Field Wiring GENERAL CAUTIONS 1. Choose the correct AWG according to MCA values based on UL-1995. Follow technical standards for electrical equipment and wiring regulations. 2. When proceeding with the wiring and connections outside, avoid anything that could damage the power line and transmission cable, such as exposing to sunlight and rain.

CONTROL WIRING Use 2-Core stranded shielded communication wire. Wiring length limitations must be observed to avoid any communication interference. Table 29 —Wiring Length Limitation Max. length to Outdoor L1+L2,L5 ≤3937ft [1,200m] AWG 18 Max. total length to Indoor units L3, L3+L4 ≤3937ft [1,200m] AWG 18 Max.
REFRIGERANT PIPING DESIGN NOTE: For calculation purposes, assume equivalent pipe length of the branching pipe header to be 1.6 ft. (0.5m).

38VMA***RD system can extend the piping flexibly within its limitation to suit the actual situation. However, it will cause a decrease in cooling/heating capacity due to pressure loss because of the longer piping length. Use the following correction factor to calculate the capacity (approximately). Table 65 —Cooling Capacity Correction 38VMA072RDS5-1(RDS6-1) 38VMA096RDS5-1(RDS6-1) 38VMA120RDS5-1(RDS6-1) 38VMA144RDL5-1(RDL6-1)

Piping length needs to include the actual length and the equivalent length where the bends are counted. 38VMA072~336RDS(L)5-1 38VMA072~336RDS(L)6-1 Equivalent length = (Actual piping length to the farthest indoor unit) + (1.64 x number of bends on the piping) [ft.]...
