Auxiliary pipes
• Carefully arrange pipes so that any pipe does not stick out of the rear plate of the indoor unit.
• Carefully connect the auxiliary pipes and connecting pipes to each other and cut off the insulating tape wound
on the connecting pipe to avoid double-taping at the joint, then seal the joint with vinyl tape, etc.
• In order to reduce the possibility of condensed water being produced within the indoor unit, make sure to
insulate both the connecting pipes.
(Use a suitable form of insulation material specifically design designed for refrigeration pipe work.)
• When bending a pipe, ensure care is taken to prevent pipe damage.
