Use and Care Manual

Iv. MAINTENANCE & STORAGE
Very little maintenance is required on the PORT-A-COOL® unit. Cleanliness is the most important part of
a maintenance program. Keeping the unit clean will do more than any other single item to keep your unit
in peak operating condition. The rugged, corrosion-resistant construction of the unit and industrial grade
components ensure low maintenance characteristics. In exceedingly dusty or dirty environments, optional
filters are available from your distributor, or at www.port-a-coolparts.com
A. Daily Maintenance
Daily maintenance is an operational routine rather than actual maintenance. On a daily basis, the pump
should be turned off approximately 15 minutes before the fan is turned off. This will allow the cooling
pads to dry out and extend their life, helping to control the growth of mildew, mold, bacteria and other
odor causing elements.
B. Weekly Maintenance
At the end of the week or at a scheduled time, the unit should be shut down and the sump tank should
be drained. Closing the Spray Bar Adjustment Valve and opening the Drain Valve will accomplish this. If
it is desired, a hose may be attached to the Drain Valve to direct the drained water to a remote disposal
area. Once the Drain Valve is open, starting the pump will drain the unit. When the pump has removed
most of the water, a small amount will be left in some areas. The PAC2K163SHD, pac2K16HPVS, PACCYC02,
PACCYC02A, PACJS1600, PACJS2400 and PAC163SVT models come equipped with a drain plug. Removal
of the drain plug will accomplish the same results without the use of the pump.
Once the sump is drained and the power disconnected, remove the pads to allow inspection and
cleaning of the sump tank. Dust may collect in the sump tank over time. Dirt and any remaining water can
be vacuumed out using a wet/dry shop vacuum and the sump wiped clean with a cloth. Also, inspect
and clean the Inlet Strainer located on the bottom of the pump. Replace pads in correct airflow direction,
referring to label on the pads.
C. Storage
1) Drain all water from the sump tank and clean, ensuring that the pads and sump are completely dry.
2) Roll up the electrical power cord and secure it to ensure that it will not be rolled over, tripped over or
caught in equipment.
3) Cover the unit completely to prevent dust build-up and store in a dry area which also helps prevent
damage to the pads. Optional dust covers are available from PORT-A-COOL® distributors or at
www.port-a-coolparts.com.
CAUTION — DISCONNECT POWER BEFORE REMOVING PADS FROM THE UNIT

WATER SYSTEM
The water system consists of three primary elements: 1) Water Delivery System, 2) Spray Bar Assembly;
3) Pump.
The Water Delivery System consists of two sub assemblies: A) The Water Inlet assembly and B) The
Plumbing assembly.
The Water Inlet assembly is made up of three components: 1) The bulkhead fitting, 2) The float valve
connection hose and 3) The float valve. The Plumbing assembly consists of three elements: 1) Riser (PVC
components), 2) Drain Valve, 3) Spray Bar Adjustment Valve. The PACCYC01, PACCYC01A, PACCYC02,
PACCYC02A, PAC2K163SHD, PAC2K163HPVS and PAC3SVT models have no riser or drain valve.
The Spray Bar Assembly consists of two components: 1) Spray Bar, 2) Connection Hose.
The pumps that actually move the water through the delivery system are discussed in the charts below.
These charts indicate the major symptoms of problems that may be encountered with the Water System
components.
