Uei Test Instruments 520KIT Furnace Installation Test Kit

Product Description

The UEI TEST INSTRUMENTS 520KIT is a comprehensive furnace installation and maintenance test kit designed to meet the documented startup requirements found in most residential and light-commercial furnace installation manuals. The kit centers on the DL579 True RMS multimeter and the RLD15B refrigerant leak detector, supported by a full suite of wireless probes covering pressure, vacuum, pipe clamp temperature, and humidity. Measurement ranges span -328 to 2462 degrees F for temperature, 0 to 20000 microns for vacuum, and 0 to 725 PSIG for pressure. The entire kit ships packed in the UEi AC550 tool backpack, which features a waterproof base, two compartments, inner pocket options, and a D-clip for jobsite mobility.

This kit is intended for HVAC technicians performing new furnace startups, seasonal maintenance, or refrigerant system commissioning. It supports superheat, subcool, and vapor/liquid saturation readings in the 32 to 180 degrees F range, making it practical for split-system and package unit service as well as furnace-only installs. The wireless probe architecture reduces cable clutter in tight mechanical rooms and attic installs. The included batteries (four AAA and nine AA) power all wireless probes and meters out of the box. Technicians working under warranty-documentation requirements will find the hold, min/max, and dual-display functions on the DL579 particularly useful for logging readings at the time of installation.

• Multimeter rated CAT IV 300V / CAT III 600V; ETL listed to cETLus and IEC 61010-1:2012; RoHS and CE compliant; FCC/IC compliant
• Supports superheat, subcool, and vapor/liquid saturation calculations (32 to 180 degrees F range)
• AC550 tool backpack with waterproof base and two compartments included; batteries for all components included

Compatibility

Designed as a startup and maintenance instrument kit compatible with most residential and light-commercial gas furnace installations where documented initial-install readings are required by the equipment manufacturer warranty.

Installation Notes

This kit is installed and operated by licensed HVAC technicians. Before connecting any electrical test leads, de-energize the equipment at the disconnect and verify absence of voltage per applicable NFPA 70 (NEC) requirements. When using the vacuum gauge probe on a refrigerant circuit, recover refrigerant in accordance with EPA Section 608 regulations before opening the system. The leak detector probe tip should be replaced per manufacturer guidelines to maintain rated detection sensitivity.
