Large Heatpress (Clamp) [Out of Service]

Tags: #<Tag:0x00007fa491f29cb0>

Important

The appliance is out of service pending rewiring.
@joeatkin2 and @unknowndomain are working on this as of 2023-11-10

Condition Notes

The appliance appears to have had a number of previous modifications and attempts to make it operate, which have led to the installation of both 110V and 240V parts which is unsafe.

Repair #1

@Howard replaced the 110V relay with a (TE Т92Р7А22-240) 240V relay. He additionally installed a REX-C100FK02-M*AN temperature controller, which will allow it to have digital temperature control from the control panel.

Repair #2

@joeatkin2 went to look at reports the unit was not heating up and may not be safe.

Repair #3

@joeatkin2 and @unknowndomain started by checking the current state and what rewiring would be necessary to get it to pass a PAT test today.

We put to bed any questions of whether it is 110V. We have confirmed that the heater coils and all the parts designed for 230V as the heater coils have a resistance of 30.5Ω, which means the unit will have a heat output of ~1.8kW, similar to other sized units.

Calculation: 240V² ÷ 30.5Ω = 1888.5245901639 W

We are going to order parts to rewire it with a new longer flex, run-down timer, and replace the majority of the internal wires and recrimp to avoid any single insulated cabling being reachable.

Induction and Training

Induction required for safe use and knowledge of how to use it, adjust it, and what it can be used for. Currently informal.
