INSTALLATION

 

2.1

 

Receiving the Equipment

 

Your  CyberOne EC CW precision A/C system has been 
tested  and  inspected  prior  to  shipment.  To  ensure  your 
equipment is received in excellent condition, visually inspect 
the equipment immediately upon delivery. Carefully remove 
the shipping container and all protective packaging. Remove 
the access panels 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 equipment. Any freight claims 
must be done through the freight carrier; STULZ can assist in 

the claim filing process with the freight carrier.  STULZ ships 
all equipment FOB. Should any damage be present, notify 
STULZ Product Support prior to attempting any repairs. 
Refer to “5.0 Product Support” on page 19 of this manual 
for instructions.

 

A unit data package was sent with your unit. It contains this 
manual, a supplemental microprocessor controller manual, 
system drawings, applicable SDS’s, warranty registration, 
other  component manuals and  applicable  instructions 
based  on  the  configuration  and  options  of your  unit.  The 
data package has been placed in your unit in a clear plastic 
bag. These  documents  need  to  be  retained  for  future 
reference.

 

NOTE

 

Items that have  been  shipped loose, such  as 
controller terminal, temperature/humidity sensors, 
water detectors, etc., are shipped inside the air 
conditioner unless specified otherwise by the 

customer. A plenum box (if applicable) is shipped 
separately. Unpack and store these items in a safe 
place unless you are using them immediately.

 

 

2.2

 

Moving the Equipment

 

CyberOne EC CW systems are designed to be kept in  a 
vertical position. The unit is shipped on a skid to facilitate 
moving prior to installation. Move the unit with a suitable 

device such as a forklift, pallet jack or roller bar and dollies 
capable of handling the weight of the unit. The unit should 
always be stored indoors in a dry location prior to installation.

 

CAUTION

 

 

When moving the unit it must be lifted vertically and 
kept in a level position to prevent damage.

 

2.3

 

Site Preparation

 

CyberOne EC CW systems are designed with easy service 
access in mind. A hinged access door is provided on the 
front of the unit and removable access panels are located 
on each side. In order to have full service access to internal 
components, no permanent obstructions should be placed in 
front of the unit. See Figure 3 for the minimum recommended 
front installation clearance.

 

NOTE

 

Working clearance requirements need to be 
established prior to mounting the unit. Refer to 
local and national electrical codes.

 

 

Figure 3. 

Recommended Installation Clearance

 

 

When determining the installation location consider how you 
will route the piping and wiring into the cabinet and ensure 
access is available (see “2.7 Piping Connections” on page 
11). Pilot holes for  piping  and  wiring  are  located  on  the 
CyberOne EC CW unit based on the configuration. On an 
upflow configuration, the pilot holes are located in the top of 
the cabinet. On a downflow configuration, they are located in 

the floor of the cabinet. See the installation drawing provided 
with your unit for pilot hole locations.
