Oh the horror!!!

[monkey spanners]

Got asked to look at a couple of coldrooms installed 4 months ago that have been giving trouble......
Second hand stuff, 3 months warranty.....
Heres a list of what i've found so far.
coldroom 1
Panel upsidedown, 20mm hole in bottom of panel, 3x20mm holes in top of panel, incomming swa cable no gland just stuffed through hole, 2 incomming syy cables not made off just stuffed through hole, panel full of water due to holes shorted out compressor 3ph breaker and contactor, main switch cracked, 1994 vintage R12/R22/R502 unit running on R404A, old mineral oil visible in sightglass, syy cable not made off earthed in evaporator, no clips on the pipework, no isolators on the condensing unit, no solenoid valve, 053 drier seems a bit small for field built system (2hp unit), no labeling of refrigerant type/weight, 20mm hole into comp lecky box,
coldroom 2
repeat of above plus 4 extra hole in bottom of panel, 32a breaker running 2.5mm cable to comp (6a load), leaky comp oil sightglass, leaky rotalock valve on reciever, compressor fault/ seized, R404A with mineral oil.

While you are here......
coldroom 3
would not get below 14c, should be 4c. Found defrost heater wired to permanent live no stat, it was only the unit running that stopped it catching fire, drier in backwards, no isolator, fan catching on condenser and blade bent, internal tev with distributor, hole in the bottom of control panel the size of a letter box.

The installing company have supplied a Hammerite rebuild compressor to replace the duff one.

I'm sure there is more to come.....

Cheers Jon
