1.0 INITIAL INSPECTION
1.1 upon receipt from the carrier, inspect the heater for possible
damage in transit. if necessary, immediately report damage to
shipping company.
1.2 Verify that the nameplate voltage, phase, wattage and catalog
number comply with the order.
1.3 The CWCB, when configured:
• as a swimming pool heater, has a catalog number
CWCB-XX-1;
• as a domestic water or dishwasher water booster heater,
has a catalog number CWCB-XX-2;
• as a hot water furnace for comfort or process water
heating, has a catalog number CWCB-XX-3.

2.0 INSTALLATION
2.1 The heater must be installed by qualified personnel to code
requirements.
2.2 ensure that the electrical power supply is the same voltage
and phase as the heater with sufficient current capacity.
2.3 the heater must be installed in a horizontal position with the
outlet at the top and the drain at the bottom.
2.4 The mounting hardware, as provided, is suitable for either floor
or ceiling mounting. note that each mounting bracket is to be
attached at the top of the heating housing by two holding bolts
(see Fig.1). Remove the two bolts and install the first mounting
bracket prior to removing the second two bolts to install the
second mounting bracket. if all bolts are removed at once the
tank may shift which will increase installation time.
2.5 Please refer to Figure 1 for dimensions. Be sure to provide
adequate space to facilitate installation and maintenance.
leave a minimum of 24" (60cm) clearance at the control
compartment (opposite side to the inlet). if the unit is to be
mounted under a table or cabinet a minimum of 30" (75cm)
from the floor to the underside of the cabinet is required for
piping.
2.6 allow space at sides for the conduit used for power supply and
for thermostat or optional equipment wiring.
2.7 Please refer to Figure 2 for component location and note the
following:
2.7.1 the circulation pump outlet is connected to the heater
inlet located at the end of the unit opposite to the controls
compartment.
2.7.2 A flow switch (optional) is to ensure that the heater will not be
energized if the flow is interrupted. Installations requiring a flow
switch include:
(a) swimming pool heating systems where the heater is
positioned above the pool water surface.
(b) Whenever the plumbing allows for the heater to be isolated
by shut off valves on the inlet and outlet.
(c) systems where the heater vessel is allowed to drain when
flow is interrupted. (Without water the built-in limit will not
perform as intended).
(d) systems where the temperature control bulb is located
away from the outlet.
If a flow switch is not used, and also for pool heating, it is best
to allow the circulating pump to run continuously.
2.7.3 Wire both flow switch and control thermostat to contacts
designated “normally open” and “common”. “normally open”
contacts open on temperature rise on thermostat and close on
flow through switch.
