wrench.

8. Start the equipment so that the operating pressures build

up inside the system. Check all the connectors again for

signs of leaks

a) during cooling mode

b) in heating mode.

If any bubbles form, the system has a

leak and the screw connectors must be

retightened.

All of these steps must be completed BEFORE powering on the unit. Failing to do so

could damage the unit.
