Outdoor Unit 
Installation
Step 2: Install drain joint (Heat pump unit 
only)
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.

IN COLD CLIMATES
In cold climates, make sure that the drain 
hose is as vertical as possible to ensure 
swift water drainage. If water drains too 
slowly, it can freeze in the hose and ood 
the unit.
Step 3: Anchor outdoor unit
The outdoor unit can be anchored to the 
ground or to a wall-mounted bracket with 
bolt (M10). Prepare the installation base of 
the unit according to the dimensions below.
