Check and clean the strainers on a regular basis.
9.7. DOORS
Maintain water ‐ tight integrity and replace doors as needed, to prevent loss of freezer efficiency. As a
general rule of thumb, each door weigh 14 lbs brand new, but can get up to 30 lbs due to the ingress of
water. Change doors every 7 years, or as necessary.
A precaution to take is that if any gasket screws are replaced they should not be any longer than the
screws originally supplied by RS Cryo. If a longer screw is added it may go through the UHMW backing
and water will be able to get to the insulation.
Door Seals
The door seals or gaskets are precut, spun polyester strips. They are attached with stainless steel hold ‐
down strips and screws. Should a gasket become excessively warped, cut, or cracked, allowing vapor
leakage, it should be replaced.
See Section 11 ‐ Spare Parts List for the specific gasket required. To replace it, remove screws hold ‐
down strips and screws. After making sure the gasket guide is clean, install new gasket in its place, with
existing hold
‐ down strip and screws. Do not force the screws tight!
Door Safety Switch
The adjustment of the door safety switch actuation is done in the following sequence:
1. Make sure power is turned OFF
2. Loosen the set screw that fastens the microswitch arm to the microswitch shaft. Be sure the
shaft does not turn when the door is raised and lowered.
3. Raise the upper door almost half open and retighten the set screw on the microswitch shaft.
Correct adjustment is when microswitch clicks when door (latch area) rotates out about 10
inches and
again when closing door to about 5” from fully closed position. Readjust switch until
this adjustment is attained. Use silicone grease to lubricate microswitch shaft every three (3)
months.
Door Hinges
Replace if door starts sagging.
Rivnuts
To remove rivnut, very gently cut the head off with a small chisel. Then take a flat punch and push
remaining part of rivnut into the hole. Do not try and remove it because it will not bother anything and
you will damage the area for the new rivnut. Install rivnut with a rivnut tool.
Note: rivnut tool can be ordered from RS Cryo .
9.8. HEADERS AND ORIFICES
The injection headers are positioned so the nozzle orifices are pointing 20° from straight down and in
the direction of the fan closest to it.
