Product Usage Instructions

Mounting

CAUTION: Always unplug the cooler before attempting to service or open it. Do not use the switch for disconnect purposes.

1. Ensure the mounting surface is strong enough to support the cooler’s weight.
2. Loosen the screws holding the grille to the duct and slide the side sealers between them.
3. Line up the slots in the side sealers with the screws in the grille and tighten the screws securely.

Install Overflow and Drain

1. Slide the rubber washer over the drain bushing and push through the hole in the bottom of the cooler.
2. Secure it from below with the lock nut. Do not over-tighten.
3. Push the plastic overflow pipe into the drain bushing and hand tighten snugly.
4. If leakage occurs, retighten either the nut or overflow pipe until the leaking stops.

Float Valve Installation

1. Place the float valve in the bracket inside the cooler ensuring free movement.
2. Tighten the brass ring nut and connect the water tubing securely.

Water Line Connection

1. Find the closest outside water faucet for connection.
2. Connect the water tubing to the float valve, ensuring a secure connection without over-tightening.

Your Evaporative cooler

Evaporative cooling uses the principle of evaporation to lower the air temperature. Hot, dry air is passed through wetted filters and is converted to refreshingly cooled air. Norrland coolers make the best use of the evaporative process by controlling the flow of water, spreading the water evenly over the filters, and keeping a steady stream of cooled air entering your home. It is exhausted out of open windows or doors, carrying heat, smoke, and odors along with it. Norrland evaporative coolers are 80% less costly to operate than refrigerated air conditioners.

WARNING: To Reduce The Risk of Fire or Electrical Shock, Do Not Use This Fan With Any Solid-State Speed Control Device
CAUTION: ALWAYS UNPLUG THE COOLER before attempting to service or open it. Do not use the switch for disconnect purposes, as it could be accidentally turned on from inside the house and start the unit unexpectedly.

MOUNTING

CAUTION: To reduce the risk of damage to your home, please ensure that the mounting surface is strong enough to support the operating weight of this cooler. DO NOT plug in the cooler until installation is complete and the unit has been tested for rigidity.
To install this cooler, the following tools are required.

To install this cooler, the following tools are required.

• Adjustable wrenches siguientes se requieren.
• Screwdrivers

1. With the louver removed, place the cooler in the center of the window opening. Lower the window to rest behind the top duct flange as shown.
2. Pull out the spacer rods (A) so as to allow the rubber feet (B) to rest against the house siding. Tighten the screw (C) in the spacer rod bracket (D).
3. Fasten a stop above the inside window sash to prevent the window from being raised, causing the cooler to fall.
4. Adjust the spacer rods so the cooler is level. This will ensure proper water flow to the filters.
5. Install the side sealer panels (G). These panels are the correct height, but may need to be trimmed to fit the width of your window.
6. a) Trim the side sealers so they are ½ inch wider than is needed to reach the edge of your window frame.
7. b) Loosen the 4 screws holding the grille (F) to the duct 2 or 3 turns. Leave enough room to slide the side sealers between the grille and the duct (E) as shown.
8. c) Line up the slots in the side sealers with the screws in the grille, and slide the side sealers behind the grille.
9. d) Tighten the screws holding the grille to the duct. Install chain supports (NOT PROVIDED) See picture page 2
10. e) Drill pilot holes in the window frame 3 feet above the top of the cooler and the width of the cooler apart. Install screw hooks to the full depth of the threads.
11. f) Hook one end of each chain over each screw hook.
12. g) Place the “S” hooks in the holes provided at the top and back of the cooler.
13. h) Place the opposite end of the “S” hooks in the free end of each chain. Make sure that the chains are taught, but not tight enough to pull the bottom of the cooler away from the wall.

INSTALL OVERFLOW AND DRAIN

1. Slide rubber washer (J) over the drain bushing (I) and push through the hole in the bottom of the cooler (K) from the top side.
2. Secure it from below with the lock nut (L). Make sure the rubber washer does not twist while tightening, which could cause it to leak. DO NOT OVERTIGHTEN.
3. Push the plastic overflow pipe (H) into drain bushing and hand tighten snugly.
4. If leakage occurs after the reservoir is full, retighten either the nut or overflow pipe until leaking stops. Sealers can be used if necessary.

FLOAT VALVE INSTALLATION

1. Place the float valve (M) in the bracket inside cooler as shown. Be sure that the float valve moves freely up and down.
2. Tighten the brass ring nut (O).
3. Slide the water tubing through the bushing in the side of the unit.
4. Slide the compression nut (Q) and the ferrule (P) onto the water tubing.
5. Place the water tubing in the end of the float valve and tighten the compression nut. Over tightening the compression nut may cause the connection to leak.

WATER LINE CONNECTION

1. Find the closest outside water faucet (T), and install a water connection kit as shown (not supplied with cooler).
2. Screw the sillcock (R) and water supply valve (S) on to the faucet.
3. Place the ferrule (P) and compression nut (Q) on the water tubing as shown.
4. Place the end of the water tubing into the sillcock and tighten the compression nut. Over tightening may cause the connection to leak.
5. Use the water supply valve to turn the water on and off at the faucet. This will allow a constant supply of water to the cooler. Use the sillcock to shut off the water to the cooler.
6. Turn the water on at the faucet and recheck all water line connections for leaks.

ADJUSTING THE WATER LEVEL

To adjust the water level, bend the float valve rod as necessary. Make sure that the float valve cuts off completely when the water level has been reached; If not water can build up in the reservoir and run out the over flow pipe. When the reservoir is full, check the overflow assembly for leaks.

STARTUP

1. Plug the electrical cord into a standard grounded receptacle.
2. Open the windows, a couple of inches, in rooms where you want cooling to be directed.
3. Turn the cooler to either the high or low cooling position and check to see if water is flowing from the water trays and the cooling pads are wetting out evenly.
4. On cool nights or when humidity is at a high level, the water pump can be turned off, and the cooler can be used for ventilation purposes.

NOTE
To eliminate the delivery of hot air when starting the cooler, turn on the pump only for the first few minutes.

MAINTENANCE

Unplug the cooler before attempting to open or service it.
The unit has an automatic thermally protected motor.
If it shuts off on its own for any reason, It can start back up without warning!

NOTE: This motor is thermally protected with an automatic reset. The motor will automatically stop if it is overloaded.
After the motor cools, it will start again automatically. If this occurs, check into the problem immediately before permanent damage occurs.

• Occasionally inspect your cooler for leaks, blocked water lines, or excessive residue build-up on the pads.
• At the end of the season, drain the reservoir. Remove the drainpipe and let water and dirt pass through the drain fitting

DO NOT GET WATER ON MOTOR OR PUMP MOTOR

Lime build-up can occur in the water reservoir and on ouvers. Clean this off at least once per season. If any rust or bare metal spots occur on the cabinet or louver, the metal should be sanded, primed and painted with a good quality paint.

Wiring diagram

NOTE:
Depending on the mineral content of the water or the amount of airborne dust in your area, you may need to replace filter pads during the season.
It is best to replace filter pads again at the end of the season.

Old filter pads soak up lime and salts, which can rust the louvers and the cabinet during the winter months.

TO REPLACE PADS

1. Remove the louver (U) from the cooler.
2. Unhook pad holders (V) at the sides of the louver and above and below side pads inside the cooler.
3. Remove old pads (W) and discard them.
4. Tuck in the rear pad to make sure hot air can not by-pass filter
5. Place pad holders over the new pad and hook them into place.
6. For the side pads, center pad over louver openings in the cabinet, hook pad holder below the pad, tilt into place, and hook at the top.
