Refrigerant Pipe Installation - Samsung AM160FNBDEH Installation Manual

Refrigerant pipe installation

Refrigerant pipe work
Use exclusive tools and accessories for R-410A to respond to pressure of the R-410A and prevent foreign substances from
entering into the pipes.
The length of refrigerant pipe should be as short as possible and the height difference between the DVM Hydro unit /
Hydro unit HT and outdoor unit should be minimized.
Piping work must be done within allowable piping length, height difference, and the allowable length after branching.
The pressure of the R-410A is high. Use only certified refrigerant pipe and follow the installation method.
Use clean refrigerant pipe and there shouldn't be any harmful ion, oxide, dust, iron content or moisture inside pipe.
Pipe work must be done aside from the product.
After completing the pipe installation, calculate the additional amount of refrigerant according to method of each indoor
units and make sure to use R-410A refrigerant when charging. (Color of the R-410A refrigerant container is painted in
pink.)
Model name of DVM Hydro unit
Amount of additional refrigerant
Do not use Flux when welding the refrigerant pipes.
In case the capacity conjunction of the Hydro Unit HT exceeds 50 % among the total indoor unit, please don't
put the additional refrigerant.
CAUTION
When operate Hydro unit HT to add R-410A refrigerant at the outdoor unit side, Hydro unit HT will not work for
cooling refrigerant charging operation if water temperature is under 33°C. Peform heating refrigerant charging
operation or perform cooling refrigerant charging operation after warming water up over 33°C.
When operate Hydro unit HT to collect R-410A refrigerant at the outdoor unit side, Hydro unit Ht will not work if
water temperature is under 33°C. Perform refrigerant collecting operation after warming water up over 33°C.
All other indoor units should perform the heating or stop, when R-134a refrigerant collecting operation.
Important information regulation regarding the refrigerant used
DVM Hydro unit HT contains fluorinated greenhouse gases covered by the Kyoto Protocol.
Hermetically sealed system.
Do not vent gases into the atmosphere.
