INSTALLATION IN 38AKS014-024/INDOOR

FAN COIL (CONSTANT VOLUME)

SPLIT SYSTEM COMBINATION Step 1 — Install Piping (See Fig. 4)

Shut off all power to the unit and remove refrigerant charge using an approved refrigerant recovery device before pro- ceeding with installation. Failure to do so may result for personal injury.

IMPORTANT: Do not bury refrigerant piping underground.

1.In applications where the air handler refrigerant distribu- tor is not equipped with a side outlet connection, it is rec- ommended that a Sporlan in-line auxiliary side connector with standard distributor be used. Refer to the installation instructions for the indoor fan coil to obtain nozzle size and distributor connection size. Select the auxiliary side connector based on this information. The side connector must be installed on refrigerant circuit no. 1 (first stage of cooling) of the fan coil being used.

2.Install a field-supplied 1/4 in. NPT to 1/4 in. flare fitting on the gage connection port of the compressor suction service valve.

3.Sweat the pilot solenoid valve supplied in the hot gas ac- cessory package directly to the hot gas bypass valve on the 3/8 in. ODF external equalizer port.

4.Install field-supplied 1/4 in. copper tube (flared with a nut on each end) between the compressor suction valve and the hot gas pilot solenoid valve.

5.Connect a field-supplied 5/8 in. OD copper tube between the discharge line process tube (hot gas stub) and a field- supplied manual shutoff service valve, avoiding any traps in piping.

6.Connect another field-supplied 5/8 in. OD copper tube be- tween the manual shutoff valve outlet and the hot gas by- pass valve inlet.

7.Connect a field-supplied 5/8 in. OD copper tube between the leaving side of the hot gas bypass valve and the Sporlan auxiliary side connector (distributor-side connector).
