INSTRUCTIONS FOR THE INSTALLATION
CWA-2
1 : The supply voltage required for the unit is
120 VAC with a 15 A circuit breaker. If there is
one pump, provide an additional 15 A circuit breaker. If there are 2 pumps, provide instead an
additional 20 A circuit breaker.
2 : For a proper functioning of the machine, leave a 6’’ (15 cm.) minimum clear space around
the condenser to facilitate air flow.
3 : Install a tube of cooling line at the output of the pump.
4 : Install the return of the same line at the input of the tank (to create a closed circuit). Repeat
step 3 and 4 for each pump.
5 : Remove the unit from the top of the tank (always use the lifting handles to raise the unit) and
pour 3 gallons (3 X 4 liters) of glycol 100% in the tank and add water until just below the
overflow.
6 : Before plugging the pump(s)
, ensure that the installation and connections have been made to
required specification. After any adjustments, plug in the pump(s).
Important:
Never operate the pump(s) before filling the tank.
The pump(s) must always run to have a constant agitation in the tank and avoid damaging the
compressor.
7 : The level of liquid in the tank will go down until the cooling line(s) is(are) filled.
8 : Add water until just below the overflow and replace the unit on top of the tank.
9 : Switch on the unit. Note
there is a one minute delay before the unit start-up.
10 : The temperature will slowly drop until 28⁰F (factory setting) on the thermostat display.
