Sinclair SDV4 series - Piping Installation

54 Installation
While installing the outdoor unit, pay attention to the installation place and the drainage pattern; if it’s installed at the alpine
zone, the frozen condensed water will block up the water outlet, please pull out the rubber stopper of the reserve water
outlet. If that still fails to satisfy for the water draining, please knock open the other two water outlets, and keep the water
can drain in time. Pay attention to the knock the reserve water outlet from outside to inside, and it will be beyond repair
after knocking open, please pay attention to the installation place, lest cause the inconvenience. Please do the moth
proofing for the knocked out hole, to avoid the pest processing into and destroy the components.
4. Piping installation
4.1 Piping connection
Offering four directions to connect pipes and wirings for meet a variety of installation request.
Right side pipe connection: please remove the L-shape metal plate, otherwise cannot wiring.
Back side pipe connection: Please wipe off the piping support rubber blanket beside the inner outlet pipe cover of the
machine while back side getting out pipes.
Bottom side pipe connection: the knock out should from inside to outside, and then piping and wiring through this.
Pay attention to the piping the fat connecting pipe should out from the largest hole, otherwise the pipes will be rubbed.
Please do the moth proofing for the knocked out hole, to avoid the pest processing into and destroy the components.

Note: When the total equivalent piping length of liquid + gas side is ≥90m, it must increase the size of air side main pipe.
Besides, according to the distance of refrigerant pipe and the over matched state of indoor unit, when the capacity is
decreasing it still can increase the gas side main pipe size.
