Outdoor Unit Drain Joint And Anchoring - Rinnai Pro Series Installation Manual

Outdoor unit - drain joint and anchoring
Installing the drain joint
Before bolting the outdoor unit in place, install the drain joint at the bottom of the unit. There are
two different types of drain joint depending on the outdoor model.
If the drain joint comes with a rubber seal
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 the water from the
unit during heating mode.
If the drain joint doesn't come with a rubber seal
1. Insert the drain joint into the hole in the base pan of the unit, it will click into place.
2. Connect a drain hose extension (not supplied) to the drain joint to redirect water from the unit
during heating mode.
In cold climates, make sure the drain hose is as vertical as possible to ensure quick water
drainage. If the water drains too slowly, it can freeze in the hose and flood the unit. Insulating the
drain hose in cold climates is recommended.
Anchoring the outdoor unit
The outdoor unit can be anchored to the ground or to a wall mounted bracket with bolts (M10).
Prepare the installation base of the unit according to the dimensions on the previous page.
To reduce the transmission of vibration and noise, a waffle pad or something similar shall be
installed beneath the unit at each anchor point.
