To install the unit the following tools are needed: • 5132" hax key allen wrench Channel locks • Pliers • Adjustable wrenches Tubing cutter Screwdrivers • Hammer 114" Socket wrench • 7/16" Socket wrench Before attempting to install the cooler, make sure the following preparations have been made: • Assure that the mounting sudace is strong enough to bear the weight of the cooler when in use; remember that when the system fills with water, the cooler will be much heavier than when dry. The operating weight for MC units is 250 pounds, and for HC units is 295 pounds. Make sure you have adequate means for lifting the cooler in place. Make sure the mounting sudt_ceis level in all directions. • Make sure any ductworkand electrical needs complywithlocal,state,county, and federalcodes. Caution: Aft electrical in- with local buflding and safety codes, and must be stallations must comply performed by qualified personnel only. , Mounting The blower module and the media module can be separated before mounting by removing tour bolts and one sh_ppingscrew -see drawing below. Placement and Securing port the unit and secure it to the roof. For High-Performance models HC43. HC44. HC63 and HC64 we recommend that a full stand be constructed in such a manner as to support the entire perimeter of the cooler. A leg kit only may not provide adequate support for these mode!s due to their increased size and weight. Place the cooler over the roof jack and position so that it is level. Carefully seal the space between the roof jack and bottom of cooler with caulking compound, silicone, asphalt or industrial sealing tape to prevent air leakage, Then carefully seal the roof jack to roof with asphalt or caulking compound to prevent air leakage from cooler or rain water from leaking into mot. (See Figure 1). There should be 24 inches clearance on all sides of the cooler for maintenance. For maximum cooling performance and even water distribution, the cooler must be level. The base of the cooler at the drain fitting should have at least 4" clearance to allow drain installation. Electrical Connections For the convenience of thermostat control, we recommend installing a MasterStat TM Universal Cooler Control Kit, Model CC1000A. Complete installation instructions are furnished with the CC1000A Kit. For electrical connections to a rotary wall switch, use the following instructions: Locate the junction box installed in the dry module. Junction box is to be installed with the receptacle facing away from the pad. Make certain all electrical cords are clear of the belt, water, pulleys and blower wheel. Note that there ere two plug-ins, one for the motor and one for the pump. The building power supply must be connected to this iunction box to provide power to the motor and pump. The wiring diagram in Figure 1 shows how the junclion box receptacle should be connected to the power supply. Make sure contro switch and circuit breaker are in the OFF position. Low voltage electrical supply (below 105 V) may cause insufficient water supply to pad, ® Caution: Turn off afi electrical power to the cooler before attempting to install, open, or service your cooler. Grounding Install a ground wire to suitable ground according to local codes. Install Motor NOTE: A special MesterCool motor kit Is necessary for installation due to the custom designed receptacle In the junction box. 1. Adjust motor cradle spacing. 2. Place motor in cradle (see Figure 2). 3, Place straps over each end, connect to cradle and tighten. 4, Align sheave (motor pulley) with blower pulley by moving sheave in and out on motor shaft until visual alignment is achieved. Tighten alignment set screw to 125 in-lbs. Do not adjust to the point where the motor sheave comes in contact with the motor face plate (see Figure 2). Belt tensionshould be ad usted so the beltwi defect 1/21o3/4 nchatthecenter of the span per Figure 3. Re-adjust belt tension after any pulley adjustment. Replace worn or damaged belts.

