(4) There should be water pipes, hot water interfaces, and floor drains to facilitate water
replenishment for the water tank, hot water supply, and drainage.
4 Refrigerant Pipe Design
4.1 Precautions on Pipe Design
The refrigerant pipe must meet the following requirements:
Material requirement: Dephophorization seamlessly drawn copper pipe for air conditioner
Appearance: Both inner and outer surfaces of the copper pipe should be free from pinhole, crack,
peeling, bubble, inclusion, copper powder, carbon accumulation layer, green rust, dirt, severe oxidation
film, and obvious defects such as scratch, pit and spot.
Inspection report: The certificate of quality and quality inspection report must be provided.
Specification: For standard configuration, one TP2M Φ9.52 (or Φ12) and one TP2M Φ6 are
configured for the unit. Length of both pipes is 3 m. If the pipe needs to be extended, this specification
needs to be followed.
The Sinclair air source water heater system poses high requirements on cleanliness and dryness.
Therefore, special attention must be paid when connecting the refrigerant pipe to the indoor and outdoor
units. If any impurity, moisture, or dust is left in the pipe due to improper operation, many problems may
occur to the system and the system may fail to work.
4.2 Pipe Installation Diagram
4.2.1 Installing the Refrigerant Pipe
(1) If the water tank and the outdoor unit need to be connected by punching through a wall, a hole of
Φ 55 mm must be drilled in the wall and the hole should be inclined toward the exterior wall, as shown in
Figure 4-1. Protective sleeves need to be put on both sides of the hole.
(2) Bind up the connecting pipes, power cord, water temperature sensing package, and
communication lines (if necessary) of the wired controller with thermal insulation bands, and then lead
them through the hole.
(3) Remove the refrigerant pipe joint from the water tank and the sealing nuts from the small and
large valves of the outdoor unit, and add refrigerant oil on the joint and valve cones.
