Safety First (Quick!)

• PPE required: Chemical-resistant gloves, safety glasses, long sleeves, respirator if in confined space, hearing protection as needed.
• Ventilation: Always ventilate enclosed spaces. Solvent vapors are flammable and can cause dizziness.
• Fire safety: Keep away from ignition sources; store solvent cements in approved containers.
• First aid: In case of eye contact, flush with water and seek medical help immediately.

Tools & Materials (Field kit)

• PVC conduit cutter or fine-tooth hacksaw
• Utility knife and deburring tool
• Lint-free rags
• PVC primer (purple) — use when required by AHJ or manufacturer
• Conduit-rated solvent cement (match PVC/CPVC as required)
• Applicator brushes (if not included in can)
• Tape measure & marker
• Gloves, safety glasses, respirator
• Camera or phone for inspection photos (recommended)

Quick Reference: Typical Minimum Cure Times (non-pressurized, 60% RH)

• ½"–1": 15–30 min
• 1¼"–2": 30–60 min
• ≥3": 1–2 hrs
• <40°F (4°C): allow longer — consult product datasheet (may be up to 24 hrs for full strength)

Always follow the cement manufacturer’s datasheet for precise cure times and for backfill/pull/pressure guidance.

Step-by-Step Procedure (Follow exactly)

1) Prepare & Inspect

1. Confirm all materials are UL/CSA-listed for electrical conduit and match project spec.
2. Verify labels on cement/primer: product name, lot, shelf life.
3. Inspect conduit and fittings for cracks, deformities or contamination.

Preparation / Material Check

• Technician checking product labels and items laid out.
• Callouts: A — Product label visible; B — No damage to fitting; C — PPE on technician.

2) Cut Square & Deburr

1. Measure and mark conduit to length.
2. Cut with a ratchet cutter or saw at 90° to the conduit axis.
3. Deburr inside and outside of cut; remove any plastic shaving.
4. For conduits ≥2", add a 15–30° bevel on the outside edge for smoother seating.

Square Cut & Deburr

• Square end, inner burr removed.
• Callouts: A — Square cut; B — Deburred inside; C — Beveled edge (if required).

3) Dry-Fit & Mark Insertion Depth

1. Dry-fit conduit into fitting until it seats fully at the stop.
2. Mark the insertion depth on the conduit with a marker for visual verification during assembly.

Dry-Fit & Depth Mark

• Conduit partially seated; depth mark visible.
• Callouts: A — Seating stop inside fitting; B — Depth mark on conduit.

4) Clean Mating Surfaces

1. Wipe mating surfaces with lint-free rag.
2. If oily/greasy, use PVC cleaner or denatured alcohol; allow surfaces to dry.

 Cleaning Surfaces

• Technician wiping socket and conduit.
• Callouts: A — Clean socket; B — Clean conduit OD; C — Rag and cleaner visible.

5) Apply Primer (When Required)

1. If local code/AHJ or manufacturer requires primer, apply an even coat to conduit OD and fitting socket.
2. Primer should soften the surface — purple primer provides visual evidence for inspectors.
3. Let primer set briefly per product instructions (usually seconds).

Primer Application

• Purple primer on socket; visible wet area.
• Callouts: A — Primer bead inside socket; B — Primer on conduit OD; C — Mark inspector photo.

6) Apply Solvent Cement

1. Shake/condition can if required and open carefully.
2. Apply cement evenly: coat conduit OD fully to insertion depth, apply a thin coat inside socket.
3. For larger diameters, ensure heavier-bodied cement and adequate gap filling.
4. Work quickly — solvent action is time-sensitive.

Cement Application

• Brush/dauber applying cement to conduit and socket.
• Callouts: A — Full-depth cement on conduit; B — Thin inside-socket coat; C — No pooling.

7) Assemble: Insert + Twist

1. Immediately insert conduit into fitting to the marked depth.
2. Give a ¼-turn twist while pushing to evenly distribute cement.
3. Hold firmly for 30 seconds (or as specified by product) to prevent push-back.
4. Do not re-twist after seating.

Assembly & Hold

• Technician holding joint after insertion.
• Callouts: A — Depth mark at flush; B — ¼-turn direction arrow; C — Holding hand position.

8) Clean Excess & Initial Cure

1. Wipe excess cement with lint-free rag. Avoid smearing primer into visible test areas required by AHJ.
2. Allow initial set time before handling (~30–60 min depending on diameter and temp).
3. Take inspection photos for records (especially for underground/wet locations): show primer, product labels, and joint seating.

Finished Joint Photo (for record)

• Completed joint, close-up showing clean bead and depth.
• Callouts: A — Clean joint bead; B — Depth mark flush; C — Photo timestamp sticker (optional).

Troubleshooting & Remediation

• If conduit won’t seat: Check for burrs, out-of-round conduit, or oversized fitting. Recut and re-deburr if needed.
• If excess cement pools inside: Remove before full cure; if cured and interfering with conductors, replace the fitting.
• If primer/cement beads do not wet the surface: Materials may be incompatible or surfaces contaminated — do not use; replace parts.

Inspection Documentation (What to capture)

• Photo of product labels (cement/primer lot and shelf life)
• Photo of primer application (purple visible if used)
• Photo of depth mark and seated joint
• Photo of finished joint and surrounding substrate (for buried/wet runs)
• Log: technician name, date, joint ID/location, product used (name & lot)

Trainer Competency Sign-Off

I confirm the technician has demonstrated the above procedure to satisfactory standards.

Trainer: ________________________ Date: __________ Notes: ______________________

Technician: ______________________ Date: __________ Notes: ______________________

Photo Composition Guidance (to create clear annotated images)

• Use daylight or a bright LED work light. Avoid harsh shadows.
• Close-ups: fill frame with the joint element; resolution ≥12MP for cropping.
• Orientation: mix portrait for full assembly shots and landscape for close-ups.
• Annotate photos with arrows/circles in your phone gallery app or an image editor. Include a ruler or tape measure for scale if helpful.

Additions & Customization (for your company)

• Add company branding and safety procedures tailored to your site (hot work, confined space, fall protection).
• Insert manufacturer-specific cure charts and product datasheets as an appendix.
• Local code note: include AHJ primer requirement if your area mandates it.
