The June 2016 Excel manual (P/N 0467434_N) includes FW. Printed p.4-1 (PDF p.43) requires unobstructed discharge/return flues and operating temperature before stocking. Printed p.5-2 (PDF p.48) says dirty louvers impair performance. Printed pp.4-3–4-4 (PDF pp.45–46) address thermometer placement in the food-storage area. The manual is a later revision of a series first issued in 2005; it is not confirmed as the specific copy supplied with this February 2007 case.

Inference for this evidence: plastic that blocks an active case’s air path could impair cooling. The manual does not test Kyle’s plastic installation or establish the cause of a later reading after removal. Same-unit identity, operating state, placement, removal time, calibration, defrost and service records remain needed.
Owner-supplied old-case label. Use the FW family for context; do not apply specifications for replacement equipment or a 2026 refrigerant configuration to the 2007 unit.
