REFRIGERANT PIPING WORK
5.
〈
For refrigerant piping of outdoor units, see the installation manual attached to the outdoor unit.
〉
〈
Execute heat insulation work completely on both sides of the gas piping and the liquid piping.
Otherwise, a water leakage can result sometimes.
〉
(When using a heat pump, the temperature of the gas piping can reach up to approximately 250°F, so use
insulation which is suffi ciently resistant.)
〈
Also, in cases where the temperature and humidity of the refrigerant piping sections might exceed
86ºF or RH80 %, reinforce the refrigerant insulation. (13/16” or thicker) Condensation may form on
the surface of the insulating material.
〉
〈
Before refrigerant piping work, check which type of refrigerant is used. Proper operation is not
possible if the types of refrigerant are not the same.
〉
DANGER
Refrigerant gas may produce toxic gas if it comes in contact with fi re such as from a fan, heater, stove or
•
cooking device. Exposure to this gas could result in severe injury or death.
