The attentive matters in installation of air suction and discharging duct
■ Recommend to use anti-frost and sound-absorbing duct. (locally bought)
■ The duct installation work should be nished before the tment of ceiling.
■ The duct must be heat insulated.
■ The specic air-discharging outlet should be installed at the place where
the airow can be reasonably distributed.
The examples of improper installation
■ Do not use air inlet duct and take the ceiling inner side as duct instead. The
result is because of the irregular outer air mass, strong wind and sunshine,
the humidity is increased.
■ There may be water drop on the outside of duct. For cement and other new
constructions, even if not taking ceiling inner side as duct, the humidity will
also be so high. At this time, use glass ber to perform heat preservation to
the whole. (use iron net to bind the glass ber) Maybe exceeding the unit
operation limit (for example: when indoor dry bulb temperature is 35 c, wet
bulb temperature 24 c), it may lead to overload of compressor.
■ Affected by the capacity of air discharging fan, the strong wind in the outer
duct and wind direction, when unit air sending volume exceeds the limit, the
discharged water of heat exchanger will overow, leading to water leakage.
The gas side pipe, liquid side pipe must be faithfully heat insulated, if no heat insulation, it may cause
water leakage.
■ The outdoor unit has been charged with refrigerant.
■ When connect the pipe to the unit or dismantling the pipe from the unit, please follow the gure shown, use
spanner and torque spanner together.
■ When connect cone nut, the inner side and outside of cone nut should paste with refrigerant oil. Use hand to twist
3-4 rings, then fasten with spanner.
■ Referring to Table I to conrm the fasten torque. Too tight may damage nut leading to leakage.
■ Check if the connection pipe leaks, then do heat insulation treatment, as below gure shown.
■ Only use seal cushion to bind the joint part of air pipe and heat insulation parts.
