HW5

Overview

The Hobart HW5 is a commercial warmer from Hobart Corporation (701 S. Ridge Avenue, Troy, Ohio 45374-0001) and part of the company's HR5/HR7 rotisserie oven and HW5/HW7 warmer platform. Hobart's own documentation treats these as one family: the Form 34046 instruction manual covers the HR5 and HR7 rotisserie ovens together with the HW5 and HW7 warmers - including setup, operation, and cleaning - and the Form 34199 (Feb. 2000) Catalog of Replacement Parts covers the same group. In a rotisserie line-up, the HW5's job is holding: keeping roasted product at serving temperature after it leaves the oven, and Hobart publishes a stacking kit specifically so an HR5 oven and an HW5 warmer can share one footprint.

Alongside the HW5, the family includes the HW7 warmer and the HR5/HR7 rotisserie ovens in electronic and programmable control versions. The HW5 designation also appears on the related HW5-4 film roll heat wrap station seen in used-equipment listings - a different application that shares the model designation.

Key Features

• Family platform: shares Hobart's Form 34046 instruction manual and Form 34199 parts catalog with the HR5 and HR7 rotisserie ovens and the HW7 warmer, so controls, documentation, and replacement parts follow one system.
• Stacking with the HR5: Hobart's stacking kit, model STCKKIT-HR/W (listed as STACKING KIT-HR5/HW5, Wasserstrom item #352250), is published specifically for HR5/HW5 combinations.
• Warm/Hold holding cycle: the family control documentation defines a dedicated holding cycle with recommended temperatures of 160°F (71°C) or 180°F (82°C), with the rotisserie continuing to turn throughout the hold.
• Manual dials plus optional 15-program control: the panel combines thermostat, rotisserie, and main power dials with an optional programmable control (addendum Form 34486, Aug. 2000) offering 15 programs - 5 menu buttons × 3 functions (Cook, Grill, Warm/Hold).
• Catalogued parts support: the Form 34199 catalog details door glass, hinge assemblies, handle components, magnets, heating elements in 208 V and 240 V versions at 2,100 W and 3,100 W, blowers with fan blades, heat shields, and vent assemblies; the SL-005-09 spring-loading part also lists the HW5 among the models it fits, and Hobart parts lists such as the HSROG parts list cross-reference the HW5 and HW7 model numbers.

Installation & Requirements

The one installation accessory Hobart publishes for this pairing is the STCKKIT-HR/W stacking kit, listed as STACKING KIT-HR5/HW5, which lets an HR5 rotisserie oven and an HW5 warmer stack in a single footprint. The sources here do not publish HW5-specific clearance, ventilation, or utility-connection figures; for setup, the Form 34046 family instruction manual is the governing document, and PartHubz makes Hobart equipment resources available at parthubz.com/equipment/hobart.

Operation

The Form 34046 family manual covers setup, operation, and cleaning for the HR5/HR7 ovens and HW5/HW7 warmers. Its control panel pairs manual dials - thermostat, rotisserie, and main power - with an optional 15-program programmable control documented in addendum Form 34486 (Aug. 2000) for the HR5/HR7 rotisserie ovens. The Warm/Hold cycle described there is the behavior a warmer exists to deliver, so it is worth understanding in detail.

Manual vs. Programmable Control

• Manual operation uses the dials directly.
• All programming is done with the thermostat, rotisserie, and main power dials in the P position; if any dial is elsewhere, the manual controls override the programmable controls.
• With all dials at P, the right display shows the code 15Pr (extended programming available) and the left display shows Program 1; at power-on the display shows Program 1 and 15Pr, with the colon flashing and the remaining cooking time shown.
• Time of day is set with the main power dial at P; it is a 12-hour clock, displayed by pressing and holding the clock key.

Programming

• Each menu button holds three functions: Cook (roasting), Grill (searing and browning, at the beginning or end of a cycle), and Warm/Hold (holding).
• Press a menu button once for Programs 1-5, twice for Programs 6-10, three times for Programs 11-15; the button's LED lights.
• Press and hold two keys simultaneously for about 2 seconds until the display reads PROG to enter program mode.
• Cook comes first: hold the temperature key while pressing up/down to set temperature (32°F/0°C minimum, 480°F/249°C maximum), then hold the time key while pressing up/down (5 hours 59 minutes maximum).
• Grill is programmed the same way where needed.
• Warm/Hold takes a temperature only - there is no time setting, and attempting one sounds the buzzer for 3 seconds.
• Press the flashing menu button to lock the settings; every function must have a value entered for the program to work.
• Verify entries by holding the menu button and pressing the function key; Warm/Hold shows temperature only, with the time display reading 00:00.

Running a Cycle

• Select the menu button, then press start: the time display counts down the total processing time, and the temperature display shows pht (preheat) until the cavity reaches 125°F (52°C), then shows actual cavity temperature while maintaining the programmed temperature.
• The probe key lights the probe icon and displays probe temperature for 20 seconds at a time.
• Holding the function keys calls up the programmed Cook temperature and time, Grill temperature and time, temperature only, or time only.
• Start/stop interrupts a cycle - heaters and the front (customer-side) lamp shut off and the key flashes; press it again to resume where the cycle left off, or use the reset key to start the programmed cycle from the beginning.
• At the end of a Cook or Grill cycle the buzzer sounds; press to silence it.
• When the cycle moves into Warm/Hold, the buzzer sounds and the operator-side lamp cycles on and off with the heaters; hold the key to silence the buzzer. The displays show actual cavity temperature and time of day until the holding temperature is reached; press to end holding.
• The rotisserie continues to turn during the hold cycle.
• Cook or Grill temperature and time can be modified before or during processing without changing the values stored in memory.

Cleaning & Maintenance

Troubleshooting

• Display reads Program 1 and 15Pr at power-on - normal on units equipped with the 15-program accessory.
• Temperature display stuck on pht - the cavity has not yet reached 125°F (52°C); the display switches to actual cavity temperature once preheat is complete.
• Buzzer sounds for about 3 seconds during programming - a time was entered for Warm/Hold, which accepts a temperature only.
• Programmed settings appear ignored - a dial not in the P position lets the manual controls override the program; set the thermostat, rotisserie, and main power dials to P.
• Buzzer at cycle end - press the indicated key to silence it; during Warm/Hold the operator-side lamp cycles on and off with the heaters until the holding temperature is reached.

Applications

• Rotisserie holding: keeping roasted product at serving temperature - 160°F (71°C) or 180°F (82°C) per the family hold-cycle guidance - after the HR5/HR7 cook or grill cycle ends, with rotation continuing through the hold.
• Stacked cook-and-hold lines: the STCKKIT-HR/W stacking kit pairs an HR5 oven with an HW5 warmer in one footprint, so cooking and holding happen in the same spot.
• Parts-backed service life: with the Form 34199 catalog covering the HW5 alongside the HR5/HR7 ovens and HW7, doors, elements, blowers, and hardware stay available as catalogued replacements.
