3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW: ....................... Colorless, odorless liquid. Toxic fumes released in fire situations.
POTENTIAL HEALTH EFFECTS: ................. (See Section 11 for toxicological data.)
EYE: ...................................................................... May cause slight transient (temporary) eye irritation. Corneal injury is unlikely. Mists may
cause eye irritation.
SKIN: .................................................................... Prolonged contact is essentially nonirritating to skin. A single prolonged skin exposure is not
likely to result in the material being absorbed through skin in harmful amounts. Repeated
exposures may cause flaking and softening of skin. May be absorbed in potentially harmful
amounts when applied in large quantities to severe burns (second or third degree) over large
areas of the body as part of a cream or other topical application. Absorption under such
circumstances can elevate serum osmolality and may result in osmotic shock.
INGESTION: ........................................................ Single dose oral toxicity is considered to be extremely low. No hazards anticipated from
swallowing small amounts incidental to normal handling operations.
INHALATION: .................................................... At room temperature, vapors are minimal due physical properties. Mists may cause irritation
of upper respiratory tract.
SYSTEMATIC: .................................................... (OTHER TARGET ORGAN) EFFECTS: Repeated excessive ingestion may cause central
nervous system effects.
CANCER INFORMATION: ............................... Did not cause cancer in long-term animal studies.
TERATOLOGY (BIRTH DEFECTS): .............. Birth defects are unlikely. Exposures having no adverse effects on the mother should have
no effect on the fetus.
REPRODUCTIVE EFFECTS: ............................ In animal studies, has been shown not to interfere with reproduction.
4. FIRST AID
EYE: ...................................................................... Flush eyes with plenty of water.
SKIN: .................................................................... Wash off in flowing water or shower.
INGESTION: ........................................................ No adverse effects anticipated by this route of exposure incidental to proper industrial
handling.

Introduction
Operating Features
Danger! It is very important that you read and understand this manual before
operating the reel! Failure to follow the procedures and cautions in this manual
could lead to injury or possible death!
The DRYAIR hose reel’s primary purpose is dispense and collect fluid
circulation hose on job sites…primarily with respect to ground thaw and/or
concrete cure operations.
The hose reel includes the following controls
• Spool directional controls
• Momentary foot switch for Load or Unload application.
•The drive is always engaged and braking controls are automatic.
Therefore, there are no brakes to engage or disengage
Drive Features & Power
Requirements
•The reel can be run off a 115VAC, 15 amp circuit.
•Reel power and directional control is handled through two toggle
switches. One controls Power - On/Off, the other controls the Mode -
Load/Unload.
•The reel motor is a single phase 3/4 horse electric motor which produces a reel speed of 18 RPM.
•Drive and motor protection against inertial forces is provided by an adjustable torque-limiter clutch located between the motor/gear box
and the reel spool. The torque limiter clutch provides quick braking action and a smooth interface with the spool’s high inertial forces.
Reel Capacities
•The HR2250 Hose Reel comes with a 1500 feet hose packages of 3/4” hose (4 hoses x 375’=1500’). The HR2250 Hose Reel is designed
to carry up to 2250 feet so that 5 (5 hoses x 375’=1875’) and 6 (6 hoses x 375’=2250’) hose pachages are also available upon request.
Transportation & Storage
•The reel can be transported by common carrier. The reel can be loaded using a forklift (accessible on 2 sides - front and back).
•A transport trailer is also available with a heat unit.
•As the reel is remote and not connected to the heating system, it can be stored out of the way or off the site when it is not needed.
•A tarp cover is provided to ensure weather and UV protection for the fluid circulation hose.

1. Torque Limiter Clutch
•The Torque limiter protects the drive line
from damage due to overload conditions.
The driven center member slips on non-
asbestos friction discs during overload
situations in the drive line.
•Torque Ratings
GLI Model 350 w/ two springs
- minimum: 60 lb.-ft.
- maximum: 190 lb.-ft.
Please note that the torque ratings are
estimates. Actual torque capacity may
vary significantly depending on many
factors. Field conditions such as oil,
humidity, water and temperature as well
as the frequency and duration of
slippage all affect torque capacity.
Although the torque limiter clutch is factory set
at Dryair, periodic adjustment may be
required. It is recommended the torque
setting of the clutch be checked twice per season (see “Maintenance” section). With prolonged use, the two friction disks, located on
either side of the A-plate sprocket, will eventually show wear.
•It is important that the torque limiter clutch is adjusted properly. If the clutch slips too easily, the spool will take too long to stop and
hose will pile up on the reel. If the clutch does not slip at all, the protection on the Altivar drive will take over and the spool will again
take too long to stop.
Note: A visual check may be required to confirm whether it is the clutch that is slipping or the motor.
See “Maintenance - Torque limiter adjustment” section of the operators manual for Torque Adjustment & Run-In Procedure.

