4. Push one end of the gas line firmly into the orange collet fitting on the Gas Regulator
unit. Push the other end of the gas line firmly into the black collet fitting in the panel
on the rear of the Mega-Catch™ unit (see figure 3.2). Gradually turn on the CO
2
gas by
turning the wheel on the top of the Gas Cylinder in an anti-clockwise direction.
5. Check for gas leaks from the Gas Cylinder, the Regulator and the gas line using a small
quantity of liquid detergent/soap thoroughly stirred in some water (simply brush or pour
this over the items to be checked). A gas leak can be detected by the appearance of
bubbles. If a leak is detected then turn off the CO
2
gas by turning the wheel on the Gas
Cylinder clockwise. Then disconnect the Gas Regulator and check that the “O” ring seal
is in place and is undamaged and then repeat the process. If there is still a leak from
the Gas Cylinder or the Gas Regulator refer to your gas supplier (see page 13, CO
2
Gas
Supplier section.) or email us ([email protected]).
6. To remove the gas line simply use two fingers to push the sides of the plastic collet
fitting inwards then, using the other hand, firmly pull the gas line out of the collet
fitting. If the line is damaged replace it. If however the damage is restricted to the end
of the line simply cut out the damaged area. (Note: the collets are the orange fitting
at the Regulator connection and the black fitting at the Trap connection). See figure
3.2.
ATTENTION: BEFORE INSTALLING OR REMOVING THE GAS REGULATOR ALWAYS ENSURE
THE GAS IS TURNED OFF BY TURNING THE ON/OFF WHEEL ON THE GAS CYLINDER
CLOCKWISE.
Operation of Variable Quantity Slow CO
2
Gas Release System
You can adjust the quantity of CO
2
gas being released from the ULTRA Trap by a simple touch
of the GAS SELECT button on the Programmable Timer. When the power is first turned on the
Trap automatically selects setting # 1 which is the lowest gas usage quantity. The GAS SELECT
button should be touched once to move to the next setting (indicated by the red light glowing
on the setting chosen). Touch the GAS SELECT button for the number of times necessary to
move to the setting # you wish to select.
Remember to reset the setting # after each time the power is switched off.
On setting # 1, a 20lb (9kgs) CO
2
Gas Cylinder can be operated continuously (i.e. 24 hours per
day) for over 6 months. Continuous use of the Trap on higher settings can waste CO
2
gas. We
recommend that the Trap be operated for no more than 8 hours a day at times so as to coincide
with peak mosquito activity. This might be increased to 12 hours a day if you are experiencing
a particularly heavy infestation of mosquitoes.
