    Indoor unit Installation Indoor unit Installation • Select a location where air can be distributed to all corners of the room. • Make sure no obstruction to return and dischage air. • Avoid installation at the following location: - area where flamable gas may leak or generated. - places where unit is frequently exposed to corrosive gas, or acidic solutions.
  • Page 14 Condensing unit Installation Condensing unit Installation • In order to optimize capacity, unit shall be installed as recommended requirements :- a) Allow sufficient space around the unit, to avoid the recirculation of the hot discharge air. b) Ensure no obstruction air flow into or out of the unit. c) The location which is well ventilated d) A place which protected from direct sunlighght, use an awning for protection , if necessary.
  • Page 15 Condensing unit Installation Condensing unit Installation Unit Lifting Holes at the unit base are for the lifting purpose. Belt shall be used for lifting the unit, properly tied the belt to the holes , use shackles to tighten the belt. Make sure the belt strenght is able to withstand the unit weight.
  • Page 16: Refrigerant Piping Connection

    Unit Installation Unit Installation Field Copper Tubing Connection To ensure satisfactory operation and performance, the following points should be noted for the field tubing arrangements of the complete refrigerant cycle. a) Liquid loops or oil traps must be provided according to the position of the outdoor and the indoor units (depending on whether the indoor unit is above or below the outdoor unit).
  • Page 17 Unit Installation Unit Installation Charging Hose Most field-charging is done using standard service hoses. Hoses are made in different colors with different working pressures and with different leak rates but the most important point is the presence or absence of hoses This slows evacuation and vapor charging dramatically.
  • Page 18 Unit Installation Unit Installation Charging Hose Refrigerant R410A : special precaution ii) Check List Before Installation / Servicing • Tubing -Refrigerant R410A is more easily affected by dust or moisture compared with R22, make sure to temporarily cover the ends of the tubing prior to installation •...
