* This drain lift up mechanism must be installed inside an indoor unit. * Installing this drain lift up mechanism limits to arrange the refrigerant pipe only upward. * To facilitate installation of the drain lift up mechanism, it should be installed before indoor unit. * The size of the plumbing that must connect, by the refrigerant kind of the indoor unit

that corresponds in the case of PAC-SH85DM-E, changes.

5 Drain Piping

*For details on piping, refer to the installation manual of the indoor unit.

1.Apply vinyl chloride type abhesive to the drainage outlet of the drain lift up mechanism ① , then insert the VP-20 pipe ④ into it, (30mm deep)

2.Connect the VP20 pipe ④ and existing drain pipe using a 90-degree elbow etc. and adhesive.

3.Cover the VP-20 pipe ④ with the pipe cover ⑤.

4.Apply vinyl chloride type adhesive to the drain lift up mechanism ① and drain connecting hole on the indoor unit, then insert the flexible hose ⑥ into them. Take care that the hose does not twist.

*Insulate all pipes, from the drain lift up mechanism up to the outside.

CAUTION

Make sure that the refrigerant pipes are insulated in order to prevent condensation. Incomplete insulation may cause condensation on the surface wetting of the ceiling, floor and other important properties.

Make sure that the drainage pipes are carried out correctly following this manual and that it is insulated in order to prevent condensetion. Any dificiency caused by piping may result in water leakage, wetting of the ceiling, floor and other personal properties.

*Refer to the installation manual of the indoor unit together with this manual. *Perform the work after checking that the power supply is off.

1.Remove the beam.

2.Remove the electric parts cover.

3.Pull the electric parts box downwards.

4.Connect the lead wire of drain lift up mechanism to the CNP and CN4F connectors provided on the control PCB of the indoor unit.

5.Tie up the lead wires with the fastener 7 so that the wires do not come apart inside the electric parts box.

6.When the wiring is finished, re-install the electric parts box, its cover and the beam.

4 Refrigerant Piping

*For details on piping, refer to the installation manual of the indoor unit. [With the stop valve of the outdoor unit fully closed]

1.Apply lubricant to the flare sheet of the L-shaped pipes (gas pipe, liquid pipe)

2.Remove the flare nut and cap from the indoor unit.

3.Apply lubricant to the flare sheet connecting section of the indoor unit.

4.Connect the L-shaped pipes (gas pipe, liquid pipes) 8 and 9 quickly.

5.Fit the removed flare nut to the existing pipes and carry out flaring.

6.Connect the L-shaped pipes with the existing pipes in the same way.

7.Cover each connection with heat insulator

[After the refrigerant circuit is complete]

8.Vacuumize the refrigerant lines through the service port of the liquid stop valve.

9.Fully open the stop valves (both liquid and gas). * The method for oparating the stop valve is described on the outdoor unit installation manual.

*Through this test run, check that drainage is discharged properly and that there is no water leakage from any of the connections.

7 Test Run

1. Supplying water Supply approximately 1000cc of water to the air outlet.

*Refer to the installation manual of the indoor unit together with this manual.

[Make sure to follow the following points during drain piping.]

*Drain lifting height must be less than 600mm. *Incline the drain pipe downwards (1/100 or more) to the drainage side (outdoor). *Do not create traps or peaks. *Keep the horizontal piping within 20m. Use fixtures to prevent the pipe from waving. *Do not install air vent pipes. The drainage may spout out. *Use general-purpose hard vinyl chloride pipes (outer diameter:[26) and apply vinyl chloride type adhesive to prevent any leakage. *

Cover with insulator (made of foamed polyethylene, with specific gravity of 0.03 thickness of 9mm or more). *Do not install odor trap at the drain outlet. *Locate the end of pipe at a point where odor is unlikely to occur. *Do not insert the pipe directly into a drainage ditch where sulfur gas may be produced. *Use VP-30 pipes for centralized piping. Install the centralized drain pipe approximately 10cm below the output of pipes connected from the drain lift up mechanism.