Do not adjust belt tension by changing dlamefer of adjustable sheave. Adjust belt tension only by adjusting motor brackeL Rotate blower wheel by hand to see that it moves freely without rubbing against housing. Check motor mountinq to be sure all screws and nuts are tightened down. If cooler is connected to ductwork, air delivery and motor amperage will be decreased due to increased duct resistance. To compensate for this, the motor pulley is adjusted out or in. using an ammeter to check motor amperage. For maximum air flow check motor amperage with all service panels in place. To prevent overloading of the motor, check amperage with all windows and doors open and all relief systems operating. Tighten pulley set screw to 125 in-lbs. A qualified serviceman is required to adjust motor before start-up. maximum amperage output as stamped the moCaution: Do not on exceed tor specification plate or motor can overload. Only qualified persons with proper electrical equipment and knowledge should adjust variable pitch sheaves. Do not allow water to get on the motor, as it will burn out the windings. Connect Water Supply Connect water line to cooler as follows: • A water valve should be installed at a convenient location, to allow the water supply to be turned on and off. 1/4" tubing is used to provide water to the cooler. A water connector kit, availubte from your dealer provides the necessary items. • Install float valve in the side panel of the wet section opposite the pump. • Place tube nut and ferrule over end of tubing. • Insert tube into float valve, and tighten to Secure. qOTE: Soft water equipment should not be mttached to any water lines going "to a ooler. "Soft Water" will cause corrosion md decrease effective life of cooler. Figure $ COMPRESSION NUT FERRULE • _. _RULE___ Fasten 1/4 inch water supply line to cooler stand using tubing clamp and self-drilling screw. Locate tubing clamp 18 inches or less from water supply line entry into cabinet. (See Figure 5A) Note on multi-speed switches: A switch with separate terminals for the pump is recommended. Install Overflow Standpipe and Drain Line Install overflow drain bushing in bottom wet section on the right side. Screw plastic overflow standpipe into the drain bushing and tighten snugly. Slide rubber washer over drain bushing, push through bottom of cooler, and tighten nut, Connect a permanent drain (copper/pvc/garden hose) to the drain bushing for draining the unit and overflow protection. Drain should be in accordance with local plumbing codes. f SI_LF-DRtLUNG SCREW 1/4" WATER SUPPly LINE Faucet Use Connect water line to water supply, as follows (refer to Figure 6). • Install a sillcock and water valve on faucet, as shown. Place tubing nut and ferrule on tube end and insed in valve. Tighten nuts on valve and tube. l( faucet is not to be used for water supply, instal lvalve on water line to be used. Follow instructions above for securing tubing to valve. FTgure4 Figure 6 FAUCET .,_,_ , Adjusting Water Level and Float Valve Fill reservoir as follows: • Turn water supply on. Check for good pressure and flow from float valve. • When float valve shuts off. check water level. Water level should be from 1/2 to 1 inch below top edge of overflow standpipe. It may be necessary to adjust float valve by bending the rod (refer to Figure 5). • Check reservoir and all connections for leaks. Install Bleed-Off A bleed-off system is provided with your MastsrCoo| cooler. We recommend the bleed-off be installed and maintained while operating this unit. Its purpose is to eliminate a small quantity of water from recirculatlon thus reducing scale build-up. Install bleed-off as Rgure 7 follows: • Install 1/4" black plastic tubing into pump as shown in Figure 7. • Insert smaller black plastic tubing into 114" tubing as shown in Figure 7. Adjust bleed-off by shortening smalltube to get the proper bleed rate shown below. Disposal of bleed-off water shouldcomply with local codes. Use of chemical additives or any water treatment other than bleed-off is not recommended for thiscooler. Failure to use the bleed-off with MasterCool pad greatly increases the mineral deposits and reduces the expected life of the MasterCool pad. and could result in early replacement of pad at your expense.

Start-up and shutdown servicing should never be ovedooked. Add-On Coolers Coolers come in a wide array of sizes, horsepower, and capacities, suitable for patio, garage, guestroom, and so fodh, More than one cooler in a single home improves the cooling effectiveness of the system. Owners of refrigerated air conditioning have found that the addition of an evaporative cooler vastly reduces their electric bills. Insulation Once your cooler forces cooled air into your home and pushes the hot air out, good insulation around your ductwork will keep the air as cool as possible. Whola-house insulation will prevent heat from seeping in and will also improve cooling comfort. Motor The cooling rate can be controlled by increasing and reducing the amount of cooled air blown into your home. Two-speed motors allow you to use higher speeds during the hottest pad of the day, lower speeds for milder temperatures. _d I needed. ,,wt_ben_-rit_ace puny. • Your evaporative cooler is a finely crafted, economically operating unit built on decades of know-how and reseamh.
