3.INSTALLATION STANDARD
3.1PRE-CHECK:
1.Remove the packing wooden base from indoor & outdoor unit.
2.Place the outdoor unit over mounting base (Concrete or I –beam) and place antivibration pad and mount as per installation instructions.
3.Positioned the Indoor unit over Top of condensing unit and bolted indoor with outdoor after fixing indoor to shelter cut-out portion.
4.Check there should not be any dents, dust in interconnecting piping.
5.Prepare inter connection pipe to connect indoor unit with outdoor unit as per following.
FLARED TYPE INTERCONNECTING PIPING |
SIZE X QTY. |
SUCTION LINE INTERCONNECTING PIPING |
1/2 inch X 2 |
LIQUID LINE INTER CONNECTING PIPING |
3/8 inch X 2 |
6.Wrap Teflon tape in direction of thread to the connectors & service valve before placing flared tubing.
7.Align the centre of the pipings (2 suctions & 2 liquids) and sufficiently tighten the flare nut with fingers.
8.Finally tighten the flare nut with torque wrench until the wrench clicks (40~80kgf). When tightening the flare nut with torque wrench, ensure the direction of tightening follows the arrow of wrench.

3.2. Levelling of Airconditioner
After placing the unit on Channel/concrete structure maintain the levelling of unit towards rear side with 10mm slope so as to ensure free flow drainage.
Water seepage problem may happen due to improper levelling of unit.
3.3. Shelter Cutout sealing
Angle flanges (4 nos) to be fixed with shelter wall after installation. These flanges are to be fixed with shelter wall after installation so as to prevent any leakage in shelter. after fixing the flanges; apply silicon sealant on edges of flanges to make complete leak free cut-out. These are not the part of unit accessories.
(B)
3.4. Condensate Drain pipe
1.Air conditioner is provided with one flexible drain pipe, which shall be connected to metal Drain pipe of unit & should be routed through gap between shelter wall and condensing unit (see fig. C).
2.Do Not leave drain pipe open, your airconditioner may suck condensate water and cause splitting of water inside the shelter.

3.5. Air purging of inter connection & Indoor unit
The air which contains moisture remaining in the refrigeration cycle may cause malfunction of compressor.
1.Confirm the both liquid valves& gas valves are set to closed position.
2.After connecting the piping, check the joints for gas leakage with gas leal detector.
3.Remove the service port nut, and connect the gauge manifold and vacuum pump to the service port by charge hose.
4.Vacuum the indoor unit & connecting pipes until the pressure in them lowers to below 76 cmHg.
5.Remove the valve stem nuts. and fully open the stems of service valves with hexagon wrench. & Tight the flare nuts of indoor & outdoor unit.
6.Purge the gas qty-80grams in each circuit to remove moist air contents.
7.Disconnect the charge hose and fit the nut to the service port. (Tightening torque:1.8kg.m)
3.6. Filter Cleaning
The Airconditioner is equipped with fine air filter (2 nos.). The Air filter are at front of unit shall be checked and cleaned every month or more often
if necessary.
