOT wrap the power cable and communication
wire together
