Leak Detection; Heat Insulation - Sinclair ASDH-96AI Service Manual

3.4 Install the connecting pipe of outdoor
Check whether the height drop between the indoor unit and outdoor unit, the length of refrigerant pipe, and the
number of the bends meet the following requirements:
The indoor and outdoor connecting pipe interface and power line outlet
Various piping and patterns can be selected, such as out from the front, the back, the side, and undersurface,
etc. (The follow display the locations of several piping and wiring knock-off interfaces)
Front out pipe

3.5 Leak Detection

Use soap water or leak detector to check every joint whether leak or not.
Notes:
A is low pressure side stop valve
B is high pressure side stop valve
C and D is connecting pipes interface of indoor and outdoor units

3.6 Heat Insulation

Do the heat insulation to the pipes of air side and liquid side separately. The temperature of the pipes of air
side and liquid side when cooling, for avoiding condensation please do the heat insulation fully.
 The air side pipe should use closed cell foamed insulation material, which the fire-retardant is B1 grade
and the heat resistance over 120°C.
 When the external diameter of copper pipe≤Φ12.7mm, the thickness of the insulating layer at least more
than 15mm;
 When the external diameter of copper pipe≥Φ15.9mm, the thickness of the insulating layer at least more
than 20mm.
 Please use attached heat-insulating materials do the heat insulation without clearance for the connecting
parts of the indoor unit pipes.
