UNIT LOCATION

DANGER
Appliances must not be installed where they may be exposed to
potentiallyexplosiveorflammableatmosphere.
Handling
Each unit will be shipped to the site on a wood skid. Whenever
possible, all lifting and handling of the unit should be done with
the packing and skid in position.
When slinging or using a forklift to lift the unit, the support points
shouldbesufficientlyaparttogivestabilitywhenlifting.Unless
otherwise noted, the lifting points should be equidistant from the
centerline. Extreme care should be taken not to drop the unit.
Considerable damage can occur to the unit during positioning,
in particular, to the paneling and exterior paint. Use an adequate
number of personnel and the correct tools when moving the unit.
The unit is designed to remain upright so care should be taken
when lifting the unit up steps.
The use of torque screwdrivers on panel, cover or component
mounting screws is not recommended. Hand-start all screws.
If electric drills are used – set at the lowest possible torque.
Preparation
1. Before installation, ensure that the correct electrical power
supply is available for the unit.
2. Each unit requires an independently fused and isolated power
supply.
3. If the installation has multiple units, check that unit
identificationscorrespondwiththenetworkdiagrams.Advise
Modine immediately if discrepancies are noted.
4. Check to make sure that the units will have adequate
installation clearance around them.
5. Note that each unit has a condensate connection at the
rear and suitable provisions should be made for draining. If
multiple units tee into a common drain manifold, the drain
line must be sized to ensure free draining with all the units in
operation.
6. Inspect the wall sleeve installation for gaps that would allow
leakage of outdoor air into the space. All joints and abutments
should be sealed with waterproof sealant.
Drainage
Each unit has an internal condensate drain, terminating
internally to the unit. A 1-3/8" condensate drain hole is available
onthebacksideoftheunit(seeFigure9.1forthelocation).
This must be connected to the main drain system in accordance
with any local codes and general good piping practice.

Electrical wiring should be done in accordance with all
applicable national and local codes. It is the responsibility of the
electrical contractor to adhere to such codes. The warranty will

INSTALLATION

The instructions detailed below are for the Installation of a
"Standard" unit. Accommodations and adjustments will be
required for the usage of additional unit accessories. Should
assistance be required for the installation of these additional
items, consult Modine at the phone number listed on the back
cover of this manual.

2. After adjusting for any irregularity in the location site, locate
thepositionforthefloormountingbolts(seefigures8.1-11.1).
Drill the appropriate sized holes, for the fasteners that are to
be utilized, and insert the anchors that are to be used.
3. Remove the backing strip from the gasket on the wall sleeve.
Place the unit in the correct location, ensuring a tight seal with
the wall sleeve and the wall.
4. Check to ensure that the unit is plumb and level in both
directions. If adjustment is necessary, Modine recommends
the placement of metal shims in the outer most corners of the
base.
5. The cabinet must be secured to either the back wall or the
floor.Thefloorofthecabinethasfourpre-punchedholesand
