7) Loosen these bolts just enough to slide the old motor out;
don’t remove the bolts completely. Replace with new motor.
8) Thread terminal end of motor wire through switch box wire
opening and plug five-pin connector into switch connector. IMPORTANT: Ensure
that rubber grommet seal on harness is
properly seated to keep water out of control box.
9) Replace switch box cover.
10) Secure motor wire to fan bracket assembly using new wire ties.
11) Replace pads by installing from outside toward center
replacing center pad last.
12) Replace blade and screen to front of unit.
PUMP REPLACEMENT
MODELS PAC2K482S, PAC2K361S, PAC2K363S, PAC2K36HPVS, PAC2K24HPVS
1) DISCONNECT POWER and remove pads as shown on page 28.
2) Pump is in lower right of unit. Control box is in upper left. Locate pump wire secured to fan bracket
assembly using plastic wire ties. Cut and remove plastic ties. DO NOT CUT ELECTRICAL WIRES. (Figure 1)
3) Remove screws from control box cover. Unplug pump wire connector. Push rubber grommet on pump wire
through control box opening and remove pump harness wire from control box. (Figure 2)
4) Locate pump in lower right corner of the unit. Remove hose from pump by unscrewing hose connection.
Remove two screws holding pump bracket to the unit housing. Remove entire pump assembly from the unit.
(Figure 3)
5) INSTALL NEW PUMP BY REVERSING ABOVE PROCEDURES. (1.) Install new pump on pump bracket and attach
bracket to housing. Replace pump hose. (2.) Thread terminal end of pump wire through control switch box
and plug pump terminal into switch.
6) IMPORTANT: Ensure that rubber grommet seal is in properly seated to keep water out of switch box.
7) Replace switch box cover. Secure pump wire to fan bracket assembly using new bundle ties.
8) Replace pads by installing pads from outside toward center replacing center pad last. Replace pad flap with
screws.

VIII.TROUBLESHOOTING/REPAIR
A.Troubleshooting
Most problems encountered with a PORT-A-COOL® unit are operational problems. When determining which system
that the problem is associated with, first define the problem as several things may cause a particular problem, i.e., “the
pump is not running.” While defining the problem, a careful check of all systems should be made to fully understand the
extent of the problem.
The units consist of three systems — the fan system, the electrical system, and the water system. It is important to
determine which system of the unit the problem is associated with. Certain problems may be associated with more than
one system.
With an understanding of all the systems of the PORT-A-COOL® unit and how they depend on each other, it becomes
much simpler to define and solve any problems.
Although the PORT-A-COOL® unit is designed to be simple to maintain, it will be necessary to have some basic hand
tools (screwdrivers, pliers, adjustable wrenches, etc.) as well a volt/ohm meter for troubleshooting the electrical system.
— WARNING —
USE CAUTION WhEN TROUBLEShOOTING OR REPAIRING ELECTRICAL
COMPONENTS. ENSURE ThAT ALL POWER IS DISCONNECTED FROM ThE UNIT
BEFORE ThE COOLING PADS ARE REMOvED TO GAIN ACCESS TO ThE FAN.
B.RepairandReplacementProcedures
Ensure that all water is removed from the PORT-A-COOL® unit and all power is disconnected. Remove all
impediments to access the component you are checking or replacing.
REPLACING ThE COOLING MEDIA (PADS) (All Models)
CAUTION - DISCONNECT POWER BEFORE PERFORMING ThIS OPERATION
The flap must be removed to allow access to the cooling pads. Start with the center pad, which should
be tilted out from the top and lifted out of the drain trough. The two pads to either side of the center pad
may then be removed in the same manner. To remove the two outside pads, they must first be pulled
sideways toward the center of the PORT-A-COOL® unit until they clear the side retainer before removing in
the same manner as the other pads.
Locate the set screw
in the rear of the unit
on the upper right
side
Remove set screw
and lower front flap
to vertical
position (see
illustration)
48 x 12 x 6
5 pads
Once the front flap
is moved, grasp the
right pad and tilt out
at a 90 degree angle
(see illustration).
Pull the pad up to
remove from unit.
Repeat for other
pads.
