properly grounded through
the receptacle to avoid
electric shock.The
grounding wire shouldn't
be connected with gas pipe,
water pipe, lightning
arrester or telephone line.
Please use
specialized
accessories or parts
to carry out
installation,or water
leakage, electric
shock,fire hazard may
resulted.
R410A refrigerant can
produce poisonous gas
once it meets fire, so please
ventilate the room
immediately if refrigerant
leaks out during installation.
Diameter of power
cord must be large
enough. Damaged
power cord and
connecting wire must
be replaced by
specialized electric
cable.

the end of PVC pipe into the drainage hole and then tighten it with drainage hole and wire
binder. Never connect the drainage hole and drainage hose with glue.
(5) When the drainage pipelines are used for several units, the position of pipeline should be
about 100mm(4 inch) lower than the drainage port of each unit. In this case, thicker pipes
should be applied.
Fig 4.3.1
4.3.2 Installation of Drainage pipe
(1) Drainage pipe should have the same diameter or larger diameter than the connection
pipes(PVC pipe, outside diameter 25mm, thickness≥1.5mm).
(2) Keep drainage pipe short and sloping downwards at a gradient of at least 1% for
preventing forming air bubbles.
(3) If the gradient of drainage pipe could not meet the installation requirements, raising pipe
should be applied.
(4) Insert the drainage hose into drain socket and then tighten the metal clamp securely.
(5) Warp the sealing pad over drainage hose and metal clamp for heat insulation.
(6 ) Make sure to perform insulation work for all drainage hoses in the room in order to
prevent any possible water dropping due to dew condensation.
(7) Apply the suitable diameter for converging drainage pipe according to the operating
capacity of the unit, as show in Fig. 4.3.2.
