Installation Of Drain Pipe; Precautions For Lift Pipe - Ouellet CCD12KCHVS-I Owner's Manual

INSTALLATION OF DRAIN PIPE

• The diameter of the drain pipe should be larger than or equal
to that of the refrigerant pipe. (PVC pipe, outer diameter: 1 in.
(25 mm), wall thickness ≥ 1/16 in. (1.5 mm)).
• The drain pipe should be as short as possible and have a slope
of 1/100 degree minimum to avoid air pockets formation.
• If the installation do not allow proper drain pipe slope, a lift
pipe should be installed.
• A distance of 3.3 to 4.9 ft. (1 to 1.5 m) should be kept between
the hangers to avoid curves in the drain hose.
• Insert the drain hose into the drain hole and tighten it with
clamps.
• Wrap the clamps with a large amount of sponge for thermal
insulation.
• The drain hose inside the room should also be insulated.

PRECAUTIONS FOR LIFT PIPE

• The installation height of the lift pipe should be less than 11 in. (280 mm).
• The lift pipe should form a right angle with the unit, and distance to the unit should not exceed
11 13/16 in. (300 mm).

NOTES:
• The inclination height of the drain hose
should be within 3 in. (75 mm) so that
the outlet of the drain hose does not
suffer from external force.
