Place Remote System
Roof preparation
Most installations of this system will place the
condensing unit on the roof of a building. The roof
must be physically able to accept the load of the
equipment and the roofing material must be prepared
to prevent water leaks.
Follow local codes for the placement and attachment
of the equipment.
Location
The condensing unit requires unobstructed air flow
to operate efficiently. A four foot space between
each intake side and a wall or other cabinet is
recommended.
Do not place where it will pick up hot discharged air
from an air conditioner or other refrigeration system
condensing unit.
Space must also be reserved for service on the
condensing unit.
Roof Piercing:
The roof (or wall) must have an opening
large enough for the three refrigeration tubes
and the control wire to pass through. The
minimum recommended size is 4” ID. In
most areas the power supply may also pass
through the same passage. If there isn’t a
passage one must be created. In most cases
this must be done by a licensed and bonded
roofer in order to maintain the roof’s integrity.
Roof Pipe Curb or Pitch Pocket:
To avoid potential kinking of the refrigeration tubing,
avoid small, tight radius types of covers on pitch
pockets.
Suggestions:
In most cases a mechanical lift, boom truck or crane
will be required to hoist the condensing unit.
Mount unit to roof rails or curbs and secure with lag
screws or similar field supplied fasteners.
Orient the assembled unit so that the unit’s mounts
are parallel to the pitch of the roof to allow water to
drain freely.
Do NOT place the unit directly onto roof rock.
In all cases the line set will need to be
shortened to fit.
Do NOT leave excess line set exposed
outdoors, especially on a roof.
Refrigerant Recovery and System
Evacuation Notice
In the event the refrigerant must be
recovered from this system and the
system evacuated, recover and evacuate
from the three ball valve access valves.
