Sub-Zero® (345CA) Instructions
1. Turn engine & A/C on
Start car and turn on A/C to its highest setting, MAX COOL.
2. Determine if compressor is on
With the A/C on, determine if the compressor clutch is engaged (cycled on).
TIP – If the compressor is not cycling on, add ½ can of refrigerant using instructions 5–8.
If the compressor still does not engage, repairs may be necessary.
3. Find service port
Locate the vehicle’s low-pressure port on the larger-diameter aluminum tubing, between the compressor and evaporator. Remove the plastic cap from the port and save. Visit our port locator for help locating your low-pressure service port.
4. Remove shipping disk & hose
Unscrew the charging hose from the can and set can aside. Remove red and white shipping disk by unscrewing and discard.
5. Attach quick-coupler
Attach the quick-coupler fitting on the end of the recharge hose to the low-pressure port (the only port onto which it will fit) by pulling the connector ring back as you push the fitting onto the low-pressure port.
NOTE: DO NOT push down on blue push-button dispenser. This can release refrigerant from the A/C system!
6. Read pressure
Push down on the blue push-button dispenser. This allows refrigerant to flow into the vehicle. Hold can upright to charge, shaking and rotating it from 12 o’clock to 3 o’clock every few seconds. Continue process, releasing the blue push-button dispenser every 10 to 15 seconds to check system pressure with the “V” range on gauge, until the system is fully charged (i.e., the psi is in the GREEN zone) or the can is empty. BE CAREFUL NOT TO OVERCHARGE YOUR SYSTEM! For California version (345CA), use instructions above. (NOTE: You can lock the push-button dispenser in the “charging” position by turning clockwise ¼ turn. To unlock, simply turn counterclockwise ¼ turn.)
7. Connect hose & can
Pull ring back to disconnect the recharge hose from the vehicle and screw the can on to recharge hose. Connect recharge hose to low-pressure port (refer to instruction #5). (CAN IS NOW READY FOR USE.) DO NOT REMOVE HOSE FROM THE CAN UNTIL CAN IS EMPTY.
Pull ring back to disconnect the recharge hose from the vehicle and screw the can onto the recharge hose (CAN IS NOW READY FOR USE). DO NOT REMOVE TRIGGER FROM CAN UNTIL EMPTY. Reconnect the quick-coupler to the low-pressure port. Shake the can well. Hold the can upright to charge, shaking and rotating it from 12 o’clock to 3 o’clock every few seconds. Squeeze trigger to dispense contents. Continue this process, releasing trigger every 10–15 seconds to check system pressure with the “V” range on gauge, until the system is fully charged (i.e., the psi is in the GREEN zone) or the can is empty. BE CAREFUL NOT TO OVERCHARGE YOUR SYSTEM!
It is possible that the can will not be empty when finished. In this case, after disconnecting it from the vehicle, simply leave the recharge hose on the can and store it in a cool, dry location. If the can is empty, hold it upside down for one minute to dispense any remaining product. Disconnect from the vehicle, then simply unscrew the can and discard. The recharge hose may be used again with another can of R-134a refrigerant with a threaded cap. Replace the plastic cap you removed from the port during instruction #3. For California Version (Model 345CA,) DO NOT DISCARD. Return to place of purchase for Deposit/Refund.
