- The clearance between the units must be sufficient to
ensure that the discharge air from one unit does not mix
with the supply air of another unit.

- If the air enters through the units on one side only and is
discharged through the top, the clearances can be reduced.

- The air enters through three sides and is discharged
through the top.

Installation on the ground
- 38XTZ units can be positioned on the floor of a patio, on
the ground or on a lawn. If installed on the ground or on
the lawn they should be mounted on a 100 mm high
concrete base that is 100 mm larger than the base unit on
all four sides.

- If this type of installation is used, ensure that the units are
not affected by flooding, snow accumulation or leaves.
- Ensure that the units are secured to prevent injuries to
people handling or working on the units.
IMPORTANT: Rainwater is drained through the unit base.
For this reason the units must be elevated above the concrete
base to allow correct drainage.
- Rainwater drainage
38XTZ units incorporate drillholes in the base in order to
correctly drain any condensate or rainwater which may
enter the unit in the fan area. Ensure correct drainage.