Maintenance 5-1
Maintenance
Danger! It is very important that you read and understand this section before operating the hose reel! Failure to follow the procedures and
cautions in this manual could lead to injury or possible death!
Precautions
Electric shock will result in death or serious injury.
•The user is responsible for conforming to all applicable code requirements with respect to grounding all equipment.
•Many parts in this drive controller, including printed wiring boards, operate at line voltage. DO NOT TOUCH. Use only electrically
insulated tools.
•DO NOT touch unshielded components or terminal strip screw connections with voltage present.
•Install and close all covers before applying power or starting and stopping the hose reel.
•Before servicing:
-Disconnect all power.
-Place a “DO NOT TURN ON” label on the drive controller disconnect.
-Lock the disconnect in the open position.
•Disconnect all power including external control power that may be present servicing the drive controller. WAIT 15 MINUTES for the
DC bus capacitors to discharge. Then follow the DC bus voltage measurement procedure beginning on page 5 of the “ALTIVAR 11
Adjustable Speed Drive Controllers Start-up Guide” to verify that the DC voltage is less than 45 Vdc. The drive controller LEDs are
not accurate indicators of the absence of DC bus voltage.
Auto Resets
The drive controller is factory set and will reload its factory default settings each time the AC line is connected. It will also automatically
start when recovering from a series of different faults.
Manual Resets
ELECTRIC MOTOR
Gound Fault
If a fault occurs due to a prolonged overload, overvoltage, undervoltage or phase failure, the control must be manually restarted. The control
can be restarted by:
1) Disconnect AC power and wait for at least 30 seconds for drive controller to power down.
2) Reconnect the AC power. This will re-initiate the factory default settings.

Maintenance 5-2
Electric Motor
•The electric motor used to drive the reel is a Marathon.
•No regular maintenance is required.
•Make sure that the motor is not in prolonged contact with moisture during operation
or storage.

Maintenance & Operation
WARNING
Oil, housing, and other components can reach high temperatures during operation, and can cause severe burns. Use extreme care when
removing lubrication plugs and vents while servicing the unit.
•Do not operate the unit without making sure it contains the correct amount of oil. Do not overfill or underfill with oil, or injury to
personnel, unit, or other equipment may result.
•For proper operation in subzero conditions, it is mandatory that the
following oil be used:
“Spartan EP 320 industrial gear oil”
…any other gear oil will void warranty!
Oil Filling Procedure
•Remove Fill (#-1) and Breather Plug (#-2).
•Clean threads on the removed plugs and the plug holes with degreaser.
•Fill gear box with the recommended lubricant (see above) to a level near the center line of
the uppermost horizontal shaft or until lubricant comes out of the oil level plug hole.
•Install plugs secure in gear case.
Break-In Period
After the first 100 hours of operation, drain out initial oil, flush out the gear case with an approved non-flammable, non-toxic solvent, such
as Whitmore’s Flushing Oil (#06802030) or Medallion Flushing Oil Kosher (#06812010), and refill. Thereafter, oil should be changed at
least every 2500 operating hours or every 6 months - whichever occurs first.
Note: Oil should be changed with greater frequency if unit is used in severe environments (dust or high humidity).

Maintenance 5-3
Torque limiter adjustment
•Although the torque limiter clutch is factory (Dryair) set, periodic adjustment may be required. It is recommended tha torque setting of
the clutch be checked twice a season. With prolonged use, the two friction disks, located on either side of the A-plate sprocket, will
eventually show wear.
•It is important that the torque limiter clutch is adjusted properly. If the clutch slips too easily, the spool will take too long to stop and
hose will pile up on the reel. If the clutch does not slip at all, the protection on the Altivar 11 drive will take over and the spool will
again take too long to stop.
Note: A visual check may be required to confirm whether it is the clutch that is slipping or whether it is the Altivar 11 drive that is automati-
cally adjusting in an overload situation.
•Check that the clutch is adjusted properly with the following procedure:
Physical check
•With no power being applied to the reel, grip the edge of the spool plate and
apply full upward force, making sure that you are lifting with your legs and
not your back.
•You should be able to cause the clutch to just slip with full lifting force.
•If the clutch does not slip or slips too easily, refer to the “torque adjust
procedure”, below.
Torque adjust procedure
•Insure that the adjusting nut is in a finger tight position.
•If the adjustment nut is tighter than finger tight, loosen and complete previous
step.
•Match mark the adjusting nut with the hub. Using a torque wrench tighten the
adjusting nut to 90ft*lb.
After the break-away torque is set, bend the tabs of the lock washer over the hex
flats of the adjusting nut.
Note: The torque limiter clutch nut requires a reasonable amount of force to adjust.
Use a torque wrench that provides you with at least 18” of leverage.
Run-in procedure
•If the torque has been taken apart and reassembled or friction disks have been
changed, it is recommended that the clutch be “run in” by “slipping” the
center member (sprocket).
•Insure that the adjusting nut is
in a finger tight position.
•Match mark the adjusting nut
and hub.Advance the adjusting
nut ¼ turn from finger tight.
•Slip the torque limiter sprocket
for 8 minutes at full RPM.
•Refer back to the “Torque
adjust procedure” for final
readjustment.
