342000 Refrigerant Service Solution

REPLACING THE SOURCE TANK

Periodically, the source tank on the back of the unit will run out of refrigerant.
The internal storage vessel contains enough refrigerant for several jobs, but
it’s important to replace the tank soon after the message is displayed so that
you don’t deplete the refrigerant supply in the internal vessel.

1. The message CHECK SOURCE TANK is displayed.

2. Close the source tank valve. Disconnect the black tank hose from the

source tank valve.

3. Release the tank strap and remove the tank from the back of the unit.

4. Before installing a new source tank, test the contents for contamination

following instructions on page 12, “Testing Source Tanks.”

5. Place a new disposable tank on the platform and secure it with the tank

strap. The tank must be set up to supply liquid—usually this means it is
inverted (see page 11, step 9).

6. Connect the black tank hose to the tank’s fitting. Open the tank valve.

7. The automatic refill will add refrigerant to the internal storage vessel as

the unit works. However, if you want to fill it immediately,

a. press MAIN MENU,

b. press SCROLL MENU, then

c. press the TANK REFILL key.

ELECTRICAL PROTECTION

The 342000 monitors voltage and disables circuitry if the voltage drops below
103.5 volts or increases above 135 volts. It also detects incorrectly wired
connections and warns of the potential hazard. Additionally, the 342000 is
protected by circuit breakers located on the back panel (see page 7). If the
circuit breaker trips, all power to the unit is lost. Press the circuit breaker
button to reset.

To reduce the
likelihood of
leakage, the
black hose
should always
be connected
to a source
tank.
