2.0 INSTALLATION
2.1 Receiving
the
Equipment
Your Mini-Space EC unit was inspected and tested for defects
before shipment. To ensure the unit is in excellent condition
when you receive it, visually inspect it upon delivery. Carefully
remove the shipping container and all protective packaging.
Open the access panels/doors and thoroughly inspect the
unit interior for any signs of transit-incurred damage. If there
is shipping damage, it must be noted on the freight carrier’s
delivery forms before signing for the unit. STULZ ships all
systems FOB factory. Any freight claims must be done
through the freight carrier. STULZ can assist in the claim
fi ling process with the freight carrier. Should any damage be
present, notify the STULZ Product Support Group before
attempting any repairs. Refer to section on page 30 for
instructions.
A “data package” has been sent with your unit. It contains
this manual; an
E²
controller manual and, optionally, other
component manuals; system drawings; applicable SDS’s;
a unit startup checklist; a warranty registration form; and
other applicable instructions based on the confi guration
and options of your unit. The data package has been placed
in your unit in a clear plastic envelope. Its documents should
be retained with the unit for future reference.
NOTE
Items that have been shipped loose, such as
controllers, temperature sensors, water detectors,
etc., are shipped inside the air conditioner unless
specified otherwise by the customer. The duct
connection plate or plenum box (if applicable) are
placed on top of the air conditioner inside the unit’s
carton. Remove and store these items in a safe place
unless you are using them immediately.
2.2 Site
Preparation
Mini-Space EC systems are designed for easy service access.
A component access door is located on the front of the
equipment. To maintain full service access through the front
hinged access door, no permanent obstructions should be
placed within 36 inches of the front of the unit. (See Figure 2).
NOTE
Working clearance requirements need to be
established prior to mounting the unit. Refer to local
and national electrical codes.
To minimize the effects of the environment surrounding
the conditioned space, certain steps must be taken. This
is especially true for critical/precision room preparation
(computer rooms/labs) requiring close tolerance control of
temperature and humidity. The conditioned space should be
well insulated and include a vapor barrier. The installer should
ensure that the proper insulation rating is used based on
the design of the space, which was the basis for the system
selected. The following chart is a recommended minimum
R-value (thermal resistance) to ensure optimum equipment
operation.

The vapor barrier is the single most important requirement for
maintaining environmental control in the conditioned space.
The vapor barrier in the ceiling and walls can be a polyethylene
fi lm. Concrete walls and fl oors should be painted with a rubber
or plastic based paint. Doors and windows should be properly
sealed and a door sweep used to minimize leakage. Outside or
