High PD on Remote Condensing Airedale Easicool R410A

[tseng2002]

Good Evening,

I have a problem at one of my establishments with a high PD, probably due to incorrect pipe size.
I am about to change the pipe size and hopefully correct the error.

How do i access the Admin controls in order to start the unit up and measure the PD again before Airedale come out to re-commission.

Does anyone on here have experience with these systems??

are you sure its down to incorrect pipesize?- refer to the installation manual to check length of run, check temp diff /pressure drop accross drier, 4648 is ur standard access to adj setpoints 0113 is ur supervisor level

Pipe Length - 59m (20mVertical) with 13Bends
Test results - 36.5Bar Dis, 32.5Bar Liq

Current Pipe sizes are 1/2"Liq, 5/8" Dis
17kw unit

Airedale have said that the pipe sizes are to small

as long as the manufacturers have stated the pipe sizes are wrong, did they specify the correct size,for that run
