Product Overview
Engineering Guide
Space Saver
Self Contained Water-Cooled Air Conditioner
Or Use With Remote Air-Cooled Condenser I Condensing
Section
These units are small in size, but big on performance and
features. Designed specically for applications having
limited oor space and accessibility, the VertiCool Space
Saver allows installation of a high capacity air conditioning
system with minimal room modications.
The VertiCool Space Saver has been engineered for use in
free blow plenum applications or ducted applications� The
water-cooled Space Saver can be specied in four cabinet
sizes ranging from 2 up to 15 tons. System exibility goes
even further. The Space Saver can also be congured for
chilled water utilization� When necessary the unit can be
matched with a remote air-cooled condenser or condensing
section (indoor or outdoor)�
The VertiCool Space Saver units are ideal for new
construction as well as renovation and replacement� The
foot print is one of the smallest, if not the smallest, in
the industry ton for ton� The low height and narrow width
allow it to pass through standard door ways for those
replacement and renovation projects�
• Access is from the front of the unit for components�
Easier to install, maintain or service unit�
• Access to the blower motor, belts and pulleys is from
the front� Maintenance or belt replacement is easier and
faster�
• Scroll compressors standard� Better performance under a
variety of operating conditions�
• The control box can be accessed while the unit is
operational� Provides easier access during installation,
start-up and servicing�
• Electric heat is removable from the side� Means easier
access if required�
• Water service connections are ush with the side of the
cabinet� Makes for a neater cleaner appearance when
placed in ofces or retail spaces.
• Chilled water coil connections out either side of cabinet�
Installation exibility.
• Condensate line is internally trapped� No um-sightly
trap external to the unit, faster installation and reduced
installed cost�
• Condensate can be taken out either side. Flexibility for
the installation�
• Variety of lter options. Satises more of what your
customers may want�
Pricing starts with a basic unit and you add in only those
additional features you want or need for your specic
application!

Electrical Data
The following sections provides the formulas and the data to calculate the Minimum Circuit Ampacity (MCA) and the
Maximum Fuse Size (MOP) for your specic unit conguration.
There are a variety of unit congurations. Please make sure to use the correct formulas per your conguration.
It must be noted that the formulas refer to the largest motor amps� This typically is the compressor (RLA), but it can also
be one of the blower motors (FLA)�
The data provided will cover the majority of available unit congurations. However, it should be noted that additional
combinations may be available and the factory can be contacted for this data�
Examples have also been provided for each conguration.
RLA = Compressor Rated Load Amps
FLA = Full Load Amps (Used for Blower Motors and Electric Heaters)
MCA = Minimum Circuit Ampacity (Calculated value)
MOP = Maximum Fuse Size (Calculated value)

NOTE: Largest motor amps may not always be the compressor�
MCA = (1.25 x largest motor amps) + the sum of the remaining motors
