Concealed Duct High Static Pressure

Installation Manual

 

Refrigerant amount to be added

For addition of the refrigerant, add refrigerant “R410A” referring to the attached Installation Manual of outdoor unit. Be sure to use a scale to charge the refrigerant of specified amount.

REQUIREMENT

Charging an excessive or too little amount of refrigerant causes a trouble of the compressor.

Be sure to charge the refrigerant of specified amount.

A personnel who charged the refrigerant should write down the pipe length and the added refrigerant amount in the nameplate attached to the service panel of the outdoor unit. It is necessary to fix the compressor and refrigeration cycle malfunction.

Open the valve fully

Open the valve of the outdoor unit fully. A 4mm-hexagonal wrench is required for opening the valve.

For details, refer to the Installation Manual attached to the outdoor unit.

Gas leak check

Check with a leak detector or soap water whether gas leaks or not, from the pipe connecting section or cap of the valve.

REQUIREMENT

Use a leak detector manufactured exclusively for HFC refrigerant (R410A, R134a, etc.).

Heat insulation process

Apply heat insulation for the pipes separately at liquid side and gas side.

For the heat insulation to the pipes at gas side, be sure to use the material with heat-resisting temperature 120°C or higher. Using the attached heat insulation material, apply the heat insulation to the pipe connecting section of the indoor unit securely without gap.

REQUIREMENT

Apply the heat insulation to the pipe connecting section of the indoor unit securely up to the root without exposure of the pipe. (The pipe exposed to the outside causes water leak.)

Wrap heat insulator with its slits facing up (ceiling side).
