port and the PVC pipes, and use the snap ring for fastening.
2. Then connect PVC with solvent weld to complete the drainage.
3. To avoid water flowing back into the SBOX, ensure the drain has a
fall of 1/100 away from the SBOX.
4. While connecting drains, make sure the gravity drain doesn’t exceed
20m. If drain termination cannot be done within 20m, install an
external pump. Make sure the drain is supported every 800mm
(dependant on quality of drain pipe). Ensure no dips are in the drain.
5. Follow fig 5-2 for connecting multiple units on one drain.
6. The termination of the drain pipe should be terminated 50mm
above the ground. When installing make sure a dry trap or U bend
is installed. This will prevent smells and water returning back up the
drain.
CAUTION
Make sure every joint in the drain is sealed using solvent weld.
5.2. Drainage test
5.2.1 Before carrying out drainage test, make sure you have checked
to make sure there are no dips in the drain. Make sure all drain
have been sealed.
1. Use a water main to fill the water tank with 500~1000ml water.

6.4. The Procedure of Connecting Pipes
1) Connect the indoor unit first, and then connect the outdoor unit.
a. The pipe bend should be handled carefully, without damaging the pipe and
insulation layer. Ensure once you have installed the indoor unit, cover with
plastic to stop dirt and dust collecting inside the unit. Failure to do so will
cause damage to the unit.
b. Before tightening up the flare nut, apply refrigerant oil at the outer surface of
the pipe. Screw up the nut for 3~4 circles beforehand (see Fig.6-1).
c. Ensure when connecting and disconnecting pipe work, use two spanners
simultaneously.
d. Ensure that you don’t over tighten the flare nut. This will deform the
connection pipe on the indoor unit and cause leaks.
2) Ensure when making flare you tape/cover the inlet of the indoor unit, to
ensure no impurities go inside the unit.
3) After connecting all the pipe work, ensure you flush the system through with
nitrogen and pressure test according to outdoor installation manual.
i.The bend angle shall not exceed 90°. (See Fig.6-2)
ii. Where possible use long radius bends to help flow of refrigerant.
iii. Do not bend the pipe more than three times.
i. When bending the pipe, measure the pipe length required, mark bend
position and bend with benders.
ii. Longer radius elbows are recommended to help flow of refrigerant.
iii. Always use pipe benders when bending pipe.
2. Fixing pipe work
1) Ensure you use appropriate brackets for supporting pipe work.
2) Ensure the liquid pipe and the suction pipe feeding one unit are bound
together, with the correct cable.
3) When installing pipe work through walls, you need to protect pipe work with
large plastic pipe work.
