ABOUT COMPU-KOOL -AYAN IV SERIES
The COMPU-KOOL –AYAN IV SERIES is designed to provide localized temperature and humidity
control in high heat load areas found in commercial and industrial setting. This free standing
unit operates independently of the central air conditioning system and provided auxiliary
cooling to a pre-selected environment. Completely factory assembled, piped, and wired, the
COMPU-KOOL offers flexibility features to meet virtually any floor plan.
Maintaining consistent temperature and humidity conditions requires quick response to
changing heat loads in the computer room. COMPU-KOOL meets this challenge through
constant fan operation, thus preventing stratification of room air. COMPU-KOOL constantly
monitors the return air steam for any change in space conditions; the appropriate air
conditioning mode is quickly initiated. All cooling, heating, humidification and dehumidification
controls are fully automatic. To keep noise levels at a minimum, thermal and sound barrier
insulation fully line cabinet. COMPU-KOOL is available as air, water or glycol cooled system.
COMPU-KOOL answers the need for localized environmental control.

connection could be brought from the rear top panel of the unit. Provide isolation shut off
valves for all pipes external to the unit.
AIR FLOW
The return air is drawn through the back of the unit and discharged into the room through the
front of the unit.
CONNECTIONS
In connecting the unit, five items must be addressed. They are
1. Structural Support
2. Electrical Supply
3. Condensate Drain Connection
STRUCTURAL SUPPORT
The unit can be installed directly on the floor or on the raised floor without the need for any
special support. The floor should be level.

Revision: 01 02/29/2016 Page 9
ELECTRICAL SUPPORT
A fused disconnect of a HVAC approved circuit breaker must be field provided and installed per
the National Electric Code. There is access to the unit for electrical connection through the unit
bottom or the lower portion of the unit back. Be sure unit is properly grounded.
A fused disconnect must be provided for the air cooled condenser for air cooled condenser for
air cooled units and dry fluid cooler for the glycol cooled units.
CONDENSATE DRAIN CONNECTION
A submersible water pump is placed on the drain pan and will active when the pump detect
water condensation and pump the water condensation out from the condensate line located
rear top panel of the unit. Field install must connect the condensate line to building drain
system properly according to the building guidelines. See Figure 5 - Back view for location of the
condensate water pump.
WATER CONNECTIONS
For water cooled units where water supply shall be either city water or cooling tower. Provide
a shut off valve in supply and return line for isolation.

START-UP AND TEST PROCEDURE
A. With all power to unit off- Check that ALL WIRING IS CORRECT.
Check that properly sized fuses are installed in the disconnect switch. Correct fuse size
and minimum circuit ampacity are listed on the unit nameplate. Now, check the wiring
connections in the Main Control Panel to see if they are tight. It is best that this be
checked prior to operating the machine. After checking, close the Main Control Panel
cover and proceed as follows:
Microprocessor Control Panel –With the system switch in the “OFF” position, apply
power to the unit. The “Power ON” light should illuminate.
B. Check for Correct Phasing
The equipment should now be checked for correct phasing required to make the blower
motor turn in the correct directions. For this test it is necessary to open the right side
doors of the unit to observe the blower and blower motor. Now, momentarily switch
the system switch to the “ON” position and then back to “OFF”. The blower motor with
have started and it is therefore possible to determine rotation. On Compu-Aire units,
the blower should be rotating in a CLOCKWISE direction. Heaters and humidifiers are
not affected by phasing.
GENERAL MAINTENANCE
General maintenance must be performed in regular intervals to provide continued operation of
the entire unit. The maintenance intervals must be determined site specifically. Use the
maintenance checklist at the end of this manual when performing maintenance. Typically, air
filters should be replaced no less than two times per year.
The filters should be checked and changed periodically. When they become dirty, an alarm is
activated the filter pressure switch. If the filters are dirty, they must be changed for efficient
operation of your system. To check the alarm indicator, cover approximately 75% of the return
air opening; the alarm should energize. If the alarm energizes prematurely or does not energize
when it should, adjust the filter switch. All doors to machine should remain closed before
determining whether an adjustment is necessary. Spare filters should be kept in stock. Filters
should be checked monthly and replaced if necessary.
The maintenance intervals must be determined site specifically. Use the maintenance checklist
provided if available when performing maintenance. In order to ensure that the system runs
trouble free for many years, a follow-up maintenance program (consisting of a minimum of two
inspections per year) should be set up. A qualified service mechanic should carry out this semi-
annual inspection. The main power supply must be disconnected and locked off to avoid
accidental startup of the equipment.

Revision: 01 02/29/2016 Page 15
(1) Check electrical components and tighten any loose connections.
(2) Check all wiring and electrical insulators.
(3) Check contactors to ensure proper operation and contact point for wear.
(4) Check that fan motors (if applicable) are operational, ensure fan blades are tight and all
mounting bolts are tight.
(5) Ensure that the condenser surface (if applicable) is cleaned and free of dirt and debris.
(6) Check the operation of the control system. Make certain that all of the safety controls are
operational and functioning properly.
(7) Check chilled water valve system. Make sure that all mechanical joints and flare nuts are
tight.
Service Parts Availability
Genuine replacement service parts should be used whenever possible. Parts may be obtained
by contacting your local sales representative or authorized distributor. Contact us 562.945.8971
