XLP3 EVAPORATIVE CONDENSERS
INSTALLATION
Automatic Bearing Greasers (Optional for Belt Drive
Fan System Units Only)
1. Verify the mounting brackets are factory installed.
2. Fill the extended lube lines with Frick compatible water re-
sistant grease using a manual grease gun. See the “Fan Shaft
Bearings” in the Maintenance section of this manual.
3. Thread automatic bearing greasers into 3/8” x 1/4” adapters
on mounting brackets.
4. For programming, operation, and troubleshooting of the
greaser, consult the user manual shipped with the greaser.
This manual is also available through your local Frick Rep-
resentative.

Heater Control Panel (Optional)
1. Carefully plan the location of the control panel. Measure the
factory supplied probe cord length. Do not attempt to change
the cord length.
2. After selecting the installation site, mount the control panel
with four 5/16” (field supplied) bolts through the mounting
feet on the enclosure.
3. The main incoming power hub and the main power termination
points are sized for wires based on the total nameplate kW
and voltage. The actual load for a particular installation may
be less. Either compute the actual load on the heater control
panel (the total kW of all the heaters connected to it) or use
the nameplate rating to determine the wire size required. The
field supplied branch circuit disconnect switch and the branch
circuit protective devices (fusing or circuit breaker) should be
sized per NEC or local code requirements.
4. Connect the incoming power wire conduit to the incoming
power hub provided on the control panel. Make sure the con-
nection is water tight and secure. Pull the incoming power
wire into the control panel enclosure and make connections
per the control panel-wiring diagram.
5. Connect the heater power wire conduit(s) to the heater power
wire hub(s) provided on the control panel. Make sure the con-
nection is watertight and secure. Pull the heater power wire
into the control panel enclosure and make the connections
per the control panel wiring diagram. Conduit connections
to multiple heaters should run until the conduit terminates
at the last heater. Jumpering from one heater to the next is
not recommended.
6. If the heater has a thermal cutoff, wire the cutoff back to the
terminal block in the panel per the wiring diagram. This is a
Class 1 circuit and can be in the same conduit as the power
wiring. If there are two or more heaters, connect the cutoffs
in series as shown in the wiring diagram.
7. If alternative conduit hubs are drilled, or if supplied hubs are
not used, replace the plastic protective caps inside the hubs
with steel plugs.
8. If leakage or condensation is likely to occur in the conduit
runs leading to the control panel, install a drain in the bottom
of the control panel and form a conduit loop.
9. Verify operation by following the “Stand Alone Frick Heater
Control Panel” in the Operation section of this manual.
NOTICE
1. The heater control panel should be within sight of the
heater if a disconnect switch option is selected.
2. Maintain a water level at least 2” over the heaters by
ensuring proper operation of make-up water level
control. Low water may lead to over temperature
conditions near the heater.
3. All power wiring should have a temperature rating of
167°F (75°C), and be rated for the number of wires in
the conduit.
4. The wiring should be sized for the quantity of incoming
wires in the conduit and the amperage of the branch
circuit protective device as directed by the NEC/CEC, or
any other local directives.
5.
If non-metallic conduit is used, provide a circuit
grounding conductor that meets NEC/CEC requirements.
Ground lugs are provided in the heater control panel.
