• Do not ground units to water pipes, telephone wires or lightning rods because incomplete grounding could cause a severe shock hazard resulting in severe injury or death, and to gas pipes because a gas leak could result in an explosion which could lead to severe injury or death. • Safely dispose of the packing materials. Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries.
• Be very careful about product transportation. Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dangerous. • Make sure to provide for adequate measures in order to prevent that the outside unit be used as a shelter by small animals. Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep the area around the unit clean.

• Use the following items for the refrigerant piping. Material: Jointless phosphor-deoxidized copper pipe Size: See “Example of connection” to determine the correct size. Thickness: Select a thickness for the refrigerant piping which complies with national and local laws. For R410A, the design pressure is 478 psi.
Example of connection 1: When 1 indoor unit is connected downstream from the BS unit Determine using Table 1 based Select from Table 2 depending on the total capacity of the indoor on the capacity type of the units connected downstream. indoor unit.
6-5 PIPING CONNECTION Follow the connection example below and connect the site piping. BSVQ36P type When the downstream indoor unit total capacity is 36 or less and when one indoor unit with a capacity of 24 to 36 is connected downstream.

8. INITIAL SETTING • When the refrigerant piping and wire installation work is completed, make the following settings as required. 1. Setting for when connecting the COOL/HEAT SELECTOR to the BS unit. 〈Setting description〉 Set the input signal from the COOL/HEAT SELECTOR (sold separately) to ON/OFF. 〈Setting method〉 Set the dip switches (DS1-1) on PCB (A1P) as shown at left before turning on the power to the BS unit. Turn on DS1-1.
