4.3 Install Outdoor Unit
Fix the outdoor unit with anchor bolts(M10)
Cation
Since the gravity center of the unit is not at its physical
center, so please be careful when lifting it with a sling.
Never hold the inlet of the outdoor unit to prevent it from
deforming.
Do not touch the fan with hands or other objects.
Do not lean it more than 45, and do not lay it sidelong.
Make concrete foundation according to the specifications
of the outdoor units.
Fasten the feet of this unit with bolts firmly to prevent it
from collapsing in case of earthquake or strong wind.
4.4 Install drain joint
Heat pump units require a drain joint. Before bolting the
outdoor unit in place, you must install the drain joint at the
bottom of the unit. Note that there are two different types
of drain joints depending on the type of outdoor unit.
• If the drain joint comes with a rubber seal (see
Fig. A ), do the following:
1. Fit the rubber seal on the end of the drain joint that will
connect to the outdoor unit.
2. Insert the drain joint into the hole in the base pan of the
unit.
3. Rotate the drain joint 90° until it clicks in place facing
the front of the unit.
4. Connect a drain hose extension (not included) to the
drain joint to redirect water from the unit during heating
mode.
• If the drain joint doesn’t come with a rubber seal
(see Fig. B ), do the following:
1. Insert the drain joint into the hole in the base pan of the
unit. The drain joint will click in place.
2. Connect a drain hose extension (not included) to the
drain joint to redirect water from the unit during heating
mode.
