Field notes

Field notes for AC condensate plan

Practical checks to run before this calculator result turns into a site decision.

Site check

Condensate is a failure point

Cooling plans fail when buckets fill, pumps lift too high or drains are routed badly. Plan water removal before leaving the unit running.

Site check

Match pump head to the route

A pump that works on the floor may fail when pushed up to a ceiling void, across a long run or through a kinked hose.

Site check

Include inspection intervals

If the route is temporary, note who checks water, alarms, filters and hoses during the hire period.

FAQ

AC condensate plan FAQ

Short answers for UK temporary electrical and HVAC planning.

What is the AC condensate plan used for?

Plan tank emptying, gravity drain or pump route for unattended portable AC operation. It is mainly for temporary HVAC, drying, cooling and site-power planning, especially where a quick pre-check is needed before selecting equipment or changing a temporary setup.

Can this replace BS 7671 design, inspection or testing?

No. Treat it as a pre-check for the conversation or job file. Final decisions still need current BS 7671 requirements, manufacturer data, inspection, testing, risk assessment and the actual site conditions.

What should I verify before acting on the result?

Check cooling load, exhaust duct route, condensate route, compressor start current, available circuit rating and whether other site loads share the supply. If any assumption is uncertain, use the result as a prompt to investigate rather than as clearance to switch on.

What does an amber or red result usually mean?

It normally means the margin is weak, an assumption is missing, or the load should be split, staged, moved closer to the supply, reduced or checked by a qualified electrician before use.
